From 8f33450a4c886774345d606d615cf6b50fa193b7 Mon Sep 17 00:00:00 2001 From: Ian Armstrong Date: Mon, 24 Oct 2011 00:41:27 +0100 Subject: [media] ivtv: Fix radio support Although the ivtv driver reports radio support through the V4L2 API, it fails to actually enable it. This patch fixes that.

This driver requires firmware (which Abilis has provided with redistribution terms which will allow it to be bundled in the Linux distributions). The firmware can be downloaded from here: Thanks to Rainer Miethling from PCTV Systems for working to get the driver released (for use with the PCTV 74e) and Pierrick Hascoet from Abilis for authoring the driver.

Note that the product name field has not yet been abstracted out, so it will still identify itself as a PCTV 74e. The driver was originally built by the chipset manufacturer so that the product vendor can specify the device name via a #define, but wasn't setup to support multiple products from the same build of the driver.

Better to distinguish it, by putting the media drivers at a separate staging directory. Newer staging drivers that include anything with "dvb*.h", "v4l2*.h" or "videodev2.h" should go to the drivers/staging/media tree.

These pseudo-standards are named: - - PAL_BGHIN_SLOW, NTSC_N_443_SLOW, - PAL_Nc_SLOW, NTSC_N_SLOW, - SECAM_SLOW, NTSC_M_SLOW, NTSC_M_JP_SLOW, - PAL_60_SLOW, NTSC_443_SLOW, - PAL_M_SLOW. - - -The available picture sizes are: - - at 25 frames per second: 720x576, 704x576, 640x480, 360x288, 320x240; - at 30 frames per second: 720x480, 640x480, 360x240, 320x240. - - -WHAT'S TESTED AND WHAT'S NOT ----------------------------- - -This driver is known to work with mplayer, mencoder, tvtime, zoneminder, -xawtv, gstreamer and sufficiently recent versions of vlc.

OVERVIEW AND LICENSING/DISCLAIMER - - -This driver kit contains Linux drivers for the WIS GO7007SB multi-format -video encoder. Only kernel version 2.6.x is supported. The video stream -is available through the Video4Linux2 API and the audio stream is available -through the ALSA API (or the OSS emulation layer of the ALSA system). - -The files in kernel/ and hotplug/ are licensed under the GNU General Public -License Version 2 from the Free Software Foundation. A copy of the license -is included in the file COPYING. - -The example applications in apps/ and C header files in include/ are -licensed under a permissive license included in the source files which -allows copying, modification and redistribution for any purpose without -attribution. - -The firmware files included in the firmware/ directory may be freely -redistributed only in conjunction with this document; but modification, -tampering and reverse engineering are prohibited. - -MICRONAS USA, INC., MAKES NO WARRANTIES TO ANY PERSON OR ENTITY WITH -RESPECT TO THE SOFTWARE OR ANY DERIVATIVES THEREOF OR ANY SERVICES OR -LICENSES AND DISCLAIMS ALL IMPLIED WARRANTIES, INCLUDING WITHOUT LIMITATION -WARRANTIES OF MERCHANTABILITY, SUPPORT, AND FITNESS FOR A PARTICULAR -PURPOSE AND NON-INFRINGEMENT. - - - 1. SYSTEM REQUIREMENTS - - -This driver requires Linux kernel 2.6. Kernel 2.4 is not supported. Using -kernel 2.6.10 or later is recommended, as earlier kernels are known to have -unstable USB 2.0 support. - -A fully built kernel source tree must be available. Typically this will be -linked from "/lib/modules//build" for convenience. If this -link does not exist, an extra parameter will need to be passed to the -`make` command. - -All vendor-built kernels should already be configured properly. However, -for custom-built kernels, the following options need to be enabled in the -kernel as built-in or modules: - - CONFIG_HOTPLUG - Support for hot-pluggable devices - CONFIG_MODULES - Enable loadable module support - CONFIG_KMOD - Automatic kernel module loading - CONFIG_FW_LOADER - Hotplug firmware loading support - CONFIG_I2C - I2C support - CONFIG_VIDEO_DEV - Video For Linux - CONFIG_SOUND - Sound card support - CONFIG_SND - Advanced Linux Sound Architecture - CONFIG_USB - Support for Host-side USB - CONFIG_USB_DEVICEFS - USB device filesystem - CONFIG_USB_EHCI_HCD - EHCI HCD (USB 2.0) support - -Additionally, to use the example application, the following options need to -be enabled in the ALSA section: - - CONFIG_SND_MIXER_OSS - OSS Mixer API - CONFIG_SND_PCM_OSS - OSS PCM (digital audio) API - -The hotplug scripts, along with the fxload utility, must also be installed. -These scripts can be obtained from . -Hotplugging is used for loading firmware into the Cypruss EZ-USB chip using -fxload and for loading firmware into the driver using the firmware agent. - - - 2. COMPILING AND INSTALLING THE DRIVER - - -Most users should be able to compile the driver by simply running: - - $ make - -in the top-level directory of the driver kit. First the kernel modules -will be built, followed by the example applications. - -If the build system is unable to locate the kernel source tree for the -currently-running kernel, or if the module should be built for a kernel -other than the currently-running kernel, an additional parameter will need -to be passed to make to specify the appropriate kernel source directory: - - $ make KERNELSRC=/usr/src/linux-2.6.10-custom3 - -Once the compile completes, the driver and firmware files should be -installed by running: - - $ make install - -The kernel modules will be placed in "/lib/modules//extra" -and the firmware files will be placed in the appropriate hotplug firmware -directory, usually /lib/firmware. In addition, USB maps and scripts will -be placed in /etc/hotplug/usb to enable fxload to initialize the EZ-USB -control chip when the device is connected. - - - 3. PAL/SECAM TUNER CONFIGURATION (TV402U-EU only) - - -The PAL model of the Plextor ConvertX TV402U may require additional -configuration to correctly select the appropriate TV frequency band and -audio subchannel. - -Users with a device other than the Plextor ConvertX TV402U-EU should skip -this section. - -The wide variety of PAL TV systems used in Europe requires that additional -information about the local TV standards be passed to the driver in order -to properly tune TV channels. The two necessary parameters are (a) the PAL -TV band, and (b) the audio subchannel format in use. - -In many cases, the appropriate TV band selection is passed to the driver -from applications. However, in some cases, the application only specifies -that the driver should use PAL but not the specific information about the -appropriate TV band. To work around this issue, the correct TV band may be -specified in the "force_band" parameter to the wis-sony-tuner module: - - TV band force_band - ------- ---------- - PAL B/G B - PAL I I - PAL D/K D - SECAM L L - -If the "force_band" parameter is specified, the driver will ignore any TV -band specified by applications and will always use the band provided in the -module parameter. - -The other parameter that can be specified is the audio subchannel format. -There are several stereo audio carrier systems in use, including NICAM and -three varieties of A2. To receive audio broadcast on one of these stereo -carriers, the "force_mpx_mode" parameter must be specified to the -wis-sony-tuner module. - - TV band Audio subcarrier force_mpx_mode - ------- ---------------- -------------- - PAL B/G Mono (default) 1 - PAL B/G A2 2 - PAL B/G NICAM 3 - PAL I Mono (default) 4 - PAL I NICAM 5 - PAL D/K Mono (default) 6 - PAL D/K A2 (1) 7 - PAL D/K A2 (2) 8 - PAL D/K A2 (3) 9 - PAL D/K NICAM 10 - SECAM L Mono (default) 11 - SECAM L NICAM 12 - -If the "force_mpx_mode" parameter is not specified, the correct mono-only -mode will be chosen based on the TV band. However, the tuner will not -receive stereo audio or bilingual broadcasts correctly. - -To pass the "force_band" or "force_mpx_mode" parameters to the -wis-sony-tuner module, the following line must be added to the modprobe -configuration file, which varies from one Linux distribution to another. - - options wis-sony-tuner force_band=B force_mpx_mode=2 - -The above example would force the tuner to the PAL B/G TV band and receive -stereo audio broadcasts on the A2 carrier. - -To verify that the configuration has been placed in the correct location, -execute: - - $ modprobe -c | grep wis-sony-tuner - -If the configuration line appears, then modprobe will pass the parameters -correctly the next time the wis-sony-tuner module is loaded into the -kernel. - - - 4. TESTING THE DRIVER - - -Because few Linux applications are able to correctly capture from -Video4Linux2 devices with only compressed formats supported, the new driver -should be tested with the "gorecord" application in the apps/ directory. - -First connect a video source to the device, such as a DVD player or VCR. -This will be captured to a file for testing the driver. If an input source -is unavailable, a test file can still be captured, but the video will be -black and the audio will be silent. - -This application will auto-detect the V4L2 and ALSA/OSS device names of the -hardware and will record video and audio to an AVI file for a specified -number of seconds. For example: - - $ apps/gorecord -duration 60 capture.avi - -If this application does not successfully record an AVI file, the error -messages produced by gorecord and recorded in the system log (usually in -/var/log/messages) should provide information to help resolve the problem. - -Supplying no parameters to gorecord will cause it to probe the available -devices and exit. Use the -help flag for usage information. - - - 5. USING THE DRIVER - - -The V4L2 device implemented by the driver provides a standard compressed -format API, within the following criteria: - - * Applications that only support the original Video4Linux1 API will not - be able to communicate with this driver at all. - - * No raw video modes are supported, so applications like xawtv that - expect only uncompressed video will not function. - - * Supported compression formats are: Motion-JPEG, MPEG1, MPEG2 and MPEG4. - - * MPEG video formats are delivered as Video Elementary Streams only. - Program Stream (PS), Transport Stream (TS) and Packetized Elementary - Stream (PES) formats are not supported. - - * Video parameters such as format and input port may not be changed while - the encoder is active. - - * The audio capture device only functions when the video encoder is - actively capturing video. Attempts to read from the audio device when - the encoder is inactive will result in an I/O error. - - * The native format of the audio device is 48Khz 2-channel 16-bit - little-endian PCM, delivered through the ALSA system. No audio - compression is implemented in the hardware. ALSA may convert to other - uncompressed formats on the fly. - -The include/ directory contains a C header file describing non-standard -features of the GO7007SB encoder, which are described below: - - - GO7007IOC_S_COMP_PARAMS, GO7007IOC_G_COMP_PARAMS - - These ioctls are used to negotiate general compression parameters. - - To query the current parameters, call the GO7007IOC_G_COMP_PARAMS ioctl - with a pointer to a struct go7007_comp_params. If the driver is not - set to MPEG format, the EINVAL error code will be returned. - - To change the current parameters, initialize all fields of a struct - go7007_comp_params and call the GO7007_IOC_S_COMP_PARAMS ioctl with a - pointer to this structure. The driver will return the current - parameters with any necessary changes to conform to the limitations of - the hardware or current compression mode. Any or all fields can be set - to zero to request a reasonable default value. If the driver is not - set to MPEG format, the EINVAL error code will be returned. When I/O - is in progress, the EBUSY error code will be returned. - - Fields in struct go7007_comp_params: - - __u32 The maximum number of frames in each - gop_size Group Of Pictures; i.e. the maximum - number of frames minus one between - each key frame. - - __u32 The maximum number of sequential - max_b_frames bidirectionally-predicted frames. - (B-frames are not yet supported.) - - enum go7007_aspect_ratio The aspect ratio to be encoded in the - aspect_ratio meta-data of the compressed format. - - Choices are: - GO7007_ASPECT_RATIO_1_1 - GO7007_ASPECT_RATIO_4_3_NTSC - GO7007_ASPECT_RATIO_4_3_PAL - GO7007_ASPECT_RATIO_16_9_NTSC - GO7007_ASPECT_RATIO_16_9_PAL - - __u32 Bit-wise OR of control flags (below) - flags - - Flags in struct go7007_comp_params: - - GO7007_COMP_CLOSED_GOP Only produce self-contained GOPs, used - to produce streams appropriate for - random seeking. - - GO7007_COMP_OMIT_SEQ_HEADER Omit the stream sequence header. - - - GO7007IOC_S_MPEG_PARAMS, GO7007IOC_G_MPEG_PARAMS - - These ioctls are used to negotiate MPEG-specific stream parameters when - the pixelformat has been set to V4L2_PIX_FMT_MPEG. - - To query the current parameters, call the GO7007IOC_G_MPEG_PARAMS ioctl - with a pointer to a struct go7007_mpeg_params. If the driver is not - set to MPEG format, the EINVAL error code will be returned. - - To change the current parameters, initialize all fields of a struct - go7007_mpeg_params and call the GO7007_IOC_S_MPEG_PARAMS ioctl with a - pointer to this structure. The driver will return the current - parameters with any necessary changes to conform to the limitations of - the hardware or selected MPEG mode. Any or all fields can be set to - zero to request a reasonable default value. If the driver is not set - to MPEG format, the EINVAL error code will be returned. When I/O is in - progress, the EBUSY error code will be returned. - - Fields in struct go7007_mpeg_params: - - enum go7007_mpeg_video_standard - mpeg_video_standard The MPEG video standard in which to - compress the video. - - Choices are: - GO7007_MPEG_VIDEO_MPEG1 - GO7007_MPEG_VIDEO_MPEG2 - GO7007_MPEG_VIDEO_MPEG4 - - __u32 Bit-wise OR of control flags (below) - flags - - __u32 The profile and level indication to be - pali stored in the sequence header. This - is only used as an indicator to the - decoder, and does not affect the MPEG - features used in the video stream. - Not valid for MPEG1. - - Choices for MPEG2 are: - GO7007_MPEG2_PROFILE_MAIN_MAIN - - Choices for MPEG4 are: - GO7007_MPEG4_PROFILE_S_L0 - GO7007_MPEG4_PROFILE_S_L1 - GO7007_MPEG4_PROFILE_S_L2 - GO7007_MPEG4_PROFILE_S_L3 - GO7007_MPEG4_PROFILE_ARTS_L1 - GO7007_MPEG4_PROFILE_ARTS_L2 - GO7007_MPEG4_PROFILE_ARTS_L3 - GO7007_MPEG4_PROFILE_ARTS_L4 - GO7007_MPEG4_PROFILE_AS_L0 - GO7007_MPEG4_PROFILE_AS_L1 - GO7007_MPEG4_PROFILE_AS_L2 - GO7007_MPEG4_PROFILE_AS_L3 - GO7007_MPEG4_PROFILE_AS_L4 - GO7007_MPEG4_PROFILE_AS_L5 - - Flags in struct go7007_mpeg_params: - - GO7007_MPEG_FORCE_DVD_MODE Force all compression parameters and - bitrate control settings to comply - with DVD MPEG2 stream requirements. - This overrides most compression and - bitrate settings! - - GO7007_MPEG_OMIT_GOP_HEADER Omit the GOP header. - - GO7007_MPEG_REPEAT_SEQHEADER Repeat the MPEG sequence header at - the start of each GOP. - - - GO7007IOC_S_BITRATE, GO7007IOC_G_BITRATE - - These ioctls are used to set and query the target bitrate value for the - compressed video stream. The bitrate may be selected by storing the - target bits per second in an int and calling GO7007IOC_S_BITRATE with a - pointer to the int. The bitrate may be queried by calling - GO7007IOC_G_BITRATE with a pointer to an int where the current bitrate - will be stored. - - Note that this is the primary means of controlling the video quality - for all compression modes, including V4L2_PIX_FMT_MJPEG. The - VIDIOC_S_JPEGCOMP ioctl is not supported. - - ----------------------------------------------------------------------------- - Installing the WIS PCI Voyager Driver ---------------------------------------------------------------------------- - -The WIS PCI Voyager driver requires several patches to the Linux 2.6.11.x -kernel source tree before compiling the driver. These patches update the -in-kernel SAA7134 driver to the newest development version and patch bugs -in the TDA8290/TDA8275 tuner driver. - -The following patches must be downloaded from Gerd Knorr's website and -applied in the order listed: - - http://dl.bytesex.org/patches/2.6.11-2/i2c-tuner - http://dl.bytesex.org/patches/2.6.11-2/i2c-tuner2 - http://dl.bytesex.org/patches/2.6.11-2/v4l2-api-mpeg - http://dl.bytesex.org/patches/2.6.11-2/saa7134-update - -The following patches are included with this SDK and can be applied in any -order: - - patches/2.6.11/saa7134-voyager.diff - patches/2.6.11/tda8275-newaddr.diff - patches/2.6.11/tda8290-ntsc.diff - -Check to make sure the CONFIG_VIDEO_SAA7134 option is enabled in the kernel -configuration, and build and install the kernel. - -After rebooting into the new kernel, the GO7007 driver can be compiled and -installed: - - $ make SAA7134_BUILD=y - $ make install - $ modprobe saa7134-go7007 - -There will be two V4L video devices associated with the PCI Voyager. The -first device (most likely /dev/video0) provides access to the raw video -capture mode of the SAA7133 device and is used to configure the source -video parameters and tune the TV tuner. This device can be used with xawtv -or other V4L(2) video software as a standard uncompressed device. - -The second device (most likely /dev/video1) provides access to the -compression functions of the GO7007. It can be tested using the gorecord -application in the apps/ directory of this SDK: - - $ apps/gorecord -vdevice /dev/video1 -noaudio test.avi - -Currently the frame resolution is fixed at 720x480 (NTSC) or 720x576 (PAL), -and the video standard must be specified to both the raw and the compressed -video devices (xawtv and gorecord, for example). - - --------------------------------------------------------------------------- -RELEASE NOTES FOR WIS GO7007SB LINUX DRIVER ---------------------------------------------------------------------------- - -Last updated: 5 November 2005 - - - Release 0.9.7 includes new support for using udev to run fxload. The - install script should automatically detect whether the old hotplug - scripts or the new udev rules should be used. To force the use of - hotplug, run "make install USE_UDEV=n". To force the use of udev, run - "make install USE_UDEV=y". - - - Motion detection is supported but undocumented.

This is not strictly needed, so it -is not required to move lirc_zilog out of staging. - -Note: Both lirc_zilog and ir-kbd-i2c support the Zilog Z8 for IR, as programmed -and installed on Hauppauge products. When working on either module, developers -must consider at least the following bridge drivers which mention an IR Rx unit -at address 0x71 (indicative of a Z8): - - ivtv cx18 hdpvr pvrusb2 bt8xx cx88 saa7134 - diff --git a/drivers/staging/lirc/lirc_bt829.c b/drivers/staging/lirc/lirc_bt829.c deleted file mode 100644 index c5a0d27a02dc..000000000000 --- a/drivers/staging/lirc/lirc_bt829.c +++ /dev/null @@ -1,383 +0,0 @@ -/* - * Remote control driver for the TV-card based on bt829 - * - * by Leonid Froenchenko - * - * This program is free software; you can redistribute it and/or modify - * it under the terms of the GNU General Public License as published by - * the Free Software Foundation; either version 2 of the License, or - * (at your option) any later version. - * - * This program is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Normal video output will be +present for about a minute but will then freeze when this situation arises. + +(2) The controls for luminance, contrast, saturation, hue and volume may not +always work properly. + +(3) Reduced-resolution S-Video seems to suffer from moire artefacts. + + +INPUT NUMBERING +--------------- + +For the EasyCAP with S-VIDEO input cable the driver regards a request for +inputs numbered 0 or 1 as referring to CVBS and a request for input +numbered 5 as referring to S-VIDEO. + +For the EasyCAP with four CVBS inputs the driver expects to be asked for +any one of inputs numbered 1,2,3,4. If input 0 is asked for, it is +interpreted as input 1. + + +MODULE PARAMETERS +----------------- + +Three module parameters are defined: + +debug the easycap module is configured at diagnostic level n (0 to 9) +gain audio gain level n (0 to 31, default is 16) +bars whether to display testcard bars when incoming video signal is lost + 0 => no, 1 => yes (default) + + +SUPPORTED TV STANDARDS AND RESOLUTIONS +-------------------------------------- + +The following TV standards are natively supported by the hardware and are +usable as (for example) the "norm=" parameter in the mplayer command: + + PAL_BGHIN, NTSC_N_443, + PAL_Nc, NTSC_N, + SECAM, NTSC_M, NTSC_M_JP, + PAL_60, NTSC_443, + PAL_M. + +In addition, the driver offers "custom" pseudo-standards with a framerate +which is 20% of the usual framerate. These pseudo-standards are named: + + PAL_BGHIN_SLOW, NTSC_N_443_SLOW, + PAL_Nc_SLOW, NTSC_N_SLOW, + SECAM_SLOW, NTSC_M_SLOW, NTSC_M_JP_SLOW, + PAL_60_SLOW, NTSC_443_SLOW, + PAL_M_SLOW. + + +The available picture sizes are: + + at 25 frames per second: 720x576, 704x576, 640x480, 360x288, 320x240; + at 30 frames per second: 720x480, 640x480, 360x240, 320x240. + + +WHAT'S TESTED AND WHAT'S NOT +---------------------------- + +This driver is known to work with mplayer, mencoder, tvtime, zoneminder, +xawtv, gstreamer and sufficiently recent versions of vlc. An interface +to ffmpeg is implemented, but serious audio-video synchronization problems +remain. + +The driver is designed to support all the TV standards accepted by the +hardware, but as yet it has actually been tested on only a few of these. + +I have been unable to test and calibrate the S-video input myself because I +do not possess any equipment with S-video output. + + +UDEV RULES +---------- + +In order that the special files /dev/easycap0 and /dev/easysnd1 are created +with conveniently relaxed permissions when the EasyCAP is plugged in, a file +is preferably to be provided in directory /etc/udev/rules.d with content: + +ACTION!="add|change", GOTO="easycap_rules_end" +ATTRS{idVendor}=="05e1", ATTRS{idProduct}=="0408", \ + MODE="0666", OWNER="root", GROUP="root" +LABEL="easycap_rules_end" + + +MODPROBE CONFIGURATION +---------------------- + +The easycap module is in competition with the module snd-usb-audio for the +EasyCAP's audio channel, and its installation can be aided by providing a +file in directory /etc/modprobe.d with content: + +options easycap gain=16 bars=1 +install easycap /sbin/rmmod snd-usb-audio; /sbin/modprobe --ignore-install easycap + + +ACKNOWLEGEMENTS AND REFERENCES +------------------------------ +This driver makes use of information contained in the Syntek Semicon DC-1125 +Driver, presently maintained at http://sourceforge.net/projects/syntekdriver/ +by Nicolas Vivien.

OVERVIEW AND LICENSING/DISCLAIMER + + +This driver kit contains Linux drivers for the WIS GO7007SB multi-format +video encoder. Only kernel version 2.6.x is supported. The video stream +is available through the Video4Linux2 API and the audio stream is available +through the ALSA API (or the OSS emulation layer of the ALSA system). + +The files in kernel/ and hotplug/ are licensed under the GNU General Public +License Version 2 from the Free Software Foundation. A copy of the license +is included in the file COPYING. + +The example applications in apps/ and C header files in include/ are +licensed under a permissive license included in the source files which +allows copying, modification and redistribution for any purpose without +attribution. + +The firmware files included in the firmware/ directory may be freely +redistributed only in conjunction with this document; but modification, +tampering and reverse engineering are prohibited. + +MICRONAS USA, INC., MAKES NO WARRANTIES TO ANY PERSON OR ENTITY WITH +RESPECT TO THE SOFTWARE OR ANY DERIVATIVES THEREOF OR ANY SERVICES OR +LICENSES AND DISCLAIMS ALL IMPLIED WARRANTIES, INCLUDING WITHOUT LIMITATION +WARRANTIES OF MERCHANTABILITY, SUPPORT, AND FITNESS FOR A PARTICULAR +PURPOSE AND NON-INFRINGEMENT. + + + 1. SYSTEM REQUIREMENTS + + +This driver requires Linux kernel 2.6. Kernel 2.4 is not supported. Using +kernel 2.6.10 or later is recommended, as earlier kernels are known to have +unstable USB 2.0 support. + +A fully built kernel source tree must be available. Typically this will be +linked from "/lib/modules//build" for convenience. If this +link does not exist, an extra parameter will need to be passed to the +`make` command. + +All vendor-built kernels should already be configured properly. However, +for custom-built kernels, the following options need to be enabled in the +kernel as built-in or modules: + + CONFIG_HOTPLUG - Support for hot-pluggable devices + CONFIG_MODULES - Enable loadable module support + CONFIG_KMOD - Automatic kernel module loading + CONFIG_FW_LOADER - Hotplug firmware loading support + CONFIG_I2C - I2C support + CONFIG_VIDEO_DEV - Video For Linux + CONFIG_SOUND - Sound card support + CONFIG_SND - Advanced Linux Sound Architecture + CONFIG_USB - Support for Host-side USB + CONFIG_USB_DEVICEFS - USB device filesystem + CONFIG_USB_EHCI_HCD - EHCI HCD (USB 2.0) support + +Additionally, to use the example application, the following options need to +be enabled in the ALSA section: + + CONFIG_SND_MIXER_OSS - OSS Mixer API + CONFIG_SND_PCM_OSS - OSS PCM (digital audio) API + +The hotplug scripts, along with the fxload utility, must also be installed. +These scripts can be obtained from . +Hotplugging is used for loading firmware into the Cypruss EZ-USB chip using +fxload and for loading firmware into the driver using the firmware agent. + + + 2. COMPILING AND INSTALLING THE DRIVER + + +Most users should be able to compile the driver by simply running: + + $ make + +in the top-level directory of the driver kit. First the kernel modules +will be built, followed by the example applications. + +If the build system is unable to locate the kernel source tree for the +currently-running kernel, or if the module should be built for a kernel +other than the currently-running kernel, an additional parameter will need +to be passed to make to specify the appropriate kernel source directory: + + $ make KERNELSRC=/usr/src/linux-2.6.10-custom3 + +Once the compile completes, the driver and firmware files should be +installed by running: + + $ make install + +The kernel modules will be placed in "/lib/modules//extra" +and the firmware files will be placed in the appropriate hotplug firmware +directory, usually /lib/firmware. In addition, USB maps and scripts will +be placed in /etc/hotplug/usb to enable fxload to initialize the EZ-USB +control chip when the device is connected. + + + 3. PAL/SECAM TUNER CONFIGURATION (TV402U-EU only) + + +The PAL model of the Plextor ConvertX TV402U may require additional +configuration to correctly select the appropriate TV frequency band and +audio subchannel. + +Users with a device other than the Plextor ConvertX TV402U-EU should skip +this section. + +The wide variety of PAL TV systems used in Europe requires that additional +information about the local TV standards be passed to the driver in order +to properly tune TV channels. The two necessary parameters are (a) the PAL +TV band, and (b) the audio subchannel format in use. + +In many cases, the appropriate TV band selection is passed to the driver +from applications. However, in some cases, the application only specifies +that the driver should use PAL but not the specific information about the +appropriate TV band. To work around this issue, the correct TV band may be +specified in the "force_band" parameter to the wis-sony-tuner module: + + TV band force_band + ------- ---------- + PAL B/G B + PAL I I + PAL D/K D + SECAM L L + +If the "force_band" parameter is specified, the driver will ignore any TV +band specified by applications and will always use the band provided in the +module parameter. + +The other parameter that can be specified is the audio subchannel format. +There are several stereo audio carrier systems in use, including NICAM and +three varieties of A2. To receive audio broadcast on one of these stereo +carriers, the "force_mpx_mode" parameter must be specified to the +wis-sony-tuner module. + + TV band Audio subcarrier force_mpx_mode + ------- ---------------- -------------- + PAL B/G Mono (default) 1 + PAL B/G A2 2 + PAL B/G NICAM 3 + PAL I Mono (default) 4 + PAL I NICAM 5 + PAL D/K Mono (default) 6 + PAL D/K A2 (1) 7 + PAL D/K A2 (2) 8 + PAL D/K A2 (3) 9 + PAL D/K NICAM 10 + SECAM L Mono (default) 11 + SECAM L NICAM 12 + +If the "force_mpx_mode" parameter is not specified, the correct mono-only +mode will be chosen based on the TV band. However, the tuner will not +receive stereo audio or bilingual broadcasts correctly. + +To pass the "force_band" or "force_mpx_mode" parameters to the +wis-sony-tuner module, the following line must be added to the modprobe +configuration file, which varies from one Linux distribution to another. + + options wis-sony-tuner force_band=B force_mpx_mode=2 + +The above example would force the tuner to the PAL B/G TV band and receive +stereo audio broadcasts on the A2 carrier. + +To verify that the configuration has been placed in the correct location, +execute: + + $ modprobe -c | grep wis-sony-tuner + +If the configuration line appears, then modprobe will pass the parameters +correctly the next time the wis-sony-tuner module is loaded into the +kernel. + + + 4. TESTING THE DRIVER + + +Because few Linux applications are able to correctly capture from +Video4Linux2 devices with only compressed formats supported, the new driver +should be tested with the "gorecord" application in the apps/ directory. + +First connect a video source to the device, such as a DVD player or VCR. +This will be captured to a file for testing the driver. If an input source +is unavailable, a test file can still be captured, but the video will be +black and the audio will be silent. + +This application will auto-detect the V4L2 and ALSA/OSS device names of the +hardware and will record video and audio to an AVI file for a specified +number of seconds. For example: + + $ apps/gorecord -duration 60 capture.avi + +If this application does not successfully record an AVI file, the error +messages produced by gorecord and recorded in the system log (usually in +/var/log/messages) should provide information to help resolve the problem. + +Supplying no parameters to gorecord will cause it to probe the available +devices and exit. Use the -help flag for usage information. + + + 5. USING THE DRIVER + + +The V4L2 device implemented by the driver provides a standard compressed +format API, within the following criteria: + + * Applications that only support the original Video4Linux1 API will not + be able to communicate with this driver at all. + + * No raw video modes are supported, so applications like xawtv that + expect only uncompressed video will not function. + + * Supported compression formats are: Motion-JPEG, MPEG1, MPEG2 and MPEG4. + + * MPEG video formats are delivered as Video Elementary Streams only. + Program Stream (PS), Transport Stream (TS) and Packetized Elementary + Stream (PES) formats are not supported. + + * Video parameters such as format and input port may not be changed while + the encoder is active. + + * The audio capture device only functions when the video encoder is + actively capturing video. Attempts to read from the audio device when + the encoder is inactive will result in an I/O error. + + * The native format of the audio device is 48Khz 2-channel 16-bit + little-endian PCM, delivered through the ALSA system. No audio + compression is implemented in the hardware. ALSA may convert to other + uncompressed formats on the fly. + +The include/ directory contains a C header file describing non-standard +features of the GO7007SB encoder, which are described below: + + + GO7007IOC_S_COMP_PARAMS, GO7007IOC_G_COMP_PARAMS + + These ioctls are used to negotiate general compression parameters. + + To query the current parameters, call the GO7007IOC_G_COMP_PARAMS ioctl + with a pointer to a struct go7007_comp_params.

The driver will return the current + parameters with any necessary changes to conform to the limitations of + the hardware or current compression mode. Any or all fields can be set + to zero to request a reasonable default value. If the driver is not + set to MPEG format, the EINVAL error code will be returned.

It can be tested using the gorecord +application in the apps/ directory of this SDK: + + $ apps/gorecord -vdevice /dev/video1 -noaudio test.avi + +Currently the frame resolution is fixed at 720x480 (NTSC) or 720x576 (PAL), +and the video standard must be specified to both the raw and the compressed +video devices (xawtv and gorecord, for example). + + +-------------------------------------------------------------------------- +RELEASE NOTES FOR WIS GO7007SB LINUX DRIVER +--------------------------------------------------------------------------- + +Last updated: 5 November 2005 + + - Release 0.9.7 includes new support for using udev to run fxload. The + install script should automatically detect whether the old hotplug + scripts or the new udev rules should be used. To force the use of + hotplug, run "make install USE_UDEV=n". To force the use of udev, run + "make install USE_UDEV=y". + + - Motion detection is supported but undocumented. Try the `modet` app + for a demonstration of how to use the facility. + + - Using USB2.0 devices such as the TV402U with USB1.1 HCDs or hubs can + cause buffer overruns and frame drops, even at low framerates, due to + inconsistency in the bitrate control mechanism. + + - On devices with an SAA7115, including the Plextor ConvertX, video height + values of 96, 128, 160, 192, 256, 320, and 384 do not work in NTSC mode. + All valid heights up to 512 work correctly in PAL mode. + + - The WIS Star Trek and PCI Voyager boards have no support yet for audio + or the TV tuner. diff --git a/drivers/staging/media/go7007/s2250-board.c b/drivers/staging/media/go7007/s2250-board.c new file mode 100644 index 000000000000..e7736a915530 --- /dev/null +++ b/drivers/staging/media/go7007/s2250-board.c @@ -0,0 +1,698 @@ +/* + * Copyright (C) 2008 Sensoray Company Inc. + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License (Version 2) as + * published by the Free Software Foundation. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

This would allow lirc_zilog +to bring the chip back to normal when it hangs, in the same places the +original lirc_pvr150 driver code does. This is not strictly needed, so it +is not required to move lirc_zilog out of staging. + +Note: Both lirc_zilog and ir-kbd-i2c support the Zilog Z8 for IR, as programmed +and installed on Hauppauge products.

This makes most of the soc-camera client drivers also usable outside of the soc-camera framework. After this change all what is needed for these drivers to function are inclusions of soc-camera headers for some convenience macros, suitably configured platform data, which is anyway always required, and loaded soc-camera core module for library functions. If desired, these library functions can be made generic in the future and moved to a more neutral location. The only two client drivers, that still depend on soc-camera are: mt9t031: it uses struct video_device for its PM. Since no hardware is available, alternative methods cannot be tested. ov6650: it uses struct soc_camera_device to pass its sense data back to the bridge driver. A generic v4l2-subdevice approach should be developed to perform this.
