IINA - Free and Open-Source Video Player

I have been installing VLC on computers at work for over 20 years, it's been a standard part of the image in K12 and higher ed schools for such a long time because it just works. You can throw just about any type of video file at it and VLC will play it. Whenever someone tries to use something else and runs into a problem, I generally won't help them unless they try to use VLC first. So, you can imagine that I was rather dubious when I first encountered IINA, a free and open-source video and audio player. I do have to admit that it is way better looking. VLC is still rocking that Windows XP vibe and IINA has a sleek, post-Yosemite native macOS design aesthetic. It is lovely to look at. When I looked into it, I found that it is a front end for two rock solid CLI video platforms ff-mpeg and mpv. It can play just about anything VLC can play.
