[FFmpeg-user] FFplay question

Hi there,

Not sure if i have the right place for this question but I have several
video files each roughly the same file size and bit rate. They all play
well with vlc/quicktime however with ffplay the audio dropouts every
consistently throughout playback.

This is mediainfo report on one of the files . Is there an incompatible
codec I am working with? I also transcoded the file to a h.264 file with
ffmpeg and it played well in ffplay. I can also make 5 second clip copy and
this plays well.

Any advice? Thanks in advance
