Playing Live Video Captures on Linux

Is there any way to take a live video feed from my webcam and play it directly inside UE4 on Linux?

I have followerd this document:…ams/index.html

But, the Capture Devices button on MediaPlayer asset is empty, looks like there is no support for V4L2

How should I write the Media URL on Linux?

I am running into this exact same problem, has anyone found a solution?
I’ve tried manually entering vidcap:///dev/video0 but it does not work.
