In getUserMedia(), make sure a request has titles of devices which user can choose from.

• Component: WebCore Misc.
• Status: RESOLVED INVALID

[Matthew Daiter]

When presenting getUserMedia, the user should be informed of the device he or she is opening. This patch enables the passing of a list of strings from WebCore to WebKit2, enabling browsers to pull an available list of devices so a user can see options from which he or she can choose.

Is this necessary to get titles?

If so, this code is cross platform so I think you need to add a new virtual method to RealtimeMediaSourceCenter that calls [platform manager].getSourcesInfo()

Ditto, but for verifyConstraintsForMediaType.

Ditto.

This is handled elsewhere.
