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,
