| 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. |
