ExoPlayer supports SmoothStreaming with the FMP4 container format. Media streams must be demuxed, meaning that video, audio and text must be defined in distinct StreamIndex elements in the SmoothStreaming manifest. The contained audio and video sample formats must also be supported (see the sample formats section for details).

Using MediaItem

To play a SmoothStreaming stream, you need to depend on the SmoothStreaming module.

implementation ''

You can then create a MediaItem for a SmoothStreaming manifest URI and pass it to the player.

// Create a player instance.
SimpleExoPlayer player = new SimpleExoPlayer.Builder(context).build();
// Set the media item to be played.
// Prepare the player.

If your URI doesn’t end with .ism/Manifest, you can pass MimeTypes.APPLICATION_SS to setMimeType of MediaItem.Builder to explicitly indicate the type of the content.

ExoPlayer will automatically adapt between representations defined in the manifest, taking into account both available bandwidth and device capabilities.

Using SsMediaSource

For more customization options, you can create a SsMediaSource and pass it directly to the player instead of a MediaItem.

// Create a data source factory.
DataSource.Factory dataSourceFactory = new DefaultHttpDataSourceFactory();
// Create a SmoothStreaming media source pointing to a manifest uri.
MediaSource mediaSource =
    new SsMediaSource.Factory(dataSourceFactory)
// Create a player instance.
SimpleExoPlayer player = new SimpleExoPlayer.Builder(context).build();
// Set the media source to be played.
// Prepare the player.

Accessing the manifest

You can retrieve the current manifest by calling Player.getCurrentManifest. For SmoothStreaming you should cast the returned object to SsManifest. The onTimelineChanged callback of Player.Listener is also called whenever the manifest is loaded. This will happen once for a on-demand content, and possibly many times for live content. The code snippet below shows how an app can do something whenever the manifest is loaded.

    new Player.Listener() {
      public void onTimelineChanged(
          Timeline timeline, @Player.TimelineChangeReason int reason) {
        Object manifest = player.getCurrentManifest();
        if (manifest != null) {
          SsManifest ssManifest = (SsManifest) manifest;
          // Do something with the manifest.

Customizing playback

ExoPlayer provides multiple ways for you to tailor playback experience to your app’s needs. See the Customization page for examples.
