| 345 | </para> | ||
| 346 | <para>In a system with multiple front-ends, it is usually the case that multiple devices | ||
| 347 | cannot be open in read/write mode simultaneously. As long as a front-end | ||
| 348 | device is opened in read/write mode, other open() calls in read/write mode will | ||
| 349 | either fail or block, depending on whether non-blocking or blocking mode was | ||
| 350 | specified. A front-end device opened in blocking mode can later be put into | ||
| 351 | non-blocking mode (and vice versa) using the F_SETFL command of the fcntl | ||
| 352 | system call. This is a standard system call, documented in the Linux manual | ||
| 353 | page for fcntl. When an open() call has succeeded, the device will be ready | ||
| 354 | for use in the specified mode. This implies that the corresponding hardware is | ||
| 355 | powered up, and that other front-ends may have been powered down to make | ||
| 356 | that possible.</para> | ||

| 24 | <para>The first API for DVB cards we used at Convergence in late 1999 | ||
| 25 | was an extension of the Video4Linux API which was primarily developed | ||
| 26 | for frame grabber cards. As such it was not really well suited to be | ||
| 27 | used for DVB cards and their new features like recording MPEG streams | ||
| 28 | and filtering several section and PES data streams at the same time. | ||
| 29 | </para> | ||
| 30 | |||
| 31 | <para>In early 2000, we were approached by Nokia with a proposal for a | ||
| 32 | new standard Linux DVB API. As a commitment to the development of | ||
| 33 | terminals based on open standards, Nokia and Convergence made it | ||
| 34 | available to all Linux developers and published it on | ||
| 35 | <ulink url="http://www.linuxtv.org/" /> in September 2000. | ||
| 36 | Convergence is the maintainer of the Linux DVB API. Together with the | ||
| 37 | LinuxTV community (i.e. you, the reader of this document), the Linux DVB | ||
| 38 | API will be constantly reviewed and improved. With the Linux driver for | ||
| 39 | the Siemens/Hauppauge DVB PCI card Convergence provides a first | ||
| 40 | implementation of the Linux DVB API.</para> | ||

| 67 | or antenna or directly from cable. The frontend down-converts and | ||
| 68 | demodulates this signal into an MPEG transport stream (TS). In case of a | ||
| 69 | satellite frontend, this includes a facility for satellite equipment | ||
| 70 | control (SEC), which allows control of LNB polarization, multi feed | ||

| 123 | devices control the MPEG2 decoder hardware, the frontend device the | ||

| 127 | the CA device controls all the conditional access capabilities of the | ||

| 459 | <title>Demux API</title> | ||
| 460 | <para>The demux API should be implemented for each demux in the system. It is used to select | ||
| 461 | the TS source of a demux and to manage the demux resources. When the demux | ||
| 462 | client allocates a resource via the demux API, it receives a pointer to the API of that | ||
| 463 | resource. | ||
| 464 | </para> | ||
| 465 | <para>Each demux receives its TS input from a DVB front-end or from memory, as set via the | ||
| 466 | demux API. In a system with more than one front-end, the API can be used to select one of | ||
| 467 | the DVB front-ends as a TS source for a demux, unless this is fixed in the HW platform. The | ||
| 468 | demux API only controls front-ends regarding their connections with demuxes; the APIs | ||
| 469 | used to set the other front-end parameters, such as tuning, are not defined in this | ||
| 470 | document. | ||
| 471 | </para> | ||
| 472 | <para>The functions that implement the abstract interface demux should be defined static or | ||
| 473 | module private and registered to the Demux Directory for external access. It is not necessary | ||
| 474 | to implement every function in the demux_t struct, however (for example, a demux interface | ||
| 475 | might support Section filtering, but not TS or PES filtering). The API client is expected to | ||
| 476 | check the value of any function pointer before calling the function: the value of NULL means | ||
| 477 | “function not available”. | ||
| 478 | </para> | ||
| 479 | <para>Whenever the functions of the demux API modify shared data, the possibilities of lost | ||
| 480 | update and race condition problems should be addressed, e.g. by protecting parts of code with | ||
| 481 | mutexes. This is especially important on multi-processor hosts. | ||
| 482 | </para> | ||
| 483 | <para>Note that functions called from a bottom half context must not sleep, at least in the 2.2.x | ||
| 484 | kernels. Even a simple memory allocation can result in a kernel thread being put to sleep if | ||
| 485 | swapping is needed. For example, the Linux kernel calls the functions of a network device | ||
| 486 | interface from a bottom half context. Thus, if a demux API function is called from network | ||
| 487 | device code, the function must not sleep. | ||

| 1471 | <para>This kernel-space API comprises the callback functions that deliver filtered data to the | ||
| 1472 | demux client. Unlike the other APIs, these API functions are provided by the client and called | ||
| 1473 | from the demux code. | ||
| 1474 | </para> | ||
| 1475 | <para>The function pointers of this abstract interface are not packed into a structure as in the | ||
| 1476 | other demux APIs, because the callback functions are registered and used independent | ||
| 1477 | of each other. As an example, it is possible for the API client to provide several | ||
| 1478 | callback functions for receiving TS packets and no callbacks for PES packets or | ||
| 1479 | sections. | ||
| 1480 | </para> | ||
| 1481 | <para>The functions that implement the callback API need not be re-entrant: when a demux | ||
| 1482 | driver calls one of these functions, the driver is not allowed to call the function again before | ||
| 1483 | the original call returns. If a callback is triggered by a hardware interrupt, it is recommended | ||
| 1484 | to use the Linux “bottom half” mechanism or start a tasklet instead of making the callback | ||
| 1485 | function call directly from a hardware interrupt. | ||

| 1635 | <para>This function, provided by the client of the demux API, is called from the | ||
| 1636 | demux code. The function is only called when filtering of sections has been | ||
| 1637 | enabled using the function start_filtering() of the section feed API. When the | ||
| 1638 | demux driver has received a complete section that matches at least one section | ||
| 1639 | filter, the client is notified via this callback function. Normally this function is | ||
| 1640 | called for each received section; however, it is also possible to deliver multiple | ||
| 1641 | sections with one callback, for example when the system load is high. If an | ||
| 1642 | error occurs while receiving a section, this function should be called with | ||
| 1643 | the corresponding error type set in the success field, whether or not there is | ||
| 1644 | data to deliver. The Section Feed implementation should maintain a circular | ||
| 1645 | buffer for received sections. However, this is not necessary if the Section Feed | ||
| 1646 | API is implemented as a client of the TS Feed API, because the TS Feed | ||
| 1647 | implementation then buffers the received data. The size of the circular buffer | ||
| 1648 | can be configured using the set() function in the Section Feed API. If there | ||
| 1649 | is no room in the circular buffer when a new section is received, the section | ||
| 1650 | must be discarded. If this happens, the value of the success parameter should | ||
| 1651 | be DMX_OVERRUN_ERROR on the next callback.</para> | ||

| 2069 | <para>The bitfields filter_mask and filter_value should only be modified when no | ||

| 2071 | filter_value are compared with the section headers/payload. On a binary value | ||
| 2072 | of 1 in filter_mask, the corresponding bits are compared. The filter only accepts | ||
| 2073 | sections that are equal to filter_value in all the tested bit positions. Any changes | ||

| 2089 | suffice. Additionally, software-only section filters can optionally be allocated | ||
| 2090 | to clients when all hardware section filters are in use. Note that on most demux | ||
| 2091 | hardware it is not possible to filter on the section_length field of the section | ||

| 51 | <para>This document covers the Linux Kernel to Userspace API's used by | ||
| 52 | video and radio straming devices, including video cameras, | ||
| 53 | analog and digital TV receiver cards, AM/FM receiver cards, | ||
| 54 | streaming capture devices.</para> | ||
| 55 | <para>It is divided into three parts.</para> | ||
| 56 | <para>The first part covers radio, capture, | ||
| 57 | cameras and analog TV devices.</para> | ||
| 58 | <para>The second part covers the | ||
| 59 | API used for digital TV and Internet reception via one of the | ||
| 60 | several digital tv standards. While it is called as DVB API, | ||
| 61 | in fact it covers several different video standards including | ||
| 62 | DVB-T, DVB-S, DVB-C and ATSC. The API is currently being updated | ||
| 63 | to documment support also for DVB-S2, ISDB-T and ISDB-S.</para> | ||
| 64 | <para>The third part covers other API's used by all media infrastructure devices</para> | ||
| 65 | <para>For additional information and for the latest development code, | ||

| 37 | <title>Device Naming</title> | ||
| 38 | |||
| 39 | <para>V4L2 drivers are implemented as kernel modules, loaded | ||
| 40 | manually by the system administrator or automatically when a device is | ||
| 41 | first opened. The driver modules plug into the "videodev" kernel | ||
| 42 | module. It provides helper functions and a common application | ||
| 43 | interface specified in this document.</para> | ||
| 44 | |||
| 45 | <para>Each driver thus loaded registers one or more device nodes | ||
| 46 | with major number 81 and a minor number between 0 and 255. Assigning | ||
| 47 | minor numbers to V4L2 devices is entirely up to the system administrator, | ||
| 48 | this is primarily intended to solve conflicts between devices.<footnote> | ||
| 49 | <para>Access permissions are associated with character | ||
| 50 | device special files, hence we must ensure device numbers cannot | ||
| 51 | change with the module load order. To this end minor numbers are no | ||
| 52 | longer automatically assigned by the "videodev" module as in V4L but | ||
| 53 | requested by the driver. The defaults will suffice for most people | ||
| 54 | unless two drivers compete for the same minor numbers.</para> | ||
| 55 | </footnote> The module options to select minor numbers are named | ||
| 56 | after the device special file with a "_nr" suffix. For example "video_nr" | ||
| 57 | for <filename>/dev/video</filename> video capture devices. The number is | ||
| 58 | an offset to the base minor number associated with the device type. | ||
| 59 | <footnote> | ||
| 60 | <para>In earlier versions of the V4L2 API the module options | ||
| 61 | where named after the device special file with a "unit_" prefix, expressing | ||
| 62 | the minor number itself, not an offset. Rationale for this change is unknown. | ||
| 63 | Lastly the naming and semantics are just a convention among driver writers, | ||
| 64 | the point to note is that minor numbers are not supposed to be hardcoded | ||
| 65 | into drivers.</para> | ||
| 66 | </footnote> When the driver supports multiple devices of the same | ||
| 67 | type more than one minor number can be assigned, separated by commas: | ||
| 68 | <informalexample> | ||
| 69 | <screen> | ||
| 70 | > insmod mydriver.o video_nr=0,1 radio_nr=0,1</screen> | ||
| 71 | </informalexample></para> | ||
| 72 | |||
| 73 | <para>In <filename>/etc/modules.conf</filename> this may be | ||
| 74 | written as: <informalexample> | ||
| 75 | <screen> | ||
| 76 | alias char-major-81-0 mydriver | ||

| 100 | |||
| 101 | <para>By convention system administrators create various | ||

| 107 | <para>The creation of character special files (with | ||
| 108 | <application>mknod</application>) is a privileged operation and | ||
| 109 | devices cannot be opened by major and minor number. That means | ||
| 110 | applications cannot <emphasis>reliable</emphasis> scan for loaded or | ||
| 111 | installed drivers. The user must enter a device name, or the | ||
| 112 | application can try the conventional device names.</para> | ||
| 113 | |||
| 114 | <para>Under the device filesystem (devfs) the minor number | ||
| 115 | options are ignored. V4L2 drivers (or by proxy the "videodev" module) | ||

| 118 | names above.</para> | ||

| 121 | <section id="related"> | ||
| 122 | <title>Related Devices</title> | ||
| 123 | |||
| 124 | <para>Devices can support several related functions. For example | ||
| 125 | video capturing, video overlay and VBI capturing are related because | ||
| 126 | these functions share, amongst other, the same video input and tuner | ||
| 127 | frequency. V4L and earlier versions of V4L2 used the same device name | ||
| 128 | and minor number for video capturing and overlay, but different ones | ||
| 129 | for VBI. Experience showed this approach has several problems<footnote> | ||
| 130 | <para>Given a device file name one cannot reliable find | ||
| 131 | related devices. For once names are arbitrary and in a system with | ||
| 132 | multiple devices, where only some support VBI capturing, a | ||
| 133 | <filename>/dev/video2</filename> is not necessarily related to | ||
| 134 | <filename>/dev/vbi2</filename>. The V4L | ||
| 135 | <constant>VIDIOCGUNIT</constant> ioctl would require a search for a | ||
| 136 | device file with a particular major and minor number.</para> | ||
| 137 | </footnote>, and to make things worse the V4L videodev module | ||
| 138 | used to prohibit multiple opens of a device.</para> | ||
| 139 | |||
| 140 | <para>As a remedy the present version of the V4L2 API relaxed the | ||
| 141 | concept of device types with specific names and minor numbers. For | ||
| 142 | compatibility with old applications drivers must still register different | ||
| 143 | minor numbers to assign a default function to the device. But if related | ||
| 144 | functions are supported by the driver they must be available under all | ||
| 145 | registered minor numbers. The desired function can be selected after | ||
| 146 | opening the device as described in <xref linkend="devices" />.</para> | ||
| 147 | |||
| 148 | <para>Imagine a driver supporting video capturing, video | ||
| 149 | overlay, raw VBI capturing, and FM radio reception. It registers three | ||
| 150 | devices with minor number 0, 64 and 224 (this numbering scheme is | ||
| 151 | inherited from the V4L API). Regardless if | ||
| 152 | <filename>/dev/video</filename> (81, 0) or | ||
| 153 | <filename>/dev/vbi</filename> (81, 224) is opened the application can | ||
| 154 | select any one of the video capturing, overlay or VBI capturing | ||
| 155 | functions. Without programming (e. g. reading from the device | ||
| 156 | with <application>dd</application> or <application>cat</application>) | ||
| 157 | <filename>/dev/video</filename> captures video images, while | ||
| 158 | <filename>/dev/vbi</filename> captures raw VBI data. | ||
| 159 | <filename>/dev/radio</filename> (81, 64) is invariable a radio device, | ||
| 160 | unrelated to the video functions. Being unrelated does not imply the | ||
| 161 | devices can be used at the same time, however. The &func-open; | ||
| 162 | function may very well return an &EBUSY;.</para> | ||
| 163 | |||
| 164 | <para>Besides video input or output the hardware may also | ||
| 165 | support audio sampling or playback. If so, these functions are | ||
| 166 | implemented as OSS or ALSA PCM devices and eventually OSS or ALSA | ||
| 167 | audio mixer. The V4L2 API makes no provisions yet to find these | ||
| 168 | related devices. If you have an idea please write to the linux-media | ||
| 169 | mailing list: &v4l-ml;.</para> | ||

| 171 | |||
| 172 | <section> | ||
| 173 | <title>Multiple Opens</title> | ||
| 174 | |||
| 175 | <para>In general, V4L2 devices can be opened more than once. | ||
| 176 | When this is supported by the driver, users can for example start a | ||
| 177 | "panel" application to change controls like brightness or audio | ||
| 178 | volume, while another application captures video and audio. In other words, panel | ||
| 179 | applications are comparable to an OSS or ALSA audio mixer application. | ||
| 180 | When a device supports multiple functions like capturing and overlay | ||
| 181 | <emphasis>simultaneously</emphasis>, multiple opens allow concurrent | ||
| 182 | use of the device by forked processes or specialized applications.</para> | ||
| 183 | |||
| 184 | <para>Multiple opens are optional, although drivers should | ||
| 185 | permit at least concurrent accesses without data exchange, &ie; panel | ||
| 186 | applications. This implies &func-open; can return an &EBUSY; when the | ||
| 187 | device is already in use, as well as &func-ioctl; functions initiating | ||
| 188 | data exchange (namely the &VIDIOC-S-FMT; ioctl), and the &func-read; | ||
| 189 | and &func-write; functions.</para> | ||
| 190 | |||
| 191 | <para>Mere opening a V4L2 device does not grant exclusive | ||
| 192 | access.<footnote> | ||
| 193 | <para>Drivers could recognize the | ||
| 194 | <constant>O_EXCL</constant> open flag. Presently this is not required, | ||
| 195 | so applications cannot know if it really works.</para> | ||
| 196 | </footnote> Initiating data exchange however assigns the right | ||
| 197 | to read or write the requested type of data, and to change related | ||
| 198 | properties, to this file descriptor. Applications can request | ||
| 199 | additional access privileges using the priority mechanism described in | ||
| 200 | <xref linkend="app-pri" />.</para> | ||

| 203 | <section> | ||
| 204 | <title>Shared Data Streams</title> | ||
| 205 | |||
| 206 | <para>V4L2 drivers should not support multiple applications | ||
| 207 | reading or writing the same data stream on a device by copying | ||
| 208 | buffers, time multiplexing or similar means. This is better handled by | ||
| 209 | a proxy application in user space. When the driver supports stream | ||
| 210 | sharing anyway it must be implemented transparently. The V4L2 API does | ||
| 211 | not specify how conflicts are solved. <!-- For example O_EXCL when the | ||
| 212 | application does not want to be preempted, PROT_READ mmapped buffers | ||
| 213 | which can be mapped twice, what happens when image formats do not | ||
| 214 | match etc.--></para> | ||

| 220 | <para>To open and close V4L2 devices applications use the | ||
| 221 | &func-open; and &func-close; function, respectively. Devices are | ||
| 222 | programmed using the &func-ioctl; function as explained in the | ||

| 229 | |||
| 230 | <para>Because V4L2 covers a wide variety of devices not all | ||
| 231 | aspects of the API are equally applicable to all types of devices. | ||
| 232 | Furthermore devices of the same type have different capabilities and | ||

| 521 | <para>V4L2 defines one bit for each analog video standard | ||

| 529 | <para>Many of the defined standards are actually just variations | ||

| 539 | choice. Similar a Composite input may collapse standards, enumerating | ||
| 540 | "PAL-B/G/H/I", "NTSC-M" and "SECAM-D/K".<footnote> | ||
| 541 | <para>Some users are already confused by technical terms PAL, | ||
| 542 | NTSC and SECAM. There is no point asking them to distinguish between | ||
| 543 | B, G, D, or K when the software or hardware can do that | ||

| 545 | </footnote></para> | ||
| 546 | |||
| 547 | <para>To query and select the standard used by the current video | ||

| 550 | standard can be sensed with the &VIDIOC-QUERYSTD; ioctl. Note parameter of all these ioctls is a pointer to a &v4l2-std-id; type (a standard set), <emphasis>not</emphasis> an index into the standard enumeration.<footnote> | ||
| 551 | <para>An alternative to the current scheme is to use pointers | ||
| 552 | to indices as arguments of <constant>VIDIOC_G_STD</constant> and | ||
| 553 | <constant>VIDIOC_S_STD</constant>, the &v4l2-input; and | ||

| 555 | indices like <structfield>audioset</structfield>.</para> | ||
| 556 | <para>Indices are consistent with the rest of the API | ||
| 557 | and identify the standard unambiguously. In the present scheme of | ||
| 558 | things an enumerated standard is looked up by &v4l2-std-id;. Now the | ||
| 559 | standards supported by the inputs of a device can overlap. Just | ||
| 560 | assume the tuner and composite input in the example above both | ||
| 561 | exist on a device. An enumeration of "PAL-B/G", "PAL-H/I" suggests | ||
| 562 | a choice which does not exist. We cannot merge or omit sets, because | ||
| 563 | applications would be unable to find the standards reported by | ||
| 564 | <constant>VIDIOC_G_STD</constant>. That leaves separate enumerations | ||
| 565 | for each input. Also selecting a standard by &v4l2-std-id; can be | ||
| 566 | ambiguous. Advantage of this method is that applications need not | ||
| 567 | identify the standard indirectly, after enumerating.</para><para>So in | ||
| 568 | summary, the lookup itself is unavoidable. The difference is only | ||
| 569 | whether the lookup is necessary to find an enumerated standard or to | ||

| 727 | <title>Data Format Negotiation</title> | ||
| 728 | |||
| 729 | <para>Different devices exchange different kinds of data with | ||
| 730 | applications, for example video images, raw or sliced VBI data, RDS | ||
| 731 | datagrams. Even within one kind many different formats are possible, | ||
| 732 | in particular an abundance of image formats. Although drivers must | ||
| 733 | provide a default and the selection persists across closing and | ||
| 734 | reopening a device, applications should always negotiate a data format | ||
| 735 | before engaging in data exchange. Negotiation means the application | ||
| 736 | asks for a particular format and the driver selects and reports the | ||
| 737 | best the hardware can do to satisfy the request. Of course | ||
| 738 | applications can also just query the current selection.</para> | ||
| 739 | |||
| 740 | <para>A single mechanism exists to negotiate all data formats | ||
| 741 | using the aggregate &v4l2-format; and the &VIDIOC-G-FMT; and | ||
| 742 | &VIDIOC-S-FMT; ioctls. Additionally the &VIDIOC-TRY-FMT; ioctl can be | ||
| 743 | used to examine what the hardware <emphasis>could</emphasis> do, | ||
| 744 | without actually selecting a new data format. The data formats | ||
| 745 | supported by the V4L2 API are covered in the respective device section | ||
| 746 | in <xref linkend="devices" />. For a closer look at image formats see | ||
| 747 | <xref linkend="pixfmt" />.</para> | ||
| 748 | |||
| 749 | <para>The <constant>VIDIOC_S_FMT</constant> ioctl is a major | ||
| 750 | turning-point in the initialization sequence. Prior to this point | ||
| 751 | multiple panel applications can access the same device concurrently to | ||
| 752 | select the current input, change controls or modify other properties. | ||
| 753 | The first <constant>VIDIOC_S_FMT</constant> assigns a logical stream | ||
| 754 | (video data, VBI data etc.) exclusively to one file descriptor.</para> | ||
| 755 | |||
| 756 | <para>Exclusive means no other application, more precisely no | ||
| 757 | other file descriptor, can grab this stream or change device | ||
| 758 | properties inconsistent with the negotiated parameters. A video | ||
| 759 | standard change for example, when the new standard uses a different | ||
| 760 | number of scan lines, can invalidate the selected image format. | ||
| 761 | Therefore only the file descriptor owning the stream can make | ||
| 762 | invalidating changes. Accordingly multiple file descriptors which | ||
| 763 | grabbed different logical streams prevent each other from interfering | ||
| 764 | with their settings. When for example video overlay is about to start | ||
| 765 | or already in progress, simultaneous video capturing may be restricted | ||
| 766 | to the same cropping and image size.</para> | ||
| 767 | |||
| 768 | <para>When applications omit the | ||
| 769 | <constant>VIDIOC_S_FMT</constant> ioctl its locking side effects are | ||
| 770 | implied by the next step, the selection of an I/O method with the | ||
| 771 | &VIDIOC-REQBUFS; ioctl or implicit with the first &func-read; or | ||
| 772 | &func-write; call.</para> | ||
| 773 | |||
| 774 | <para>Generally only one logical stream can be assigned to a | ||
| 775 | file descriptor, the exception being drivers permitting simultaneous | ||
| 776 | video capturing and overlay using the same file descriptor for | ||
| 777 | compatibility with V4L and earlier versions of V4L2. Switching the | ||
| 778 | logical stream or returning into "panel mode" is possible by closing | ||
| 779 | and reopening the device. Drivers <emphasis>may</emphasis> support a | ||
| 780 | switch using <constant>VIDIOC_S_FMT</constant>.</para> | ||
| 781 | |||
| 782 | <para>All drivers exchanging data with | ||

| 905 | <title>Scaling Adjustments</title> | ||
| 906 | |||
| 907 | <para>Video hardware can have various cropping, insertion and | ||
| 908 | scaling limitations. It may only scale up or down, support only | ||
| 909 | discrete scaling factors, or have different scaling abilities in | ||
| 910 | horizontal and vertical direction. Also it may not support scaling at | ||
| 911 | all. At the same time the &v4l2-crop; rectangle may have to be | ||
| 912 | aligned, and both the source and target rectangles may have arbitrary | ||
| 913 | upper and lower size limits. In particular the maximum | ||
| 914 | <structfield>width</structfield> and <structfield>height</structfield> | ||
| 915 | in &v4l2-crop; may be smaller than the | ||
| 916 | &v4l2-cropcap;.<structfield>bounds</structfield> area. Therefore, as | ||
| 917 | usual, drivers are expected to adjust the requested parameters and | ||
| 918 | return the actual values selected.</para> | ||
| 919 | |||
| 920 | <para>Applications can change the source or the target rectangle | ||
| 921 | first, as they may prefer a particular image size or a certain area in | ||
| 922 | the video signal. If the driver has to adjust both to satisfy hardware | ||
| 923 | limitations, the last requested rectangle shall take priority, and the | ||
| 924 | driver should preferably adjust the opposite one. The &VIDIOC-TRY-FMT; | ||
| 925 | ioctl however shall not change the driver state and therefore only | ||
| 926 | adjust the requested rectangle.</para> | ||
| 927 | |||
| 928 | <para>Suppose scaling on a video capture device is restricted to | ||
| 929 | a factor 1:1 or 2:1 in either direction and the target image size must | ||
| 930 | be a multiple of 16 × 16 pixels. The source cropping | ||
| 931 | rectangle is set to defaults, which are also the upper limit in this | ||
| 932 | example, of 640 × 400 pixels at offset 0, 0. An | ||
| 933 | application requests an image size of 300 × 225 | ||
| 934 | pixels, assuming video will be scaled down from the "full picture" | ||
| 935 | accordingly. The driver sets the image size to the closest possible | ||
| 936 | values 304 × 224, then chooses the cropping rectangle | ||
| 937 | closest to the requested size, that is 608 × 224 | ||
| 938 | (224 × 2:1 would exceed the limit 400). The offset | ||
| 939 | 0, 0 is still valid, thus unmodified. Given the default cropping | ||
| 940 | rectangle reported by <constant>VIDIOC_CROPCAP</constant> the | ||
| 941 | application can easily propose another offset to center the cropping | ||
| 942 | rectangle.</para> | ||
| 943 | |||
| 944 | <para>Now the application may insist on covering an area using a | ||
| 945 | picture aspect ratio closer to the original request, so it asks for a | ||
| 946 | cropping rectangle of 608 × 456 pixels. The present | ||
| 947 | scaling factors limit cropping to 640 × 384, so the | ||
| 948 | driver returns the cropping size 608 × 384 and adjusts | ||
| 949 | the image size to closest possible 304 × 192.</para> | ||

| 1137 | the &func-read; or &func-write;, which are not augmented by timestamps | ||
| 1138 | or sequence counters, and to avoid unneccessary data copying.</para> | ||

| 712 | drivers are not required to support this I/O method. Applications can | ||
| 713 | determine if the function is available with the &VIDIOC-QUERYCAP; | ||

| 719 | ioctls. V4L2 uses the general-purpose data format negotiation ioctls | ||

| 896 | |||
| 897 | <para>Soon after the V4L API was added to the kernel it was | ||
| 898 | criticised as too inflexible. In August 1998 Bill Dirks proposed a | ||
| 899 | number of improvements and began to work on documentation, example | ||
| 900 | drivers and applications. With the help of other volunteers this | ||
| 901 | eventually became the V4L2 API, not just an extension but a | ||
| 902 | replacement for the V4L API. However it took another four years and | ||
| 903 | two stable kernel releases until the new API was finally accepted for | ||
| 904 | inclusion into the kernel in its present form.</para> | ||

| 916 | &func-open; flag, and the aliases <constant>O_NONCAP</constant> and | ||
| 917 | <constant>O_NOIO</constant> were defined. Applications can set this | ||
| 918 | flag if they intend to access controls only, as opposed to capture | ||

| 1085 | <para>The &v4l2-buffer; <structfield>timestamp</structfield> | ||
| 1086 | was changed to a 64 bit integer, containing the sampling or output | ||
| 1087 | time of the frame in nanoseconds. Additionally timestamps will be in | ||
| 1088 | absolute system time, not starting from zero at the beginning of a | ||
| 1089 | stream. The data type name for timestamps is stamp_t, defined as a | ||
| 1090 | signed 64-bit integer. Output devices should not send a buffer out | ||
| 1091 | until the time in the timestamp field has arrived. I would like to | ||
| 1092 | follow SGI's lead, and adopt a multimedia timestamping system like | ||
| 1093 | their UST (Unadjusted System Time). See | ||
| 1094 | http://reality.sgi.com/cpirazzi_engr/lg/time/intro.html. [This link is | ||
| 1095 | no longer valid.] UST uses timestamps that are 64-bit signed integers | ||
| 1096 | (not struct timeval's) and given in nanosecond units. The UST clock | ||
| 1097 | starts at zero when the system is booted and runs continuously and | ||
| 1098 | uniformly. It takes a little over 292 years for UST to overflow. There | ||
| 1099 | is no way to set the UST clock. The regular Linux time-of-day clock | ||
| 1100 | can be changed periodically, which would cause errors if it were being | ||
| 1101 | used for timestamping a multimedia stream. A real UST style clock will | ||
| 1102 | require some support in the kernel that is not there yet. But in | ||
| 1103 | anticipation, I will change the timestamp field to a 64-bit integer, | ||
| 1104 | and I will change the v4l2_masterclock_gettime() function (used only | ||
| 1105 | by drivers) to return a 64-bit integer.</para> | ||

| 2334 | |||
| 2335 | <para>The X Video Extension (abbreviated XVideo or just Xv) is | ||
| 2336 | an extension of the X Window system, implemented for example by the | ||
| 2337 | XFree86 project. Its scope is similar to V4L2, an API to video capture | ||
| 2338 | and output devices for X clients. Xv allows applications to display | ||
| 2339 | live video in a window, send window contents to a TV output, and | ||
| 2340 | capture or output still images in XPixmaps<footnote> | ||
| 2341 | <para>This is not implemented in XFree86.</para> | ||
| 2342 | </footnote>. With their implementation XFree86 makes the | ||
| 2343 | extension available across many operating systems and | ||
| 2344 | architectures.</para> | ||
| 2345 | |||
| 2346 | <para>Because the driver is embedded into the X server Xv has a | ||
| 2347 | number of advantages over the V4L2 <link linkend="overlay">video | ||
| 2348 | overlay interface</link>. The driver can easily determine the overlay | ||
| 2349 | target, &ie; visible graphics memory or off-screen buffers for a | ||
| 2350 | destructive overlay. It can program the RAMDAC for a non-destructive | ||
| 2351 | overlay, scaling or color-keying, or the clipping functions of the | ||
| 2352 | video capture hardware, always in sync with drawing operations or | ||
| 2353 | windows moving or changing their stacking order.</para> | ||
| 2354 | |||
| 2355 | <para>To combine the advantages of Xv and V4L a special Xv | ||
| 2356 | driver exists in XFree86 and XOrg, just programming any overlay capable | ||
| 2357 | Video4Linux device it finds. To enable it | ||
| 2358 | <filename>/etc/X11/XF86Config</filename> must contain these lines:</para> | ||

| 2363 | |||
| 2364 | <para>As of XFree86 4.2 this driver still supports only V4L | ||
| 2365 | ioctls, however it should work just fine with all V4L2 devices through | ||
| 2366 | the V4L2 backward-compatibility layer. Since V4L2 permits multiple | ||
| 2367 | opens it is possible (if supported by the V4L2 driver) to capture | ||
| 2368 | video while an X client requested video overlay. Restrictions of | ||
| 2369 | simultaneous capturing and overlay are discussed in <xref | ||
| 2370 | linkend="overlay" /> apply.</para> | ||
| 2371 | |||
| 2372 | <para>Only marginally related to V4L2, XFree86 extended Xv to | ||
| 2373 | support hardware YUV to RGB conversion and scaling for faster video | ||
| 2374 | playback, and added an interface to MPEG-2 decoding hardware. This API | ||
| 2375 | is useful to display images captured with V4L2 devices.</para> | ||

| 2 | <title>User Controls</title> | ||
| 3 | |||
| 4 | <para>Devices typically have a number of user-settable controls | ||
| 5 | such as brightness, saturation and so on, which would be presented to | ||
| 6 | the user on a graphical user interface. But, different devices | ||
| 7 | will have different controls available, and furthermore, the range of | ||
| 8 | possible values, and the default value will vary from device to | ||
| 9 | device. The control ioctls provide the information and a mechanism to | ||
| 10 | create a nice user interface for these controls that will work | ||
| 11 | correctly with any device.</para> | ||
| 12 | |||
| 13 | <para>All controls are accessed using an ID value. V4L2 defines | ||
| 14 | several IDs for specific purposes. Drivers can also implement their | ||
| 15 | own custom controls using <constant>V4L2_CID_PRIVATE_BASE</constant> | ||
| 16 | and higher values. The pre-defined control IDs have the prefix | ||
| 17 | <constant>V4L2_CID_</constant>, and are listed in <xref | ||
| 18 | linkend="control-id" />. The ID is used when querying the attributes of | ||
| 19 | a control, and when getting or setting the current value.</para> | ||
| 20 | |||
| 21 | <para>Generally applications should present controls to the user | ||
| 22 | without assumptions about their purpose. Each control comes with a | ||
| 23 | name string the user is supposed to understand. When the purpose is | ||
| 24 | non-intuitive the driver writer should provide a user manual, a user | ||
| 25 | interface plug-in or a driver specific panel application. Predefined | ||
| 26 | IDs were introduced to change a few controls programmatically, for | ||
| 27 | example to mute a device during a channel switch.</para> | ||
| 28 | |||
| 29 | <para>Drivers may enumerate different controls after switching | ||
| 30 | the current video input or output, tuner or modulator, or audio input | ||
| 31 | or output. Different in the sense of other bounds, another default and | ||
| 32 | current value, step size or other menu items. A control with a certain | ||
| 33 | <emphasis>custom</emphasis> ID can also change name and | ||
| 34 | type.<footnote> | ||
| 35 | <para>It will be more convenient for applications if drivers | ||
| 36 | make use of the <constant>V4L2_CTRL_FLAG_DISABLED</constant> flag, but | ||
| 37 | that was never required.</para> | ||
| 38 | </footnote> Control values are stored globally, they do not | ||
| 39 | change when switching except to stay within the reported bounds. They | ||
| 40 | also do not change ⪚ when the device is opened or closed, when the | ||
| 41 | tuner radio frequency is changed or generally never without | ||
| 42 | application request. Since V4L2 specifies no event mechanism, panel | ||
| 43 | applications intended to cooperate with other panel applications (be | ||
| 44 | they built into a larger application, as a TV viewer) may need to | ||
| 45 | regularly poll control values to update their user | ||
| 46 | interface.<footnote> | ||
| 47 | <para>Applications could call an ioctl to request events. | ||
| 48 | After another process called &VIDIOC-S-CTRL; or another ioctl changing | ||
| 49 | shared properties the &func-select; function would indicate | ||
| 50 | readability until any ioctl (querying the properties) is | ||
| 51 | called.</para> | ||

| 441 | <title>Introduction</title> | ||
| 442 | |||
| 443 | <para>The control mechanism as originally designed was meant | ||
| 444 | to be used for user settings (brightness, saturation, etc). However, | ||
| 445 | it turned out to be a very useful model for implementing more | ||
| 446 | complicated driver APIs where each driver implements only a subset of | ||
| 447 | a larger API.</para> | ||
| 448 | |||
| 449 | <para>The MPEG encoding API was the driving force behind | ||
| 450 | designing and implementing this extended control mechanism: the MPEG | ||
| 451 | standard is quite large and the currently supported hardware MPEG | ||
| 452 | encoders each only implement a subset of this standard. Further more, | ||
| 453 | many parameters relating to how the video is encoded into an MPEG | ||
| 454 | stream are specific to the MPEG encoding chip since the MPEG standard | ||
| 455 | only defines the format of the resulting MPEG stream, not how the | ||
| 456 | video is actually encoded into that format.</para> | ||
| 457 | |||
| 458 | <para>Unfortunately, the original control API lacked some | ||
| 459 | features needed for these new uses and so it was extended into the | ||
| 460 | (not terribly originally named) extended control API.</para> | ||
| 461 | |||
| 462 | <para>Even though the MPEG encoding API was the first effort | ||
| 463 | to use the Extended Control API, nowadays there are also other classes | ||
| 464 | of Extended Controls, such as Camera Controls and FM Transmitter Controls. | ||
| 465 | The Extended Controls API as well as all Extended Controls classes are | ||
| 466 | described in the following text.</para> | ||
| 467 | </section> | ||
| 468 | |||
| 469 | <section> | ||
| 470 | <title>The Extended Control API</title> | ||
| 471 | |||
| 472 | <para>Three new ioctls are available: &VIDIOC-G-EXT-CTRLS;, | ||
| 473 | &VIDIOC-S-EXT-CTRLS; and &VIDIOC-TRY-EXT-CTRLS;. These ioctls act on | ||
| 474 | arrays of controls (as opposed to the &VIDIOC-G-CTRL; and | ||
| 475 | &VIDIOC-S-CTRL; ioctls that act on a single control). This is needed | ||
| 476 | since it is often required to atomically change several controls at | ||
| 477 | once.</para> | ||
| 478 | |||
| 479 | <para>Each of the new ioctls expects a pointer to a | ||
| 480 | &v4l2-ext-controls;. This structure contains a pointer to the control | ||
| 481 | array, a count of the number of controls in that array and a control | ||
| 482 | class. Control classes are used to group similar controls into a | ||
| 483 | single class. For example, control class | ||
| 484 | <constant>V4L2_CTRL_CLASS_USER</constant> contains all user controls | ||
| 485 | (&ie; all controls that can also be set using the old | ||
| 486 | <constant>VIDIOC_S_CTRL</constant> ioctl). Control class | ||
| 487 | <constant>V4L2_CTRL_CLASS_MPEG</constant> contains all controls | ||
| 488 | relating to MPEG encoding, etc.</para> | ||
| 489 | |||
| 490 | <para>All controls in the control array must belong to the | ||
| 491 | specified control class. An error is returned if this is not the | ||
| 492 | case.</para> | ||
| 493 | |||
| 494 | <para>It is also possible to use an empty control array (count | ||
| 495 | == 0) to check whether the specified control class is | ||
| 496 | supported.</para> | ||
| 497 | |||
| 498 | <para>The control array is a &v4l2-ext-control; array. The | ||
| 499 | <structname>v4l2_ext_control</structname> structure is very similar to | ||
| 500 | &v4l2-control;, except for the fact that it also allows for 64-bit | ||
| 501 | values and pointers to be passed.</para> | ||
| 502 | |||
| 503 | <para>It is important to realize that due to the flexibility of | ||
| 504 | controls it is necessary to check whether the control you want to set | ||
| 505 | actually is supported in the driver and what the valid range of values | ||
| 506 | is. So use the &VIDIOC-QUERYCTRL; and &VIDIOC-QUERYMENU; ioctls to | ||
| 507 | check this. Also note that it is possible that some of the menu | ||
| 508 | indices in a control of type <constant>V4L2_CTRL_TYPE_MENU</constant> | ||
| 509 | may not be supported (<constant>VIDIOC_QUERYMENU</constant> will | ||
| 510 | return an error). A good example is the list of supported MPEG audio | ||
| 511 | bitrates. Some drivers only support one or two bitrates, others | ||
| 512 | support a wider range.</para> | ||

| 516 | <title>Enumerating Extended Controls</title> | ||
| 517 | |||
| 518 | <para>The recommended way to enumerate over the extended | ||

| 523 | <programlisting> | ||
| 524 | &v4l2-queryctrl; qctrl; | ||

| 534 | <para>The initial control ID is set to 0 ORed with the | ||
| 535 | <constant>V4L2_CTRL_FLAG_NEXT_CTRL</constant> flag. The | ||
| 536 | <constant>VIDIOC_QUERYCTRL</constant> ioctl will return the first | ||
| 537 | control with a higher ID than the specified one. When no such controls | ||
| 538 | are found an error is returned.</para> | ||
| 539 | |||
| 540 | <para>If you want to get all controls within a specific control | ||
| 541 | class, then you can set the initial | ||
| 542 | <structfield>qctrl.id</structfield> value to the control class and add | ||
| 543 | an extra check to break out of the loop when a control of another | ||
| 544 | control class is found:</para> | ||
| 545 | |||
| 546 | <informalexample> | ||
| 547 | <programlisting> | ||
| 548 | qctrl.id = V4L2_CTRL_CLASS_MPEG | V4L2_CTRL_FLAG_NEXT_CTRL; | ||

| 557 | |||
| 558 | <para>The 32-bit <structfield>qctrl.id</structfield> value is | ||
| 559 | subdivided into three bit ranges: the top 4 bits are reserved for | ||
| 560 | flags (⪚ <constant>V4L2_CTRL_FLAG_NEXT_CTRL</constant>) and are not | ||
| 561 | actually part of the ID. The remaining 28 bits form the control ID, of | ||
| 562 | which the most significant 12 bits define the control class and the | ||
| 563 | least significant 16 bits identify the control within the control | ||
| 564 | class. It is guaranteed that these last 16 bits are always non-zero | ||
| 565 | for controls. The range of 0x1000 and up are reserved for | ||
| 566 | driver-specific controls. The macro | ||
| 567 | <constant>V4L2_CTRL_ID2CLASS(id)</constant> returns the control class | ||
| 568 | ID based on a control ID.</para> | ||
| 569 | |||
| 570 | <para>If the driver does not support extended controls, then | ||
| 571 | <constant>VIDIOC_QUERYCTRL</constant> will fail when used in | ||
| 572 | combination with <constant>V4L2_CTRL_FLAG_NEXT_CTRL</constant>. In | ||
| 573 | that case the old method of enumerating control should be used (see | ||
| 574 | 1.8). But if it is supported, then it is guaranteed to enumerate over | ||
| 575 | all controls, including driver-private controls.</para> | ||

| 581 | <para>It is possible to create control panels for a graphical | ||
| 582 | user interface where the user can select the various controls. | ||
| 583 | Basically you will have to iterate over all controls using the method | ||
| 584 | described above. Each control class starts with a control of type | ||
| 585 | <constant>V4L2_CTRL_TYPE_CTRL_CLASS</constant>. | ||
| 586 | <constant>VIDIOC_QUERYCTRL</constant> will return the name of this | ||
| 587 | control class which can be used as the title of a tab page within a | ||
| 588 | control panel.</para> | ||

| 1 | <title>Video Overlay Interface</title> | ||
| 2 | <subtitle>Also known as Framebuffer Overlay or Previewing</subtitle> | ||
| 3 | |||
| 4 | <para>Video overlay devices have the ability to genlock (TV-)video | ||
| 5 | into the (VGA-)video signal of a graphics card, or to store captured | ||
| 6 | images directly in video memory of a graphics card, typically with | ||
| 7 | clipping. This can be considerable more efficient than capturing | ||
| 8 | images and displaying them by other means. In the old days when only | ||
| 9 | nuclear power plants needed cooling towers this used to be the only | ||
| 10 | way to put live video into a window.</para> | ||
| 11 | |||
| 12 | <para>Video overlay devices are accessed through the same character | ||
| 13 | special files as <link linkend="capture">video capture</link> devices. | ||
| 14 | Note the default function of a <filename>/dev/video</filename> device | ||
| 15 | is video capturing. The overlay function is only available after | ||
| 16 | calling the &VIDIOC-S-FMT; ioctl.</para> | ||
| 17 | |||
| 18 | <para>The driver may support simultaneous overlay and capturing | ||
| 19 | using the read/write and streaming I/O methods. If so, operation at | ||
| 20 | the nominal frame rate of the video standard is not guaranteed. Frames | ||
| 21 | may be directed away from overlay to capture, or one field may be used | ||
| 22 | for overlay and the other for capture if the capture parameters permit | ||
| 23 | this.</para> | ||
| 24 | |||
| 25 | <para>Applications should use different file descriptors for | ||
| 26 | capturing and overlay. This must be supported by all drivers capable | ||
| 27 | of simultaneous capturing and overlay. Optionally these drivers may | ||
| 28 | also permit capturing and overlay with a single file descriptor for | ||
| 29 | compatibility with V4L and earlier versions of V4L2.<footnote> | ||
| 30 | <para>A common application of two file descriptors is the | ||
| 31 | XFree86 <link linkend="xvideo">Xv/V4L</link> interface driver and | ||
| 32 | a V4L2 application. While the X server controls video overlay, the | ||
| 33 | application can take advantage of memory mapping and DMA.</para> | ||
| 34 | <para>In the opinion of the designers of this API, no driver | ||
| 35 | writer taking the efforts to support simultaneous capturing and | ||
| 36 | overlay will restrict this ability by requiring a single file | ||
| 37 | descriptor, as in V4L and earlier versions of V4L2. Making this | ||
| 38 | optional means applications depending on two file descriptors need | ||
| 39 | backup routines to be compatible with all drivers, which is | ||
| 40 | considerable more work than using two fds in applications which do | ||
| 41 | not. Also two fd's fit the general concept of one file descriptor for | ||
| 42 | each logical stream. Hence as a complexity trade-off drivers | ||
| 43 | <emphasis>must</emphasis> support two file descriptors and | ||
| 44 | <emphasis>may</emphasis> support single fd operation.</para> | ||

| 72 | |||
| 73 | <para>Before overlay can commence applications must program the | ||
| 74 | driver with frame buffer parameters, namely the address and size of | ||
| 75 | the frame buffer and the image format, for example RGB 5:6:5. The | ||
| 76 | &VIDIOC-G-FBUF; and &VIDIOC-S-FBUF; ioctls are available to get | ||
| 77 | and set these parameters, respectively. The | ||
| 78 | <constant>VIDIOC_S_FBUF</constant> ioctl is privileged because it | ||
| 79 | allows to set up DMA into physical memory, bypassing the memory | ||
| 80 | protection mechanisms of the kernel. Only the superuser can change the | ||
| 81 | frame buffer address and size. Users are not supposed to run TV | ||
| 82 | applications as root or with SUID bit set. A small helper application | ||
| 83 | with suitable privileges should query the graphics system and program | ||
| 84 | the V4L2 driver at the appropriate time.</para> | ||
| 85 | |||
| 86 | <para>Some devices add the video overlay to the output signal | ||
| 87 | of the graphics card. In this case the frame buffer is not modified by | ||
| 88 | the video device, and the frame buffer address and pixel format are | ||
| 89 | not needed by the driver. The <constant>VIDIOC_S_FBUF</constant> ioctl | ||
| 90 | is not privileged. An application can check for this type of device by | ||
| 91 | calling the <constant>VIDIOC_G_FBUF</constant> ioctl.</para> | ||

| 134 | defaults. An example is given in <xref linkend="crop" />.</para> | ||
| 135 | |||
| 136 | <para>The overlay window is described by a &v4l2-window;. It | ||
| 137 | defines the size of the image, its position over the graphics surface | ||
| 138 | and the clipping to be applied. To get the current parameters | ||
| 139 | applications set the <structfield>type</structfield> field of a | ||
| 140 | &v4l2-format; to <constant>V4L2_BUF_TYPE_VIDEO_OVERLAY</constant> and | ||
| 141 | call the &VIDIOC-G-FMT; ioctl. The driver fills the | ||
| 142 | <structname>v4l2_window</structname> substructure named | ||
| 143 | <structfield>win</structfield>. It is not possible to retrieve a | ||
| 144 | previously programmed clipping list or bitmap.</para> | ||
| 145 | |||
| 146 | <para>To program the overlay window applications set the | ||
| 147 | <structfield>type</structfield> field of a &v4l2-format; to | ||

| 149 | <structfield>win</structfield> substructure and call the | ||
| 150 | &VIDIOC-S-FMT; ioctl. The driver adjusts the parameters against | ||
| 151 | hardware limits and returns the actual parameters as | ||
| 152 | <constant>VIDIOC_G_FMT</constant> does. Like | ||
| 153 | <constant>VIDIOC_S_FMT</constant>, the &VIDIOC-TRY-FMT; ioctl can be | ||
| 154 | used to learn about driver capabilities without actually changing | ||
| 155 | driver state. Unlike <constant>VIDIOC_S_FMT</constant> this also works | ||
| 156 | after the overlay has been enabled.</para> | ||
| 157 | |||
| 158 | <para>The scaling factor of the overlaid image is implied by the | ||

| 68 | written V4L2 applications should always ensure they really get what | ||
| 69 | they want, requesting reasonable parameters and then checking if the | ||
| 70 | actual parameters are suitable.</para> | ||
| 71 | |||
| 72 | <para>To query the current raw VBI capture parameters | ||
| 73 | applications set the <structfield>type</structfield> field of a | ||
| 74 | &v4l2-format; to <constant>V4L2_BUF_TYPE_VBI_CAPTURE</constant> or | ||

| 87 | an &EINVAL; only when the given parameters are ambiguous, otherwise | ||
| 88 | they modify the parameters according to the hardware capabilites and | ||
| 89 | return the actual parameters. When the driver allocates resources at | ||
| 90 | this point, it may return an &EBUSY; to indicate the returned | ||
| 91 | parameters are valid but the required resources are currently not | ||
| 92 | available. That may happen for instance when the video and VBI areas | ||
| 93 | to capture would overlap, or when the driver supports multiple opens | ||
| 94 | and another process already requested VBI capturing or output. Anyway, | ||

| 55 | hardware applications can call the &VIDIOC-G-SLICED-VBI-CAP; ioctl. | ||
| 56 | All drivers implementing the sliced VBI interface must support this | ||
| 57 | ioctl. The results may differ from those of the &VIDIOC-S-FMT; ioctl | ||
| 58 | when the number of VBI lines the hardware can capture or output per | ||
| 59 | frame, or the number of services it can identify on a given line are | ||
| 60 | limited. For example on PAL line 16 the hardware may be able to look | ||
| 61 | for a VPS or Teletext signal, but not both at the same time.</para> | ||
| 62 | |||
| 63 | <para>To determine the currently selected services applications | ||
| 64 | set the <structfield>type </structfield> field of &v4l2-format; to | ||
| 65 | <constant> V4L2_BUF_TYPE_SLICED_VBI_CAPTURE</constant> or <constant> | ||
| 66 | V4L2_BUF_TYPE_SLICED_VBI_OUTPUT</constant>, and the &VIDIOC-G-FMT; | ||
| 67 | ioctl fills the <structfield>fmt.sliced</structfield> member, a | ||
| 68 | &v4l2-sliced-vbi-format;.</para> | ||
| 69 | |||
| 70 | <para>Applications can request different parameters by | ||
| 71 | initializing or modifying the <structfield>fmt.sliced</structfield> | ||
| 72 | member and calling the &VIDIOC-S-FMT; ioctl with a pointer to the | ||
| 73 | <structname>v4l2_format</structname> structure.</para> | ||
| 74 | |||
| 75 | <para>The sliced VBI API is more complicated than the raw VBI API | ||
| 76 | because the hardware must be told which VBI service to expect on each | ||
| 77 | scan line. Not all services may be supported by the hardware on all | ||
| 78 | lines (this is especially true for VBI output where Teletext is often | ||
| 79 | unsupported and other services can only be inserted in one specific | ||
| 80 | line). In many cases, however, it is sufficient to just set the | ||
| 81 | <structfield>service_set</structfield> field to the required services | ||
| 82 | and let the driver fill the <structfield>service_lines</structfield> | ||
| 83 | array according to hardware capabilities. Only if more precise control | ||
| 84 | is needed should the programmer set the | ||
| 85 | <structfield>service_lines</structfield> array explicitly.</para> | ||
| 86 | |||
| 87 | <para>The &VIDIOC-S-FMT; ioctl modifies the parameters | ||
| 88 | according to hardware capabilities. When the driver allocates | ||
| 89 | resources at this point, it may return an &EBUSY; if the required | ||

| 447 | has already been informally specified in the kernel sources in the | ||
| 448 | file <filename>Documentation/video4linux/cx2341x/README.vbi</filename> | ||
| 449 | . The maximum size of the payload and other aspects of this format | ||
| 450 | are driven by the CX23415 MPEG decoder's capabilities and limitations | ||

| 452 | embedded within an MPEG stream.</para> | ||

| 456 | exclusive to CX2341x devices, as the sliced VBI data packet insertion | ||
| 457 | into the MPEG stream is implemented in driver software. At least the | ||
| 458 | <filename>cx18</filename> driver provides sliced VBI data insertion | ||
| 459 | into an MPEG-2 PS in this format as well.</para> | ||

| 8 | TV cards, dedicated Teletext decoding cards and home-brew devices | ||
| 9 | connected to the PC parallel port.</para> | ||
| 10 | |||
| 11 | <para>The Teletext API was designed by Martin Buck. It is defined in | ||
| 12 | the kernel header file <filename>linux/videotext.h</filename>, the | ||
| 13 | specification is available from <ulink url="ftp://ftp.gwdg.de/pub/linux/misc/videotext/"> | ||
| 14 | ftp://ftp.gwdg.de/pub/linux/misc/videotext/</ulink>. (Videotext is the name of | ||
| 15 | the German public television Teletext service.) Conventional character | ||
| 16 | device file names are <filename>/dev/vtx</filename> and | ||
| 17 | <filename>/dev/vttuner</filename>, with device number 83, 0 and 83, 16 | ||

| 20 | <filename>/dev/tlkN</filename>, device number 102, N.</para> | ||

| 24 | <filename>/dev/vtx31</filename>, device major number 81, minor numbers | ||
| 25 | 192 to 223. For reference the V4L Teletext API specification is | ||

| 33 | The purpose of this License is to make a manual, textbook, or | ||
| 34 | other written document <quote>free</quote> in the sense of | ||
| 35 | freedom: to assure everyone the effective freedom to copy and | ||
| 36 | redistribute it, with or without modifying it, either | ||
| 37 | commercially or noncommercially. Secondarily, this License | ||
| 38 | preserves for the author and publisher a way to get credit for | ||

| 40 | modifications made by others. | ||

| 44 | This License is a kind of <quote>copyleft</quote>, which means | ||
| 45 | that derivative works of the document must themselves be free in | ||
| 46 | the same sense. It complements the GNU General Public License, | ||
| 47 | which is a copyleft license designed for free software. | ||

| 50 | <para> | ||
| 51 | We have designed this License in order to use it for manuals for | ||
| 52 | free software, because free software needs free documentation: a | ||
| 53 | free program should come with manuals providing the same | ||
| 54 | freedoms that the software does. But this License is not limited | ||
| 55 | to software manuals; it can be used for any textual work, | ||
| 56 | regardless of subject matter or whether it is published as a | ||
| 57 | printed book. We recommend this License principally for works | ||
| 58 | whose purpose is instruction or reference. | ||

| 121 | formatters. A copy made in an otherwise Transparent file format | ||

| 163 | distribute. However, you may accept compensation in exchange for | ||
| 164 | copies. If you distribute a large enough number of copies you | ||

| 182 | the copies in covers that carry, clearly and legibly, all these | ||
| 183 | Cover Texts: Front-Cover Texts on the front cover, and | ||
| 184 | Back-Cover Texts on the back cover. Both covers must also | ||
| 185 | clearly and legibly identify you as the publisher of these | ||
| 186 | copies. The front cover must present the full title with all | ||
| 187 | words of the title equally prominent and visible. You may add | ||
| 188 | other material on the covers in addition. Copying with changes | ||
| 189 | limited to the covers, as long as they preserve the title of the | ||
| 190 | <link linkend="fdl-document">Document</link> and satisfy these | ||
| 191 | conditions, can be treated as verbatim copying in other | ||

| 208 | each Opaque copy, or state in or with each Opaque copy a | ||
| 209 | publicly-accessible computer-network location containing a | ||

| 211 | material, which the general network-using public has access to | ||

| 213 | protocols. If you use the latter option, you must take | ||
| 214 | reasonably prudent steps, when you begin distribution of Opaque | ||
| 215 | copies in quantity, to ensure that this Transparent copy will | ||
| 216 | remain thus accessible at the stated location until at least one | ||

| 54 | <para>The <function>ioctl()</function> function is used to program | ||
| 55 | V4L2 devices. The argument <parameter>fd</parameter> must be an open | ||
| 56 | file descriptor. An ioctl <parameter>request</parameter> has encoded | ||
| 57 | in it whether the argument is an input, output or read/write | ||
| 58 | parameter, and the size of the argument <parameter>argp</parameter> in | ||
| 59 | bytes. Macros and defines specifying V4L2 ioctl requests are located | ||
| 60 | in the <link linkend="videodev">videodev.h</link> header file. | ||
| 61 | Applications should use their own copy, not include the version in the | ||
| 62 | kernel sources on the system they compile on. All V4L2 ioctl requests, | ||
| 63 | their respective function and parameters are specified in <xref | ||

| 72 | <varname>errno</varname> variable. On failure | ||
| 73 | <returnvalue>-1</returnvalue> is returned, when the ioctl takes an | ||
| 74 | output or read/write parameter it remains unmodified, and the | ||
| 75 | <varname>errno</varname> variable is set appropriately. See below for | ||
| 76 | possible error codes. Generic errors like <errorcode>EBADF</errorcode> | ||
| 77 | or <errorcode>EFAULT</errorcode> are not listed in the sections | ||
| 78 | discussing individual ioctl requests.</para> | ||

| 34 | queue of the driver the function returns immediately.</para> | ||
| 35 | |||
| 36 | <para>On success <function>poll()</function> returns the number of | ||
| 37 | file descriptors that have been selected (that is, file descriptors | ||
| 38 | for which the <structfield>revents</structfield> field of the | ||
| 39 | respective <structname>pollfd</structname> structure is non-zero). | ||
| 40 | Capture devices set the <constant>POLLIN</constant> and | ||
| 41 | <constant>POLLRDNORM</constant> flags in the | ||
| 42 | <structfield>revents</structfield> field, output devices the | ||
| 43 | <constant>POLLOUT</constant> and <constant>POLLWRNORM</constant> | ||
| 44 | flags. When the function timed out it returns a value of zero, on | ||
| 45 | failure it returns <returnvalue>-1</returnvalue> and the | ||

| 52 | <para><function>read()</function> attempts to read up to | ||
| 53 | <parameter>count</parameter> bytes from file descriptor | ||
| 54 | <parameter>fd</parameter> into the buffer starting at | ||
| 55 | <parameter>buf</parameter>. The layout of the data in the buffer is | ||
| 56 | discussed in the respective device interface section, see ##. If <parameter>count</parameter> is zero, | ||
| 57 | <function>read()</function> returns zero and has no other results. If | ||
| 58 | <parameter>count</parameter> is greater than | ||
| 59 | <constant>SSIZE_MAX</constant>, the result is unspecified. Regardless | ||
| 60 | of the <parameter>count</parameter> value each | ||
| 61 | <function>read()</function> call will provide at most one frame (two | ||
| 62 | fields) worth of data.</para> | ||
| 63 | |||
| 64 | <para>By default <function>read()</function> blocks until data | ||
| 65 | becomes available. When the <constant>O_NONBLOCK</constant> flag was | ||
| 66 | given to the &func-open; function it | ||
| 67 | returns immediately with an &EAGAIN; when no data is available. The | ||
| 68 | &func-select; or &func-poll; functions | ||
| 69 | can always be used to suspend execution until data becomes available. All | ||
| 70 | drivers supporting the <function>read()</function> function must also | ||
| 71 | support <function>select()</function> and | ||
| 72 | <function>poll()</function>.</para> | ||
| 73 | |||
| 74 | <para>Drivers can implement read functionality in different | ||
| 75 | ways, using a single or multiple buffers and discarding the oldest or | ||
| 76 | newest frames once the internal buffers are filled.</para> | ||
| 77 | |||
| 78 | <para><function>read()</function> never returns a "snapshot" of a | ||
| 79 | buffer being filled. Using a single buffer the driver will stop | ||
| 80 | capturing when the application starts reading the buffer until the | ||
| 81 | read is finished. Thus only the period of the vertical blanking | ||
| 82 | interval is available for reading, or the capture rate must fall below | ||
| 83 | the nominal frame rate of the video standard.</para> | ||
| 84 | |||
| 85 | <para>The behavior of | ||
| 86 | <function>read()</function> when called during the active picture | ||
| 87 | period or the vertical blanking separating the top and bottom field | ||
| 88 | depends on the discarding policy. A driver discarding the oldest | ||
| 89 | frames keeps capturing into an internal buffer, continuously | ||
| 90 | overwriting the previously, not read frame, and returns the frame | ||
| 91 | being received at the time of the <function>read()</function> call as | ||
| 92 | soon as it is complete.</para> | ||
| 93 | |||
| 94 | <para>A driver discarding the newest frames stops capturing until | ||
| 95 | the next <function>read()</function> call. The frame being received at | ||
| 96 | <function>read()</function> time is discarded, returning the following | ||
| 97 | frame instead. Again this implies a reduction of the capture rate to | ||
| 98 | one half or less of the nominal frame rate. An example of this model | ||
| 99 | is the video read mode of the bttv driver, initiating a DMA to user | ||
| 100 | memory when <function>read()</function> is called and returning when | ||
| 101 | the DMA finished.</para> | ||
| 102 | |||
| 103 | <para>In the multiple buffer model drivers maintain a ring of | ||
| 104 | internal buffers, automatically advancing to the next free buffer. | ||
| 105 | This allows continuous capturing when the application can empty the | ||
| 106 | buffers fast enough. Again, the behavior when the driver runs out of | ||
| 107 | free buffers depends on the discarding policy.</para> | ||
| 108 | |||
| 109 | <para>Applications can get and set the number of buffers used | ||
| 110 | internally by the driver with the &VIDIOC-G-PARM; and &VIDIOC-S-PARM; | ||
| 111 | ioctls. They are optional, however. The discarding policy is not | ||
| 112 | reported and cannot be changed. For minimum requirements see <xref | ||
| 113 | linkend="devices" />.</para> | ||

| 117 | <title>Return Value</title> | ||
| 118 | |||
| 119 | <para>On success, the number of bytes read is returned. It is not | ||
| 120 | an error if this number is smaller than the number of bytes requested, | ||
| 121 | or the amount of data required for one frame. This may happen for | ||
| 122 | example because <function>read()</function> was interrupted by a | ||
| 123 | signal. On error, -1 is returned, and the <varname>errno</varname> | ||
| 124 | variable is set appropriately. In this case the next read will start | ||
| 125 | at the beginning of a new frame. Possible error codes are:</para> | ||

| 3 | <para>The V4L2 API defines several different methods to read from or | ||
| 4 | write to a device. All drivers exchanging data with applications must | ||
| 5 | support at least one of them.</para> | ||
| 6 | |||
| 7 | <para>The classic I/O method using the <function>read()</function> | ||
| 8 | and <function>write()</function> function is automatically selected | ||
| 9 | after opening a V4L2 device. When the driver does not support this | ||
| 10 | method attempts to read or write will fail at any time.</para> | ||
| 11 | |||
| 12 | <para>Other methods must be negotiated. To select the streaming I/O | ||
| 13 | method with memory mapped or user buffers applications call the | ||
| 14 | &VIDIOC-REQBUFS; ioctl. The asynchronous I/O method is not defined | ||
| 15 | yet.</para> | ||
| 16 | |||
| 17 | <para>Video overlay can be considered another I/O method, although | ||
| 18 | the application does not directly receive the image data. It is | ||
| 19 | selected by initiating video overlay with the &VIDIOC-S-FMT; ioctl. | ||
| 20 | For more information see <xref linkend="overlay" />.</para> | ||
| 21 | |||
| 22 | <para>Generally exactly one I/O method, including overlay, is | ||
| 23 | associated with each file descriptor. The only exceptions are | ||
| 24 | applications not exchanging data with a driver ("panel applications", | ||
| 25 | see <xref linkend="open" />) and drivers permitting simultaneous video capturing | ||
| 26 | and overlay using the same file descriptor, for compatibility with V4L | ||
| 27 | and earlier versions of V4L2.</para> | ||
| 28 | |||
| 29 | <para><constant>VIDIOC_S_FMT</constant> and | ||
| 30 | <constant>VIDIOC_REQBUFS</constant> would permit this to some degree, | ||
| 31 | but for simplicity drivers need not support switching the I/O method | ||
| 32 | (after first switching away from read/write) other than by closing | ||
| 33 | and reopening the device.</para> | ||
| 34 | |||
| 35 | <para>The following sections describe the various I/O methods in | ||
| 36 | more detail.</para> | ||

| 44 | the <structfield>capabilities</structfield> field of &v4l2-capability; | ||
| 45 | returned by the &VIDIOC-QUERYCAP; ioctl is set.</para> | ||
| 46 | |||
| 47 | <para>Drivers may need the CPU to copy the data, but they may also | ||
| 48 | support DMA to or from user memory, so this I/O method is not | ||
| 49 | necessarily less efficient than other methods merely exchanging buffer | ||
| 50 | pointers. It is considered inferior though because no meta-information | ||
| 51 | like frame counters or timestamps are passed. This information is | ||
| 52 | necessary to recognize frame dropping and to synchronize with other | ||
| 53 | data streams. However this is also the simplest I/O method, requiring | ||
| 54 | little or no setup to exchange data. It permits command line stunts | ||
| 55 | like this (the <application>vidctrl</application> tool is | ||
| 56 | fictitious):</para> | ||

| 65 | <para>To read from the device applications use the | ||
| 66 | &func-read; function, to write the &func-write; function. | ||
| 67 | Drivers must implement one I/O method if they | ||
| 68 | exchange data with applications, but it need not be this.<footnote> | ||
| 69 | <para>It would be desirable if applications could depend on | ||
| 70 | drivers supporting all I/O interfaces, but as much as the complex | ||
| 71 | memory mapping I/O can be inadequate for some devices we have no | ||
| 72 | reason to require this interface, which is most useful for simple | ||
| 73 | applications capturing still images.</para> | ||
| 74 | </footnote> When reading or writing is supported, the driver | ||
| 75 | must also support the &func-select; and &func-poll; | ||
| 76 | function.<footnote> | ||
| 77 | <para>At the driver level <function>select()</function> and | ||

| 84 | <title>Streaming I/O (Memory Mapping)</title> | ||
| 85 | |||
| 86 | <para>Input and output devices support this I/O method when the | ||
| 87 | <constant>V4L2_CAP_STREAMING</constant> flag in the | ||
| 88 | <structfield>capabilities</structfield> field of &v4l2-capability; | ||
| 89 | returned by the &VIDIOC-QUERYCAP; ioctl is set. There are two | ||
| 90 | streaming methods, to determine if the memory mapping flavor is | ||
| 91 | supported applications must call the &VIDIOC-REQBUFS; ioctl.</para> | ||
| 92 | |||
| 93 | <para>Streaming is an I/O method where only pointers to buffers | ||
| 94 | are exchanged between application and driver, the data itself is not | ||
| 95 | copied. Memory mapping is primarily intended to map buffers in device | ||
| 96 | memory into the application's address space. Device memory can be for | ||
| 97 | example the video memory on a graphics card with a video capture | ||
| 98 | add-on. However, being the most efficient I/O method available for a | ||
| 99 | long time, many other drivers support streaming as well, allocating | ||
| 100 | buffers in DMA-able main memory.</para> | ||
| 101 | |||
| 102 | <para>A driver can support many sets of buffers. Each set is | ||
| 103 | identified by a unique buffer type value. The sets are independent and | ||
| 104 | each set can hold a different type of data. To access different sets | ||
| 105 | at the same time different file descriptors must be used.<footnote> | ||
| 106 | <para>One could use one file descriptor and set the buffer | ||
| 107 | type field accordingly when calling &VIDIOC-QBUF; etc., but it makes | ||
| 108 | the <function>select()</function> function ambiguous. We also like the | ||
| 109 | clean approach of one file descriptor per logical stream. Video | ||
| 110 | overlay for example is also a logical stream, although the CPU is not | ||
| 111 | needed for continuous operation.</para> | ||
| 112 | </footnote></para> | ||
| 113 | |||
| 114 | <para>To allocate device buffers applications call the | ||
| 115 | &VIDIOC-REQBUFS; ioctl with the desired number of buffers and buffer | ||
| 116 | type, for example <constant>V4L2_BUF_TYPE_VIDEO_CAPTURE</constant>. | ||
| 117 | This ioctl can also be used to change the number of buffers or to free | ||
| 118 | the allocated memory, provided none of the buffers are still | ||
| 119 | mapped.</para> | ||
| 120 | |||
| 121 | <para>Before applications can access the buffers they must map | ||
| 122 | them into their address space with the &func-mmap; function. The | ||
| 123 | location of the buffers in device memory can be determined with the | ||
| 124 | &VIDIOC-QUERYBUF; ioctl. The <structfield>m.offset</structfield> and | ||
| 125 | <structfield>length</structfield> returned in a &v4l2-buffer; are | ||
| 126 | passed as sixth and second parameter to the | ||
| 127 | <function>mmap()</function> function. The offset and length values | ||
| 128 | must not be modified. Remember the buffers are allocated in physical | ||
| 129 | memory, as opposed to virtual memory which can be swapped out to disk. | ||
| 130 | Applications should free the buffers as soon as possible with the | ||
| 131 | &func-munmap; function.</para> | ||

| 204 | <para>Conceptually streaming drivers maintain two buffer queues, an incoming | ||
| 205 | and an outgoing queue. They separate the synchronous capture or output | ||
| 206 | operation locked to a video clock from the application which is | ||
| 207 | subject to random disk or network delays and preemption by | ||
| 208 | other processes, thereby reducing the probability of data loss. | ||
| 209 | The queues are organized as FIFOs, buffers will be | ||
| 210 | output in the order enqueued in the incoming FIFO, and were | ||
| 211 | captured in the order dequeued from the outgoing FIFO.</para> | ||
| 212 | |||
| 213 | <para>The driver may require a minimum number of buffers enqueued | ||
| 214 | at all times to function, apart of this no limit exists on the number | ||
| 215 | of buffers applications can enqueue in advance, or dequeue and | ||
| 216 | process. They can also enqueue in a different order than buffers have | ||
| 217 | been dequeued, and the driver can <emphasis>fill</emphasis> enqueued | ||
| 218 | <emphasis>empty</emphasis> buffers in any order. <footnote> | ||
| 219 | <para>Random enqueue order permits applications processing | ||
| 220 | images out of order (such as video codecs) to return buffers earlier, | ||
| 221 | reducing the probability of data loss. Random fill order allows | ||
| 222 | drivers to reuse buffers on a LIFO-basis, taking advantage of caches | ||
| 223 | holding scatter-gather lists and the like.</para> | ||
| 224 | </footnote> The index number of a buffer (&v4l2-buffer; | ||
| 225 | <structfield>index</structfield>) plays no role here, it only | ||
| 226 | identifies the buffer.</para> | ||
| 227 | |||
| 228 | <para>Initially all mapped buffers are in dequeued state, | ||
| 229 | inaccessible by the driver. For capturing applications it is customary | ||
| 230 | to first enqueue all mapped buffers, then to start capturing and enter | ||
| 231 | the read loop. Here the application waits until a filled buffer can be | ||
| 232 | dequeued, and re-enqueues the buffer when the data is no longer | ||
| 233 | needed. Output applications fill and enqueue buffers, when enough | ||
| 234 | buffers are stacked up the output is started with | ||
| 235 | <constant>VIDIOC_STREAMON</constant>. In the write loop, when | ||
| 236 | the application runs out of free buffers, it must wait until an empty | ||
| 237 | buffer can be dequeued and reused.</para> | ||
| 238 | |||
| 239 | <para>To enqueue and dequeue a buffer applications use the | ||
| 240 | &VIDIOC-QBUF; and &VIDIOC-DQBUF; ioctl. The status of a buffer being | ||
| 241 | mapped, enqueued, full or empty can be determined at any time using the | ||
| 242 | &VIDIOC-QUERYBUF; ioctl. Two methods exist to suspend execution of the | ||
| 243 | application until one or more buffers can be dequeued. By default | ||
| 244 | <constant>VIDIOC_DQBUF</constant> blocks when no buffer is in the | ||
| 245 | outgoing queue. When the <constant>O_NONBLOCK</constant> flag was | ||
| 246 | given to the &func-open; function, <constant>VIDIOC_DQBUF</constant> | ||
| 247 | returns immediately with an &EAGAIN; when no buffer is available. The | ||
| 248 | &func-select; or &func-poll; function are always available.</para> | ||
| 249 | |||
| 250 | <para>To start and stop capturing or output applications call the | ||
| 251 | &VIDIOC-STREAMON; and &VIDIOC-STREAMOFF; ioctl. Note | ||
| 252 | <constant>VIDIOC_STREAMOFF</constant> removes all buffers from both | ||
| 253 | queues as a side effect. Since there is no notion of doing anything | ||
| 254 | "now" on a multitasking system, if an application needs to synchronize | ||
| 255 | with another event it should examine the &v4l2-buffer; | ||
| 256 | <structfield>timestamp</structfield> of captured buffers, or set the | ||
| 257 | field before enqueuing buffers for output.</para> | ||

| 287 | |||
| 288 | <para>This I/O method combines advantages of the read/write and | ||
| 289 | memory mapping methods. Buffers are allocated by the application | ||
| 290 | itself, and can reside for example in virtual or shared memory. Only | ||
| 291 | pointers to data are exchanged, these pointers and meta-information | ||
| 292 | are passed in &v4l2-buffer;. The driver must be switched | ||
| 293 | into user pointer I/O mode by calling the &VIDIOC-REQBUFS; with the | ||
| 294 | desired buffer type. No buffers are allocated beforehands, | ||
| 295 | consequently they are not indexed and cannot be queried like mapped | ||
| 296 | buffers with the <constant>VIDIOC_QUERYBUF</constant> ioctl.</para> | ||

| 319 | <para>Buffer addresses and sizes are passed on the fly with the | ||
| 320 | &VIDIOC-QBUF; ioctl. Although buffers are commonly cycled, | ||
| 321 | applications can pass different addresses and sizes at each | ||
| 322 | <constant>VIDIOC_QBUF</constant> call. If required by the hardware the | ||
| 323 | driver swaps memory pages within physical memory to create a | ||
| 324 | continuous area of memory. This happens transparently to the | ||
| 325 | application in the virtual memory subsystem of the kernel. When buffer | ||
| 326 | pages have been swapped out to disk they are brought back and finally | ||
| 327 | locked in physical memory for DMA.<footnote> | ||
| 328 | <para>We expect that frequently used buffers are typically not | ||
| 329 | swapped out. Anyway, the process of swapping, locking or generating | ||
| 330 | scatter-gather lists may be time consuming. The delay can be masked by | ||
| 331 | the depth of the incoming buffer queue, and perhaps by maintaining | ||
| 332 | caches assuming a buffer will be soon enqueued again. On the other | ||
| 333 | hand, to optimize memory usage drivers can limit the number of buffers | ||
| 334 | locked in advance and recycle the most recently used buffers first. Of | ||
| 335 | course, the pages of empty buffers in the incoming queue need not be | ||
| 336 | saved to disk. Output buffers must be saved on the incoming and | ||
| 337 | outgoing queue because an application may share them with other | ||
| 338 | processes.</para> | ||
| 339 | </footnote></para> | ||
| 340 | |||
| 341 | <para>Filled or displayed buffers are dequeued with the | ||
| 342 | &VIDIOC-DQBUF; ioctl. The driver can unlock the memory pages at any | ||
| 343 | time between the completion of the DMA and this ioctl. The memory is | ||
| 344 | also unlocked when &VIDIOC-STREAMOFF; is called, &VIDIOC-REQBUFS;, or | ||
| 345 | when the device is closed. Applications must take care not to free | ||
| 346 | buffers without dequeuing. For once, the buffers remain locked until | ||
| 347 | further, wasting physical memory. Second the driver will not be | ||
| 348 | notified when the memory is returned to the application's free list | ||
| 349 | and subsequently reused for other purposes, possibly completing the | ||
| 350 | requested DMA and overwriting valuable data.</para> | ||
| 351 | |||
| 352 | <para>For capturing applications it is customary to enqueue a | ||
| 353 | number of empty buffers, to start capturing and enter the read loop. | ||
| 354 | Here the application waits until a filled buffer can be dequeued, and | ||
| 355 | re-enqueues the buffer when the data is no longer needed. Output | ||
| 356 | applications fill and enqueue buffers, when enough buffers are stacked | ||
| 357 | up output is started. In the write loop, when the application | ||
| 358 | runs out of free buffers it must wait until an empty buffer can be | ||
| 359 | dequeued and reused. Two methods exist to suspend execution of the | ||
| 360 | application until one or more buffers can be dequeued. By default | ||
| 361 | <constant>VIDIOC_DQBUF</constant> blocks when no buffer is in the | ||
| 362 | outgoing queue. When the <constant>O_NONBLOCK</constant> flag was | ||
| 363 | given to the &func-open; function, <constant>VIDIOC_DQBUF</constant> | ||
| 364 | returns immediately with an &EAGAIN; when no buffer is available. The | ||
| 365 | &func-select; or &func-poll; function are always available.</para> | ||
| 366 | |||
| 367 | <para>To start and stop capturing or output applications call the | ||
| 368 | &VIDIOC-STREAMON; and &VIDIOC-STREAMOFF; ioctl. Note | ||
| 369 | <constant>VIDIOC_STREAMOFF</constant> removes all buffers from both | ||
| 370 | queues and unlocks all buffers as a side effect. Since there is no | ||
| 371 | notion of doing anything "now" on a multitasking system, if an | ||
| 372 | application needs to synchronize with another event it should examine | ||
| 373 | the &v4l2-buffer; <structfield>timestamp</structfield> of captured | ||
| 374 | buffers, or set the field before enqueuing buffers for output.</para> | ||

| 398 | <para>A buffer contains data exchanged by application and | ||
| 399 | driver using one of the Streaming I/O methods. Only pointers to | ||
| 400 | buffers are exchanged, the data itself is not copied. These pointers, | ||
| 401 | together with meta-information like timestamps or field parity, are | ||
| 402 | stored in a struct <structname>v4l2_buffer</structname>, argument to | ||
| 403 | the &VIDIOC-QUERYBUF;, &VIDIOC-QBUF; and &VIDIOC-DQBUF; ioctl.</para> | ||
| 404 | |||
| 405 | <para>Nominally timestamps refer to the first data byte transmitted. | ||
| 406 | In practice however the wide range of hardware covered by the V4L2 API | ||
| 407 | limits timestamp accuracy. Often an interrupt routine will | ||
| 408 | sample the system clock shortly after the field or frame was stored | ||
| 409 | completely in memory. So applications must expect a constant | ||
| 410 | difference up to one field or frame period plus a small (few scan | ||
| 411 | lines) random error. The delay and error can be much | ||
| 412 | larger due to compression or transmission over an external bus when | ||
| 413 | the frames are not properly stamped by the sender. This is frequently | ||
| 414 | the case with USB cameras. Here timestamps refer to the instant the | ||
| 415 | field or frame was received by the driver, not the capture time. These | ||
| 416 | devices identify by not enumerating any video standards, see <xref | ||
| 417 | linkend="standard" />.</para> | ||
| 418 | |||
| 419 | <para>Similar limitations apply to output timestamps. Typically | ||
| 420 | the video hardware locks to a clock controlling the video timing, the | ||
| 421 | horizontal and vertical synchronization pulses. At some point in the | ||
| 422 | line sequence, possibly the vertical blanking, an interrupt routine | ||
| 423 | samples the system clock, compares against the timestamp and programs | ||
| 424 | the hardware to repeat the previous field or frame, or to display the | ||
| 425 | buffer contents.</para> | ||
| 426 | |||
| 427 | <para>Apart of limitations of the video device and natural | ||
| 428 | inaccuracies of all clocks, it should be noted system time itself is | ||
| 429 | not perfectly stable. It can be affected by power saving cycles, | ||
| 430 | warped to insert leap seconds, or even turned back or forth by the | ||
| 431 | system administrator affecting long term measurements. <footnote> | ||
| 432 | <para>Since no other Linux multimedia | ||
| 433 | API supports unadjusted time it would be foolish to introduce here. We | ||
| 434 | must use a universally supported clock to synchronize different media, | ||
| 435 | hence time of day.</para> | ||

| 896 | <title>Field Order</title> | ||
| 897 | |||
| 898 | <para>We have to distinguish between progressive and interlaced | ||
| 899 | video. Progressive video transmits all lines of a video image | ||
| 900 | sequentially. Interlaced video divides an image into two fields, | ||
| 901 | containing only the odd and even lines of the image, respectively. | ||
| 902 | Alternating the so called odd and even field are transmitted, and due | ||
| 903 | to a small delay between fields a cathode ray TV displays the lines | ||
| 904 | interleaved, yielding the original frame. This curious technique was | ||
| 905 | invented because at refresh rates similar to film the image would | ||
| 906 | fade out too quickly. Transmitting fields reduces the flicker without | ||
| 907 | the necessity of doubling the frame rate and with it the bandwidth | ||
| 908 | required for each channel.</para> | ||
| 909 | |||
| 910 | <para>It is important to understand a video camera does not expose | ||
| 911 | one frame at a time, merely transmitting the frames separated into | ||
| 912 | fields. The fields are in fact captured at two different instances in | ||
| 913 | time. An object on screen may well move between one field and the | ||
| 914 | next. For applications analysing motion it is of paramount importance | ||
| 915 | to recognize which field of a frame is older, the <emphasis>temporal | ||
| 916 | order</emphasis>.</para> | ||
| 917 | |||
| 918 | <para>When the driver provides or accepts images field by field | ||
| 919 | rather than interleaved, it is also important applications understand | ||
| 920 | how the fields combine to frames. We distinguish between top and | ||
| 921 | bottom fields, the <emphasis>spatial order</emphasis>: The first line | ||
| 922 | of the top field is the first line of an interlaced frame, the first | ||
| 923 | line of the bottom field is the second line of that frame.</para> | ||
| 924 | |||
| 925 | <para>However because fields were captured one after the other, | ||
| 926 | arguing whether a frame commences with the top or bottom field is | ||
| 927 | pointless. Any two successive top and bottom, or bottom and top fields | ||
| 928 | yield a valid frame. Only when the source was progressive to begin | ||
| 929 | with, ⪚ when transferring film to video, two fields may come from | ||
| 930 | the same frame, creating a natural order.</para> | ||
| 931 | |||
| 932 | <para>Counter to intuition the top field is not necessarily the | ||
| 933 | older field. Whether the older field contains the top or bottom lines | ||
| 934 | is a convention determined by the video standard. Hence the | ||
| 935 | distinction between temporal and spatial order of fields. The diagrams | ||
| 936 | below should make this clearer.</para> | ||
| 937 | |||
| 938 | <para>All video capture and output devices must report the current | ||
| 939 | field order. Some drivers may permit the selection of a different | ||
| 940 | order, to this end applications initialize the | ||
| 941 | <structfield>field</structfield> field of &v4l2-pix-format; before | ||
| 942 | calling the &VIDIOC-S-FMT; ioctl. If this is not desired it should | ||

| 49 | <para>Later on libv4lconvert was expanded to also be able to do | ||
| 50 | various video processing functions to improve webcam video quality. | ||
| 51 | The video processing is split in to 2 parts: libv4lconvert/control and | ||
| 52 | libv4lconvert/processing.</para> | ||
| 53 | |||
| 54 | <para>The control part is used to offer video controls which can | ||
| 55 | be used to control the video processing functions made available by | ||
| 56 | libv4lconvert/processing. These controls are stored application wide | ||
| 57 | (until reboot) by using a persistent shared memory object.</para> | ||

| 63 | <title>libv4l1</title> | ||
| 64 | <para>This library offers functions that can be used to quickly | ||
| 65 | make v4l1 applications work with v4l2 devices. These functions work exactly | ||
| 66 | like the normal open/close/etc, except that libv4l1 does full emulation of | ||
| 67 | the v4l1 api on top of v4l2 drivers, in case of v4l1 drivers it | ||
| 68 | will just pass calls through.</para> | ||
| 69 | <para>Since those functions are emulations of the old V4L1 API, | ||
| 70 | it shouldn't be used for new applications.</para> | ||
| 71 | </section> | ||
| 72 | <section> | ||
| 73 | <title>libv4l2</title> | ||
| 74 | <para>This library should be used for all modern V4L2 | ||
| 75 | applications.</para> | ||
| 76 | <para>It provides handles to call V4L2 open/ioctl/close/poll | ||
| 77 | methods. Instead of just providing the raw output of the device, it enhances | ||
| 78 | the calls in the sense that it will use libv4lconvert to provide more video | ||
| 79 | formats and to enhance the image quality.</para> | ||
| 80 | <para>In most cases, libv4l2 just passes the calls directly | ||
| 81 | through to the v4l2 driver, intercepting the calls to | ||

| 15 | <para>This format is not commonly used. This is a planar | ||
| 16 | version of the YUYV format. The three components are separated into | ||
| 17 | three sub-images or planes. The Y plane is first. The Y plane has one | ||
| 18 | byte per pixel. The Cb plane immediately follows the Y plane in | ||
| 19 | memory. The Cb plane is half the width of the Y plane (and of the | ||
| 20 | image). Each Cb belongs to two pixels. For example, | ||
| 21 | Cb<subscript>0</subscript> belongs to Y'<subscript>00</subscript>, | ||
| 22 | Y'<subscript>01</subscript>. Following the Cb plane is the Cr plane, | ||
| 23 | just like the Cb plane.</para> | ||
| 24 | |||
| 25 | <para>If the Y plane has pad bytes after each row, then the Cr | ||
| 26 | and Cb planes have half as many pad bytes after their rows. In other | ||
| 27 | words, two Cx rows (including padding) is exactly as long as one Y row | ||
| 28 | (including padding).</para> | ||

| 111 | <title>Standard Image Formats</title> | ||
| 112 | |||
| 113 | <para>In order to exchange images between drivers and | ||
| 114 | applications, it is necessary to have standard image data formats | ||
| 115 | which both sides will interpret the same way. V4L2 includes several | ||
| 116 | such formats, and this section is intended to be an unambiguous | ||
| 117 | specification of the standard image data formats in V4L2.</para> | ||
| 118 | |||
| 119 | <para>V4L2 drivers are not limited to these formats, however. | ||
| 120 | Driver-specific formats are possible. In that case the application may | ||
| 121 | depend on a codec to convert images to one of the standard formats | ||
| 122 | when needed. But the data can still be stored and retrieved in the | ||
| 123 | proprietary format. For example, a device may support a proprietary | ||
| 124 | compressed format. Applications can still capture and save the data in | ||
| 125 | the compressed format, saving much disk space, and later use a codec | ||
| 126 | to convert the images to the X Windows screen format when the video is | ||
| 127 | to be displayed.</para> | ||
| 128 | |||
| 129 | <para>Even so, ultimately, some standard formats are needed, so | ||
| 130 | the V4L2 specification would not be complete without well-defined | ||
| 131 | standard formats.</para> | ||
| 132 | |||
| 133 | <para>The V4L2 standard formats are mainly uncompressed formats. The | ||
| 134 | pixels are always arranged in memory from left to right, and from top | ||
| 135 | to bottom. The first byte of data in the image buffer is always for | ||
| 136 | the leftmost pixel of the topmost row. Following that is the pixel | ||
| 137 | immediately to its right, and so on until the end of the top row of | ||
| 138 | pixels. Following the rightmost pixel of the row there may be zero or | ||
| 139 | more bytes of padding to guarantee that each row of pixel data has a | ||
| 140 | certain alignment. Following the pad bytes, if any, is data for the | ||
| 141 | leftmost pixel of the second row from the top, and so on. The last row | ||
| 142 | has just as many pad bytes after it as the other rows.</para> | ||
| 143 | |||
| 144 | <para>In V4L2 each format has an identifier which looks like | ||
| 145 | <constant>PIX_FMT_XXX</constant>, defined in the <link | ||
| 146 | linkend="videodev">videodev.h</link> header file. These identifiers | ||
| 147 | represent <link linkend="v4l2-fourcc">four character codes</link> | ||
| 148 | which are also listed below, however they are not the same as those | ||
| 149 | used in the Windows world.</para> | ||

| 573 | <title>YUV Formats</title> | ||
| 574 | |||
| 575 | <para>YUV is the format native to TV broadcast and composite video | ||
| 576 | signals. It separates the brightness information (Y) from the color | ||
| 577 | information (U and V or Cb and Cr). The color information consists of | ||
| 578 | red and blue <emphasis>color difference</emphasis> signals, this way | ||
| 579 | the green component can be reconstructed by subtracting from the | ||
| 580 | brightness component. See <xref linkend="colorspaces" /> for conversion | ||
| 581 | examples. YUV was chosen because early television would only transmit | ||
| 582 | brightness information. To add color in a way compatible with existing | ||
| 583 | receivers a new signal carrier was added to transmit the color | ||
| 584 | difference signals. Secondary in the YUV format the U and V components | ||
| 585 | usually have lower resolution than the Y component. This is an analog | ||
| 586 | video compression technique taking advantage of a property of the | ||
| 587 | human visual system, being more sensitive to brightness | ||
| 588 | information.</para> | ||

| 5 | <para>Currently, most analog and digital devices have a Infrared input for remote controllers. Each | ||
| 6 | manufacturer has their own type of control. It is not rare for the same manufacturer to ship different | ||
| 7 | types of controls, depending on the device.</para> | ||
| 8 | <para>Unfortunately, for several years, there was no effort to create uniform IR keycodes for | ||
| 9 | different devices. This caused the same IR keyname to be mapped completely differently on | ||
| 10 | different IR devices. This resulted that the same IR keyname to be mapped completely different on | ||
| 11 | different IR's. Due to that, V4L2 API now specifies a standard for mapping Media keys on IR.</para> | ||
| 12 | <para>This standard should be used by both V4L/DVB drivers and userspace applications</para> | ||
| 13 | <para>The modules register the remote as keyboard within the linux input layer. This means that the IR key strokes will look like normal keyboard key strokes (if CONFIG_INPUT_KEYBOARD is enabled). Using the event devices (CONFIG_INPUT_EVDEV) it is possible for applications to access the remote via /dev/input/event devices.</para> | ||

| 60 | <para>For driver debugging purposes this ioctl allows test | ||

| 69 | fields of a &v4l2-dbg-chip-ident; | ||
| 70 | and call <constant>VIDIOC_DBG_G_CHIP_IDENT</constant> with a pointer to | ||
| 71 | this structure. On success the driver stores information about the | ||

| 65 | interface and may change in the future.</para> | ||
| 66 | </note> | ||
| 67 | |||
| 68 | <para>For driver debugging purposes these ioctls allow test | ||
| 69 | applications to access hardware registers directly. Regular | ||
| 70 | applications must not use them.</para> | ||
| 71 | |||
| 72 | <para>Since writing or even reading registers can jeopardize the | ||
| 73 | system security, its stability and damage the hardware, both ioctls | ||
| 74 | require superuser privileges. Additionally the Linux kernel must be | ||
| 75 | compiled with the <constant>CONFIG_VIDEO_ADV_DEBUG</constant> option | ||
| 76 | to enable these ioctls.</para> | ||
| 77 | |||
| 78 | <para>To write a register applications must initialize all fields | ||
| 79 | of a &v4l2-dbg-register; and call | ||
| 80 | <constant>VIDIOC_DBG_S_REGISTER</constant> with a pointer to this | ||
| 81 | structure. The <structfield>match.type</structfield> and | ||
| 82 | <structfield>match.addr</structfield> or <structfield>match.name</structfield> | ||
| 83 | fields select a chip on the TV | ||
| 84 | card, the <structfield>reg</structfield> field specifies a register | ||
| 85 | number and the <structfield>val</structfield> field the value to be | ||
| 86 | written into the register.</para> | ||
| 87 | |||
| 88 | <para>To read a register applications must initialize the | ||
| 89 | <structfield>match.type</structfield>, | ||
| 90 | <structfield>match.chip</structfield> or <structfield>match.name</structfield> and | ||
| 91 | <structfield>reg</structfield> fields, and call | ||
| 92 | <constant>VIDIOC_DBG_G_REGISTER</constant> with a pointer to this | ||
| 93 | structure. On success the driver stores the register value in the | ||
| 94 | <structfield>val</structfield> field. On failure the structure remains | ||
| 95 | unchanged.</para> | ||
| 96 | |||
| 97 | <para>When <structfield>match.type</structfield> is | ||
| 98 | <constant>V4L2_CHIP_MATCH_HOST</constant>, | ||
| 99 | <structfield>match.addr</structfield> selects the nth non-&i2c; chip | ||
| 100 | on the TV card. The number zero always selects the host chip, ⪚ the | ||
| 101 | chip connected to the PCI or USB bus. You can find out which chips are | ||
| 102 | present with the &VIDIOC-DBG-G-CHIP-IDENT; ioctl.</para> | ||
| 103 | |||
| 104 | <para>When <structfield>match.type</structfield> is | ||
| 105 | <constant>V4L2_CHIP_MATCH_I2C_DRIVER</constant>, | ||
| 106 | <structfield>match.name</structfield> contains the I2C driver name. | ||
| 107 | For instance | ||
| 108 | <constant>"saa7127"</constant> will match any chip | ||
| 109 | supported by the saa7127 driver, regardless of its &i2c; bus address. | ||
| 110 | When multiple chips supported by the same driver are present, the | ||
| 111 | effect of these ioctls is undefined. Again with the | ||
| 112 | &VIDIOC-DBG-G-CHIP-IDENT; ioctl you can find out which &i2c; chips are | ||
| 113 | present.</para> | ||
| 114 | |||
| 115 | <para>When <structfield>match.type</structfield> is | ||
| 116 | <constant>V4L2_CHIP_MATCH_I2C_ADDR</constant>, | ||
| 117 | <structfield>match.addr</structfield> selects a chip by its 7 bit &i2c; | ||
| 118 | bus address.</para> | ||
| 119 | |||
| 120 | <para>When <structfield>match.type</structfield> is | ||
| 121 | <constant>V4L2_CHIP_MATCH_AC97</constant>, | ||
| 122 | <structfield>match.addr</structfield> selects the nth AC97 chip | ||
| 123 | on the TV card.</para> | ||
| 124 | |||
| 125 | <note> | ||
| 126 | <title>Success not guaranteed</title> | ||
| 127 | |||
| 128 | <para>Due to a flaw in the Linux &i2c; bus driver these ioctls may | ||
| 129 | return successfully without actually reading or writing a register. To | ||
| 130 | catch the most likely failure we recommend a &VIDIOC-DBG-G-CHIP-IDENT; | ||
| 131 | call confirming the presence of the selected &i2c; chip.</para> | ||
| 132 | </note> | ||
| 133 | |||
| 134 | <para>These ioctls are optional, not all drivers may support them. | ||
| 135 | However when a driver supports these ioctls it must also support | ||
| 136 | &VIDIOC-DBG-G-CHIP-IDENT;. Conversely it may support | ||
| 137 | <constant>VIDIOC_DBG_G_CHIP_IDENT</constant> but not these ioctls.</para> | ||
| 138 | |||
| 139 | <para><constant>VIDIOC_DBG_G_REGISTER</constant> and | ||

| 58 | |||
| 59 | <para>These ioctls control an audio/video (usually MPEG-) encoder. | ||
| 60 | <constant>VIDIOC_ENCODER_CMD</constant> sends a command to the | ||
| 61 | encoder, <constant>VIDIOC_TRY_ENCODER_CMD</constant> can be used to | ||
| 62 | try a command without actually executing it.</para> | ||
| 63 | |||
| 64 | <para>To send a command applications must initialize all fields of a | ||
| 65 | &v4l2-encoder-cmd; and call | ||
| 66 | <constant>VIDIOC_ENCODER_CMD</constant> or | ||
| 67 | <constant>VIDIOC_TRY_ENCODER_CMD</constant> with a pointer to this | ||
| 68 | structure.</para> | ||
| 69 | |||
| 70 | <para>The <structfield>cmd</structfield> field must contain the | ||
| 71 | command code. The <structfield>flags</structfield> field is currently | ||
| 72 | only used by the STOP command and contains one bit: If the | ||
| 73 | <constant>V4L2_ENC_CMD_STOP_AT_GOP_END</constant> flag is set, | ||
| 74 | encoding will continue until the end of the current <wordasword>Group | ||
| 75 | Of Pictures</wordasword>, otherwise it will stop immediately.</para> | ||
| 76 | |||
| 77 | <para>A <function>read</function>() call sends a START command to | ||
| 78 | the encoder if it has not been started yet. After a STOP command, | ||
| 79 | <function>read</function>() calls will read the remaining data | ||
| 80 | buffered by the driver. When the buffer is empty, | ||
| 81 | <function>read</function>() will return zero and the next | ||
| 82 | <function>read</function>() call will restart the encoder.</para> | ||
| 83 | |||
| 84 | <para>A <function>close</function>() call sends an immediate STOP | ||
| 85 | to the encoder, and all buffered data is discarded.</para> | ||
| 86 | |||
| 87 | <para>These ioctls are optional, not all drivers may support | ||
| 88 | them. They were introduced in Linux 2.6.21.</para> | ||

| 53 | <para>This ioctl allows applications to enumerate all frame | ||
| 54 | intervals that the device supports for the given pixel format and | ||
| 55 | frame size.</para> | ||
| 56 | <para>The supported pixel formats and frame sizes can be obtained | ||
| 57 | by using the &VIDIOC-ENUM-FMT; and &VIDIOC-ENUM-FRAMESIZES; | ||
| 58 | functions.</para> | ||
| 59 | <para>The return value and the content of the | ||
| 60 | <structfield>v4l2_frmivalenum.type</structfield> field depend on the | ||
| 61 | type of frame intervals the device supports. Here are the semantics of | ||
| 62 | the function for the different cases:</para> | ||

| 65 | <para><emphasis role="bold">Discrete:</emphasis> The function | ||
| 66 | returns success if the given index value (zero-based) is valid. The | ||
| 67 | application should increase the index by one for each call until | ||
| 68 | <constant>EINVAL</constant> is returned. The `v4l2_frmivalenum.type` | ||
| 69 | field is set to `V4L2_FRMIVAL_TYPE_DISCRETE` by the driver. Of the | ||
| 70 | union only the `discrete` member is valid.</para> | ||
| 71 | </listitem> | ||
| 72 | <listitem> | ||
| 73 | <para><emphasis role="bold">Step-wise:</emphasis> The function | ||
| 74 | returns success if the given index value is zero and | ||
| 75 | <constant>EINVAL</constant> for any other index value. The | ||
| 76 | <structfield>v4l2_frmivalenum.type</structfield> field is set to | ||
| 77 | <constant>V4L2_FRMIVAL_TYPE_STEPWISE</constant> by the driver. Of the | ||
| 78 | union only the <structfield>stepwise</structfield> member is | ||

| 86 | <structfield>v4l2_frmivalenum.type</structfield> field is set to | ||

| 97 | sense to increase the index value to receive more frame | ||
| 98 | intervals.</para> | ||
| 99 | <para>Note that the order in which the frame intervals are | ||
| 100 | returned has no special meaning. In particular does it not say | ||
| 101 | anything about potential default frame intervals.</para> | ||
| 102 | <para>Applications can assume that the enumeration data does not | ||
| 103 | change without any interaction from the application itself. This means | ||
| 104 | that the enumeration data is consistent if the application does not | ||

| 58 | <para>The <constant>VIDIOC_G_ENC_INDEX</constant> ioctl provides | ||
| 59 | meta data about a compressed video stream the same or another | ||
| 60 | application currently reads from the driver, which is useful for | ||
| 61 | random access into the stream without decoding it.</para> | ||
| 62 | |||
| 63 | <para>To read the data applications must call | ||
| 64 | <constant>VIDIOC_G_ENC_INDEX</constant> with a pointer to a | ||
| 65 | &v4l2-enc-idx;. On success the driver fills the | ||
| 66 | <structfield>entry</structfield> array, stores the number of elements | ||
| 67 | written in the <structfield>entries</structfield> field, and | ||
| 68 | initializes the <structfield>entries_cap</structfield> field.</para> | ||
| 69 | |||
| 70 | <para>Each element of the <structfield>entry</structfield> array | ||
| 71 | contains meta data about one picture. A | ||
| 72 | <constant>VIDIOC_G_ENC_INDEX</constant> call reads up to | ||
| 73 | <constant>V4L2_ENC_IDX_ENTRIES</constant> entries from a driver | ||
| 74 | buffer, which can hold up to <structfield>entries_cap</structfield> | ||
| 75 | entries. This number can be lower or higher than | ||
| 76 | <constant>V4L2_ENC_IDX_ENTRIES</constant>, but not zero. When the | ||
| 77 | application fails to read the meta data in time the oldest entries | ||
| 78 | will be lost. When the buffer is empty or no capturing/encoding is in | ||
| 79 | progress, <structfield>entries</structfield> will be zero.</para> | ||

| 57 | <para>These ioctls allow the caller to get or set multiple | ||
| 58 | controls atomically. Control IDs are grouped into control classes (see | ||
| 59 | <xref linkend="ctrl-class" />) and all controls in the control array | ||
| 60 | must belong to the same control class.</para> | ||
| 61 | |||
| 62 | <para>Applications must always fill in the | ||
| 63 | <structfield>count</structfield>, | ||
| 64 | <structfield>ctrl_class</structfield>, | ||
| 65 | <structfield>controls</structfield> and | ||
| 66 | <structfield>reserved</structfield> fields of &v4l2-ext-controls;, and | ||
| 67 | initialize the &v4l2-ext-control; array pointed to by the | ||
| 68 | <structfield>controls</structfield> fields.</para> | ||
| 69 | |||
| 70 | <para>To get the current value of a set of controls applications | ||
| 71 | initialize the <structfield>id</structfield>, | ||
| 72 | <structfield>size</structfield> and <structfield>reserved2</structfield> fields | ||
| 73 | of each &v4l2-ext-control; and call the | ||
| 74 | <constant>VIDIOC_G_EXT_CTRLS</constant> ioctl. String controls controls | ||
| 75 | must also set the <structfield>string</structfield> field.</para> | ||
| 76 | |||
| 77 | <para>If the <structfield>size</structfield> is too small to | ||
| 78 | receive the control result (only relevant for pointer-type controls | ||
| 79 | like strings), then the driver will set <structfield>size</structfield> | ||
| 80 | to a valid value and return an &ENOSPC;. You should re-allocate the | ||
| 81 | string memory to this new size and try again. It is possible that the | ||
| 82 | same issue occurs again if the string has grown in the meantime. It is | ||
| 83 | recommended to call &VIDIOC-QUERYCTRL; first and use | ||
| 84 | <structfield>maximum</structfield>+1 as the new <structfield>size</structfield> | ||
| 85 | value. It is guaranteed that that is sufficient memory. | ||
| 86 | </para> | ||
| 87 | |||
| 88 | <para>To change the value of a set of controls applications | ||
| 89 | initialize the <structfield>id</structfield>, <structfield>size</structfield>, | ||
| 90 | <structfield>reserved2</structfield> and | ||
| 91 | <structfield>value/string</structfield> fields of each &v4l2-ext-control; and | ||
| 92 | call the <constant>VIDIOC_S_EXT_CTRLS</constant> ioctl. The controls | ||
| 93 | will only be set if <emphasis>all</emphasis> control values are | ||
| 94 | valid.</para> | ||
| 95 | |||
| 96 | <para>To check if a set of controls have correct values applications | ||
| 97 | initialize the <structfield>id</structfield>, <structfield>size</structfield>, | ||
| 98 | <structfield>reserved2</structfield> and | ||
| 99 | <structfield>value/string</structfield> fields of each &v4l2-ext-control; and | ||
| 100 | call the <constant>VIDIOC_TRY_EXT_CTRLS</constant> ioctl. It is up to | ||
| 101 | the driver whether wrong values are automatically adjusted to a valid | ||
| 102 | value or if an error is returned.</para> | ||
| 103 | |||
| 104 | <para>When the <structfield>id</structfield> or | ||
| 105 | <structfield>ctrl_class</structfield> is invalid drivers return an | ||
| 106 | &EINVAL;. When the value is out of bounds drivers can choose to take | ||
| 107 | the closest valid value or return an &ERANGE;, whatever seems more | ||
| 108 | appropriate. In the first case the new value is set in | ||
| 109 | &v4l2-ext-control;.</para> | ||
| 110 | |||
| 111 | <para>The driver will only set/get these controls if all control | ||
| 112 | values are correct. This prevents the situation where only some of the | ||
| 113 | controls were set/get. Only low-level errors (⪚ a failed i2c | ||
| 114 | command) can still cause this situation.</para> | ||

| 59 | |||
| 60 | <para>Applications can use the <constant>VIDIOC_G_FBUF</constant> and | ||
| 61 | <constant>VIDIOC_S_FBUF</constant> ioctl to get and set the | ||
| 62 | framebuffer parameters for a <link linkend="overlay">Video | ||
| 63 | Overlay</link> or <link linkend="osd">Video Output Overlay</link> | ||
| 64 | (OSD). The type of overlay is implied by the device type (capture or | ||
| 65 | output device) and can be determined with the &VIDIOC-QUERYCAP; ioctl. | ||
| 66 | One <filename>/dev/videoN</filename> device must not support both | ||
| 67 | kinds of overlay.</para> | ||
| 68 | |||
| 69 | <para>The V4L2 API distinguishes destructive and non-destructive | ||
| 70 | overlays. A destructive overlay copies captured video images into the | ||
| 71 | video memory of a graphics card. A non-destructive overlay blends | ||
| 72 | video images into a VGA signal or graphics into a video signal. | ||
| 73 | <wordasword>Video Output Overlays</wordasword> are always | ||
| 74 | non-destructive.</para> | ||
| 75 | |||
| 76 | <para>To get the current parameters applications call the | ||
| 77 | <constant>VIDIOC_G_FBUF</constant> ioctl with a pointer to a | ||
| 78 | <structname>v4l2_framebuffer</structname> structure. The driver fills | ||
| 79 | all fields of the structure or returns an &EINVAL; when overlays are | ||
| 80 | not supported.</para> | ||
| 81 | |||
| 82 | <para>To set the parameters for a <wordasword>Video Output | ||
| 83 | Overlay</wordasword>, applications must initialize the | ||
| 84 | <structfield>flags</structfield> field of a struct | ||
| 85 | <structname>v4l2_framebuffer</structname>. Since the framebuffer is | ||
| 86 | implemented on the TV card all other parameters are determined by the | ||
| 87 | driver. When an application calls <constant>VIDIOC_S_FBUF</constant> | ||
| 88 | with a pointer to this structure, the driver prepares for the overlay | ||
| 89 | and returns the framebuffer parameters as | ||
| 90 | <constant>VIDIOC_G_FBUF</constant> does, or it returns an error | ||
| 91 | code.</para> | ||
| 92 | |||
| 93 | <para>To set the parameters for a <wordasword>non-destructive | ||
| 94 | Video Overlay</wordasword>, applications must initialize the | ||
| 95 | <structfield>flags</structfield> field, the | ||
| 96 | <structfield>fmt</structfield> substructure, and call | ||
| 97 | <constant>VIDIOC_S_FBUF</constant>. Again the driver prepares for the | ||
| 98 | overlay and returns the framebuffer parameters as | ||
| 99 | <constant>VIDIOC_G_FBUF</constant> does, or it returns an error | ||
| 100 | code.</para> | ||
| 101 | |||
| 102 | <para>For a <wordasword>destructive Video Overlay</wordasword> | ||
| 103 | applications must additionally provide a | ||
| 104 | <structfield>base</structfield> address. Setting up a DMA to a | ||
| 105 | random memory location can jeopardize the system security, its | ||
| 106 | stability or even damage the hardware, therefore only the superuser | ||
| 107 | can set the parameters for a destructive video overlay.</para> | ||

| 53 | <title>Description</title> | ||
| 54 | |||
| 55 | <para>These ioctls are used to negotiate the format of data | ||
| 56 | (typically image format) exchanged between driver and | ||
| 57 | application.</para> | ||
| 58 | |||
| 59 | <para>To query the current parameters applications set the | ||
| 60 | <structfield>type</structfield> field of a struct | ||
| 61 | <structname>v4l2_format</structname> to the respective buffer (stream) | ||
| 62 | type. For example video capture devices use | ||
| 63 | <constant>V4L2_BUF_TYPE_VIDEO_CAPTURE</constant>. When the application | ||
| 64 | calls the <constant>VIDIOC_G_FMT</constant> ioctl with a pointer to | ||
| 65 | this structure the driver fills the respective member of the | ||
| 66 | <structfield>fmt</structfield> union. In case of video capture devices | ||
| 67 | that is the &v4l2-pix-format; <structfield>pix</structfield> member. | ||
| 68 | When the requested buffer type is not supported drivers return an | ||
| 69 | &EINVAL;.</para> | ||
| 70 | |||
| 71 | <para>To change the current format parameters applications | ||
| 72 | initialize the <structfield>type</structfield> field and all | ||
| 73 | fields of the respective <structfield>fmt</structfield> | ||
| 74 | union member. For details see the documentation of the various devices | ||
| 75 | types in <xref linkend="devices" />. Good practice is to query the | ||
| 76 | current parameters first, and to | ||
| 77 | modify only those parameters not suitable for the application. When | ||
| 78 | the application calls the <constant>VIDIOC_S_FMT</constant> ioctl | ||
| 79 | with a pointer to a <structname>v4l2_format</structname> structure | ||
| 80 | the driver checks | ||
| 81 | and adjusts the parameters against hardware abilities. Drivers | ||
| 82 | should not return an error code unless the input is ambiguous, this is | ||
| 83 | a mechanism to fathom device capabilities and to approach parameters | ||
| 84 | acceptable for both the application and driver. On success the driver | ||
| 85 | may program the hardware, allocate resources and generally prepare for | ||
| 86 | data exchange. | ||
| 87 | Finally the <constant>VIDIOC_S_FMT</constant> ioctl returns the | ||
| 88 | current format parameters as <constant>VIDIOC_G_FMT</constant> does. | ||
| 89 | Very simple, inflexible devices may even ignore all input and always | ||
| 90 | return the default parameters. However all V4L2 devices exchanging | ||
| 91 | data with the application must implement the | ||
| 92 | <constant>VIDIOC_G_FMT</constant> and | ||
| 93 | <constant>VIDIOC_S_FMT</constant> ioctl. When the requested buffer | ||
| 94 | type is not supported drivers return an &EINVAL; on a | ||
| 95 | <constant>VIDIOC_S_FMT</constant> attempt. When I/O is already in | ||
| 96 | progress or the resource is not available for other reasons drivers | ||
| 97 | return the &EBUSY;.</para> | ||
| 98 | |||
| 99 | <para>The <constant>VIDIOC_TRY_FMT</constant> ioctl is equivalent | ||
| 100 | to <constant>VIDIOC_S_FMT</constant> with one exception: it does not | ||
| 101 | change driver state. It can also be called at any time, never | ||
| 102 | returning <errorcode>EBUSY</errorcode>. This function is provided to | ||
| 103 | negotiate parameters, to learn about hardware limitations, without | ||
| 104 | disabling I/O or possibly time consuming hardware preparations. | ||
| 105 | Although strongly recommended drivers are not required to implement | ||
| 106 | this ioctl.</para> | ||

| 60 | <para>To query the attributes of a control applications set the | ||

| 66 | <para>It is possible to enumerate controls by calling | ||

| 69 | <constant>V4L2_CID_BASE</constant> up to and exclusive | ||
| 70 | <constant>V4L2_CID_BASE_LASTP1</constant>. Drivers may return | ||
| 71 | <errorcode>EINVAL</errorcode> if a control in this range is not | ||
| 72 | supported. Further applications can enumerate private controls, which | ||
| 73 | are not defined in this specification, by starting at | ||

| 75 | <structfield>id</structfield> until the driver returns | ||

| 82 | <para><constant>V4L2_CTRL_FLAG_DISABLED</constant> was | ||
| 83 | intended for two purposes: Drivers can skip predefined controls not | ||
| 84 | supported by the hardware (although returning EINVAL would do as | ||
| 85 | well), or disable predefined and private controls after hardware | ||
| 86 | detection without the trouble of reordering control arrays and indices | ||
| 87 | (EINVAL cannot be used to skip private controls because it would | ||
| 88 | prematurely end the enumeration).</para></footnote></para> | ||
| 89 | |||
| 90 | <para>When the application ORs <structfield>id</structfield> with | ||
| 91 | <constant>V4L2_CTRL_FLAG_NEXT_CTRL</constant> the driver returns the | ||

| 93 | none. Drivers which do not support this flag yet always return | ||
| 94 | <errorcode>EINVAL</errorcode>.</para> | ||
| 95 | |||
| 96 | <para>Additional information is required for menu controls: the | ||
| 97 | names of the menu items. To query them applications set the | ||
| 98 | <structfield>id</structfield> and <structfield>index</structfield> | ||
| 99 | fields of &v4l2-querymenu; and call the | ||
| 100 | <constant>VIDIOC_QUERYMENU</constant> ioctl with a pointer to this | ||

| 102 | &EINVAL; when the <structfield>id</structfield> or | ||
| 103 | <structfield>index</structfield> is invalid. Menu items are enumerated | ||
| 104 | by calling <constant>VIDIOC_QUERYMENU</constant> with successive | ||

| 51 | <para>This ioctl is used to initiate <link linkend="mmap">memory | ||
| 52 | mapped</link> or <link linkend="userp">user pointer</link> | ||
| 53 | I/O. Memory mapped buffers are located in device memory and must be | ||
| 54 | allocated with this ioctl before they can be mapped into the | ||
| 55 | application's address space. User buffers are allocated by | ||
| 56 | applications themselves, and this ioctl is merely used to switch the | ||
| 57 | driver into user pointer I/O mode.</para> | ||
| 58 | |||
| 59 | <para>To allocate device buffers applications initialize three | ||
| 60 | fields of a <structname>v4l2_requestbuffers</structname> structure. | ||
| 61 | They set the <structfield>type</structfield> field to the respective | ||
| 62 | stream or buffer type, the <structfield>count</structfield> field to | ||
| 63 | the desired number of buffers, and <structfield>memory</structfield> | ||
| 64 | must be set to <constant>V4L2_MEMORY_MMAP</constant>. When the ioctl | ||
| 65 | is called with a pointer to this structure the driver attempts to | ||
| 66 | allocate the requested number of buffers and stores the actual number | ||
| 67 | allocated in the <structfield>count</structfield> field. It can be | ||
| 68 | smaller than the number requested, even zero, when the driver runs out | ||
| 69 | of free memory. A larger number is possible when the driver requires | ||
| 70 | more buffers to function correctly.<footnote> | ||
| 71 | <para>For example video output requires at least two buffers, | ||
| 72 | one displayed and one filled by the application.</para> | ||
| 73 | </footnote> When memory mapping I/O is not supported the ioctl | ||
| 74 | returns an &EINVAL;.</para> | ||
| 75 | |||
| 76 | <para>Applications can call <constant>VIDIOC_REQBUFS</constant> | ||
| 77 | again to change the number of buffers, however this cannot succeed | ||
| 78 | when any buffers are still mapped. A <structfield>count</structfield> | ||
| 79 | value of zero frees all buffers, after aborting or finishing any DMA | ||
| 80 | in progress, an implicit &VIDIOC-STREAMOFF;. <!-- mhs: I see no | ||
| 81 | reason why munmap()ping one or even all buffers must imply | ||
| 82 | streamoff.--></para> | ||
| 83 | |||
| 84 | <para>To negotiate user pointer I/O, applications initialize only | ||
| 85 | the <structfield>type</structfield> field and set | ||
| 86 | <structfield>memory</structfield> to | ||
| 87 | <constant>V4L2_MEMORY_USERPTR</constant>. When the ioctl is called | ||
| 88 | with a pointer to this structure the driver prepares for user pointer | ||
| 89 | I/O, when this I/O method is not supported the ioctl returns an | ||

| 52 | <para>The <constant>VIDIOC_STREAMON</constant> and | ||

| 54 | or output process during streaming (<link linkend="mmap">memory | ||
| 55 | mapping</link> or <link linkend="userp">user pointer</link>) I/O.</para> | ||
| 56 | |||
| 57 | <para>Specifically the capture hardware is disabled and no input | ||
| 58 | buffers are filled (if there are any empty buffers in the incoming | ||
| 59 | queue) until <constant>VIDIOC_STREAMON</constant> has been called. | ||
| 60 | Accordingly the output hardware is disabled, no video signal is | ||
| 61 | produced until <constant>VIDIOC_STREAMON</constant> has been called. | ||
| 62 | The ioctl will succeed only when at least one output buffer is in the | ||
| 63 | incoming queue.</para> | ||
| 64 | |||
| 65 | <para>The <constant>VIDIOC_STREAMOFF</constant> ioctl, apart of | ||
| 66 | aborting or finishing any DMA in progress, unlocks any user pointer | ||
| 67 | buffers locked in physical memory, and it removes all buffers from the | ||
| 68 | incoming and outgoing queues. That means all images captured but not | ||
| 69 | dequeued yet will be lost, likewise all images enqueued for output but | ||
| 70 | not transmitted yet. I/O returns to the same state as after calling | ||
| 71 | &VIDIOC-REQBUFS; and can be restarted accordingly.</para> | ||
| 72 | |||
| 73 | <para>Both ioctls take a pointer to an integer, the desired buffer or | ||
| 74 | stream type. This is the same as &v4l2-requestbuffers; | ||
| 75 | <structfield>type</structfield>.</para> | ||
| 76 | |||
| 77 | <para>Note applications can be preempted for unknown periods right | ||
| 78 | before or after the <constant>VIDIOC_STREAMON</constant> or | ||
| 79 | <constant>VIDIOC_STREAMOFF</constant> calls, there is no notion of | ||

| 119 | VIDIOC_S_CROP and VIDIOC_S_FMT behaviour | ||
| 120 | ---------------------------------------- | ||
| 121 | |||
| 122 | Above user ioctls modify image geometry as follows: | ||
| 123 | |||
| 124 | VIDIOC_S_CROP: sets location and sizes of the sensor window. Unit is one sensor | ||
| 125 | pixel. Changing sensor window sizes preserves any scaling factors, therefore | ||
| 126 | user window sizes change as well. | ||
| 127 | |||
| 128 | VIDIOC_S_FMT: sets user window. Should preserve previously set sensor window as | ||
| 129 | much as possible by modifying scaling factors. If the sensor window cannot be | ||
| 130 | preserved precisely, it may be changed too. | ||
| 131 | |||
| 132 | In soc-camera there are two locations, where scaling and cropping can taks | ||
| 133 | place: in the camera driver and in the host driver. User ioctls are first passed | ||
| 134 | to the host driver, which then generally passes them down to the camera driver. | ||
| 135 | It is more efficient to perform scaling and cropping in the camera driver to | ||
| 136 | save camera bus bandwidth and maximise the framerate. However, if the camera | ||
| 137 | driver failed to set the required parameters with sufficient precision, the host | ||
| 138 | driver may decide to also use its own scaling and cropping to fulfill the user's | ||
| 139 | request. | ||
| 140 | |||
| 141 | Camera drivers are interfaced to the soc-camera core and to host drivers over | ||
| 142 | the v4l2-subdev API, which is completely functional, it doesn't pass any data. | ||
| 143 | Therefore all camera drivers shall reply to .g_fmt() requests with their current | ||
| 144 | output geometry. This is necessary to correctly configure the camera bus. | ||
| 145 | .s_fmt() and .try_fmt() have to be implemented too. Sensor window and scaling | ||
| 146 | factors have to be maintained by camera drivers internally. According to the | ||
| 147 | V4L2 API all capture drivers must support the VIDIOC_CROPCAP ioctl, hence we | ||
| 148 | rely on camera drivers implementing .cropcap(). If the camera driver does not | ||
| 149 | support cropping, it may choose to not implement .s_crop(), but to enable | ||
| 150 | cropping support by the camera host driver at least the .g_crop method must be | ||
| 151 | implemented. | ||
| 152 | |||
| 153 | User window geometry is kept in .user_width and .user_height fields in struct | ||
| 154 | soc_camera_device and used by the soc-camera core and host drivers. The core | ||
| 155 | updates these fields upon successful completion of a .s_fmt() call, but if these | ||
| 156 | fields change elsewhere, e.g., during .s_crop() processing, the host driver is | ||
| 157 | responsible for updating them. | ||

| 18 | * CCDC hardware module for DM355 | ||
| 19 | * ------------------------------ | ||
| 20 | * | ||
| 21 | * This module is for configuring DM355 CCD controller of VPFE to capture | ||
| 22 | * Raw yuv or Bayer RGB data from a decoder. CCDC has several modules | ||
| 23 | * such as Defect Pixel Correction, Color Space Conversion etc to | ||
| 24 | * pre-process the Bayer RGB data, before writing it to SDRAM. This | ||
| 25 | * module also allows application to configure individual | ||
| 26 | * module parameters through VPFE_CMD_S_CCDC_RAW_PARAMS IOCTL. | ||
| 27 | * To do so, application include dm355_ccdc.h and vpfe_capture.h header | ||
| 28 | * files. The setparams() API is called by vpfe_capture driver | ||
| 29 | * to configure module parameters | ||
| 30 | * | ||
| 31 | * TODO: 1) Raw bayer parameter settings and bayer capture | ||
| 32 | * 2) Split module parameter structure to module specific ioctl structs | ||
| 33 | * 3) add support for lense shading correction | ||
| 34 | * 4) investigate if enum used for user space type definition | ||
| 35 | * to be replaced by #defines or integer | ||

| 19 | * ------------------------------ | ||
| 20 | * | ||
| 21 | * This module is for configuring CCD controller of DM6446 VPFE to capture | ||
| 22 | * Raw yuv or Bayer RGB data from a decoder. CCDC has several modules | ||
| 23 | * such as Defect Pixel Correction, Color Space Conversion etc to | ||
| 24 | * pre-process the Raw Bayer RGB data, before writing it to SDRAM. This | ||
| 25 | * module also allows application to configure individual | ||
| 26 | * module parameters through VPFE_CMD_S_CCDC_RAW_PARAMS IOCTL. | ||
| 27 | * To do so, application includes dm644x_ccdc.h and vpfe_capture.h header | ||
| 28 | * files. The setparams() API is called by vpfe_capture driver | ||
| 29 | * to configure module parameters. This file is named DM644x so that other | ||
| 30 | * variants such DM6443 may be supported using the same module. | ||
| 31 | * | ||
| 32 | * TODO: Test Raw bayer parameter settings and bayer capture | ||
| 33 | * Split module parameter structure to module specific ioctl structs | ||
| 34 | * investigate if enum used for user space type definition | ||
| 35 | * to be replaced by #defines or integer | ||

| 18 | * Driver name : VPFE Capture driver | ||
| 19 | * VPFE Capture driver allows applications to capture and stream video | ||
| 20 | * frames on DaVinci SoCs (DM6446, DM355 etc) from a YUV source such as | ||
| 21 | * TVP5146 or Raw Bayer RGB image data from an image sensor | ||
| 22 | * such as Microns' MT9T001, MT9T031 etc. | ||
| 23 | * | ||
| 24 | * These SoCs have, in common, a Video Processing Subsystem (VPSS) that | ||
| 25 | * consists of a Video Processing Front End (VPFE) for capturing | ||
| 26 | * video/raw image data and Video Processing Back End (VPBE) for displaying | ||
| 27 | * YUV data through an in-built analog encoder or Digital LCD port. This | ||
| 28 | * driver is for capture through VPFE. A typical EVM using these SoCs have | ||
| 29 | * following high level configuration. | ||
| 30 | * | ||
| 31 | * | ||
| 32 | * decoder(TVP5146/ YUV/ | ||
| 33 | * MT9T001) --> Raw Bayer RGB ---> MUX -> VPFE (CCDC/ISIF) | ||
| 34 | * data input | | | ||
| 35 | * V | | ||
| 36 | * SDRAM | | ||
| 37 | * V | ||
| 38 | * Image Processor | ||
| 39 | * | | ||
| 40 | * V | ||
| 41 | * SDRAM | ||
| 42 | * The data flow happens from a decoder connected to the VPFE over a | ||
| 43 | * YUV embedded (BT.656/BT.1120) or separate sync or raw bayer rgb interface | ||
| 44 | * and to the input of VPFE through an optional MUX (if more inputs are | ||
| 45 | * to be interfaced on the EVM). The input data is first passed through | ||
| 46 | * CCDC (CCD Controller, a.k.a Image Sensor Interface, ISIF). The CCDC | ||
| 47 | * does very little or no processing on YUV data and does pre-process Raw | ||
| 48 | * Bayer RGB data through modules such as Defect Pixel Correction (DFC) | ||
| 49 | * Color Space Conversion (CSC), data gain/offset etc. After this, data | ||
| 50 | * can be written to SDRAM or can be connected to the image processing | ||
| 51 | * block such as IPIPE (on DM355 only). | ||
| 52 | * | ||
| 53 | * Features supported | ||
| 54 | * - MMAP IO | ||
| 55 | * - Capture using TVP5146 over BT.656 | ||
| 56 | * - support for interfacing decoders using sub device model | ||
| 57 | * - Work with DM355 or DM6446 CCDC to do Raw Bayer RGB/YUV | ||
| 58 | * data capture to SDRAM. | ||
| 59 | * TODO list | ||
| 60 | * - Support multiple REQBUF after open | ||
| 61 | * - Support for de-allocating buffers through REQBUF | ||
| 62 | * - Support for Raw Bayer RGB capture | ||
| 63 | * - Support for chaining Image Processor | ||
| 64 | * - Support for static allocation of buffers | ||
| 65 | * - Support for USERPTR IO | ||
| 66 | * - Support for STREAMON before QBUF | ||
| 67 | * - Support for control ioctls | ||
