Can only capture from a single microphone at a time

Reported by randell....@gmail.com, Nov 15 2012

Issue description

What steps will reproduce the problem?
1. Capture from microphone 1 via ptrVoEHw->SetRecordingDevice(index1)
2. Capture from microphone 2 via ptrVoEHw->SetRecordingDevice(index2)

What is the expected result?
Two streams of captured data from different microphones would be nice

What do you see instead?
It stops recording the first device (see VoEHardwareImpl::SetRecordingDevice())


What version of the product are you using? On what operating system?
3.12 branch (stable).  Linux (though this applies to all)

I think this is expected. 
A number of usecases for getUserMedia rely on multiple simultaneous inputs (camera or mic).  Currently, if you want to support more than one stream of a media type using the webrtc.org codebase, you want to create two separate instances of the entire stack, which is sub-optimal and also may make synchronizing them painful (or at least annoying).

Is this still a valid bug?

As stated earlier, it is not a bug but a known (by design) limitation. Assigning an owner but no work is planned currently.
