[413278730]

When the second person joins the room, the first person crash.
What causes this? How do I solve this problem?
And VideoView shows some debug messages, how to remove it?

I think the Metal renderer doesn't like what you are publishing.

May I know:

• What are you publishing from ?
• Dimensions of the video you are publishing ?
• If VideoView with renderMode = .sampleBuffer works ?

I didn't set any video related parameters, everything is default.

After I set renderMode =.sampleBuffer, it did not crash, but the size of the video was compressed (originally rectangular, now it is square), what is going on?

What does changing renderMode =.sampleBuffer change?

lazy var room = Room(delegate: self)

        try await room.connect(url: url, token: token)
        try await room.localParticipant.setCamera(enabled: true)
        try await room.localParticipant.setMicrophone(enabled: true)

func room(_ room: Room, participant: RemoteParticipant, didSubscribeTrack publication: RemoteTrackPublication) {
DispatchQueue.main.async {
if let track = publication.track as? VideoTrack {
self.remoteVideoTrackSubject.send(track)
}
}
}

func update(track: VideoTrack?) {
self.videoView.track = track
}

Is Metal debugging off in your Xcode scheme settings?

1.What is the difference between .metal and .sampleBuffer in RenderMode?

When I set videoView.renderMode = .auto， the video layer is full screen.

But when I set videoView.renderMode = .sampleBuffer is half-screen. how do I make it full screen as well?

I just set renderMode, no other properties.
private lazy var videoView: VideoView = {
let videoView = VideoView()
videoView.add(delegate: self)
videoView.renderMode = .sampleBuffer
return videoView
}()
