    // frames
};
[player seekToFrameAtIndex:5 loopCount:0];
[player play];

• Swift

let asset: AVAsset
let generator = AVAssetImageGenerator(asset: asset)
generator.appliesPreferredTrackTransform = true
generator.requestedTimeToleranceBefore = .zero
generator.requestedTimeToleranceAfter = .zero
// Player
let player = SDAnimatedImagePlayer(provider: generator)
player.animationFrameHandler = { (index, frame) in 
    // frames
}
