Dear All

Dunno if it is right forum to ask. I am trying to some solution or run time fix on this 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 system, 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.
