User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/48.0.2564.97 Safari/537.36

Steps to reproduce:

In webrtc, when I call getusermedia with constraints included device ids(canera,mic), then do renegotiations. 


Actual results:

Whatever device id is firefox set selected device in its own popout window(attached in files). I cant change device usgin getusermedia with constraints,I have to change device from firefox popout.


Expected results:

Current devices have to be selected ids whic given in constraints.we have to no need to firefox popout.

Can you be more explicit on what you're doing, and what happens that you don't want/expect?  Examples would be best, or code snippets, or an indication what calls you make with what arguments.

Renegotiation itself shouldn't pop a new GetUserMedia approval request; only a new GetUserMedia call would do that.

We made a new getusermedia call, we set device id that we want to use in constraints. we want set devices with getusermedia not a popout. but firefox show us a popout every getusermedia call.

Passing a device-id is not a substitute for user approval of access.  Chrome hides this by making the default to approve permanently.  We could perhaps allow access to a device you already have access to without re-asking without violating the spec (or violating the spirit) -- but on the other hand, you have no need/reason to do so - just reuse the existing stream.

I.e. don't call getUserMedia on renegotiation - that's in incorrect pattern, even if it happens to work ok in Chrome.  Just use the current stream again to the new offer/answer.
