Comment (by ahthovaikied):

 Replying to [comment:19 Cigaes]:
 > I would suggest to test with {{{ffprobe -show_data}}} (or
 {{{-show_data_hash}}}): that would allow to find out whether the
 difference is in demuxing or in the treatments that the command-line tool
 {{{ffmpeg}}} applies to the content.

 Without {{{--disable-vaapi --disable-vdpau}}}:
