Receiving mixer incoming stream event
Since build 5.2.966, a subscriber playing mixer output stream, can receive incoming mixer sterams events. In this case, streamName
field is added to payload
objects to show what stream publisher generated the event

session.createStream({
name: streamName,
display: remoteVideo,
...
}).on(STREAM_EVENT, function(streamEvent) {
let mutedName="";
if(streamEvent.payload !== undefined) {
mutedName=streamEvent.payload.streamName;
}
switch (streamEvent.type) {
case STREAM_EVENT_TYPE.AUDIO_MUTED:
$("#audioMuted").text(true + " " + mutedName);
break;
case STREAM_EVENT_TYPE.AUDIO_UNMUTED:
$("#audioMuted").text(false + " " + mutedName);
break;
case STREAM_EVENT_TYPE.VIDEO_MUTED:
$("#videoMuted").text(true + " " + mutedName);

Stream status detection while subscriber is connecting to a stream
A new subscriber can detect if audio/video track is muted in the stream while connecting to the stream using Stream.getAudioState() and Stream.getVideoState() methiods in STREAM_STATUS.PLAYING handler:

session.createStream({
name: streamName,
display: remoteVideo,
...
}).on(STREAM_STATUS.PLAYING, function (stream) {
if (stream.getAudioState()) {
$("#audioMuted").text(stream.getAudioState().muted);
}
if (stream.getVideoState()) {
$("#videoMuted").text(stream.getVideoState().muted);
}
...
}).play; |
Mixer incoming streams status detection while connecting to a mixer outgoing stream
Since WCS build 5.2.1011, when a new subscriber connects to a mixer outgoing stream, it will receive a set of STREAM_EVENT events per every mixer incoming stream, if audio or video track was muted at least once in any of them. In this case, STREAM_EVENT receiving order is not guaranteed and does not depend on streams addition order to the mixer.
