即使 IBOutlet 已连接，远程视频流也不会呈现到 UIView

Question

我似乎无法让远程视频流正确呈现到我的 UIView。我可以听到两个参与者的声音，但似乎无法呈现视频流，即使 IO.

知道为什么吗？这是我的代码：

func rtcEngine(_ engine: AgoraRtcEngineKit, firstRemoteVideoDecodedOfUid uid:UInt, size:CGSize, elapsed:Int) {

    DispatchQueue.main.async {

        if (self.remoteVideo.isHidden) {
            self.remoteVideo.isHidden = false
        }

        self.agoraKit.muteLocalAudioStream(false)

        let videoCanvas = AgoraRtcVideoCanvas()
        videoCanvas.uid = 0
        videoCanvas.view = self.remoteVideo
        videoCanvas.renderMode = .adaptive
        self.agoraKit.setupRemoteVideo(videoCanvas)

    }
}

从您的代码中，我看到您将 UID 分配为 0。这意味着它将自动为远程视图生成一个新的 UID。如果您愿意，可以将 UID 设置为 0 以自动生成本地视频流。但是，对于远程流，您需要获取回调方法的参数中提供的远程流的分配UID 作为uid 变量。

此外，您需要确保在采用 AgoraRtcEngineDelegate 协议的扩展中添加委托方法。

extension VideoChatViewController: AgoraRtcEngineDelegate {

    func rtcEngine(_ engine: AgoraRtcEngineKit, firstRemoteVideoDecodedOfUid uid:UInt, size:CGSize, elapsed:Int) {
        DispatchQueue.main.async {
            if (self.remoteVideo.isHidden) {
                self.remoteVideo.isHidden = false
            }
            self.agoraKit.muteLocalAudioStream(false)

            let videoCanvas = AgoraRtcVideoCanvas()
            videoCanvas.uid = uid
            videoCanvas.view = self.remoteVideo
            videoCanvas.renderMode = .adaptive
            self.agoraKit.setupRemoteVideo(videoCanvas)
        }
    }
}

即使 IBOutlet 已连接，远程视频流也不会呈现到 UIView

Remote video stream is not being rendered to the UIView even though the IBOutlet is connected
