fast playback on resumed playback

[markifi]

it works amazingly well, the only very slight thing i found is if mpv.conf has
save-position-on-quit
and you quit while it's sped up, open the file later to resume, playback speed defaults to the multiplied speed.

also the default threshold setting was low to me and i increased it to -26 dB, but i guess that's personal preference.

Yeah, I'm aware of the problem, but I don't know if there's a way to prevent this. For now you'll have to reset the speed manually after resuming from saved position.

Alternatively you may prefer removing speed from watch-later-options, so it's not saved at all, by adding this to mpv.conf:

watch-later-options-remove=speed

[idMysteries]

local watch_later_list = mp.get_property("watch-later-options", {})
local watch_later_speed = mp.get_property_bool("options/save-position-on-quit") and watch_later_list:find("speed")

local function toggle(flag)
    local arg
    if flag == "no-osd" then
        arg = "no-osd"
    end
    if is_enabled then
        disable(arg)
    else
        enable(arg)
    end

    if watch_later_speed then
        mp.commandv("change-list", "watch-later-options", is_enabled and "remove" or "append", "speed")
    end
end

Something like that? The speed will not be saved if the script is enabled. It's not a perfect solution, but I did it for myself.
