Hello !

commit 1029fe intruduced a bug that prevents to choose a video capture device on the settings page.

Steps to reproduce the behavior:

1. Go to settings page
2. Specify any video capture device/capability
3. Start call
4. The application crashes

When starting a call right away everything is ok.

Details

The exception is thrown in the method PeerConnectionClient::addVideo at the line videoSource.start(); only if

videoSource.setVideoCaptureDevice(device);
videoSource.setVideoCaptureCapability(capability);

are executed. In other words it happens when device and capability are not null.

Desktop:

• OS: Ubuntu 20.10
• All necessary libs are installed: libasound2-dev libpulse-dev libudev-dev libv4l-dev
