[Elphel-support] issues with OpenCV

Hello,

I try to open a stream to the camera in OpenCV (Windows OS). OpenCV throws these error messages:
>>>>>>>>>>>
[rtsp @ 0xbefd80]Estimating duration from bitrate, this may be inaccurate 
picture size invalid (0x0)
Last message repeated 1 times
[rtsp @ 0xbf2480]Estimating duration from bitrate, this may be inaccurate
<<<<<<<<<<<
So I have experienced the same issues with the FFMPEG like in this example <http://wiki.elphel.com/index.php?title=Talk:OpenCV>
Unfortunately it was not possible for us to rebuild the Windows version of OpenCV with GStreamer instead of FFMPEG.
Could you give us some advice for establishing the stream?

Thanks,
Sebastian
