Well mp3 in .mp4 is not really standardized except as MP3on4 which is
not supported, or maybe using object type 0x6B in 'esds' dunno if
quicktime plays them though (patch welcome), ffplay will for sure.

Just use .mov, FFmpeg creates .mov files with mp3 perfectly playbable by
quicktime player, ffplay and even latest flash plugin .115
