getUserMedia doesn't accept preferred height and width constraints about webrtc-plugin

[DoubangoTelecom]

Fix is part of the installer version 1.2.0: https://doubango.org/rtc-plugin/setup.exe
Please note that according to https://www.w3.org/TR/mediacapture-streams/#idl-def-MediaStreamConstraints, the constraints you're using to test the 'exact' usecase isn't correct. Both Chrome and IE are ignoring it (see chrome://webrtc-internals/).
You're using: { audio: true, video: { exact: { height: 1920, width: 1080 } } }
Should be: { audio: true, video: {width: {exact: 1080}, height: {exact: 1920}} }
