autosave.lua

-- autosave.lua
--
-- 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.
local options = require 'mp.options'

local o = {
	save_period = 30
}

options.read_options(o)

local mp = require 'mp'

local function save()
	mp.command("write-watch-later-config")
end

local save_period_timer = mp.add_periodic_timer(o.save_period, save)

local function pause(name, paused)
	if paused then
		save_period_timer:stop()
	else
		save_period_timer:resume()
	end
end

mp.observe_property("pause", "bool", pause)

Unfortunately there's no way to delete watch-later data from user scripts as far as I know, only save it.

Anyone knows if this is by design? Seems odd if true to me.

Edit: The same behavior happens with keybinds in input.conf, like CTRL+Q write-watch-later-config ; show-text "Wrote watch-later data". So programatically invoking the write-watch-later-config function wont erase the data even when doing a simple quit during the same run. Odd indeed.

Is there a way to suppress the "Saving state" message that prints in the terminal?

@john-x:

local function save()
	mp.commandv("set", "msg-level", "cplayer=warn")
	mp.command("write-watch-later-config")
	mp.commandv("set", "msg-level", "cplayer=status")

still works?
I put the script in mpv/scripts but not seem to work

edit:
I think dont work in folders/playlist

It might be worth opening an issue to request a way to remove the watch-later data programmatically.

There is now delete-watch-later-config, you can use this version of the script which takes advantage of it:

@CyberShadow thank you!

Can you copy an autosave lua script because i can't

How to copy it from where should I start copying local options.
