Do we need this to be a template? We'll just use these for cricket::VideoFrame
until we merge the two types right?

[nisse-webrtc, 2016/01/19 14:12:18]

I think some of the sink-like interfaces we want to replace use
webrtc::VideoFrame. So I guess it depends in whether or not we think the frame
types can be merged soon...

+class VideoSinkInterface {
+ public:
+  virtual void OnFrame(const VideoFrameT& frame) = 0;
+
+ protected:
+  ~VideoSinkInterface() {}
 };
 
 }  // namespace rtc

+#endif  // WEBRTC_MEDIA_BASE_VIDEOSINKINTERFACE_H_
