Kieran, What was /dev/video2 doing when you tried opening /dev/video3. On DM365 there is a limitation (imposed by hw) that if video2 is using for NV12 image format, you can't open video3. This is because, NV12 requires both planes. But this doesn't prevent you from using video2 & video3 in PIP mode for UYVY format. Please confirm.
