           Summary: [v4l2src] Hangs capturing frame
    Classification: Desktop
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
        AssignedTo: gstreamer-bugs at lists.sourceforge.net

gstreamer-plugins-good-0.10.17-4.fc12.x86_64
gstreamer-0.10.25.1-3.fc12.x86_64
gstreamer-plugins-base-0.10.25.1-2.fc12.x86_64

When using the "cheese-test-chooser" test program from cheese master, the
capture sometimes hangs, leaving the webcam in use, and the program frozen.

Using libv4l2's debug facility (LIBV4L2_LOG_FILENAME=/tmp/log as envvar), I get
loops of:
request == VIDIOC_DQBUF
result == 0
request == VIDIOC_QBUF
result == 0
