Dear All
Problem:
After connecting 3rd camera, Linux video capture does not work
cam3 or Image capture in cam1 fails.
History:
Initially , we developed a system for surveillance. The system
comprised of 2 cameras.
1. Video capture (Using Motion)
2. Image capture(Using V4L)
We added one more camera to the sytem, which is causing the mess currently.
3. Video capture (Using Motion)
We notice either a video capture or image capture does not work in the
system. various forums, suggested for adding quirk=128 in conf, even
that idd not work out.
