Description Shijun Sun 2014-03-04 22:58:43 UTC 
In the Media Capture and Streams spec, deviceId is not registered as constraints, so apps can’t choose device based on the device enumeration.

Propose to connect deviceId and sourceId explicitly.  The following registration of sourceId in Section 14.1

The application-unique identifier for this source. The same identifier MUST be valid between sessions of this application, but MUST also be different for other applications. Some sort of GUID is recommended for the identifier.

should be appended as

The application-unique identifier for this source. The same identifier MUST be valid between sessions of this application, but MUST also be different for other applications. Some sort of GUID is recommended for the identifier.  A deviceId can be set as sourceId.

In the version http://dev.w3.org/2011/webrtc/editor/archives/20140507/getusermedia.html sourceId is a constraint. 

The names should be aligned.
Comment 2 Harald Alvestrand 2014-06-30 13:22:14 UTC 
Proposed resolution:

Replace 3 occurences of "deviceId" in section 9.3 "Device Info" with "sourceId".
Comment 3 Adam Bergkvist 2014-07-02 11:59:49 UTC 
That would mean that audio *output* devices would have a sourceId as well. It's a bigger change but deviceId would work better for both input and output devices.
