For streams using two different types of metadata, you might need additional
configuration setup depending on your player implementation. A stream can
contain multiple types of metadata. The IMA SDK adds metadata to the stream to
retrieve ad information from the media. For example,
[SCTE-35](https://support.google.com/admanager/answer/7506166) is a common second
metadata type.

For apps using
[Media3 ExoPlayer](https://developer.android.com/media/media3/exoplayer) v1.6 or
higher, streams with two metadata types are handled by default.

For apps using an ExoPlayer version lower than v1.6, you must add an additional
[`MetadataRenderer`](https://developer.android.com/reference/androidx/media3/exoplayer/metadata/MetadataRenderer)
instance to your ExoPlayer implementation. The following example adds a
second `MetadataRenderer` instance to support two metadata types:

```java
RenderersFactory defaultRenderersFactory = new DefaultRenderersFactory(context) {

  @Override
  protected void buildMetadataRenderers(Context context, MetadataOutput output,
      Looper outputLooper, @ExtensionRendererMode int extensionRendererMode,
      ArrayList<Renderer> out) {
    // Add a `MetadataRenderer` for each type of metadata. This example adds 2.
    out.add(new MetadataRenderer(output, outputLooper));
    out.add(new MetadataRenderer(output, outputLooper));
  }
};

new ExoPlayer.Builder()
    .setRenderersFactory(defaultRenderersFactory)
    .setMediaSourceFactory(mediaSourceFactory)
    .build();;
```
