Synchronization Source internal handler within the incoming packets queue.
Incoming packets queue objects hold a hash table and a linked list of synchronization sources. For each of these sources, there is also a linked list of incoming rtp packets, which are linked in an 'all incoming packets' list as well. SyncSourceLink objects hold the necessary data to maintain these data estructures, as well as source specific information and statistics for RTCP,
Author:
Note it deletes the source.
Compute cumulative packet lost and fraction of packets lost during the last reporting interval.
Get first RTP (data) packet in the queue of packets received from this socket.
Mark this source as having sent a BYE control packet.
Returns:
Mark this source as having sent some packet.
Returns:
Get last RTP (data) packet in the queue of packets received from this socket.
Get the highest valid sequence number received.
Get the link object for the next RTP source.
Get the link object for the next RTP source in the hash table entry collision list. Note that collision does not refer to SSRC collision, but hash table collision.
Get the total number of payload octets received from this source.
Get the total number of RTP packets received from this source.
Get the link object for the previous RTP source.
Get the synchronization source object this link objet holds information for.
Start a new sequence of received packets.
Record the insertion of an RTP packet from this source into the scheduled reception queue. All received packets should be registered with recordReception(), but only those actually inserted into the queue should be registered via this method.
Parameters:
Set the highest valid sequence number recived.
Parameters:
Get conflicting address.
