Comment (by ponpon):

 using a patch
 http://permalink.gmane.org/gmane.comp.video.ffmpeg.devel/214982, 480p.mp4,
 720p.mp4, 1080p.mp4 can be playbacked with videotoolbox on osx1095.
 test.mp4 may not be supported by videdotoolbox because it can be
 playbacked with commands on #5272.

 playbacking 480p.mp4, 720p.mp4, 1080p.mp4 with -hwaccel auto  and the
 it seems hwaccel auto uses vda and falls back h264 decoder of ffmpeg.
 where videotoolbox hardware decoding isnt used.
 i dont know if it is a right behavior.
