如何在WEBRTC最新框架<Anakros/WebRTC>中使用videoview中显示localstream的方法？ - 用于 webrtc 框架(iOS)

Question

更新最新的 webrtc 框架后，我不知道如何向用户显示本地流，因为方法已更改，在存储库的 "iOS" 文件夹中没有示例。

旧代码...

   RTCVideoCapturer *capturer = [RTCVideoCapturer capturerWithDeviceName:cameraID];
   RTCMediaConstraints *mediaConstraints = [self defaultMediaStreamConstraints];
   RTCVideoSource *videoSource = [_factory videoSourceWithCapturer:capturer constraints:mediaConstraints];
   localVideoTrack = [_factory videoTrackWithID:@"ARDAMSv0" source:videoSource];

RTCVideoCapturer 对象和 RTCVideoSource 对象在此处相互链接。

但在新代码中...

  RTCVideoSource *source = [_factory videoSource];
  RTCCameraVideoCapturer *capturer = [[RTCCameraVideoCapturer alloc] initWithDelegate:source];
  [_delegate appClient:self didCreateLocalCapturer:capturer];
    localVideoTrack = [_factory videoTrackWithSource:source
                                             trackId:kARDVideoTrackId];

彼此没有联系。所以，委托方法做了什么， [_delegate appClient:self didCreateLocalCapturer:capturer]; 我不明白。 [需要帮助！]

Answer 1

在视频通话视图控制器中实现此委托方法....

- (void)appClient:(ARDAppClient *)client didCreateLocalCapturer:(RTCCameraVideoCapturer *)localCapturer{

    NSLog(@"%s %@",__PRETTY_FUNCTION__ ,localCapturer);

    _captureController =  [[ARDCaptureController alloc] initWithCapturer:localCapturer
                                                                settings:[[ARDSettingsModel alloc] init]];
    [_captureController startCapture];
}

然后....这个方法调用它来创建相同...

 - (RTCVideoTrack *)createLocalVideoTrack {
      RTCVideoTrack* localVideoTrack = nil;
      // The iOS simulator doesn't provide any sort of camera capture
      // trying to open a local stream.
    #if !TARGET_IPHONE_SIMULATOR
      if (![_settings currentAudioOnlySettingFromStore]) {
          RTCVideoSource *source = [_factory videoSource];
          RTCCameraVideoCapturer *capturer = [[RTCCameraVideoCapturer alloc] initWithDelegate:source];
          [_delegate appClient:self didCreateLocalCapturer:capturer];
          localVideoTrack = [_factory videoTrackWithSource:source
                                                   trackId:kARDVideoTrackId];

          [_delegate appClient:self didReceiveLocalVideoTrack:localVideoTrack];

      }

然后调用...

_localVideoTrack = [self createLocalVideoTrack];

在你的初始化方法中...

- (void)initCall {
    NSLog(@"%s",__PRETTY_FUNCTION__);
    if (!_isTurnComplete) {
        return;
    }
    self.state = kARDAppClientStateConnected;
    _localVideoTrack = [self createLocalVideoTrack];
    // Create peer connection.
    _constraints = [self defaultPeerConnectionConstraints];

}

我可以通过这段代码实现！
