Hi, my app is a AR app, we use Vuforia to recognize image and use SceneKit to play video.

We created SKVideoNode by AVPlayer and set the SKVideoNode to SKScene, and then create SCNNode to involve this SKScene.

- Sample Code

========================

    AVPlayer *avPlayer = [self getMoviePlayer:path];

    SKVideoNode *videoNode = [[SKVideoNode alloc]initWithAVPlayer: avPlayer];

    CGSize videoSize = CGSizeMake(100, 50);

    videoNode.size = videoSize;

    videoNode.position = CGPointMake(50, 50);

    videoNode.yScale = -1.0;

    SKScene *skScene = [[SKScene alloc] initWithSize:videoSize];

    skScene.scaleMode = SKSceneScaleModeAspectFit;

    [skScene addChild:videoNode];

    SCNNode *planeNode = [[SCNNode alloc] init];

    planeNode.geometry =  [[SCNPlane alloc] init];

    SCNMaterial *material;

    material = [[SCNMaterial alloc] init];

    material.diffuse.contents = skScene;

    planeNode.geometry.firstMaterial = material;

========================

    we use this SCNNode to play videos.

it works fine until iOS12.4 but when I test it on iOS13-beta device, it shows black screen while sound is heard.
