Hi Simen, Sorry I think this issue has been reported as:
https://opencast.jira.com/browse/MH-5404 Can you see the video properly if you launch the following command: gst-launch v4l2src device=/dev/video0 ! queue ! videorate ! video/x-raw-rgb ! ffmpegcolorspace ! ffenc_mpeg2video ! mpegtsmux ! filesink location=/tmp/test.mpg The issue was that the card was dumping rgb (so you have to set the caps) vs yuv so your "video/x-raw-yuv" will become " video/x-raw-rgb".
