Same video on multiple /dev/video monitors

[the_crowbar]

The short question: When setting up monitors my video feed is shown for each of the /dev/video0(0,1,2,3) devices. The same video appears as if the camera output is split and sent to each input.

Details:
I have a Ubuntu server 8.04 LTS system that has self compiled ffmpeg 0.5 and ZM 1.24.1. It is AMD64 if it matters. I have a ProVideo PV155 16 port card and a EureSys 16 port card. Here is part of the dmesg log from the first two /dev/video devices:

I have ZM working. I can setup several monitors and view the video feeds. The problem comes in when I try setting up monitors for each input of each /dev/video device. I setup /dev/video0(0) then /dev/video0(1) and /dev/video0(3). I then try to view the monitors and each one appears to have the same video feed on it.

I have tried removing all monitors and recreating them. I got the first two inputs setup and they showed the correct video. When I added the /dev/video0(2) monitor then all three showed the same video.

Any ideas?

Thanks,

go to: Option\Config find CAPTURES_PER_FRAME

increase CAPTURES_PER_FRAME to 2 instead of 1

Thanks! That seems to fix that problem.
