MeetingMediaEvent

MeetingMediaEvent carries media events of the current meeting and is registered through MeetingEngine.mediaEvent. You can extend MeetingMediaSimpleEvent and override only what you need.

Usage notes

This interface covers connection state, raw remote frames, and aggregated quality statistics; for the receive state of a single remote video, use MeetingRemoteVideoEvent.
onRemoteVideoFrame() is called back on the SRTC media thread and must not block.
Media statistics are usually produced about every 5 seconds; for poor-network level changes, prefer onNetworkQualityChanged().
This listener is cleared when you exit the meeting; reassign it for the next meeting.
