 Summary of the bug:


 Once playback reaches the end of an RTSP stream, I am unable to seek
 anywhere in the video. I have experienced this on many different streams,
 but is easy to see with BigBuckBunny

 Right-click near the end to seek.  Once the video ends, right click
 anywhere to seek and the video will never seek whether playing or paused.
