Description (last modified by )
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.

Looks like a regression since abf669479c0098ab5eb184a167e57a70aabb942b.
The esds box reports an object type 0x65, which is for mpeg-2 4:2:2, but the stream is 4:2:0, so it's likely that gpac muxed it wrong.
