Pro Needs no additional codecs
Everything MPV needs to play media files is contained within which means no outside codecs are needed.
Pro Minimal interface
Click to open files and get Video with sound (and passthrough of codecs like DTS etc) for a perfect cinema experience. Works okay for many files.
Default window is not much more than a title bar - and if you drag/resize the window it resizes the video and leaves no empty areas. There is no visible control or display unless you use mouse/keyboard over the window.
This is the best player to use unless you're going for a media center (then use MPV based Plex Media Player to display and play the Plex Server library).
Pro Integrates with streaming services
When used with youtube-dl.
Pro Extremely responsive
Pro Caches livestreams
Intelligently caches livestreams and enables jumping within the cached stream.
Pro Up to date
Always up to date, rapid development.
Con Lack of a typical GUI can be jarring to some
The minimal interface comes at the cost of beginner-friendliness. You need to know keyboard shortcuts by heart, settings are set in text files, right-clicking won't bring up a menu, etc.
