Is there any support for VBR headers in MAD?
I'm trying to calculate the length of files and for CBR fileSize/(header.bitrate/8) works fine. For VBR, this obviously gives an incorrect answer.
If reading VBR headers is fiddly, I was also thinking of checking the bitrate in say 10 or so frames at the start, take their average bit rate and use that in the calculation above. Would that be even remotely accurate for VBR?
Thanks, Erik
