Hello, This is a bit offtopic, so I will understand if you rather not discuss that... I am trying to use gstreamer with v4l2 vivi device, I first check the capabilities with gst-launch-1.0 --gst-debug=v4l2src:5 v4l2src device="/dev/video0" ! fakesink 2>&1 and it gives many capabilities such as the following: video/x-raw-yuv, format=(string)YUY2, framerate=(fraction)[1/1000, 1000/1], width=(int) 640, height=(int)180, interlaced=(boolean)true So I tried to run as following: gst-launch-0.10 v4l2src device="/dev/video0" ! video/x-raw,width=640,height=180,framerate=30 ! autovideosink But it keeps giving me auto negotiation error -4. Trying to give other values did not help neither. It is probaby more a gstreamer issue, but if someone is familiar and can shed some light on this will will help. Linux version is 3.10.0.
