I'm trying to set the proper MIME-type for an AAC file, but this command does not work:
ffmpeg -i rain.mp3 -metadata mime-type="audio/aac" rainmp3toaac.aac
but, actualy audio/x-hx-aac-adts
is set.
So, how I can force another MIME-type?
I found solution after few day of researching. It's very simple:
ffmpeg -i rain.mp3 -f mp4 rainmp3toaac.aac
and now mime-type is audio/mp4
and that is fine for me.
