It does so by scanning the directory a file is-- located in when starting playback. It sorts the directory entries-- alphabetically, and adds entries before and after the current file to-- the internal playlist. (It stops if it would add an already existing-- playlist entry at the same position - this makes it "stable".)-- Add at most 5000 * 2 files when starting a file (before + after).
--[[To configure this script use file autoload.conf in directory script-opts (the "script-opts"directory must be in the mpv configuration directory, typically ~/.config/mpv/).
Option `ignore_patterns` is a comma-separated list of patterns (see lua.org/pil/20.2.html).Additionally to the standard lua patterns, you can also escape commas with `%`,for example, the option `bak%,x%,,another` will be resolved as patterns `bak,x,` and `another`.But it does not mean you need to escape all lua patterns twice,so the option `bak%%,%.mp4,` will be resolved as two patterns `bak%%` and `%.mp4`.
Example configuration would be:
disabled=noimages=novideos=yesaudio=yesadditional_image_exts=list,of,extadditional_video_exts=list,of,extadditional_audio_exts=list,of,extignore_hidden=yessame_type=yesdirectory_mode=recursiveignore_patterns=^~,^bak-,%.bak$
