INmChannelVideoNotify
INmChannelVideoNotify is the event sink for INmChannelVideo. The NetMeeting 3 run time calls INmChannelVideoNotify methods when certain events are triggered specifically concerning video channels.
When to Implement
Implement INmChannelVideoNotify in NetMeeting client applications to process event notifications from the NetMeeting run time. For example, the INmChannelVideoNotify::StateChanged method is notified when the state of the video channel changes.
When to Use
You do not normally call INmChannelVideoNotify methods directly. The NetMeeting run time calls these methods when certain events are triggered by calls to INmChannelVideo methods.
