x86_gcc2 uses older ffmpeg than x86_gcc5 so it looks like mjpeg codec has improved in later version. I just tried to play this file on macOS 10.12.4 with the following results:

  • QuickTime 10.4 doesn't play it at all.
  • VLC 2.2.4 plays video just fine and allows to rewind it, however there are lots of audio stuttering (2-3 every second) so it's impossible to understand anything
  • MPlayer OSX Extended plays video too fast and allows to rewind it, audio plays fine.
  • mpv 0.24.0 plays video too fast and allows to rewind it, but the audio keeps looping over and over back to the start.

So it looks like this video is horribly broken and doesn't play well in other major players.

If you know any other player that can play this file please tell :) Otherwise, there is nothing we can do here I'm afraid.

Also, a few hints:

  • there is no need to upload fullscreen shots since screenshot app can crop current window
  • starting MediaPlater from Terminal will provide additional info which might be useful (for other tickets)
  • File info window in MediaPlayer shows codec information which is also useful to know.

You're right, the file looks like it's broken. If nothing useful can be gleaned from it, then close the ticket.

Well, given the results on other platforms, I guess what we do is not so bad now. Let's focus on videos other platforms can play, for now :)

Maybe someone can try good old quicktime 4?

Maybe file a ticket to VLC or Mplayer project? Most likely they could make fixes to ffmpeg which we will benefit from.

Note: See TracTickets for help on using tickets.
