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.

Ok, I've done a couple more tests. With larger frames, and, therefore 
lower fps - yes, with your patch buffers toggle correctly. Whereas in my 
tests with smaller frames and higher fps either only one buffer is used, 
or one is used much more often, than the other, e.g., 0 0 0 1 0 0 0 1 0... 
Could you try to verify? Without your patch with any fps buffers toggle 
consistently.

How small are the frames in you test? What is the highest fps value in
your test?

QVGA, don't know fps exactly, pretty high, between 20 and 60fps, I think. 
Just try different frams sizes, go down to 64x48 or something.

Thanks
