#9892: When ffmpeg converts one mkv file to mp4 it finds errors in it

-------------------------------------+-------------------------------------
This mkv file (https://people.freebsd.org/~yuri/problematic-for-
ffmpeg.mkv) has no errors according to this ffmpeg command:
{{{
$ ffmpeg -v error -i "problematic-for-ffmpeg.mkv" -f null -
}}}
Then the above file is converted to mp4 with this command:
{{{
$ ffmpeg -fflags +genpts -i "problematic-for-ffmpeg.mkv" -codec copy -r 24
"problematic-for-ffmpeg.mkv.mp4"
}}}
to this file: https://people.freebsd.org/~yuri/problematic-for-
ffmpeg.mkv.mp4
Now problematic-for-ffmpeg.mkv.mp4 fails the sane check:
{{{
$ ffmpeg -v error -i "problematic-for-ffmpeg.mkv.mp4" -f null -
