it looks like there's no plan for this to be expanded as a larger class of its
own---does it makes sense to have this be a class, or should these methods just
be top-level helper methods in chromecast::media? (particularly now that the cma
code isn't just in the "media" namespace)

Same comments apply to other marshaller classes.

I wanted to group functions in the same way chrome ipc ParamTraits does (which
is also a set of static functions).
I plan to keep the same scheme.

+ public:
+  // Writes the serialized structure of |config| into |msg|.
+  static void Write(
+    const ::media::AudioDecoderConfig& config, MediaMessage* msg);

Done.

+
+  // Returns an AudioDecoderConfig from its serialized structure.
+  static ::media::AudioDecoderConfig Read(MediaMessage* msg);
+};
+
+}  // namespace media
+}  // namespace chromecast
