Multiple viewer unable to connect simultaneously

[deepaksaxenakent]

When a single master publishing Audio-video stream and 1 viewer is subscribing that stream and another viewer wants to subscribe then the whole system hangs and the publisher stops working

Scenario Steps:

1. Master starts publishing the stream on channel ‘A’
2. Viewer V1 connects and subscribe Channel A’ and can see and publish Audio-video
3. Viewer V2 connects and want to subscribe to the Channel ‘A’

Expected Result: Both viewer and the master simultaneously Result Observed: When V2 connects then all Master viewers stuck

Please refer to the sample in this branch : https://github.com/awslabs/amazon-kinesis-video-streams-webrtc-sdk-ios/tree/multiple-viewer-sample

Hope this helps!

Thanks, Divya

Hi Deepak,

Can you verify if the region in the sample is correct? The crash logs are pointing to 'a invalid region type'. Can you please confirm?

Thanks, Divya

1. On physical device iOS 12.4.8 
Line number 169 in WebRTCClient its crashing I.e remoteVideoTrack?.add(self.remoteRenderer!) because of finding self.remoteRenderer to nil.
2. Unable to run the project on simulator (compile-time error)

// Primary can show only one remoteVideoTrack of Viewer1 on the UI. // All the other remote tracks from viewers are ignored and not added to the remoteRenderer. if (self.peerConnectionMap.count < 2) { remoteVideoTrack = peerConnection.transceivers.first { $0.mediaType == .video }?.receiver.track as? RTCVideoTrack remoteVideoTrack?.add(self.remoteRenderer!) // Crashes here }

@dswamina do you have any further update on this issue?

@deepaksaxenakent has your original issue been resolved?

I would like to get more traction on this issue and not let it go stale
