Detailed Description

This file contains the functions that perform playout buffer and make possible to access packets pending on the buffer.

Function Documentation

rtp_pkt* rtp_get_n_pkt	(	rtp_ssrc *	stm_src,
		unsigned int *	len,
		unsigned int	pkt_num
	)

Returns a pointer to Nth packet in the bufferpool for given playout buffer. WARNING: the pointer returned is the memory space of the slot inside buffer pool: Once the packet is decoded it must be removed from rtp queue using

See also:

rtp_rm_pkt. WARNING: returned pointer looks at a memory space not locked by mutex. This because we suppose that there is only one reader for each playout buffer. We lock mutex only for potail var reading.

Parameters:

	stm_src	The source for which to get the packet
	len	this is a return parameter for lenght of pkt. NULL value is allowed: in this case, we understand that you are not interested about this value.
	pkt_num	The index of the packet we want to get. shawill: this function put his dirty hands on bufferpool internals!!!

Returns:

the pointer to next packet in buffer or NULL if playout buffer is empty.

static void socket_clear

(

rtp_ssrc *
