Windows 10 Media Feature Pack?

I’ve been unable to get camera working in Jitsi since reinstalling Windows, and several users have complained of this as well.
After a bunch of troubleshooting, I discovered that I needed Windows 10 Media Feature Pack installed [KB3145500], and then it started working.
All other video conference software worked (Google Hangouts Meet, Zoom, Microsoft Teams) prior to installing this media pack.
I’m not sure how I ended up without those features installed, or why other software was able to access my camera without it, but this might be something that other users are struggling with, and if there’s a way to make sure that people don’t have to rely on this pack, then it will assure better/broader compatibility.
