I use an OBS (Streamlabs OBS) to stream games. A month ago I learned that I could use the Virtual Webcam option on the OBS to stream a digital deck on Moxfield or Archideckt to spelltable. So, instead of my desktop camera being used to stream my actual cards so all players could see my cards, I learned I could stream my digital versions of the deck from a deckbuilding site strain to spelltable.

A month ago, this worked fine. No issues. However, I tried it again today and instead I get a black screen. When going into a spelltable game I make sure to click on the cogwheel and choose "Streamlabs Desktop Virtual Webcam" for the Camera Source. However, it is just showing up blank as you see in the screenshot.

In the screen shot you see my spelltable on the left and the screen is blank. The screen on the right is my OBS software. It should be showing what is seen on the OBS software screen on the spelltable screen. If I was on Moxfield you would see my Moxfield playtest screen on the OBS software screen on that right side.

Anyways, I worry some update or change on your end has disabled my ability to use a Virtual Webcam from my OBS software so that I can stream my digital deck from Moxfield.com or Archidekt.com.
