How can i get AVPlayer y position, height, width in AVPlayerLayer in objective c


I want to get position of video in AVPlayer x,y and height,width of display video in AVPlayerLayer.

enter image description here

My code is :

NSString *path = [[NSBundle mainBundle] pathForResource:@"Video" ofType:@"mp4"];
NSURL *url=[[NSURL alloc]initFileURLWithPath:path];
AVPlayer *av = [[AVPlayer alloc] initWithURL:url];
AVPlayerLayer *layer = [AVPlayerLayer playerLayerWithPlayer:av];
[layer setFrame:self.view.frame];
[self.view.layer addSublayer:layer];
[av play];

Solution

  • You can do like this.

        NSString *path = [[NSBundle mainBundle] pathForResource:@"Video" ofType:@"mp4"];
        NSURL *url=[[NSURL alloc]initFileURLWithPath:path];
    
        av = [[AVPlayer alloc] initWithURL:url];
        layer = [AVPlayerLayer playerLayerWithPlayer:av];
        [layer setFrame:self.view.frame];
        [self.view.layer addSublayer:layer];
        [av play];
    
        AVURLAsset *asset = [AVURLAsset URLAssetWithURL:url options:nil];
        NSArray *tracks = [asset tracksWithMediaType:AVMediaTypeVideo];
        AVAssetTrack *track = [tracks objectAtIndex:0];
        CGSize mediaSize = track.naturalSize;
    
    
    
        UIInterfaceOrientation orintation = [self orientationForTrack:asset];
    
        if (orintation == UIInterfaceOrientationLandscapeRight) {
            NSLog(@"UIInterfaceOrientationLandscapeRight");
            float videoWidth  = mediaSize.width;
            float videoHeight = mediaSize.height;
            float calVideoHeight =  (videoHeight * ScreenWidth)/videoWidth;
    
            NSLog(@"Video X      : 0");
            NSLog(@"Video Y      : %f",(ScreenHeight/2)-(calVideoHeight/2));
            NSLog(@"Video Width  : %f",ScreenWidth);
            NSLog(@"Video Height : %f",calVideoHeight);
        }
        else if (orintation == UIInterfaceOrientationLandscapeLeft) {
            NSLog(@"UIInterfaceOrientationLandscapeLeft");
            float videoWidth  = mediaSize.width;
            float videoHeight = mediaSize.height;
            float calVideoHeight =  (videoHeight * ScreenWidth)/videoWidth;
    
            NSLog(@"Video X      : 0");
            NSLog(@"Video Y      : %f",(ScreenHeight/2)-(calVideoHeight/2));
            NSLog(@"Video Width  : %f",ScreenWidth);
            NSLog(@"Video Height : %f",calVideoHeight);
        }
        else if (orintation == UIInterfaceOrientationPortraitUpsideDown) {
            NSLog(@"UIInterfaceOrientationPortraitUpsideDown");
            float videoWidth  = mediaSize.width;
            float videoHeight = mediaSize.height;
            float calVideoWidth =  (videoWidth * ScreenHeight)/videoHeight;
    
            NSLog(@"Video X      : 0");
            NSLog(@"Video Y      : 0");
            NSLog(@"Video Width  : %f",calVideoWidth);
            NSLog(@"Video Height : %f",ScreenHeight);
    
        }
        else if (orintation == UIInterfaceOrientationPortrait) {
            NSLog(@"UIInterfaceOrientationPortrait");
            float videoWidth  = mediaSize.width;
            float videoHeight = mediaSize.height;
            float calVideoWidth =  (videoWidth * ScreenHeight)/videoHeight;
    
            NSLog(@"Video X      : 0");
            NSLog(@"Video Y      : 0");
            NSLog(@"Video Width  : %f",calVideoWidth);
            NSLog(@"Video Height : %f",ScreenHeight);
        }
    
    
    - (UIInterfaceOrientation)orientationForTrack:(AVAsset *)asset {
        AVAssetTrack *videoTrack = [[asset tracksWithMediaType:AVMediaTypeVideo] objectAtIndex:0];
        CGSize size = [videoTrack naturalSize];
        CGAffineTransform txf = [videoTrack preferredTransform];
    
        if (size.width == txf.tx && size.height == txf.ty)
            return UIInterfaceOrientationLandscapeRight;
        else if (txf.tx == 0 && txf.ty == 0)
            return UIInterfaceOrientationLandscapeLeft;
        else if (txf.tx == 0 && txf.ty == size.width)
            return UIInterfaceOrientationPortraitUpsideDown;
        else
            return UIInterfaceOrientationPortrait;
    }
