-------------------------------------+----------------------------------
Recent versions of ffmpeg do not recognize MP4 files with MPEG-2 video
created by MP4Box, only the ones created by ffmpeg itself. However old
versions of ffmpeg such as 3.4.2 didn't have this problem.

And as a consequence, software that uses ffmpeg demuxers such as mpv and
LAV Splitter are failing as well.
Here is the link to two sample files, one created with GPAC's MP4Box and
the other created with ffmpeg 4.1.4.
