void ff_fetch_timestamp ( AVCodecParserContext s,
int  off,
int  remove,
int  fuzzy 
)

Fetch timestamps for a specific byte within the current access unit.

Parameters
offbyte position within the access unit
removeFound timestamps will be removed if set to 1, kept if set to 0.
fuzzyOnly use found value if it is more informative than what we already have
