    4 After ''PTS/DTS Invalid clipping'' error, it makes video stream duration a little bit longer and probably audio and video lose synchronisation.. It does not matter if there is sound stream or no sound stream (for out.mp4), the file will not play if we copy h.264 encoded video stream while converting flv to mp4.
