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

Matroska does not store per stream duration, only global one.

comment:2 Changed 2 months ago by cehoyos

  • Component changed from ffprobe to undetermined

comment:3 Changed 2 months ago by llogan

You can get duration from format instead of stream:

ffprobe -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1 input.mkv
