Does "within 16 bytes" mean before or after the syncpoint startcode? This description also doesn't mention that this value is relative.
[...] and within 16 bytes is supposed to mean that the startcode begins on the pointed-to byte or one of the 15 following bytes. i suppose this could use some clarification in the spec. :)
Okay. Changes made: - replaced "within 16 bytes of" with "up to 15 bytes before" - mentioned that it's relative - replaced "original syncpoint" with "current syncpoint" (both terms were used for the same syncpoint)
