Hi everybody,

I have an OPI+ and gc2035 camera module, i try camera with "motion" according to this tutorial and getting one picture on localhost:8081, after this page display "problem loading page".
however, This is not the main issue. i try to get picture with gstreamer and i see following error:

libv4l2: error setting pixformat: operation not permitted
ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src: Device '/dev/video0' cannot capture at 1600x1200
Call to S_FMT failed for YU12 @ 1600x1200: Operation not permitted.

My gstreamer pipeline is:

gst-launch v4l2src always-copy=false ! 'video/x-raw-yuv, format=(fourcc)I420, width=1600, height=1200' ! ffmpegcolorspace ! ximagesink

I try other resolution but get the same error.

vlc player display correct stream with following command:

cvlc v4l2:///dev/video0

if problem is v4l2 so why vlc display camera stream?

finally sorry for english.

thanks in advance

best regards
