Can you make this an enum class?

Done.

style nit: Inline accessors should be in lowercase:

  MediaRemotingStatus media_remoting_status() const {...}

[mlamouri (slow - plz ping), 2017/04/13 17:20:51]

Unfortunately, this isn't true in Blink even after the new style:

[xjz, 2017/04/13 19:12:11]

Thanks for clarification. 

[xjz, 2017/04/13 19:12:11]

Kept it unchanged according to the Blink style.
