libv4l2 error setting pixformat - gc2035 OPI+

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 errors:

 

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?

 

#uname -a

 

Linux orangepiplus 3.4.112-sun8i #14 SMP PREEMPT Tue Jul 5 16:28:14 CEST 2016 armv7l GNU/Linux

 

thanks in advance

 

best regards
