Comment (by cehoyos):

 Can you confirm that your actual issue is not that FFmpeg does not write
 files compatible with {{{mp42}}}? You could use a binary efitor to test if
 the minor version really makes any difference.
 If you can point me to the player in question, I would be able to test
 myself.
