WEBRTC(iOS):本地视频没有在遥控方面流动

Question

我正在尝试使用webrtc进行音频，视频调用。

远程视频和音频在我的应用中正常工作，但是我的本地流并未出现在客户端。

这是我为添加视频曲目

而写的。

let videoSource = self.rtcPeerFactory.videoSource()
let videoCapturer = RTCCameraVideoCapturer(delegate: videoSource)
guard let frontCamera = (RTCCameraVideoCapturer.captureDevices().first { $0.position == .front }),
    // choose highest res
    let format = (RTCCameraVideoCapturer.supportedFormats(for: frontCamera).sorted { (f1, f2) -> Bool in
        let width1 = CMVideoFormatDescriptionGetDimensions(f1.formatDescription).width
        let width2 = CMVideoFormatDescriptionGetDimensions(f2.formatDescription).width
        return width1 < width2
    }).last,
    // choose highest fps
    let fps = (format.videoSupportedFrameRateRanges.sorted { return $0.maxFrameRate < $1.maxFrameRate }.last) else {
        print(.error, "Error in createLocalVideoTrack")
        return nil
}
videoCapturer.startCapture(with: frontCamera,
                           format: format,
                           fps: Int(fps.maxFrameRate))

self.callManagerDelegate?.didAddLocalVideoTrack(videoTrack: videoCapturer)
let videoTrack = self.rtcPeerFactory.videoTrack(with: videoSource, trackId:  K.CONSTANT.VIDEO_TRACK_ID)

这是添加音轨

let constraints: RTCMediaConstraints = RTCMediaConstraints.init(mandatoryConstraints: [:], optionalConstraints: nil)
let audioSource: RTCAudioSource = self.rtcPeerFactory.audioSource(with: constraints)
let audioTrack: RTCAudioTrack = self.rtcPeerFactory.audioTrack(with: audioSource, trackId: K.CONSTANT.AUDIO_TRACK_ID)

我的完整webrtc日志在这里。

我得到的一些日志(我认为这是错误的(
