Comment (by Heesuk Jung):

 Hi cehoyos,

 I don't think so because a/v playback of other player such as Avidemux
 works well until end of stream.
 Also avidemux extracts the complete audio pts information of problematic
 files.
 I recommend that you play the probemlatic file using avidemux player.

 Test result of ffmpeg latest mater branch is same as ffmpeg 0.11.1.
