| 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. | |
