Function Documentation

int ff_rm_parse_packet	(	AVFormatContext *	s,
		AVStream *	st,
		int	len,
		AVPacket *	pkt,
		int *	seq,
		int *	flags,
		int64_t *	ts
	)

Parse one rm-stream packet from the input bytestream.

Parameters:

	s	context containing RMContext and ByteIOContext for stream reading
	st	stream to which the packet to be read belongs
	len	packet length to read from the input
	pkt	packet location to store the parsed packet data
	seq	pointer to an integer containing the sequence number, may be updated
	flags	pointer to an integer containing the packet flags, may be updated
	ts	pointer to timestamp, may be updated

Returns:

0 on success, errno codes on error

int ff_rm_read_mdpr_codecdata	(	AVFormatContext *	s,
		AVStream *	st
	)

Read the MDPR chunk, which contains stream-specific codec initialization parameters.

Parameters:

	s	context containing RMContext and ByteIOContext for stream reading
	st	the stream that the MDPR chunk belongs to and where to store the parameters read from the chunk into

Returns:

0 on success, errno codes on error

void ff_rm_retrieve_cache	(	AVFormatContext *	s,
		AVStream *	st,
		AVPacket *	pkt
	)

Retrieve one cached packet from the rm-context.

The real container can store several packets (as interpreted by the codec) in a single container packet, which means the demuxer holds some back when the first container packet is parsed and returned. The result is that rm->audio_pkt_cnt is a positive number, the amount of cached packets. Using this function, each of those packets can be retrieved sequentially.

Parameters:

	s	context containing RMContext and ByteIOContext for stream reading
	st	stream that this packet belongs to
	pkt	location to store the packet data
