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: video4linux-list@redhat.com.
|
||
|
|
https://listman.redhat.com/mailman/listinfo/video4linux-list
|
||
|
|
|
||
|
|
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 alot 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,
|
||
|
|
