  1. Application that uses vaapisink renders video frames from a video list. After a few minutes of operation no more video frames are rendered, and threads appear to be waiting indefinitely (always reproducible within 5-15 minutes usually). The "hang" happens always in between video files i.e. when one video stops and the next should begin.
  2.  
  3. Application uses "playbin video-sink=vaapisink" to playback a list of video files. Rendering is done in the application itself with opengl (using vaapisink's "handoff" signal, and binding va surfaces received from vaapisink into application glx/GL textures). Same pipeline is used across files. Instead of using "about-to-finish" signal for "gapless playback", the pipeline is transitioned to PLAYING->READY->PAUSED->PLAYING between each video (and uri set to new file in between). "about-to-finish" is not used because it skips(does not display) several frames from finishing video.

  5. The problem does not happen when using glimagesink (video-sink=glimagesink)
