Conference multi party video conversation not working (conference.js has issue)

[satishakumar]

I am working for Skype for business online using Skype web sdk. I am trying to create multi party video conversation i.e video conference.

I am using below code to create conversation.

var conversation = app.conversationsManager.createConversation(); //created conversion
//self video listener
conversation.selfParticipant.video.state.changed(function (newState, reason, oldState) {
    notify("selfParticipant.video.state : "+newState)
});
//self audio listener
conversation.selfParticipant.audio.state.changed(function (newState, reason, oldState) {
    notify("selfParticipant.audio.state :"+newState);
});
//listner for conversion state
conversation.state.changed(function (newValue, reason, oldValue) {
    notify("conversation.state : "+newValue)
});

//add participants
addParticipants(conversation,sip_uris); //Added participants

notify("conversation.videoService.maxVideos : "+conversation.videoService.maxVideos());
notify("conversation.videoService.videoMode : "+conversation.videoService.videoMode());
//start video service
conversation.videoService.start().then(function () {
    notify("Video conference successfully started : "+conversation.uri());
},function (error) {
    notify("Video conference start failed : "+error);
});

And logs of above code as bellow

1:26:51 PM : selfParticipant.video.state : Disconnected
1:26:51 PM : selfParticipant.audio.state :Disconnected
1:26:51 PM : conversation.state : Created
1:26:51 PM : conversation.videoService.maxVideos : null
1:26:51 PM : conversation.videoService.videoMode : ActiveSpeaker
1:26:52 PM : conversation.state : Conferenced
1:26:53 PM : selfParticipant.audio.state :Connecting
1:26:53 PM : selfParticipant.video.state : Connecting
1:27:04 PM : selfParticipant.audio.state :Connected
1:27:04 PM : selfParticipant.video.state : Disconnected
1:27:04 PM : Video conference successfully started

I am having two issues.

• conversation.videoService.maxVideos showing as null (my browser details - chrome Version 56.0.2924.87 (64-bit)).

• selfParticipant.video.state getting Disconnected, but selfParticipant.audio.state is fine(changing to connected).

Same question I have asked stackoverflow, no solution.

Skype web SDK logs

Any help appreciated.
