Stream events

[Marçal_S_]

Hello. 

I'm using MCU v3.4 and Javascript SDK sample code, when i enable or disable Audio/Video streams the other peers doesn't receive the events.

The code I use to handle events :

['VideoEnabled', 'AudioEnabled', 'VideoDisabled', 'AudioDisabled'].map(
        function(event_name) {
              stream.on(event_name, function() {
                   L.Logger.info('stream', stream.id(), event_name);
              });
        });

And the other peer action was:

stream.disableAudio();

Anyone can help me? is there something wrong? Thanks!

RemoteMixedStream.emit('VideoEnabled', evnet); 

RemoteMixedStream.on('VideoEnabled', function(event) ;

This can, but only inform this client

Are you right. If you emit an event in RemoteStream of an user, you receive the event in RemoteStream of this stream, but its locally and don't make sense.

In the documentation says that this kind of events was reserved by MCU and triggers when the streams change.

void Woogeen.RemoteStream.on( string event, function listener )

This function registers a listener for a specified event, which would be called when the event occurred.

Remarks:

Reserved events from MCU:

Event Name	Description	Status
VideoLayoutChanged	Video layout of the mix (remote) stream changed	stable
VideoEnabled	Video track of the remote stream enabled	stable
VideoDisabled	Video track of the remote stream disabled	stable
AudioEnabled	Audio track of the remote stream enabled	stable
AudioDisabled	Audio track of the remote stream disabled	stable

User-defined events and listeners are also supported, See stream.emit(event, data) method.

Reading this, I understand, when user disable audio in his LocalStream, the others users in the room must receive in their remoteStreams of that user an AudioDisabled event. It must works like this behavior? or i'm wrong

Currently found only VideoLayoutChanged can receive the notice from the MCU, audio and video status can not be received, unless this bug. Now only through the send way to broadcast messages to achieve

me be you can try 'StateChange', from to SDK 'update_stream'

Hi Marçal,

disableAudio/disableVideo only disables audio/video tracks on you local machine. It does not send message to remote side.

Then I don't understand when the events fires, i tried tons of modifications but Enable/Disable Video/Audio events never triggers.

Other thing  I can't understand it's: when you emit an event through an RemoteStream only the user that fires the event receive this event :S

Has been modified by modifying the updateStream audio and video status changes

session_agent/session.js

n.updateStream = function(e, o, r, n) {

log.info("updateStream:", e, r,o), 

g("room", "all", "update_stream", {

event: "StateChange",

id: e,

state: r,

type:o

}), i ? (i.updateStream(e, o, r), n("callback", "ok")) : n("callback", "error", "Controller is not ready")

}

woogeen.sdk.js

j.socket.on("update_stream", function(a) {

//if(void 0 !== j.remoteStreams[a.id]) return void e.Logger.warning("stream already added:", a.id);

var b = j.remoteStreams[a.id];

if(a.event == 'StateChange') {

c = new d.StreamEvent({

type: "stream-update",

stream: b,

msg:a.state,

avType:a.type

});

j.dispatchEvent(c);

} else {

b && b.emit(a.event, a.data)

}

})

conference.on('stream-update', function(event)
