    // create video url
    NSString *itemPath = [[NSBundle mainBundle] pathForResource:@"videoinfo0" ofType:@".mp4"];
    NSURL *url = [NSURL fileURLWithPath:itemPath];
 
    // create video object
    NVVideo *video = [[NVVideo alloc] initAVPlayerVideoWithURL:url];
    // set video size to screen
    [video setVideoRect:CGRectMake(0, 0, 1.0, 1.0)];
    // set filter
    [video changeFilter:SZTVR_PIXELATE];
    // add to render scene
    [self addRenderTarget:video];
    
    
    // create camera object
    NVCamera *camera = [[NVCamera alloc] initWithDevicePosition:CAMERA_BACK];
    [camera setVideoRect:CGRectMake(0.5, 0.5, 0.5, 0.5)];
    [camera changeFilter:SZTVR_NORMAL];
    [self addRenderTarget:camera];
}

recoder video

 - (void)initRecodeUtil
 {
     // create recode handle
     self.recodeUtil = [[NVRecord alloc] initWithRecodeName:[NSString stringWithFormat:@"recode_demo"]];
     self.recodeUtil.renderTarget = [self getSurfaceBuffer];
     self.recodeUtil.delegate = self;
 }
 
     // method
     [self.recodeUtil startRecording];
     
     [self.recodeUtil endRecording];
