Try with -vfm ffmpeg. Though it should not crash, hardframedrop seriously breaks
the stream as it does not even decode the frames - and the libmpeg2 decoder is
optimized for speed and has little error resilience.
So you should better use only framedrop or you can also use -vfm ffmpeg together
with lowres decoding.

  • Resolution set to wontfix
  • Status changed from new to closed

Currently looks like a libmpeg2 crash due to hardframedrop. Unless exploitable
(does not look like it) this won't be fixed.
If you have differing/additional information, reopen.
