 Now the output video x264Mask25FPS.mp4 can NOT be played by a number of
 players, namely SMPlayer 0.8, Windows Media Player.
 But it can with VLC 2.05

 If using build ffmpeg-20130209-git-969039e-win64-static (or earlier),
 video x264Mask25FPS.mp4 can be played with all players


 Note changing video codec to mpeg4, does not create the bug.

 Note what about ticket 2289?
