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)
