Revision history [back]

Hi there,

I'm trying to write a program that uses 2 cameras. In the first step I open the cameras on by one for configuration (which is left, right, not to use and so on). After that I open the left and right camera each in on thread. I close the configuration with:

destroyWindow(id);

cap.release();

The Problem is after the configuration I get the massage:

  VIDEOIO ERROR: V4L/V4L2: VIDIOC_CROPCAP
    VIDEOIO ERROR: V4L2: Pixel format of incoming image is unsupported by OpenCV
    VIDIOC_REQBUFS: Device or resource busy
    VIDIOC_G_FMT: Bad file descriptor
    Unable to stop the stream.: Device or resource busy
    VIDIOC_G_FMT: Bad file descriptor

Another thing thats happening is that the camera window stays open for much to long. I put a sleep(60) after closing the video feed and the window stays open until the sleep is over. It's like the command is not even executed when the command is given.
