This isn't quite accurate... this only affects MediaStream so how about:

kEnableWebMediaPlayerMS[] = "enable-web-media-player-ms" ?

That way in RenderViewImpl the switch will very closely resemble the code (i.e.,
if kEnableWebMediaPlayerMS is true then we create an object called
WebMediaPlayerMS)

Done.
