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. 57 - 58 - MICRONAS USA, INC., MAKES NO WARRANTIES TO ANY PERSON OR ENTITY WITH 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_MODULES - Enable loadable module support 82 - CONFIG_FW_LOADER - Hotplug firmware loading support 83 - CONFIG_I2C - I2C support 84 - CONFIG_VIDEO_DEV - Video For Linux 85 - CONFIG_SOUND - Sound card support 86 - CONFIG_SND - Advanced Linux Sound Architecture 87 - CONFIG_USB - Support for Host-side USB 88 - CONFIG_USB_EHCI_HCD - EHCI HCD (USB 2.0) support 89 - 90 - Additionally, to use the example application, the following options need to 91 - be enabled in the ALSA section: 92 - 93 - CONFIG_SND_MIXER_OSS - OSS Mixer API 94 - CONFIG_SND_PCM_OSS - OSS PCM (digital audio) API 95 - 96 - The hotplug scripts, along with the fxload utility, must also be installed. 97 - These scripts can be obtained from <http://linux-hotplug.sourceforge.net/>. 98 - Hotplugging is used for loading firmware into the Cypruss EZ-USB chip using 99 - fxload and for loading firmware into the driver using the firmware agent. 100 - 101 - 102 - 2. COMPILING AND INSTALLING THE DRIVER 103 - 104 - 105 - Most users should be able to compile the driver by simply running: 106 - 107 - $ make 108 - 109 - in the top-level directory of the driver kit. First the kernel modules 110 - will be built, followed by the example applications. 111 - 112 - If the build system is unable to locate the kernel source tree for the 113 - currently-running kernel, or if the module should be built for a kernel 114 - other than the currently-running kernel, an additional parameter will need 115 - to be passed to make to specify the appropriate kernel source directory: 116 - 117 - $ make KERNELSRC=/usr/src/linux-2.6.10-custom3 118 - 119 - Once the compile completes, the driver and firmware files should be 120 - installed by running: 121 - 122 - $ make install 123 - 124 - The kernel modules will be placed in "/lib/modules/<KERNEL VERSION>/extra" 125 - and the firmware files will be placed in the appropriate hotplug firmware 126 - directory, usually /lib/firmware. In addition, USB maps and scripts will 127 - be placed in /etc/hotplug/usb to enable fxload to initialize the EZ-USB 128 - control chip when the device is connected. 129 - 130 - 131 - 3. PAL/SECAM TUNER CONFIGURATION (TV402U-EU only) 132 - 133 - 134 - The PAL model of the Plextor ConvertX TV402U may require additional 135 - configuration to correctly select the appropriate TV frequency band and 136 - audio subchannel. 137 - 138 - Users with a device other than the Plextor ConvertX TV402U-EU should skip 139 - this section. 140 - 141 - The wide variety of PAL TV systems used in Europe requires that additional 142 - information about the local TV standards be passed to the driver in order 143 - to properly tune TV channels. The two necessary parameters are (a) the PAL 144 - TV band, and (b) the audio subchannel format in use. 145 - 146 - In many cases, the appropriate TV band selection is passed to the driver 147 - from applications. However, in some cases, the application only specifies 148 - that the driver should use PAL but not the specific information about the 149 - appropriate TV band. To work around this issue, the correct TV band may be 150 - specified in the "force_band" parameter to the wis-sony-tuner module: 151 - 152 - TV band force_band 153 - ------- ---------- 154 - PAL B/G B 155 - PAL I I 156 - PAL D/K D 157 - SECAM L L 158 - 159 - If the "force_band" parameter is specified, the driver will ignore any TV 160 - band specified by applications and will always use the band provided in the 161 - module parameter. 162 - 163 - The other parameter that can be specified is the audio subchannel format. 164 - There are several stereo audio carrier systems in use, including NICAM and 165 - three varieties of A2. To receive audio broadcast on one of these stereo 166 - carriers, the "force_mpx_mode" parameter must be specified to the 167 - wis-sony-tuner module. 168 - 169 - TV band Audio subcarrier force_mpx_mode 170 - ------- ---------------- -------------- 171 - PAL B/G Mono (default) 1 172 - PAL B/G A2 2 173 - PAL B/G NICAM 3 174 - PAL I Mono (default) 4 175 - PAL I NICAM 5 176 - PAL D/K Mono (default) 6 177 - PAL D/K A2 (1) 7 178 - PAL D/K A2 (2) 8 179 - PAL D/K A2 (3) 9 180 - PAL D/K NICAM 10 181 - SECAM L Mono (default) 11 182 - SECAM L NICAM 12 183 - 184 - If the "force_mpx_mode" parameter is not specified, the correct mono-only 185 - mode will be chosen based on the TV band. However, the tuner will not 186 - receive stereo audio or bilingual broadcasts correctly. 187 - 188 - To pass the "force_band" or "force_mpx_mode" parameters to the 189 - wis-sony-tuner module, the following line must be added to the modprobe 190 - configuration file, which varies from one Linux distribution to another. 191 - 192 - options wis-sony-tuner force_band=B force_mpx_mode=2 193 - 194 - The above example would force the tuner to the PAL B/G TV band and receive 195 - stereo audio broadcasts on the A2 carrier. 196 - 197 - To verify that the configuration has been placed in the correct location, 198 - execute: 199 - 200 - $ modprobe -c | grep wis-sony-tuner 201 - 202 - If the configuration line appears, then modprobe will pass the parameters 203 - correctly the next time the wis-sony-tuner module is loaded into the 204 - kernel. 205 - 206 - 207 - 4. TESTING THE DRIVER 208 - 209 - 210 - Because few Linux applications are able to correctly capture from 211 - Video4Linux2 devices with only compressed formats supported, the new driver 212 - should be tested with the "gorecord" application in the apps/ directory. 213 - 214 - First connect a video source to the device, such as a DVD player or VCR. 215 - This will be captured to a file for testing the driver. If an input source 216 - is unavailable, a test file can still be captured, but the video will be 217 - black and the audio will be silent. 218 - 219 - This application will auto-detect the V4L2 and ALSA/OSS device names of the 220 - hardware and will record video and audio to an AVI file for a specified 221 - number of seconds. For example: 222 - 223 - $ apps/gorecord -duration 60 capture.avi 224 - 225 - If this application does not successfully record an AVI file, the error 226 - messages produced by gorecord and recorded in the system log (usually in 227 - /var/log/messages) should provide information to help resolve the problem. 228 - 229 - Supplying no parameters to gorecord will cause it to probe the available 230 - devices and exit. Use the -help flag for usage information. 231 - 232 - 233 - 5. USING THE DRIVER 234 - 235 - 236 - The V4L2 device implemented by the driver provides a standard compressed 237 - format API, within the following criteria: 238 - 239 - * Applications that only support the original Video4Linux1 API will not 240 - be able to communicate with this driver at all. 241 - 242 - * No raw video modes are supported, so applications like xawtv that 243 - expect only uncompressed video will not function. 244 - 245 - * Supported compression formats are: Motion-JPEG, MPEG1, MPEG2 and MPEG4. 246 - 247 - * MPEG video formats are delivered as Video Elementary Streams only. 248 - Program Stream (PS), Transport Stream (TS) and Packetized Elementary 249 - Stream (PES) formats are not supported. 250 - 251 - * Video parameters such as format and input port may not be changed while 252 - the encoder is active. 253 - 254 - * The audio capture device only functions when the video encoder is 255 - actively capturing video. Attempts to read from the audio device when 256 - the encoder is inactive will result in an I/O error. 257 - 258 - * The native format of the audio device is 48Khz 2-channel 16-bit 259 - little-endian PCM, delivered through the ALSA system. No audio 260 - compression is implemented in the hardware. ALSA may convert to other 261 - uncompressed formats on the fly. 262 - 263 - The include/ directory contains a C header file describing non-standard 264 - features of the GO7007SB encoder, which are described below: 265 - 266 - 267 - GO7007IOC_S_COMP_PARAMS, GO7007IOC_G_COMP_PARAMS 268 - 269 - These ioctls are used to negotiate general compression parameters. 270 - 271 - To query the current parameters, call the GO7007IOC_G_COMP_PARAMS ioctl 272 - with a pointer to a struct go7007_comp_params. If the driver is not 273 - set to MPEG format, the EINVAL error code will be returned. 274 - 275 - To change the current parameters, initialize all fields of a struct 276 - go7007_comp_params and call the GO7007_IOC_S_COMP_PARAMS ioctl with a 277 - pointer to this structure.

These patches update the 409 - in-kernel SAA7134 driver to the newest development version and patch bugs 410 - in the TDA8290/TDA8275 tuner driver. 411 - 412 - The following patches must be downloaded from Gerd Knorr's website and 413 - applied in the order listed: 414 - 415 - http://dl.bytesex.org/patches/2.6.11-2/i2c-tuner 416 - http://dl.bytesex.org/patches/2.6.11-2/i2c-tuner2 417 - http://dl.bytesex.org/patches/2.6.11-2/v4l2-api-mpeg 418 - http://dl.bytesex.org/patches/2.6.11-2/saa7134-update 419 - 420 - The following patches are included with this SDK and can be applied in any 421 - order: 422 - 423 - patches/2.6.11/saa7134-voyager.diff 424 - patches/2.6.11/tda8275-newaddr.diff 425 - patches/2.6.11/tda8290-ntsc.diff 426 - 427 - Check to make sure the CONFIG_VIDEO_SAA7134 option is enabled in the kernel 428 - configuration, and build and install the kernel. 429 - 430 - After rebooting into the new kernel, the GO7007 driver can be compiled and 431 - installed: 432 - 433 - $ make SAA7134_BUILD=y 434 - $ make install 435 - $ modprobe saa7134-go7007 436 - 437 - There will be two V4L video devices associated with the PCI Voyager. The 438 - first device (most likely /dev/video0) provides access to the raw video 439 - capture mode of the SAA7133 device and is used to configure the source 440 - video parameters and tune the TV tuner. This device can be used with xawtv 441 - or other V4L(2) video software as a standard uncompressed device. 442 - 443 - The second device (most likely /dev/video1) provides access to the 444 - compression functions of the GO7007. It can be tested using the gorecord 445 - application in the apps/ directory of this SDK: 446 - 447 - $ apps/gorecord -vdevice /dev/video1 -noaudio test.avi 448 - 449 - Currently the frame resolution is fixed at 720x480 (NTSC) or 720x576 (PAL), 450 - and the video standard must be specified to both the raw and the compressed 451 - video devices (xawtv and gorecord, for example). 452 - 453 - 454 - -------------------------------------------------------------------------- 455 - RELEASE NOTES FOR WIS GO7007SB LINUX DRIVER 456 - --------------------------------------------------------------------------- 457 - 458 - Last updated: 5 November 2005 459 - 460 - - Release 0.9.7 includes new support for using udev to run fxload. The 461 - install script should automatically detect whether the old hotplug 462 - scripts or the new udev rules should be used. To force the use of 463 - hotplug, run "make install USE_UDEV=n". To force the use of udev, run 464 - "make install USE_UDEV=y". 465 - 466 - - Motion detection is supported but undocumented. Try the `modet` app 467 - for a demonstration of how to use the facility. 468 - 469 - - Using USB2.0 devices such as the TV402U with USB1.1 HCDs or hubs can 470 - cause buffer overruns and frame drops, even at low framerates, due to 471 - inconsistency in the bitrate control mechanism. 472 - 473 - - On devices with an SAA7115, including the Plextor ConvertX, video height 474 - values of 96, 128, 160, 192, 256, 320, and 384 do not work in NTSC mode. 475 - All valid heights up to 512 work correctly in PAL mode. 476 - 477 - - The WIS Star Trek and PCI Voyager boards have no support yet for audio 478 - or the TV tuner.
