Ok, so now I have tried using the \(fourcc\)NV12, as Ruben suggested and without the single quotes.<div>狢 found more stuff happening on the console. The gr8.264 file got created as well but it seems corrupted. Somehow my camera is not being read is what I feel. Could you please help me with this. Here is the console snapshot<div> </div><div>root@dm365-evm:~# gst-launch -v v4l2src always-copy=FALSE num-buffers=800 input- src=composite ! video/x-raw-yuv, format=\(fourcc\)NV12, width=720, height=480 !
