libmpv is used in a wide variety of user friendly players.

When people say "use mpv", its like "use Linux". Generally speaking you aren't doing much with the Linux kernel, you need the rest of the tools around it to make it friendly.

No difference here - grab one of the many players that use mpv under the hood. mpv.net, smplayer, iina, moonplayer, haruna, mpvex, etc, etc.
