Function Documentation

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

combines 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

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

Fetches 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.
