SAA7134 8 Chip 16 Channel

[martynw]

Hello,

I'm trying to get one of these cards to work with Zoneminder:

http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... &rd=1&rd=1

It's an 8 chip SAA7134 card but has 2 channels per card and is therefore 16 channel total.

I've previously got a slightly different card working using the same chips:

http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... &rd=1&rd=1

That one was only 8 channels though and a simple:

Code: Select all

modprobe card=33,33,33,33,33,33,33,33

worked fine with each channel available on /dev/videoX (0) (where X is 0-7)

With the new 16 channel card the same modprobe command seems to work fine but I can't work out how to access each channel in ZM. I seem to get the same "mix" of whatever cameras are connected to the card on every /dev/videoX (Y) (where X is 1-7 and Y is 0-15).

Anybody any ideas on how to set this card up?


Thanks for any pointers!

I have the same card under the name AOP-V8008A. With same problem you describe.
I has tried card number 1 thru 31 and also 33.it runs under a few of this numbers but with same results you describe.
Has you had any success?

I too have tried that card. However, out of the sample I received, all of them had serious video bleed issues. I ended up sending them back to China before figuring it out...

Same problem... So, the conclusion is that saa7134 driver does not support 8 chips on board ? Maybe the V8004 that has 4 chips works... But these boards has so many interference with ghosts... I think these boards are a waste...

With me it found all 8 chips. I just never found the second channel. Nore has anyone else, it seems.

I have a board with eight Saa7130 chips on it. Ubuntu for some reason likes to install the saa7134-alsa driver on that board. I think this is mucking up the works (a little technical jargon there). Been fighting with getting the 7134-alsa driver off and modprobing in a new one. when I dump the alsa driver, xawtv sees the card but it sees all 8 streams at once so its all scrambled up.

I did get this board to work on Kubuntu8.03 and ZM1.22.3. card = 33 did not work, gave me scrambled video. Card=72 did work but I had to list the device path /dev/video0 to 7 depending on the cam and use device channel 2.

Also in /etc/modprobe.d
created a file called saa7134
contents:
options saa7134 card=72,72,72,72,72,72,72,72
blacklist saa7134-alsa

blacklisted the saa7134-alsa driver because it Hardy kept recognizing the capture card as a sound card and loading the alsa driver.

video quality is a bit crummy. troubleshooting crosstalk now. I have not tried the second channel yet but I do see /dev/video10-15 in the /dev folder.
