从 URL 播放视频并同时通过摄像头录制视频 - Objective C

Question

我正在尝试构建一个可以从 URL 播放视频并同时使用前置摄像头录制视频的应用程序。我试过了，但是当相机开始捕捉时视频停止播放，反之亦然。请帮帮我。提前致谢！！ 这是我的代码，我正在使用 DIYCam（使用 AVFoundation）框架，完美录制并使用 AVPlayer 播放

- (IBAction)startRecording:(id)sender {
self.cam = [[DIYCam alloc] initWithFrame:CGRectMake(0, 0, 320, 300)];
self.cam.layer.anchorPoint = CGPointMake(0.f, 0.f);
self.cam.frame = CGRectMake(0, 0, 320, 300);
self.cam.delegate       = self;
[self.cam setupWithOptions:nil];
[self.cam setCamMode:DIYAVModeVideo];
self.cam.backgroundColor = [UIColor greenColor];
[self.cam captureVideoStart];

}

-(void)playVideo {

NSURL *url = [[NSBundle mainBundle] URLForResource:@"responcevideo"
                                     withExtension:@"mp4"
                                      subdirectory:nil];
AVPlayer *_avPlayer;
_avPlayer = [AVPlayer playerWithURL:url] ;

AVPlayerLayer *_avPlayerLayer = [AVPlayerLayer playerLayerWithPlayer:_avPlayer];

_avPlayerLayer.frame = self.view.layer.bounds;
[self.view.layer addSublayer:_avPlayerLayer];

[_avPlayer play];

}

尝试在不同的线程上运行录制和播放视频。
