            Bug ID: 755049
           Summary: intervideosrc doesn't render the preroll frame (in
                    paused state)
    Classification: Platform
           Product: GStreamer
           Version: git master
                OS: All
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: ben.browitt at gmail.com
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

When seeking on playbin connected to inter elements in paused state, the
prerolled frame is not rendered.
The timeout property of intervideosrc has no effect.

To reproduce load the test video and the python scripts to the same folder.
Both scripts do the following:
- Change state to PLAYING.
- After 10 seconds, change state to PAUSED.
- After 15 seconds, seek playbin.
- After 20 seconds, change state to PLAYING.
- After 30 seconds, stop the program.

The playbin.py script doesn't use inter elements. The image is updated when
seeking in PAUSED state.
The playbin2.py script uses inter elements. The image isn't updated when
seeking in PAUSED state.
