[FFmpeg-user] Fmp4 overhead vs ADTS/AAC

[Ronak Patel]

Hi all,

I was curious about the best way to calculate the overhead of an fmp4 file vs ADTS. The fmp4 will just contain audio.

I tried calculating the size of the ftyp, moov and subsequent moof and sidx boxes but that seems like it’s not enough.

Is a portion of mdat overhead as well? If so, what would be the best way to calculate this?

Thanks
