-Release notes for bttv
-======================
-
-You'll need at least these config options for bttv:
- CONFIG_I2C=m
- CONFIG_I2C_ALGOBIT=m
- CONFIG_VIDEO_DEV=m
-
-The latest bttv version is available from http://bytesex.org/bttv/
-
-
-Make bttv work with your card
------------------------------
-
-Just try "modprobe bttv" and see if that works.
-
-If it doesn't bttv likely could not autodetect your card and needs some
-insmod options. The most important insmod option for bttv is "card=n"
-to select the correct card type. If you get video but no sound you've
-very likely specified the wrong (or no) card type. A list of supported
-cards is in CARDLIST.bttv
-
-If bttv takes very long to load (happens sometimes with the cheap
-cards which have no tuner), try adding this to your modules.conf:
- options i2c-algo-bit bit_test=1
-
-For the WinTV/PVR you need one firmware file from the driver CD:
-hcwamc.rbf. The file is in the pvr45xxx.exe archive (self-extracting
-zip file, unzip can unpack it). Put it into the /etc/pvr directory or
-use the firm_altera=<path> insmod option to point the driver to the
-location of the file.
-
-If your card isn't listed in CARDLIST.bttv or if you have trouble making
-audio work, you should read the Sound-FAQ.
-
-
-Autodetecting cards
--------------------
-
-bttv uses the PCI Subsystem ID to autodetect the card type. lspci lists
-the Subsystem ID in the second line, looks like this:
-
-00:0a.0 Multimedia video controller: Brooktree Corporation Bt878 (rev 02)
- Subsystem: Hauppauge computer works Inc. WinTV/GO
- Flags: bus master, medium devsel, latency 32, IRQ 5
- Memory at e2000000 (32-bit, prefetchable) [size=4K]
-
-only bt878-based cards can have a subsystem ID (which does not mean
-that every card really has one). bt848 cards can't have a Subsystem
-ID and therefore can't be autodetected. There is a list with the ID's
-in bttv-cards.c (in case you are intrested or want to mail patches
-with updates).
-
-
-Still doesn't work?
--------------------
-
-I do NOT have a lab with 30+ different grabber boards and a
-PAL/NTSC/SECAM test signal generator at home, so I often can't
-reproduce your problems. This makes debugging very difficult for me.
-If you have some knowledge and spare time, please try to fix this
-yourself (patches very welcome of course...) You know: The linux
-slogan is "Do it yourself".
-
-There is a mailing list: linux-media@vger.kernel.org
-http://vger.kernel.org/vger-lists.html#linux-media
-
-If you have trouble with some specific TV card, try to ask there
-instead of mailing me directly. The chance that someone with the
-same card listens there is much higher...
-
-For problems with sound: There are a lot of different systems used
-for TV sound all over the world. And there are also different chips
-which decode the audio signal. Reports about sound problems ("stereo
-does'nt work") are pretty useless unless you include some details
-about your hardware and the TV sound scheme used in your country (or
-at least the country you are living in).
-
-
-Finally: If you mail some patches for bttv around the world (to
-linux-kernel/Alan/Linus/...), please Cc: me.
-
-
-Have fun with bttv,
-
- Gerd
