fmp4/mp4: initial implementation of flac in mp4
Still a very initial implementation of storing flac in mp4 and fmp4. Based on information in isoflac.txt and my own experience playing these files to a phone and such.
Remaining things:
-
Tests? -
In-line TODOs/comments -
Extend this to regular mp4mux?
Creating this initial draft PR to gather feedback on approach and to have something concrete in hand when asking questions.
