Exoplayer

note

You can find a fully functional sample app on our GitHub page: https://github.com/Broadpeak-tv/smartlib-android-sample-app

1. Attach the player​

When creating the player instance, attach it to the current session.

// Create your player
ExoPlayer player = new ExoPlayer.Builder(this).build();

// Attach your player to the current session
session.attachPlayer(player);

2. Start a streaming session​

The getURL method is used to get the actual streaming URL and start the streaming session. This method is also the starting point of the analytics calculation, for instance the startup time starts from this method.

The returned URL can be different for every video session. In case of using a Broadpeak CDN or a nanoCDN, it includes a unique token. It can be used only once per session object, once called the session is actually started.

When getURL returns an error, it means no streaming URL can be found. It has to trigger a specific behaviour on the application (error message, dialog...) and stopStreamingSession has to be called. Find more details about getURL errors on the session errors page.

It is recommended to perform this call on a different thread than the main thread, the method runs HTTP requests.

info

This method has to be called even for non-Broadpeak content URLs. In this case, the method will return the same URL.

// Start the session and get the final stream URL
StreamingSessionResult result = session.getURL(...);

if (!result.isError()) {
    // Load the stream URL into Exoplayer
    MediaItem item = new MediaItem.Builder()
        .setUri(Uri.parse(result.getURL()))
        .build();

    // Create the source
    DataSource.Factory dataSourceFactory = new DefaultDataSource.Factory(this);
    MediaSource source = new HlsMediaSource.Factory(dataSourceFactory) // If using HLS for instance
        .createMediaSource(item);
    source.addEventListener(yourHandler, (MediaSourceEventListener) session.getListener());

    // Set the source
    player.setMediaSource(source);
    player.prepare();

    // Play when ready
    player.setPlayWhenReady(true);
} else {
    // Stop the session
    session.stopStreamingSession();

    // Process the loading error
}

3. Stop a streaming session​

The stopStreamingSession method must be called each time the session is stopped:

  • end users: when the playback is stopped by a user action
  • loading errors: when the streaming session cannot be started through the getURL method
  • player errors: when the player triggers a non-recoverable error during the playback (as a decoding error)
  • application or any others actions: when the app is killed
// Stop the session
session.stopStreamingSession();
player.stop();

If the player generates a non-recoverable error during the playback (as a decoding error), call stopStreamingSession to stop the session.

player.addListener(new Player.Listener() {
    @Override
    public void onPlayerError(@NonNull PlaybackException error) {
        if (isNonRecoverableError(error)) {
            // Stop the session
            session.stopStreamingSession();
        }
    }
});
