 '''Summary of the bug:'''
 This ticket is coming from original post written here:
 https://github.com/HandBrake/HandBrake/issues/1609

 It seems Handbrake encoding app is using ffmpeg as a muxer for mkv files
 (?)
 Some statistics (like video & audio bit rate) will be missing from the
 metadata of the resulted mkv file.

 Other encoding apps that are using libmatroska to mux have those
 statistics (see printscreen in my original post).

 Here is the source code of the matroska lib that generate track stats:

 https://gitlab.com/mbunkus/mkvtoolnix/blob/master/src/common/track_statistics.h
