OStreamBufferedSink Class Reference

#include <OStreamBufferedSink.hh>

Collaboration diagram for OStreamBufferedSink:

Detailed Description

The MediaSink, from which this class derives, will receive RTP packets from the net. Then decapsulate them and pass to a "sinker" class. In this case it's this class. OStreamBufferedSink will pass the received packets, via callbacks, to other processing classes.
