<p>
If the renderer's state is <a href="../../../../com/google/android/exoplayer/TrackRenderer.html#STATE_STARTED"><code>TrackRenderer.STATE_STARTED</code></a>, then repeated calls to this method should
cause the media track to be rendered. If the state is <a href="../../../../com/google/android/exoplayer/TrackRenderer.html#STATE_ENABLED"><code>TrackRenderer.STATE_ENABLED</code></a>, then repeated
calls should make progress towards getting the renderer into a position where it is ready to
render the track.

This method should return quickly, and should not block if the renderer is currently unable to
make any useful progress.
