Pro Needs no additional codecs

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 Up to date
Always up to date, rapid development.
Pro Extremely responsive
Pro Caches livestreams
Intelligently caches livestreams and enables jumping within the cached stream.

Cons
Con Not much documentation on the use and configuration
Con Contrary to review, some media that play well in vlc does not play in mplayer
Con Doesn't support directory playback
Con Lacks a built-in visualizer
Con Minimal theme support
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.
