A library and clients to stream Twitch live streams to an Airplay device.

There is only one client provided, an CLI application. A graphiccal UI is planned.

The AirTwitch library (project airtwitch-core) provides two entry points.

To get devices, simply start the service discovery and register a listener.

AirPlayServiceDiscovery.registerListener(device -> System.out.println("Found device: " + device.getName());

The listener will be called every time a new device is dicovered. Remember to shut down the discovery when ending the application. It starts a daemon thread which will prevent the JVM from terminating.

AirPlayServiceDiscovery.close();

The Twitch API provides a slim section of the full API, just enough to get the live streams of a channel. Remember to get the channel token before accessing the stream list.

Twitch twitch = new Twitch();
List<Channel> channels = twitch.searchChannels("stream name");
//or
Channel channel = twitch.getChannelById(12345);

channel.requestChannelToken();
List<LiveStream> streams = channel.getLiveStreams();

To start playback, simply pass the stream URI to the device:

StreamControl streamControl = device.createStream(stream.getStreamUri());
streamControl.play();
//wait...
streamControl.stop();

Start the client by running the JAR. Type help to print help information.

Select a device by going to the device cubment (enter d or device) and select a device from the list. Type exit to return to the main menu.

Search for a stream by going to the stream menu (enter s or stream) and search for a channel using the search command (e.g. search mychannel). Select the channel and stream you want to watch and type exit to return to the main menu.

Finally you can start the stream using the play command. Press the enter key to terminate the stream and exit to leave the application.

To run, the application needs a Twitch Client ID for calls to the Twitch API. You can create it on the connections page of your Twitch account. Register a new developer application on the bottom of that page.

To provide the ID to the application, you have four options:

1. Provide it as Java system property twitchClientId
2. Provide it as environment variable TWITCH_CLIENT_ID
3. Provide it in a file named twitch_client_id in the classpath of the application.

You can also include it in the built application, see the build section below.

Clone the repository, then run mvn clean package to build the library and the clients.

To include the Twitch Client ID in the final application, simply set the environment variable TWITCH_CLIENT_ID before starting the build. It will be automatically included.
