5 You'll need at least these config options for bttv:
10 The latest bttv version is available from http://bytesex.org/bttv/
13 Make bttv work with your card
14 -----------------------------
16 Just try "modprobe bttv" and see if that works.
18 If it doesn't bttv likely could not autodetect your card and needs some
19 insmod options. The most important insmod option for bttv is "card=n"
20 to select the correct card type. If you get video but no sound you've
21 very likely specified the wrong (or no) card type. A list of supported
22 cards is in CARDLIST.bttv
24 If bttv takes very long to load (happens sometimes with the cheap
25 cards which have no tuner), try adding this to your modules.conf:
26 options i2c-algo-bit bit_test=1
28 For the WinTV/PVR you need one firmware file from the driver CD:
29 hcwamc.rbf. The file is in the pvr45xxx.exe archive (self-extracting
30 zip file, unzip can unpack it). Put it into the /etc/pvr directory or
31 use the firm_altera=<path> insmod option to point the driver to the
34 If your card isn't listed in CARDLIST.bttv or if you have trouble making
35 audio work, you should read the Sound-FAQ.
41 bttv uses the PCI Subsystem ID to autodetect the card type. lspci lists
42 the Subsystem ID in the second line, looks like this:
44 00:0a.0 Multimedia video controller: Brooktree Corporation Bt878 (rev 02)
45 Subsystem: Hauppauge computer works Inc. WinTV/GO
46 Flags: bus master, medium devsel, latency 32, IRQ 5
47 Memory at e2000000 (32-bit, prefetchable) [size=4K]
49 only bt878-based cards can have a subsystem ID (which does not mean
50 that every card really has one). bt848 cards can't have a Subsystem
51 ID and therefore can't be autodetected. There is a list with the ID's
52 in bttv-cards.c (in case you are intrested or want to mail patches
59 I do NOT have a lab with 30+ different grabber boards and a
60 PAL/NTSC/SECAM test signal generator at home, so I often can't
61 reproduce your problems. This makes debugging very difficult for me.
62 If you have some knowledge and spare time, please try to fix this
63 yourself (patches very welcome of course...) You know: The linux
64 slogan is "Do it yourself".
66 There is a mailing list: linux-media@vger.kernel.org
67 http://vger.kernel.org/vger-lists.html#linux-media
69 If you have trouble with some specific TV card, try to ask there
70 instead of mailing me directly. The chance that someone with the
71 same card listens there is much higher...
73 For problems with sound: There are a lot of different systems used
74 for TV sound all over the world. And there are also different chips
75 which decode the audio signal. Reports about sound problems ("stereo
76 does'nt work") are pretty useless unless you include some details
77 about your hardware and the TV sound scheme used in your country (or
78 at least the country you are living in).
81 Finally: If you mail some patches for bttv around the world (to
82 linux-kernel/Alan/Linus/...), please Cc: me.
