It seems that this timed out happen when OMXCodec's client grab too much MediaBuffer. In stagefright, AwesomePlayer concurrently own at most only one video frame.

following is my related comment in the past.

Thought as much. It looks like it allocates far fewer buffers on my phone than it does on B2G, though. I wonder if that means we can dial it back for B2G.

How does this affect non-media plugin playback on Android? Have you done a try server run to see if it breaks anything there?
