7.18. The saa7134 driver¶
Author Gerd Hoffmann
This is a v4l2/oss device driver for saa7130/33/34/35 based capture / TV boards.
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.
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
7.18.3. Changes / Fixes¶
Please mail to linux-media AT vger.kernel.org unified diffs against the linux media git tree:
This is done by committing a patch at a clone of the git tree and
submitting the patch using
git send-email. Don’t forget to
describe at the lots what it changes / which problem it fixes / whatever
it is good for …
7.18.4. 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.
