Hello,

I've cross compiled OpenCv for an IgepV2 (arm cortex A8), and I didn't succeed in openning the video device using a videoCapture object. If I don't specify the size of the frames, it return the following errors:

HIGHGUI ERROR: V4L/V4L2: VIDIOC_CROPCAP

VIDIOC_STREAMON: Invalid argument

If I specify the size of the frames like this:

cap.set(CV_CAP_PROP_FRAME_WIDTH,720);

cap.set(CV_CAP_PROP_FRAME_HEIGHT,576);

it returns "select timeout" two times after few seconds, and crash. I also had "ccdc won't become idle" error.

If I use Gstreamer (without OpenCv), it works and I can see the video. I wonder if there is any other settings in OpenCv (I tried all the cap.set(...) settings, but it says that this property is not available). Also, I didn't cross compile OpenCv with ffmpeg or Gstreamer, but I think only v4l2 matters.

Thanks in advance (and sorry for my english)
