The saa7134 driver
|
|
==================
|
|
|
|
Author Gerd Hoffmann
|
|
|
|
|
|
This is a v4l2/oss device driver for saa7130/33/34/35 based capture / TV
|
|
boards.
|
|
|
|
|
|
Status
|
|
------
|
|
|
|
Almost everything is working. video, sound, tuner, radio, mpeg ts, ...
|
|
|
|
As with bttv, card-specific tweaks are needed. Check CARDLIST for a
|
|
list of known TV cards and saa7134-cards.c for the drivers card
|
|
configuration info.
|
|
|
|
|
|
Build
|
|
-----
|
|
|
|
Once you pick up a Kernel source, you should configure, build,
|
|
install and boot the new kernel. You'll need at least
|
|
these config options::
|
|
|
|
./scripts/config -e PCI
|
|
./scripts/config -e INPUT
|
|
./scripts/config -m I2C
|
|
./scripts/config -m MEDIA_SUPPORT
|
|
./scripts/config -e MEDIA_PCI_SUPPORT
|
|
./scripts/config -e MEDIA_ANALOG_TV_SUPPORT
|
|
./scripts/config -e MEDIA_DIGITAL_TV_SUPPORT
|
|
./scripts/config -e MEDIA_RADIO_SUPPORT
|
|
./scripts/config -e RC_CORE
|
|
./scripts/config -e MEDIA_SUBDRV_AUTOSELECT
|
|
./scripts/config -m VIDEO_SAA7134
|
|
./scripts/config -e SAA7134_ALSA
|
|
./scripts/config -e VIDEO_SAA7134_RC
|
|
./scripts/config -e VIDEO_SAA7134_DVB
|
|
./scripts/config -e VIDEO_SAA7134_GO7007
|
|
|
|
To build and install, you should run::
|
|
|
|
make && make modules_install && make install
|
|
|
|
Once the new Kernel is booted, saa7134 driver should be loaded automatically.
|
|
|
|
Depending on the card you might have to pass ``card=<nr>`` as insmod option.
|
|
If so, please check Documentation/admin-guide/media/saa7134-cardlist.rst
|
|
for valid choices.
|
|
|
|
Once you have your card type number, you can pass a modules configuration
|
|
via a file (usually, it is either ``/etc/modules.conf`` or some file at
|
|
``/etc/modules-load.d/``, but the actual place depends on your
|
|
distribution), with this content::
|
|
|
|
options saa7134 card=13 # Assuming that your card type is #13
|
|
|
|
|
|

Known Problems
|
|
--------------
|
|
|
|
* The tuner for the flyvideos isn't detected automatically and the
|
|
default might not work for you depending on which version you have.
|
|
There is a ``tuner=`` insmod option to override the driver's default.
