Question

我在尝试使DeepAR的口罩出现在我的Agora视频通话中时遇到问题。我遵循了这个Github repo，但是当我设置它们对videoEncoderCOnfiguration和startFrameOutput的设置方式时，它对我来说很崩溃：

 func setupVideo() {

    agoraKit.setExternalVideoSource(true, useTexture: true, pushMode: true)
    agoraKit.enableVideo()
    agoraKit.disableAudio()

    agoraKit.setVideoEncoderConfiguration(AgoraVideoEncoderConfiguration(size: AgoraVideoDimension640x360,
                                                                         frameRate: .fps15,
                                                                         bitrate: AgoraVideoBitrateStandard,
                                                                         orientationMode: .adaptative))
}
func joinChannel() {

    agoraKit.joinChannel(byToken: nil, channelId: "demoChannel1", info: nil, uid: 0) { [unowned self] (channel, uid, elapsed) -> Void in
        // Did join channel "demoChannel1"
        UIApplication.shared.isIdleTimerDisabled = true
        self.localVideoView.startFrameOutput(withXmin: 0, xmax: 1, ymin: 0, ymax: 1, scale: 1)
        self.localVideoView.isHidden = false
    }
}

在self.arView.startFrameOutput(withXmin: 0, xmax: 1, ymin: 0, ymax: 1, scale: 1)行之后，应用程序崩溃并显示此消息

*由于未捕获的异常'NSInvalidArgumentException'而终止应用程序，原因：'* -[__ NSArrayM insertObject：atIndex：]：对象不能为空'

当我根据如下所示的常规Agora呼叫回购设置呼叫时，该应用程序本身运行正常，但是即使我在可以正常工作的控制台中打印遮罩，我也无法在视频中看到遮罩。

func setupVideo() {

    rtcEngine.enableVideo()

    let canvas = AgoraRtcVideoCanvas()
    canvas.uid = 0
    canvas.view = localVideoView
    canvas.renderMode = .hidden
    rtcEngine.setupLocalVideo(canvas)

}

func joinChannel(channelId: String, token: String, uid: UInt) {
    rtcEngine.joinChannel(byToken: token, channelId: channelId, info: nil, uid: uid) { (sid, uid, elapsed) in
        self.callAnswered = true
        self.showButtonsIfCallIsAnswered()
        self.localVideoView.isHidden = false

    }
    UIApplication.shared.isIdleTimerDisabled = true
}

问题是即使控制台正在打印出该值，我也看不到掩码。当我像在DeepAR和Agora的仓库中那样设置外部视频源时，该应用程序在加入后立即崩溃。

我真的很感谢有人帮助我进行调试，以便所有操作都能顺利进行：）

将DeepAR蒙版应用于Agora视频通话iOS
