Is this class meant to be copyable? Usually Blink classes invoke
WTF_MAKE_NONCOPYABLE

I only see such macro used in Source/, there's no such
reference in any public/platformWebMediaStream* file
(actually nowhere in public/).

+public:
+    virtual ~WebMediaRecorderHandler() { }
+    virtual bool canSupportMimeType(const WebString& mimeType) = 0;
+    virtual bool initialize(WebMediaRecorderHandlerClient*,
+                            const WebMediaStream&,
+                            const WebString& mimeType) = 0;
+    virtual bool start() = 0;
+    virtual bool start(int timeslice) = 0;
+    virtual void stop() = 0;
+    virtual void pause() = 0;
+    virtual void resume() = 0;
+};
+
+} // namespace blink
+#endif
