mpv script

autosave.lua

-- autosave.lua
--
-- Instead of saving only on quit, 'watch later' data is saved periodically during playback and when a file is unloaded.
-- 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 editing the follow line.
--
-- local 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 60 seconds.
-- If you want to disable this script, set the value of save_period to 0.
