  1. gstreamer 1.8.0 Trying to play through list of videos without using about-to-finish signal. The video list loops to beginning endlessly.
  2.  
  3. The following testcase successfully switches through 2-12 videos but then output goes blank/ no more video is displayed (reproducible about 50% of the time, in other runs video switching is successful for more than 30 videos). Backtrace of all threads during blank output/stopped switching follows source code.
  4.  
  5.  
  6. usage: test.c videofile1 videofile2 ...
  7.  
  8. Playbin video sink is set manually to a user-provided vaapisink (same problem also happens with a glimagesink)
