I'm trying to write a ID3v2.4 parser. But I've got stuck with this part's byte meaning in the ETCO frame:
Time stamp $xx (xx ...)
It couldn't mean some amount of bytes from the first $xx till the end of frame, because it represents timestamps, that can be used more than 1 time. So what is it? Maybe I didn't clearly figure out MPEG frames.
I've tried to google it, but there is no info about it.
