- What is it?
- ===========
- This is a v4l2/oss device driver for saa7130/33/34/35 based capture / TV
- boards. See http://www.semiconductors.philips.com/pip/saa7134hl for a
- description.
- 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
- =====
- Pick up videodev + v4l2 patches from http://bytesex.org/patches/.
- Configure, build, install + boot the new kernel. You'll need at least
- these config options:
- CONFIG_I2C=m
- CONFIG_VIDEO_DEV=m
- Type "make" to build the driver now. "make install" installs the
- driver. "modprobe saa7134" should load it. Depending on the card you
- might have to pass card=<nr> as insmod option, check CARDLIST for
- valid choices.
- Changes / Fixes
- ===============
- Please mail me unified diffs ("diff -u") with your changes, and don't
- forget to tell me what it changes / which problem it fixes / whatever
- it is good for ...
- 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.
- Card Variations:
- ================
- Cards can use either of these two crystals (xtal):
- - 32.11 MHz -> .audio_clock=0x187de7
- - 24.576MHz -> .audio_clock=0x200000
- (xtal * .audio_clock = 51539600)
- Some details about 30/34/35:
- - saa7130 - low-price chip, doesn't have mute, that is why all those
- cards should have .mute field defined in their tuner structure.
- - saa7134 - usual chip
- - saa7133/35 - saa7135 is probably a marketing decision, since all those
- chips identifies itself as 33 on pci.
