Bug 734608 didn't completely fix the last missing frames. I have been able to
try this in a 32-core machine with and we never rendered the last 20 frames
(from a total of 300).

The problem is in the do-while loop in gst_ffmpegviddec_drain. It only retries
10 times, but this might not be enough. I guess this machine has more frames
decoded but only 10 are decoded on draining.
