setVideoTrack works with caller but not receiver

[jlubeck]

New Issue Checklist

• [x] I have read the Documentation
• [x] I have searched for a similar issue in the project and found none

I'm using the latest SDK. I can't make the RemoteVideoView work on the receiving end. Whenever I make a video call, the caller gets the video from the receiver. But not the other way around. If I switch roles, same issue again.

Here are my logs on the caller: https://pastebin.com/zx7Qedse Here are my logs on the receiver: https://pastebin.com/zhcCJ6Sn

Here is the code on the viewcontroller:

Hi @jlubeck, move this code:

     // add video capture to session's local media stream
        // from version 2.3 you no longer need to wait for 'initializedLocalMediaStream:' delegate to do it
        self.session.localMediaStream.videoTrack.videoCapture = self.videoCapture;

from view will appear into:

- (IBAction)call:(id)sender{

    if ([Server checkForInternetConnection]){

        if(callButton.tag == 101){

            btnCallingProcess.hidden = NO;
            [btnCallingProcess setBackgroundImage:[UIImage imageNamed:@"V_calling"] forState:UIControlStateNormal];
            callButton.tag = 102;

            // Setup video chat
            NSArray *opponentsIDs = @[opponentID];
            QBRTCSession *newSession = [[QBRTCClient instance] createNewSessionWithOpponents:opponentsIDs
                                                                          withConferenceType:QBRTCConferenceTypeVideo];
///->>>>>>>>>>>  
            newSession.localMediaStream.videoTrack.videoCapture = self.videoCapture;
            [newSession startCall:nil];
///->>>>>>>>>>> and retain new session
            self.session = newSession;
....

Thanks

[ghost]

@jlubeck because you create the session in the call: method, in view will appear session == nil. Plese chek it.

[ghost]

Please check our video sample. We set video capture for local media stream after session creates.

Thanks.

Hi @jlubeck, Any updates?

[jlubeck]

Working on it!

[jlubeck]

It worked!!! But instead of moving from viewWillAppear I had to copy it it. If I just moved it, then it work the other way around and only work on the receiver and not the caller. Thanks!
