I think we would need to change this API to accept device id. We do not use
Audio[Video]RendererSink for chromecast.

I would also get rid of MojoMediaClient::CreateAudio[Video]RendererSink and make
the usage of RendererFactory internal to MojoMediaClient implementation.

I agree it seems the time to address the comment/TODO at l.51 now.

Done.  Added CreateRender api.  Removed CreateRendererFactory and
CreateAudio[Video]RendererSink apis.

       const scoped_refptr<MediaLog>& media_log);
 
   // The output sink used for rendering audio or video respectively. They will
   // be used in the CreateRenderer() call on the RendererFactory returned by
   // CreateRendererFactory(). May be null if the RendererFactory doesn't need an
   // audio or video sink. If not null, the sink must be owned by the client.
-  virtual AudioRendererSink* CreateAudioRendererSink();
+  virtual AudioRendererSink* CreateAudioRendererSink(
+      const std::string& device_id);
