|
|
==================
|
|
|
|
Author Gerd Hoffmann
|
|
|
|
|
|
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:
|
|
|
|
.. code-block:: none
|
|
|
|
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.
