I would like to create a "virtual camera" that can be used with 3rd party apps such as Zoom or Skype, browser etc. In the same way these can work with a virtual camera app such as Snap.
I want to take the feed from the built in webcam on the laptop, make some changes to it e.g. brightness, then be able to select in Zoom, Skype, browser, my edited feed.
So far I have written something as a Universal Windows Platform app that takes the webcam feed, applies my processing to it, and shows it in a window. For that I have used the Windows Media API. https://learn.microsoft.com/en-us/uwp/api/windows.media.effects?view=winrt-19041
Can anyone point me in the right direction of how to take this modified feed and make available to Zoom, Skype, browsers? I've seen a lot of stuff related to DirectShow but nothing that fully makes sense or that has been written in the last 6 or 7 years. What would be the best way to do this in 2020, with C#?
Many thanks
