WebRTC Swift RemoteStream 未呈现

Question

我已经通过 Outlet 创建了 RTCMTLVideoView。

@IBOutlet weak var otherEndVideoHolderView : RTCMTLVideoView!

并从 RTCPeerConnectionDelegate 委托中收集 RTCMediaStream

    func peerConnection(_ peerConnection: RTCPeerConnection, didAdd stream: RTCMediaStream) {
    debugPrint("peerConnection did add stream")

    if let video = stream.videoTracks.first{
        self.remoteVideoTrack = video
        self.delegate?.webRTCClient(self, didReceiveRemoteRender: video)
    }
}

Offer 之后 -> Answer -> 并且对等状态为 connected。仅渲染本地视频。远程视频未呈现。

Answer 1

我最近从事 Webrtc 工作，并在 collectionview 单元格上添加了远程流。你可以使用我的代码。如果您有任何其他问题，请告诉我，我也会提供帮助。

let stream = VideoCallViewController.arrRemoteStreams[indexPath.row]


    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "RmoteVideoCollectionViewCell", for: indexPath) as! RmoteVideoCollectionViewCell

    cell.contentView.subviews.forEach({ [=10=].removeFromSuperview() })

    #if arch(arm64)
    // Using metal (arm64 only)
    let remoteRenderer = RTCMTLVideoView(frame:  CGRect.init(x: 0, y: 0, width: 150, height: 150))
    remoteRenderer.videoContentMode = .scaleAspectFit

    #else
    // Using OpenGLES for the rest
    let remoteRenderer = RTCEAGLVideoView(frame:  CGRect.init(x: 0, y: 0, width: 150, height: 150))
    #endif



     //set stream to cell
    stream.videoTracks.first?.add(remoteRenderer)

    //adding stream to cellview
    cell.contentView.addSubview(remoteRenderer)

我认为 iPhone X 和 11s 的 WEBRTC 存在问题。我已经提交了错误报告 here。如果错误报告描述了您的问题，请务必启动它，以便 Google 可以解决它。谢谢！
