7.18. The saa7134 driver¶

Author Gerd Hoffmann

This is a v4l2/oss device driver for saa7130/33/34/35 based capture / TV boards.

7.18.1. 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.

7.18.2. 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 SAA7134 cards list 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:

https://git.linuxtv.org/media_tree.git/

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.
