Re: [Linux-uvc-devel] Trouble recording from two webcams

Hey Vidar, I just did a little testing with two cameras, a QuickCam for Notebooks Pro (2006 model) and a QuickCam Orbit MP/Sphere MP (2006 model). Using two instances of luvcview the following combinations work (only tested at the default resolutions): MJPEG: All combinations up to 2 x 640x4
