Looks like all of this belongs in the same place as were you have the audio
capturer - ie move to a function in dependency_factory_ that
takes(*request_it)->descriptor as argument.

Done.

So is StopStream only used for video now or audio as well?

[no longer working on chromium, 2013/03/20 15:10:19]

both audio and video as before.
