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

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

Parameters

off	byte position within the access unit
remove	Found timestamps will be removed if set to 1, kept if set to 0.
fuzzy	Only use found value if it is more informative than what we already have

int ff_combine_frame	(	ParseContext *	pc,

		int *	buf_size
	)

Combine the (truncated) bitstream to a complete frame.

Returns

-1 if no complete frame could be created, AVERROR(ENOMEM) if there was a memory allocation error
