mpv will play everything I want but it doesn't have a gui. It does have ability for customizing keyboard shortcuts with a configuration file. Celluloid is a gui front end for mpv and solves some of my problems and it can use mpv configuration files.
A few years ago I installed Smplayer and hated the default gui with the giant toolbar and status bar. I didn't poke around enough to learn about it and just avoided it. I think it changed a lot since then.
The past few days I installed Smplayer and VLC again. I didn't realize I could customize most of the keyboard shortcuts and the gui on both. I changed some of the keyboard shortcuts so the ones I am used to are the same as the default ones in mpv.
Then I made the guis look almost like Celluloid.
