getting sub(channels) with PV-155

[gerritkuehn]

Hi,

I have a PV155 card from Bluecherry here which should be able to do 16 chans. There are 4 video chips on the card and I get /dev/video0 to /dev/video3 from them. The card has 2 connector sets, each with 4 blue and 4 green connectors labeled from 1 to 4.
So I think I should be able to get four channels via each /dev/video device. Using zoneminder 1.24.2 with Linux 2.6.34 all 16 channels are offered when using zoneminders probe menu. I can get the first 4 cameras connected to the first 4 blue connectors as monitors on /dev/videoX, channel 0 without any problem.
However, I cannot get any further camera, so all settings with a channel >0 produce a blue monitor screen only. I've spent two days now searching the net and the forums here, but all hints I found (e.g., setting ZM_CAPTURES_PER_FRAME=4) did not help anything.

Is anyone here who can confirm that this card works with (sub)channels at all? Are there any hints what else I could try to get this working? Any help of course is greatly appreciated.

I think I have the correct combination of ZM_CAPTURES_PER_FRAME and V4L_MULTI_BUFFER now. A major problem was that the 5th channel I wanted to use is obviously broken... I alway get only the blue screen there, no matter what I do. However, I can use three more channels now. So what is working is this:

video0(0)
video0(1)
video1(0)
video1(1)
video2(0)
video2(1) <- broken, for whatever reason
video3(0)
video3(1)


I am still missing two more multiplexed channels per video device. The seem not to be found at all:
psl-video # v4l2-ctl --list-devices

Any input from here why I can see only 2 multiplexed channels per device instead of the expected 4?
