How to add/use GCKMediaQueue in Swift? - ios

Question

So I have managed to play a video on Chromecast. But only one at a time. I've been trying to figure how to programmatically add to the queue. The idea is to keep playing videos all day. In the code below "playthisvideo()" randomly returns a string that contain an http://.....mp4 . I've look at Google's documentation, it's either too vague or I just don't understand it. And I can't seem to find any examples that would lead the way for me to follow.
func castthevideo() {
let metadata = GCKMediaMetadata()
metadata.setString("Los Simpsons", forKey: kGCKMetadataKeyTitle)
metadata.setString ("Barista: ¿Cómo tomas tu café? " +
" Yo: Muy, muy en serio.",
forKey: kGCKMetadataKeySubtitle)
metadata.addImage(GCKImage(url: URL(string: "https://m.media-amazon.com/images/M/MV5BYjFkMTlkYWUtZWFhNy00M2FmLThiOTYtYTRiYjVlZWYxNmJkXkEyXkFqcGdeQXVyNTAyODkwOQ##._V1_.jpg")!,
width: 480,
height: 360))
let PTV = playthisvideo()
let url = URL.init(string: PTV)
print ("****** ", PTV)
guard let mediaURL = url else {
print("****** invalid mediaURL")
return }
//let mediaInfoBuilder = GCKMediaInformationBuilder.init(contentURL: mediaURL)
let mediaInfoBuilder = GCKMediaInformationBuilder.init(contentURL: mediaURL)
mediaInfoBuilder.streamType = GCKMediaStreamType.none;
mediaInfoBuilder.contentType = "video/mp4"
mediaInfoBuilder.metadata = metadata;
let mediaInformation = mediaInfoBuilder.build()
if let request = sessionManager.currentSession?.remoteMediaClient?.loadMedia(mediaInformation) { request.delegate = self }
GCKCastContext.sharedInstance().presentDefaultExpandedMediaControls()
}
func castanthor(byAppending appending: Bool) {
let PTV = playthisvideo()
let url = URL.init(string: PTV)
guard let mediaURL = url else {
print("invalid mediaURL")
return
}
myNSNumber = (1 as NSNumber)
if let remoteMediaClient = GCKCastContext.sharedInstance().sessionManager.currentCastSession?.remoteMediaClient {
let builder = GCKMediaQueueItemBuilder()
builder.mediaInformation = selectedItem.mediaInfo
builder.autoplay = true
builder.preloadTime = 3
let item = builder.build
if remoteMediaClient.mediaStatus != nil, appending {
let request = remoteMediaClient.queueInsert(item(), beforeItemWithID: kGCKMediaQueueInvalidItemID)
request.delegate = self
} else {
let options = GCKMediaQueueLoadOptions()
options.repeatMode = remoteMediaClient.mediaStatus?.queueRepeatMode ?? .off
let request = castSession.remoteMediaClient?.queueLoad([item()], with: options)
request?.delegate = self
}
}}

var mediaItems = [GCKMediaQueueItem]()
var urls = // Array of only audio and videos
for index in 0..<urls.count {
let builder = GCKMediaQueueItemBuilder()
let mediaInfoBuilder = GCKMediaInformationBuilder.init(contentURL: urls[i])
mediaInfoBuilder.streamType = GCKMediaStreamType.none;
mediaInfoBuilder.contentType = "video/mp4"
mediaInfoBuilder.metadata = metadata;
let mediaInformation = mediaInfoBuilder.build()
builder.mediaInformation = mediaInformation
builder.autoplay = true
builder.preloadTime = 3
let item = builder.build
mediaItems.append(item)
}
if let remoteMediaClient = GCKCastContext.sharedInstance().sessionManager.currentCastSession?.remoteMediaClient {
let loadOptions = GCKMediaQueueLoadOptions()
loadOptions.repeatMode = .all
loadOptions.startPosition = 0
remoteMediaClient.queueLoadItems(mediaItems, withOptions:loadOptions)
}
