Quickly going through a directory with too many loadable files causes the autoload tasks to pile up and exiting the player will take forever. Avoid this by skipping loading when playback is aborted.
mpv lua scripts
The lua scripts in this folder can be loaded on a one-time basis by adding the option
--script=/path/to/script.lua
to mpv's command line.
Where appropriate, they may also be placed in ~/.config/mpv/scripts/ from where they will be automatically loaded when mpv starts.
This is only a small selection of internally maintained scripts. Some of them are just for testing mpv internals, or serve as examples. An extensive user-edited list of 3rd party scripts is available here:
https://github.com/mpv-player/mpv/wiki/User-Scripts
(Anyone can add their own scripts to that list.)
