<a href="https://www.chromacam.me" rel="nofollow">https://www.chromacam.me</a> basically lets you greenscreen directly into a vidchat program without the need for a) a greenscreen and b) associated streaming software like obs etc. It acts as a second webcam and you select that instead of your actual webcam in video permissions. It works with other video chat programs like skype, but isn't supported here yet. It would make streaming through Roll20 a lot cleaner / easier / more professional and seems made specifically for video chat applications so hopefully Roll20 could implement support for it?
