namespace media {

Since most our media code are under ::chromecast::media namespace

I half-remember a discussion about whether to put public APIs directly in
::chromecast ... @lcwu + @gunsch do you remember if we reached a conclusion on
that?

I don't remember a discussion on what namespace(s) to use, but I agree that it
makes sense to use chromecast::media namespace here to further/better segregate
the names.

+class CHROMECAST_EXPORT CastMediaShlib {
+ public:
+  // Performs platform-specific one-time initialization for media systems and
+  // hardware resources. Called at startup in browser process before main
+  // message loop begins.
+  static void Initialize(const std::vector<std::string>& argv);
+
+  // Performs platform-specific one-time teardown of media systems and hardware
+  // resources. Called at browser process exit.
+  static void Finalize();
+};
+
+}  // namespace chromecast
+
+#endif  // CHROMECAST_PUBLIC_CAST_MEDIA_SHLIB_H_
