Description

An interface that allows the connection manager to control the video stream.

This interface is generally not needed. In cases where the connection manager handles the network communication and the media is transferred from the client to the connection manager via shared memory, it can sometimes be beneficial for the connection manager to be able to control certain aspects of the video stream.
