Casty

Getting Started

Casty is a simple swift library used to make the integration of google cast sdk much simpler with few lines of code, it provides necessary functions to set and play your media right through to your chromecast by using google cast sdk.

Installation

Casty is available through CocoaPods. To install it, simply add the following lines to your Podfile:

pod 'google-cast-sdk'
pod 'Casty'

How to use

First thing import GoogleCast and Casty

import GoogleCast
import Casty

Then inside your AppDelegate class in didFinishLaunchingWithOptions

let appId = "12345678"
Casty.shared.setupCasty(appId: appId, useExpandedControls: true)

Now in ViewController class do the following:

• Initialize Casty

Casty.shared.initialize()

• Add casty button to your ViewController

let button = Casty.castButton
button?.tintColor = .red
let barButton = UIBarButtonItem(customView: button!)
navigationItem.rightBarButtonItem = barButton

• Load your media whenever session is started

let url = "https://commondatastorage.googleapis.com/gtv-videos-bucket/CastVideos/mp4/DesigningForGoogleCast.mp4"

let subtitleURL = "https://commondatastorage.googleapis.com/gtv-videos-bucket/CastVideos/tracks/DesigningForGoogleCast-en.vtt"


let subtitle = GCKMediaTrack(identifier: 1, contentIdentifier: subtitleURL , contentType: "text/vtt", type: GCKMediaTrackType.text, textSubtype: GCKMediaTextTrackSubtype.captions, name: "English", languageCode: "en", customData: nil)

//this image will show up in expanded controller as well as video thumb
let image = GCKImage(url: URL(string: "https://commondatastorage.googleapis.com/gtv-videos-bucket/CastVideos/images/780x1200/DesigningForGoogleCast-887x1200.jpg")!, width: 780, height: 1200)

Casty.didStartSession = { _ in
Casty.shared.loadMedia(url: self.url, subtitles: [subtitle], activeSubtitleID: 1, title: "Dev", image: image)
Casty.shared.presentExpandedController()
}

At this point you can see cast button icon whenever there is an active chromecast device and when you tap and connect a session, video will start to stream.

You can add default mini controller to your view controller

Casty.shared.addMiniController(toParentViewController: self)

To periodically get position of streaming video

Casty.enableMediaWatchPosition = true
Casty.mediaWatchPosition = { p in
print("position ----",p)
}

Important Notes

• Make sure you are connected to the same wifi network as chromecast

• For adaptive media streaming, Google Cast requires the presence of CORS headers, but even simple mp4 media streams require CORS if they include Tracks. If you want to enable Tracks for any media, you must enable CORS for both your track streams and your media streams. So, if you do not have CORS headers available for your simple mp4 media on your server, and you then add a simple subtitle track, you will not be able to stream your media unless you update your server to include the appropriate CORS header.

• If you want advanced features then I recommend you to use GoogleCast without casty
