            Bug ID: 777354
           Summary: v4l2 Doesn't Stop After Device Removed
    Classification: Platform
           Product: GStreamer
           Version: unspecified
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-good
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: casey.zahorik at qsc.com
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

Versions: 1.10.2 and 10.8.3 (probably versions after as well)

Pipeline: gst-launch-1.0 v4l2src device=/dev/video0 ! fakesink 

Problem: When the usb device providing the video for /dev/video0 is unplugged,
gstreamer doesn't crash or detect the device has been unplugged and stop. This
causes the device, when plugged back in, to re-enumerate as another device
instead of having the same path as before. 

This is not a problem when using older versions of gstreamer/v4l2. I have tried
it on 1.2 and 1.4, both work as expected.
