Detailed Description

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,
