Good point, however as I mentioned, most mobile devices wont let us open more than one camera at a time, which is problematic when the spec demands the hardware be open already. i.e. How can we open first the front camera, then close it to open the back camera and then send out combined SDP for both upfront? .: Jan-Ivar :.
