[Mp4-tech] another audio codec inside MP4 File

[Ravi]

Hi Experts,
I want to know if another audio stream instead of Mpeg-4 AAC
can be embedded inside the MP4 File Format.
i.e if ac3 or mp3 audio can be added with MP-4 Elementary Stream (video)
inside the MP4 File.
Or same can be done with ISO Based Media file format.
