Hi,

Any fix yet for your issue? I am having similar problem. I can get my camera to work on one channel, I am using Fedora core 7, I had this working with Fedora core 6, so I am thinking it is a software or configuration problem on my part.

I can get the cameras both to work on one channel independently, when I use two inputs I cannot get both cameras to work, I can get one to work but get a blank screen on the other channel. Sometimes I can get two pictures of the same camera to show with different sources! Weird huh?

Fedora uses /dev/video0, /dev/video1, /dev/video2 and /dev/video3. The BT878 is from BlueCherry and has seperate BT878 chips for each input, so it is "capable" of 120fps, but I am keeping the FPS low, like 5 fps.

Let me know if you get any solution to your problem.

Thanks,

John

Channel or chips? /dev/video0 is the first chip, and /dev/vedio1 is the second and so on... Channels are if you have split chips, like the PV-155-16 from Blue Cherry.
