V4L/DVB (7366): Support for a 16-channel bt878 card
I have what looks like a Geovision GV-600 (or 650) card. It has a large
chip in the middle labeled
CONEXANT
FUSION 878A
25878-13
E345881.1
0312 TAIWAN
It has an audio connector coming out from a chip labeled
ATMEL
0242
AT89C2051-24PI
It is identified as follows on my Debian GNU/Linux Etch (kernel 2.6.18)
...
01:0a.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11)

It was being detected as a GENERIC UNKNOWN CARD both by the 2.6.18
kernel and the latest v4l-dvb drivers, but it did not work at all. The
card has sixteen (16) BNC video inputs, four of them on the board itself
and twelve on three daughter-cards. It has a single bt878 chip, no tuner
and what looks like and audio input. After doing some research I managed
to get only eight channels working by forcing card=125 and those DID NOT
match channels 0-7 on the card, and no audio.
Based on what was working for card=125, I added the card definition
block, added a specific muxsel routine and got the card working fully
with xawtv, where the sixteen channels show up as Composite0 to
Composite15, matching the channel labels in the card and daughter-cards.
I have made no efforts yet to get audio working, but would appreciate
any pointers.

V4L/DVB (10827): Add support for GeoVision GV-800(S)
I have a GeoVision GV-800(S) card, it has 4 CONEXANT BT878A chips.
It has 16 video inputs and 4 audio inputs, and it is almost identical
to the GV-800, as seen on http://bttv-gallery.de .
The only difference appears to be the analog mux, it has a CD22M3494
in place of the MT8816AP. The card has a blue PCB, as seen in this
picture: http://www.gsbr.com.br/imagem/kits/GeoVision%20GV%20800.jpg .
This card wasn't originally supported, and it was detected as
UNKNOWN/GENERIC. The video inputs weren't working, so I tried
"forcing" a few cards like the GeoVision GV-600, but there was still
no video. So I made a patch to support this card, based on the Kodicom
4400r.
The GV-800(S) is identified as follows:

As you can see, the GV-800(S) card is almost identical to the GV-800
on bttv-gallery, so this patch might also work for that card. If not,
only a few changes should be required on the gv800s_write() function.
After this patch, the video inputs work correctly on linux 2.6.24 and
2.6.27 using the software 'motion'. The input order may seem a little
odd, but it's the order the original software/driver uses, and I decided
to keep that order to get the most out of the card.
I tried to get the audio working with the snd-bt87x module, but I only
get noise from every audio input, even after selecting a different mux
with alsamixer. Also, after trying to play sound from those sources, I
randomly get a RISC error about an invalid RISC opcode, and then that
output stops working. I also can't change the sampling rate when
recording. Any pointers to adding audio support are welcome.
