[media] go7007: move out of staging into drivers/media/usb.
Now that the custom motion detection API in this driver has been replaced with a standard API there is no reason anymore to keep it in staging. So (finally!) move it to drivers/media/usb.

Todo:
|
|
||||||
- let s2250-board use i2c subdevs as well instead of hardcoding
|
|
||||||
support for the i2c devices.
|
|
||||||
- when the driver is moved out of staging, support for saa7134-go7007
|
|
||||||
should be added to the saa7134 driver. The patch for that is
|
|
||||||
included below.

Pete Eberlein <pete@sensoray.com>
|

The driver was originally released under the GPL and is currently hosted at:
|
|
||||||
http://nikosapi.org/wiki/index.php/WIS_Go7007_Linux_driver
|
|
||||||
The go7007 firmware can be acquired from the package on the site above.

0. 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

||||||
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/<KERNEL VERSION>/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_MODULES - Enable loadable module support
|
|
||||||
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_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 <http://linux-hotplug.sourceforge.net/>.
|
|
||||||
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/<KERNEL VERSION>/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:
|
|
||||||
|
|

|
|
||||||
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
|
|
||||||

||||||
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
|

|
||||||
|
|
||||||
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. 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.
