1Todo:
2 - checkpatch.pl cleanups
3 - sparse cleanups
4 - lots of little modules, should be merged together
5 and added to the build.
6 - testing?
7 - handle churn in v4l layer.

37 0. OVERVIEW AND LICENSING/DISCLAIMER
38
39
40This driver kit contains Linux drivers for the WIS GO7007SB multi-format
41video encoder. Only kernel version 2.6.x is supported. The video stream
42is available through the Video4Linux2 API and the audio stream is available
43through the ALSA API (or the OSS emulation layer of the ALSA system).
44
45The files in kernel/ and hotplug/ are licensed under the GNU General Public
46License Version 2 from the Free Software Foundation. A copy of the license
47is included in the file COPYING.
48
49The example applications in apps/ and C header files in include/ are
50licensed under a permissive license included in the source files which
51allows copying, modification and redistribution for any purpose without
52attribution.
53
54The firmware files included in the firmware/ directory may be freely
55redistributed only in conjunction with this document; but modification,
56tampering and reverse engineering are prohibited.
57
58MICRONAS USA, INC., MAKES NO WARRANTIES TO ANY PERSON OR ENTITY WITH
59RESPECT TO THE SOFTWARE OR ANY DERIVATIVES THEREOF OR ANY SERVICES OR
60LICENSES AND DISCLAIMS ALL IMPLIED WARRANTIES, INCLUDING WITHOUT LIMITATION
61WARRANTIES OF MERCHANTABILITY, SUPPORT, AND FITNESS FOR A PARTICULAR
62PURPOSE AND NON-INFRINGEMENT.
63
64
65 1. SYSTEM REQUIREMENTS
66
67
68This driver requires Linux kernel 2.6. Kernel 2.4 is not supported. Using
69kernel 2.6.10 or later is recommended, as earlier kernels are known to have
70unstable USB 2.0 support.
71
72A fully built kernel source tree must be available. Typically this will be
73linked from "/lib/modules/<KERNEL VERSION>/build" for convenience. If this
74link does not exist, an extra parameter will need to be passed to the
75`make` command.
76
77All vendor-built kernels should already be configured properly. However,
78for custom-built kernels, the following options need to be enabled in the
79kernel 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
93Additionally, to use the example application, the following options need to
94be 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
99The hotplug scripts, along with the fxload utility, must also be installed.
100These scripts can be obtained from <http://linux-hotplug.sourceforge.net/>.
101Hotplugging is used for loading firmware into the Cypruss EZ-USB chip using
102fxload and for loading firmware into the driver using the firmware agent.
103
104
105 2. COMPILING AND INSTALLING THE DRIVER
106
107
108Most users should be able to compile the driver by simply running:
109
110 $ make
111
112in the top-level directory of the driver kit. First the kernel modules
113will be built, followed by the example applications.
114
115If the build system is unable to locate the kernel source tree for the
116currently-running kernel, or if the module should be built for a kernel
117other than the currently-running kernel, an additional parameter will need
118to be passed to make to specify the appropriate kernel source directory:
119
120 $ make KERNELSRC=/usr/src/linux-2.6.10-custom3
121
122Once the compile completes, the driver and firmware files should be
123installed by running:
124
125 $ make install
126
127The kernel modules will be placed in "/lib/modules/<KERNEL VERSION>/extra"
128and the firmware files will be placed in the appropriate hotplug firmware
129directory, usually /lib/firmware. In addition, USB maps and scripts will
130be placed in /etc/hotplug/usb to enable fxload to initialize the EZ-USB
131control chip when the device is connected.
132
133
134 3. PAL/SECAM TUNER CONFIGURATION (TV402U-EU only)
135
136
137The PAL model of the Plextor ConvertX TV402U may require additional
138configuration to correctly select the appropriate TV frequency band and
139audio subchannel.
140
141Users with a device other than the Plextor ConvertX TV402U-EU should skip
142this section.
143
144The wide variety of PAL TV systems used in Europe requires that additional
145information about the local TV standards be passed to the driver in order
146to properly tune TV channels. The two necessary parameters are (a) the PAL
147TV band, and (b) the audio subchannel format in use.
148
149In many cases, the appropriate TV band selection is passed to the driver
150from applications. However, in some cases, the application only specifies
151that the driver should use PAL but not the specific information about the
152appropriate TV band. To work around this issue, the correct TV band may be
153specified 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
162If the "force_band" parameter is specified, the driver will ignore any TV
163band specified by applications and will always use the band provided in the
164module parameter.
165
166The other parameter that can be specified is the audio subchannel format.
167There are several stereo audio carrier systems in use, including NICAM and
168three varieties of A2. To receive audio broadcast on one of these stereo
169carriers, the "force_mpx_mode" parameter must be specified to the
170wis-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
187If the "force_mpx_mode" parameter is not specified, the correct mono-only
188mode will be chosen based on the TV band. However, the tuner will not
189receive stereo audio or bilingual broadcasts correctly.
190
191To pass the "force_band" or "force_mpx_mode" parameters to the
192wis-sony-tuner module, the following line must be added to the modprobe
193configuration file, which varies from one Linux distribution to another.
194
195 options wis-sony-tuner force_band=B force_mpx_mode=2
196
197The above example would force the tuner to the PAL B/G TV band and receive
198stereo audio broadcasts on the A2 carrier.
199
200To verify that the configuration has been placed in the correct location,
201execute:
202
203 $ modprobe -c | grep wis-sony-tuner
204
205If the configuration line appears, then modprobe will pass the parameters
206correctly the next time the wis-sony-tuner module is loaded into the
207kernel.
208
209
210 4. TESTING THE DRIVER
211
212
213Because few Linux applications are able to correctly capture from
214Video4Linux2 devices with only compressed formats supported, the new driver
215should be tested with the "gorecord" application in the apps/ directory.
216
217First connect a video source to the device, such as a DVD player or VCR.
218This will be captured to a file for testing the driver. If an input source
219is unavailable, a test file can still be captured, but the video will be
220black and the audio will be silent.
221
222This application will auto-detect the V4L2 and ALSA/OSS device names of the
223hardware and will record video and audio to an AVI file for a specified
224number of seconds. For example:
225
226 $ apps/gorecord -duration 60 capture.avi
227
228If this application does not successfully record an AVI file, the error
229messages produced by gorecord and recorded in the system log (usually in
230/var/log/messages) should provide information to help resolve the problem.
231
232Supplying no parameters to gorecord will cause it to probe the available
233devices and exit. Use the -help flag for usage information.
234
235
236 5. USING THE DRIVER
237
238
239The V4L2 device implemented by the driver provides a standard compressed
240format 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
266The include/ directory contains a C header file describing non-standard
267features 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
344 Choices are:
345 GO7007_MPEG_VIDEO_MPEG1
346 GO7007_MPEG_VIDEO_MPEG2
347 GO7007_MPEG_VIDEO_MPEG4
348
349 __u32 Bit-wise OR of control flags (below)
350 flags
351
352 __u32 The profile and level indication to be
353 pali stored in the sequence header. This
354 is only used as an indicator to the
355 decoder, and does not affect the MPEG
356 features used in the video stream.
357 Not valid for MPEG1.
358
359 Choices for MPEG2 are:
360 GO7007_MPEG2_PROFILE_MAIN_MAIN
361
362 Choices for MPEG4 are:
363 GO7007_MPEG4_PROFILE_S_L0
364 GO7007_MPEG4_PROFILE_S_L1
365 GO7007_MPEG4_PROFILE_S_L2
366 GO7007_MPEG4_PROFILE_S_L3
367 GO7007_MPEG4_PROFILE_ARTS_L1
368 GO7007_MPEG4_PROFILE_ARTS_L2
369 GO7007_MPEG4_PROFILE_ARTS_L3
370 GO7007_MPEG4_PROFILE_ARTS_L4
371 GO7007_MPEG4_PROFILE_AS_L0
372 GO7007_MPEG4_PROFILE_AS_L1
373 GO7007_MPEG4_PROFILE_AS_L2
374 GO7007_MPEG4_PROFILE_AS_L3
375 GO7007_MPEG4_PROFILE_AS_L4
376 GO7007_MPEG4_PROFILE_AS_L5
377
378 Flags in struct go7007_mpeg_params:
379
380 GO7007_MPEG_FORCE_DVD_MODE Force all compression parameters and
381 bitrate control settings to comply
382 with DVD MPEG2 stream requirements.
383 This overrides most compression and
384 bitrate settings!
385
386 GO7007_MPEG_OMIT_GOP_HEADER Omit the GOP header.
387
388 GO7007_MPEG_REPEAT_SEQHEADER Repeat the MPEG sequence header at
389 the start of each GOP.
390
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.
404
405
406----------------------------------------------------------------------------
407 Installing the WIS PCI Voyager Driver
408---------------------------------------------------------------------------
409
410The WIS PCI Voyager driver requires several patches to the Linux 2.6.11.x
411kernel source tree before compiling the driver. These patches update the
412in-kernel SAA7134 driver to the newest development version and patch bugs
413in the TDA8290/TDA8275 tuner driver.
414
415The following patches must be downloaded from Gerd Knorr's website and
416applied 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
423The following patches are included with this SDK and can be applied in any
424order:
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
430Check to make sure the CONFIG_VIDEO_SAA7134 option is enabled in the kernel
431configuration, and build and install the kernel.
432
433After rebooting into the new kernel, the GO7007 driver can be compiled and
434installed:
435
436 $ make SAA7134_BUILD=y
437 $ make install
438 $ modprobe saa7134-go7007
439
440There will be two V4L video devices associated with the PCI Voyager. The
441first device (most likely /dev/video0) provides access to the raw video
442capture mode of the SAA7133 device and is used to configure the source
443video parameters and tune the TV tuner. This device can be used with xawtv
444or other V4L(2) video software as a standard uncompressed device.
445
446The second device (most likely /dev/video1) provides access to the
447compression functions of the GO7007. It can be tested using the gorecord
448application in the apps/ directory of this SDK:
449
450 $ apps/gorecord -vdevice /dev/video1 -noaudio test.avi
451
452Currently the frame resolution is fixed at 720x480 (NTSC) or 720x576 (PAL),
453and the video standard must be specified to both the raw and the compressed
454video devices (xawtv and gorecord, for example).

457--------------------------------------------------------------------------
458RELEASE NOTES FOR WIS GO7007SB LINUX DRIVER
459---------------------------------------------------------------------------
460
461Last 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.
