37 | 0. OVERVIEW AND LICENSING/DISCLAIMER | ||
38 | |||
39 | |||
40 | This driver kit contains Linux drivers for the WIS GO7007SB multi-format | ||
41 | video encoder. Only kernel version 2.6.x is supported. The video stream | ||
42 | is available through the Video4Linux2 API and the audio stream is available | ||
43 | through the ALSA API (or the OSS emulation layer of the ALSA system). | ||
44 | |||
45 | The files in kernel/ and hotplug/ are licensed under the GNU General Public | ||
46 | License Version 2 from the Free Software Foundation. A copy of the license | ||
47 | is included in the file COPYING. | ||
48 | |||
49 | The example applications in apps/ and C header files in include/ are | ||
50 | licensed under a permissive license included in the source files which | ||
51 | allows copying, modification and redistribution for any purpose without | ||
52 | attribution. | ||
53 | |||
54 | The firmware files included in the firmware/ directory may be freely | ||
55 | redistributed only in conjunction with this document; but modification, | ||
56 | tampering and reverse engineering are prohibited. | ||

59 | RESPECT TO THE SOFTWARE OR ANY DERIVATIVES THEREOF OR ANY SERVICES OR | ||
60 | LICENSES AND DISCLAIMS ALL IMPLIED WARRANTIES, INCLUDING WITHOUT LIMITATION | ||
61 | WARRANTIES OF MERCHANTABILITY, SUPPORT, AND FITNESS FOR A PARTICULAR | ||
62 | PURPOSE AND NON-INFRINGEMENT. | ||
63 | |||
64 | |||
65 | 1. SYSTEM REQUIREMENTS | ||
66 | |||
67 | |||
68 | This driver requires Linux kernel 2.6. Kernel 2.4 is not supported. Using | ||
69 | kernel 2.6.10 or later is recommended, as earlier kernels are known to have | ||
70 | unstable USB 2.0 support. | ||
71 | |||
72 | A fully built kernel source tree must be available. Typically this will be | ||
73 | linked from "/lib/modules/<KERNEL VERSION>/build" for convenience. If this | ||
74 | link does not exist, an extra parameter will need to be passed to the | ||
75 | `make` command. | ||
76 | |||
77 | All vendor-built kernels should already be configured properly. However, | ||
78 | for custom-built kernels, the following options need to be enabled in the | ||
79 | kernel as built-in or modules: | ||
80 | |||
81 | CONFIG_HOTPLUG - Support for hot-pluggable devices | ||
82 | CONFIG_MODULES - Enable loadable module support | ||
83 | CONFIG_KMOD - Automatic kernel module loading | ||
84 | CONFIG_FW_LOADER - Hotplug firmware loading support | ||
85 | CONFIG_I2C - I2C support | ||
86 | CONFIG_VIDEO_DEV - Video For Linux | ||
87 | CONFIG_SOUND - Sound card support | ||
88 | CONFIG_SND - Advanced Linux Sound Architecture | ||
89 | CONFIG_USB - Support for Host-side USB | ||
90 | CONFIG_USB_DEVICEFS - USB device filesystem | ||
91 | CONFIG_USB_EHCI_HCD - EHCI HCD (USB 2.0) support | ||
92 | |||
93 | Additionally, to use the example application, the following options need to | ||
94 | be enabled in the ALSA section: | ||
95 | |||
96 | CONFIG_SND_MIXER_OSS - OSS Mixer API | ||
97 | CONFIG_SND_PCM_OSS - OSS PCM (digital audio) API | ||
98 | |||
99 | The hotplug scripts, along with the fxload utility, must also be installed. | ||
100 | These scripts can be obtained from <http://linux-hotplug.sourceforge.net/>. | ||
101 | Hotplugging is used for loading firmware into the Cypruss EZ-USB chip using | ||
102 | fxload and for loading firmware into the driver using the firmware agent. | ||
103 | |||
104 | |||
105 | 2. COMPILING AND INSTALLING THE DRIVER | ||
106 | |||
107 | |||
108 | Most users should be able to compile the driver by simply running: | ||
109 | |||
110 | $ make | ||
111 | |||
112 | in the top-level directory of the driver kit. First the kernel modules | ||
113 | will be built, followed by the example applications. | ||
114 | |||
115 | If the build system is unable to locate the kernel source tree for the | ||
116 | currently-running kernel, or if the module should be built for a kernel | ||
117 | other than the currently-running kernel, an additional parameter will need | ||
118 | to be passed to make to specify the appropriate kernel source directory: | ||
119 | |||
120 | $ make KERNELSRC=/usr/src/linux-2.6.10-custom3 | ||
121 | |||
122 | Once the compile completes, the driver and firmware files should be | ||
123 | installed by running: | ||
124 | |||
125 | $ make install | ||
126 | |||
127 | The kernel modules will be placed in "/lib/modules/<KERNEL VERSION>/extra" | ||
128 | and the firmware files will be placed in the appropriate hotplug firmware | ||
129 | directory, usually /lib/firmware. In addition, USB maps and scripts will | ||
130 | be placed in /etc/hotplug/usb to enable fxload to initialize the EZ-USB | ||
131 | control chip when the device is connected. | ||
132 | |||
133 | |||
134 | 3. PAL/SECAM TUNER CONFIGURATION (TV402U-EU only) | ||
135 | |||
136 | |||
137 | The PAL model of the Plextor ConvertX TV402U may require additional | ||
138 | configuration to correctly select the appropriate TV frequency band and | ||
139 | audio subchannel. | ||
140 | |||
141 | Users with a device other than the Plextor ConvertX TV402U-EU should skip | ||
142 | this section. | ||
143 | |||
144 | The wide variety of PAL TV systems used in Europe requires that additional | ||
145 | information about the local TV standards be passed to the driver in order | ||
146 | to properly tune TV channels. The two necessary parameters are (a) the PAL | ||
147 | TV band, and (b) the audio subchannel format in use. | ||
148 | |||
149 | In many cases, the appropriate TV band selection is passed to the driver | ||
150 | from applications. However, in some cases, the application only specifies | ||
151 | that the driver should use PAL but not the specific information about the | ||
152 | appropriate TV band. To work around this issue, the correct TV band may be | ||
153 | specified in the "force_band" parameter to the wis-sony-tuner module: | ||
154 | |||
155 | TV band force_band | ||
156 | ------- ---------- | ||
157 | PAL B/G B | ||
158 | PAL I I | ||
159 | PAL D/K D | ||
160 | SECAM L L | ||
161 | |||
162 | If the "force_band" parameter is specified, the driver will ignore any TV | ||
163 | band specified by applications and will always use the band provided in the | ||
164 | module parameter. | ||
165 | |||
166 | The other parameter that can be specified is the audio subchannel format. | ||
167 | There are several stereo audio carrier systems in use, including NICAM and | ||
168 | three varieties of A2. To receive audio broadcast on one of these stereo | ||
169 | carriers, the "force_mpx_mode" parameter must be specified to the | ||
170 | wis-sony-tuner module. | ||
171 | |||
172 | TV band Audio subcarrier force_mpx_mode | ||
173 | ------- ---------------- -------------- | ||
174 | PAL B/G Mono (default) 1 | ||
175 | PAL B/G A2 2 | ||
176 | PAL B/G NICAM 3 | ||
177 | PAL I Mono (default) 4 | ||
178 | PAL I NICAM 5 | ||
179 | PAL D/K Mono (default) 6 | ||
180 | PAL D/K A2 (1) 7 | ||
181 | PAL D/K A2 (2) 8 | ||
182 | PAL D/K A2 (3) 9 | ||
183 | PAL D/K NICAM 10 | ||
184 | SECAM L Mono (default) 11 | ||
185 | SECAM L NICAM 12 | ||
186 | |||
187 | If the "force_mpx_mode" parameter is not specified, the correct mono-only | ||
188 | mode will be chosen based on the TV band. However, the tuner will not | ||
189 | receive stereo audio or bilingual broadcasts correctly. | ||
190 | |||
191 | To pass the "force_band" or "force_mpx_mode" parameters to the | ||
192 | wis-sony-tuner module, the following line must be added to the modprobe | ||
193 | configuration file, which varies from one Linux distribution to another. | ||
194 | |||
195 | options wis-sony-tuner force_band=B force_mpx_mode=2 | ||
196 | |||
197 | The above example would force the tuner to the PAL B/G TV band and receive | ||
198 | stereo audio broadcasts on the A2 carrier. | ||
199 | |||
200 | To verify that the configuration has been placed in the correct location, | ||
201 | execute: | ||
202 | |||
203 | $ modprobe -c | grep wis-sony-tuner | ||
204 | |||
205 | If the configuration line appears, then modprobe will pass the parameters | ||
206 | correctly the next time the wis-sony-tuner module is loaded into the | ||
207 | kernel. | ||
208 | |||
209 | |||
210 | 4. TESTING THE DRIVER | ||
211 | |||
212 | |||
213 | Because few Linux applications are able to correctly capture from | ||
214 | Video4Linux2 devices with only compressed formats supported, the new driver | ||
215 | should be tested with the "gorecord" application in the apps/ directory. | ||
216 | |||
217 | First connect a video source to the device, such as a DVD player or VCR. | ||
218 | This will be captured to a file for testing the driver. If an input source | ||
219 | is unavailable, a test file can still be captured, but the video will be | ||
220 | black and the audio will be silent. | ||
221 | |||
222 | This application will auto-detect the V4L2 and ALSA/OSS device names of the | ||
223 | hardware and will record video and audio to an AVI file for a specified | ||
224 | number of seconds. For example: | ||
225 | |||
226 | $ apps/gorecord -duration 60 capture.avi | ||
227 | |||
228 | If this application does not successfully record an AVI file, the error | ||
229 | messages produced by gorecord and recorded in the system log (usually in | ||
230 | /var/log/messages) should provide information to help resolve the problem. | ||
231 | |||
232 | Supplying no parameters to gorecord will cause it to probe the available | ||
233 | devices and exit. Use the -help flag for usage information. | ||
234 | |||
235 | |||
236 | 5. USING THE DRIVER | ||
237 | |||
238 | |||
239 | The V4L2 device implemented by the driver provides a standard compressed | ||
240 | format API, within the following criteria: | ||
241 | |||
242 | * Applications that only support the original Video4Linux1 API will not | ||
243 | be able to communicate with this driver at all. | ||
244 | |||
245 | * No raw video modes are supported, so applications like xawtv that | ||
246 | expect only uncompressed video will not function. | ||
247 | |||
248 | * Supported compression formats are: Motion-JPEG, MPEG1, MPEG2 and MPEG4. | ||
249 | |||
250 | * MPEG video formats are delivered as Video Elementary Streams only. | ||
251 | Program Stream (PS), Transport Stream (TS) and Packetized Elementary | ||
252 | Stream (PES) formats are not supported. | ||
253 | |||
254 | * Video parameters such as format and input port may not be changed while | ||
255 | the encoder is active. | ||
256 | |||
257 | * The audio capture device only functions when the video encoder is | ||
258 | actively capturing video. Attempts to read from the audio device when | ||
259 | the encoder is inactive will result in an I/O error. | ||
260 | |||
261 | * The native format of the audio device is 48Khz 2-channel 16-bit | ||
262 | little-endian PCM, delivered through the ALSA system. No audio | ||
263 | compression is implemented in the hardware. ALSA may convert to other | ||
264 | uncompressed formats on the fly. | ||
265 | |||
266 | The include/ directory contains a C header file describing non-standard | ||
267 | features of the GO7007SB encoder, which are described below: | ||
268 | |||
269 | |||
270 | GO7007IOC_S_COMP_PARAMS, GO7007IOC_G_COMP_PARAMS | ||
271 | |||
272 | These ioctls are used to negotiate general compression parameters. | ||
273 | |||
274 | To query the current parameters, call the GO7007IOC_G_COMP_PARAMS ioctl | ||
275 | with a pointer to a struct go7007_comp_params. If the driver is not | ||
276 | set to MPEG format, the EINVAL error code will be returned. | ||
277 | |||
278 | To change the current parameters, initialize all fields of a struct | ||
279 | go7007_comp_params and call the GO7007_IOC_S_COMP_PARAMS ioctl with a | ||
280 | pointer to this structure. The driver will return the current | ||
281 | parameters with any necessary changes to conform to the limitations of | ||
282 | the hardware or current compression mode. Any or all fields can be set | ||
283 | to zero to request a reasonable default value. If the driver is not | ||
284 | set to MPEG format, the EINVAL error code will be returned. When I/O | ||
285 | is in progress, the EBUSY error code will be returned. | ||
286 | |||
287 | Fields in struct go7007_comp_params: | ||
288 | |||
289 | __u32 The maximum number of frames in each | ||
290 | gop_size Group Of Pictures; i.e. the maximum | ||
291 | number of frames minus one between | ||
292 | each key frame. | ||
293 | |||
294 | __u32 The maximum number of sequential | ||
295 | max_b_frames bidirectionally-predicted frames. | ||
296 | (B-frames are not yet supported.) | ||
297 | |||
298 | enum go7007_aspect_ratio The aspect ratio to be encoded in the | ||
299 | aspect_ratio meta-data of the compressed format. | ||
300 | |||
301 | Choices are: | ||
302 | GO7007_ASPECT_RATIO_1_1 | ||
303 | GO7007_ASPECT_RATIO_4_3_NTSC | ||
304 | GO7007_ASPECT_RATIO_4_3_PAL | ||
305 | GO7007_ASPECT_RATIO_16_9_NTSC | ||
306 | GO7007_ASPECT_RATIO_16_9_PAL | ||
307 | |||
308 | __u32 Bit-wise OR of control flags (below) | ||
309 | flags | ||
310 | |||
311 | Flags in struct go7007_comp_params: | ||
312 | |||
313 | GO7007_COMP_CLOSED_GOP Only produce self-contained GOPs, used | ||
314 | to produce streams appropriate for | ||
315 | random seeking. | ||
316 | |||
317 | GO7007_COMP_OMIT_SEQ_HEADER Omit the stream sequence header. | ||
318 | |||
319 | |||
320 | GO7007IOC_S_MPEG_PARAMS, GO7007IOC_G_MPEG_PARAMS | ||
321 | |||
322 | These ioctls are used to negotiate MPEG-specific stream parameters when | ||
323 | the pixelformat has been set to V4L2_PIX_FMT_MPEG. | ||
324 | |||
325 | To query the current parameters, call the GO7007IOC_G_MPEG_PARAMS ioctl | ||
326 | with a pointer to a struct go7007_mpeg_params. If the driver is not | ||
327 | set to MPEG format, the EINVAL error code will be returned. | ||
328 | |||
329 | To change the current parameters, initialize all fields of a struct | ||
330 | go7007_mpeg_params and call the GO7007_IOC_S_MPEG_PARAMS ioctl with a | ||
331 | pointer to this structure. The driver will return the current | ||
332 | parameters with any necessary changes to conform to the limitations of | ||
333 | the hardware or selected MPEG mode. Any or all fields can be set to | ||
334 | zero to request a reasonable default value. If the driver is not set | ||
335 | to MPEG format, the EINVAL error code will be returned. When I/O is in | ||
336 | progress, the EBUSY error code will be returned. | ||
337 | |||
338 | Fields in struct go7007_mpeg_params: | ||
339 | |||
340 | enum go7007_mpeg_video_standard | ||
341 | mpeg_video_standard The MPEG video standard in which to | ||
342 | compress the video. | ||
343 | |||

386 | GO7007_MPEG_OMIT_GOP_HEADER Omit the GOP header. | ||
387 | |||

391 | |||
392 | GO7007IOC_S_BITRATE, GO7007IOC_G_BITRATE | ||
393 | |||
394 | These ioctls are used to set and query the target bitrate value for the | ||
395 | compressed video stream. The bitrate may be selected by storing the | ||
396 | target bits per second in an int and calling GO7007IOC_S_BITRATE with a | ||
397 | pointer to the int. The bitrate may be queried by calling | ||
398 | GO7007IOC_G_BITRATE with a pointer to an int where the current bitrate | ||
399 | will be stored. | ||
400 | |||
401 | Note that this is the primary means of controlling the video quality | ||
402 | for all compression modes, including V4L2_PIX_FMT_MJPEG. The | ||
403 | VIDIOC_S_JPEGCOMP ioctl is not supported. | ||

407 | Installing the WIS PCI Voyager Driver | ||
408 | --------------------------------------------------------------------------- | ||
409 | |||
410 | The WIS PCI Voyager driver requires several patches to the Linux 2.6.11.x | ||
411 | kernel source tree before compiling the driver. These patches update the | ||
412 | in-kernel SAA7134 driver to the newest development version and patch bugs | ||
413 | in the TDA8290/TDA8275 tuner driver. | ||
414 | |||
415 | The following patches must be downloaded from Gerd Knorr's website and | ||
416 | applied in the order listed: | ||
417 | |||
418 | http://dl.bytesex.org/patches/2.6.11-2/i2c-tuner | ||
419 | http://dl.bytesex.org/patches/2.6.11-2/i2c-tuner2 | ||
420 | http://dl.bytesex.org/patches/2.6.11-2/v4l2-api-mpeg | ||
421 | http://dl.bytesex.org/patches/2.6.11-2/saa7134-update | ||
422 | |||
423 | The following patches are included with this SDK and can be applied in any | ||
424 | order: | ||
425 | |||
426 | patches/2.6.11/saa7134-voyager.diff | ||
427 | patches/2.6.11/tda8275-newaddr.diff | ||
428 | patches/2.6.11/tda8290-ntsc.diff | ||
429 | |||
430 | Check to make sure the CONFIG_VIDEO_SAA7134 option is enabled in the kernel | ||
431 | configuration, and build and install the kernel. | ||
432 | |||
433 | After rebooting into the new kernel, the GO7007 driver can be compiled and | ||
434 | installed: | ||
435 | |||
436 | $ make SAA7134_BUILD=y | ||
437 | $ make install | ||
438 | $ modprobe saa7134-go7007 | ||
439 | |||
440 | There will be two V4L video devices associated with the PCI Voyager. The | ||
441 | first device (most likely /dev/video0) provides access to the raw video | ||
442 | capture mode of the SAA7133 device and is used to configure the source | ||
443 | video parameters and tune the TV tuner. This device can be used with xawtv | ||
444 | or other V4L(2) video software as a standard uncompressed device. | ||
445 | |||
446 | The second device (most likely /dev/video1) provides access to the | ||
447 | compression functions of the GO7007. It can be tested using the gorecord | ||
448 | application in the apps/ directory of this SDK: | ||
449 | |||
450 | $ apps/gorecord -vdevice /dev/video1 -noaudio test.avi | ||
451 | |||
452 | Currently the frame resolution is fixed at 720x480 (NTSC) or 720x576 (PAL), | ||
453 | and the video standard must be specified to both the raw and the compressed | ||
454 | video devices (xawtv and gorecord, for example). | ||
455 | |||

458 | RELEASE NOTES FOR WIS GO7007SB LINUX DRIVER | ||
459 | --------------------------------------------------------------------------- | ||
460 | |||
461 | Last updated: 5 November 2005 | ||
462 | |||
463 | - Release 0.9.7 includes new support for using udev to run fxload. The | ||
464 | install script should automatically detect whether the old hotplug | ||
465 | scripts or the new udev rules should be used. To force the use of | ||
466 | hotplug, run "make install USE_UDEV=n". To force the use of udev, run | ||
467 | "make install USE_UDEV=y". | ||
468 | |||
469 | - Motion detection is supported but undocumented. Try the `modet` app | ||
470 | for a demonstration of how to use the facility. | ||
471 | |||
472 | - Using USB2.0 devices such as the TV402U with USB1.1 HCDs or hubs can | ||
473 | cause buffer overruns and frame drops, even at low framerates, due to | ||
474 | inconsistency in the bitrate control mechanism. | ||
475 | |||
476 | - On devices with an SAA7115, including the Plextor ConvertX, video height | ||
477 | values of 96, 128, 160, 192, 256, 320, and 384 do not work in NTSC mode. | ||
478 | All valid heights up to 512 work correctly in PAL mode. | ||
479 | |||
480 | - The WIS Star Trek and PCI Voyager boards have no support yet for audio | ||
481 | or the TV tuner. | ||
