+-- autosave.lua
+-- based on https://gist.github.com/Hakkin/5489e511bd6c8068a0fc09304c9c5a82
+--
+-- Periodically saves "watch later" data during playback, rather than only saving on quit.
+-- This lets you easily recover your position in the case of an ungraceful shutdown of mpv (crash, power failure, etc.).
+--
+-- You can configure the save period by creating a "lua-settings" directory inside your mpv configuration directory.
+-- Inside the "lua-settings" directory, create a file named "autosave.conf".
+-- The save period can be set like so:
+--
+-- save_period=60
+--
+-- This will set the save period to once every 60 seconds of playback, time while paused is not counted towards the save period timer.
+-- The default save period is 30 seconds.
