tvOS视频：如何在元数据上设置视频的持续时间

Question

I'm setting the title and description as metadata for an AVPlayer video in tvOS. How can set the player duration in metadata?

Answer 1

the info overlay should automatically display the correct duration. if not, you can try this:

let duration = player?.currentItem?.duration
let titleItem = AVMutableMetadataItem()

titleItem.key = AVMetadataCommonKeyTitle
titleItem.keySpace = AVMetadataKeySpaceCommon
titleItem.locale = NSLocale.currentLocale()
titleItem.value = "My Video"
titleItem.duration = duration
