-- This script automatically loads playlist entries before and after the
|
|
-- currently played file. 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=no
|
|
images=no
|
|
videos=yes
|
|
audio=yes
|

additional_image_exts=list,of,ext
