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.

  • Hmm... It seems like $xx (xx ...) in case of time stamps, where it's not logic to go till the frame end, just means $xx xx xx xx, i. e. 32 bit sized num. – Eldar Feb 13 '23 at 11:40
  • Do you ask for the specific ETCO frame or SYLT? Or what frame type exactly do you mean? – PeterCo Feb 14 '23 at 09:48
  • Your search skills are questionable: see [ID3V2.3, ETCO Frame Event Format Clarification](https://stackoverflow.com/questions/59586097/id3v2-3-etco-frame-event-format-clarification). v2.3 and v2.4 are the same for `ETCO`. – AmigoJack Feb 14 '23 at 10:08
