-- This script automatically loads playlist entries before and after the -- 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/).
