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

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.

int ff_combine_frame	(	ParseContext *	pc,
		int	next,
		const uint8_t **	buf,
		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
