Jitsi VideoBridge and flash-videoio

I know that you relay on WebRTC, but as long, as WebRTC is not supported by all major web browser (unfortunately including Internet Explorer) I need to something more universal. So it’s my question - is there possibility to use a flash-videoio with Jitsi VideoBridge? I don’t have idea, how to set src of flash-videoio.

No. Jitsi Videobridge does not support flash

But I found something interesting, but it’s commercial solution - https://www.frozenmountain.com/products/icelink. I plan check it in some my free time.
