Ranked in these QuestionsQuestion Ranking
Pro Needs no additional codecs
Everything MPlayer needs to play media files is contained within which means no outside codecs are needed.
Pro Nice theme available to choose from
Also, the video window is separate from the main window making it less cluttered while playing audio
Pro Easy shortcut keys
Quick skip ahead buttons and other shortcut keys.
Pro Based on GStreamer
It's based on the GStreamer framework so it supports all GStreamer codes and plugins.
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 Tries to be a Audio and Video player at the same time
So it will never be the perfect audio or video player
Con Menu navigation is poor
There are no icons inside the menus which makes them very uncomfortable and slow to browse.
Depending on your desktop environment it could have some huge dependencies for example it needs GStreamer and its codecs plus GTK and some Xfce libaries.
