TCL CLASS
VideoAgent
The VideoAgent class provides a coarse-grained interface that abstracts away all the details of networked video decoding. This agent is responsible for creating the underlying RTP session for the video channel, for opening and initializing any video decoding hardware, and for creating and deleting software decoder objects to process the compressed bit streams from the network.
Since VideoAgent is derived from the RTPAgent base class, the standard RTP observer API is supported. Any ``interesting'' events (e.g., the arrival of a new RTP flow) within the underlying RTP sessions are relayed to all the observers attached to this agent. (Note that the AudioAgent class catches and handles some of the events on its own.)
Typically, a mash script will create a separate user interface object and attach it to the VideoAgent as an Observer.
