#6969: H.264 MP4 playback issues relative to Apple Compressor

Summary of the bug: FFmpeg H.264 MP4 movies don't play as well as similar
movies encoded with Apple Compressor.
How to reproduce: Create an H.264 MP4 from FFmpeg, and another using Apple
Compressor. Then play the movies in QuickTime player or VLC. The Apple
version generally maintains frame rate much better than the FFmpeg
version.
Or just try playing the two MP4s I'm attaching.
