iOS13 Beta SKVideoNode + AVPlayer show black screen

Hi, my app is a AR app to play h.264 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.
