Creating a simple instance of ExoPlayer

Question

I am currently looking to develop an application that utilises Dash through the ExoPlayer in Android.

To begin with I am going through the demo project however am ha

Here is how you would do it using the new ExoPlayer 2 API, and the SimpleExoPlayer.

First create the player:

DefaultBandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(context, bandwidthMeter);

TrackSelection.Factory videoTrackSelectionFactory = new AdaptiveTrackSelection.Factory(bandwidthMeter);
DefaultTrackSelector trackSelector = new DefaultTrackSelector(videoTrackSelectionFactory);
LoadControl loadControl = new DefaultLoadControl();

SimpleExoPlayer player = ExoPlayerFactory.newSimpleInstance(context, trackSelector, loadControl);

player.addListener(...); // To receive events from the player

Then create your MediaSource. For MP3 you can use ExtractorMediaSource:

ExtractorsFactory extractorsFactory = new DefaultExtractorsFactory();
Uri uri = Uri.parse(mp3UriString);
Handler mainHandler = new Handler(Looper.getMainLooper());
MediaSource mediaSource = new ExtractorMediaSource(uri, dataSourceFactory, extractorsFactory, mainHandler, mediaSourceListener); // Listener defined elsewhere

Then prepare and play when ready:

player.prepare(mediaSource);
player.setPlayWhenReady(true);

For DASH you would use DashMediaSource instead of ExtractorMediaSource.
