I can't try mplayer since I don't have mplayer setup for this.
But looking at the mplayer source I don't see why it should
behave differently. Depending on mode mplayer queues 2 or 6
buffers. Testing with my test app with 6 queued buffers shows
no issues, here the buffer numbers toggle correctly, too.
