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?
