- Scan every frame header of the file.... This does not require a

Do you have any sample code to do this? I need to do it for a completely different reason (multiplexing Layer II data into a MPEG-2 transport stream)

Look at scan() (and calc_length()) in this file. It tries to calculate the length of an mp3 regardless of whether it's VBR or not, and whether it has XING tags or not.
