Alex,
We have after complaints from our members tested this plugin with different browsers.
With Explorer 11, the plugin stops after making the selection of webcam (in this case only one webcam on a laptop) and we get a black screen and actually stops the plugin.
With Google Chrome, you immediately get a message that WebRTC is not possible.
With Edge, the plugin will work but is the image of the camera 90 degrees left turn.
On a smartphone (Samsung in this case) the plugin works perfectly.
Maybe this information can help you to improve this plugin.?
With best regards,
