| 3 | What is it? |
| 4 | =========== |
| 5 | |
| 6 | This is a v4l2/oss device driver for saa7130/33/34/35 based capture / TV |
| 7 | boards. See http://www.semiconductors.philips.com/pip/saa7134hl for a |
| 8 | description. |

| 11 | Status |
| 12 | ====== |
| 13 | |
| 14 | Almost everything is working. video, sound, tuner, radio, mpeg ts, ... |
| 15 | |
| 16 | As with bttv, card-specific tweaks are needed. Check CARDLIST for a |
| 17 | list of known TV cards and saa7134-cards.c for the drivers card |
| 18 | configuration info. |
| 19 | |
| 20 | |
| 21 | Build |
| 22 | ===== |
| 23 | |
| 24 | Pick up videodev + v4l2 patches from http://bytesex.org/patches/. |
| 25 | Configure, build, install + boot the new kernel. You'll need at least |
| 26 | these config options: |
| 27 | |
| 28 | CONFIG_I2C=m |
| 29 | CONFIG_VIDEO_DEV=m |
| 30 | |
| 31 | Type "make" to build the driver now. "make install" installs the |
| 32 | driver. "modprobe saa7134" should load it. Depending on the card you |
| 33 | might have to pass card=<nr> as insmod option, check CARDLIST for |
| 34 | valid choices. |

| 37 | Changes / Fixes |
| 38 | =============== |
| 39 | |

| 41 | forget to tell me what it changes / which problem it fixes / whatever |
| 42 | it is good for ... |

| 44 | |
| 45 | Known Problems |
| 46 | ============== |
| 47 | |
| 48 | * The tuner for the flyvideos isn't detected automatically and the |
| 49 | default might not work for you depending on which version you have. |
| 50 | There is a tuner= insmod option to override the driver's default. |
| 51 | |
| 52 | Card Variations: |
| 53 | ================ |
| 54 | |
| 55 | Cards can use either of these two crystals (xtal): |
| 56 | - 32.11 MHz -> .audio_clock=0x187de7 |
| 57 | - 24.576MHz -> .audio_clock=0x200000 |
| 58 | (xtal * .audio_clock = 51539600) |
