tvOS AVPlayerViewController Video Info

The accepted answer is correct. We can use AVMutableMetadataItem to provide video related information.

But if you need to have more options in player menu, it is better to create a UIViewController with custom information and settings option [based on your requirement] and set it as AVPlayerViewController's customInfoViewController.

This is available from tvOS 11.0

Official apple docs on this: Apple Docs Link

To get the "Info" section to show up in the "Swipe down for info" pane in AVPlayerViewController you create AVMutableMetadataItems with the AVMetadataKeySpaceCommon keyspace and any of the following keys:

AVMetadataCommonKeyTitle
AVMetadataCommonKeyDescription
AVMetadataiTunesMetadataKeyContentRating
AVMetadataQuickTimeMetadataKeyGenre

and add them to the AVPlayerItem's externalMetadata array. In order for each AVMutableMetadataItem to show up you must at least set the identifier, extendedLanguageTag, and value properties. Here's an example:

let mediaItem = AVPlayerItem(URL: mediaURL)

let titleMetadataItem = AVMutableMetadataItem()
titleMetadataItem.locale = NSLocale.currentLocale()
titleMetadataItem.key = AVMetadataCommonKeyTitle
titleMetadataItem.keySpace = AVMetadataKeySpaceCommon
titleMetadataItem.value = "The Title"

let descriptionMetadataItem = AVMutableMetadataItem()
descriptionMetadataItem.locale = NSLocale.currentLocale()
descriptionMetadataItem.key = AVMetadataCommonKeyDescription
descriptionMetadataItem.keySpace = AVMetadataKeySpaceCommon
descriptionMetadataItem.value = "This is the description"

mediaItem.externalMetadata.append(titleMetadataItem)
mediaItem.externalMetadata.append(descriptionMetadataItem)

This isn't well-documented. This forum post was critical to figuring this out.

Objective-C example for @JenelEjercitoMyers:

AVPlayerItem *mediaItem = [[AVPlayerItem alloc] initWithURL:mediaURL];

AVMutableMetadataItem *titleMetadataItem = [[AVMutableMetadataItem alloc] init];
titleMetadataItem.locale = NSLocale.currentLocale;
titleMetadataItem.key = AVMetadataCommonKeyTitle;  
titleMetadataItem.keySpace = AVMetadataKeySpaceCommon;  
titleMetadataItem.value = @"The Title";

NSArray *externalMetadata = [[NSArray alloc] initWithObjects:titleMetadataItem, nil];

mediaItem.externalMetadata = externalMetadata;
