+// MediaPlayerRenderer wraps a MediaPlayerBridge (itself a wrapper for an
+// Android MediaPlayer). MediaPlayerRenderer adapts the MediaPlayer's API and
+// state, exposing it as the media::Renderer interface instead.
+//
+// MediaPlayerRenderer forwards appropriate callbacks to the given
+// RendererClient.
+//
+// MediaPlayerRenderer also implements MediaPlayerManager, since
+// MediaPlayerBridge is tightly coupled with the abstraction.
+// |player_id| is ignored in all MediaPlayerManager calls, as the
+// MediaPlayerRenderer has a 1:1 mapping with a MediaPlayer.
+// TODO(tguilbert): Once it is safe to remove WMPA code,
+// MediaPlayerRenderer should directly implement the relevant methods
+// called back by MediaPlayerBridge, instead of using the MediaPlayerManager
+// interface. See http://crbug.com/580626
+//
+// N.B: This class is still a work in progress.
