Check mpv-zenity-open-files for a version which uses Gnome's zenity.

Thanks for this useful script.

Could you may be add on option to force the dialog on top of mpv player.

I use ontop option and the dialog opens below the player.

Edit: I added some code in the beginning and end of the function, and it behaves as expected.

Beginning:

    is_ontop = mp.get_property_bool("ontop")

    if (is_ontop == true) then
        mp.set_property_bool("ontop", false)
    end

End:

mp.set_property_bool("ontop", is_ontop)

Hello. I'm packaging this plugin for Gentoo, and I noticed that it does not have a license.
I think this is not what you intended, since it restricts the use to pretty much no one.
Could you please edit the script and add a license in the header?

Perhaps of interest: an inspired minimalist implementation that uses fdfind and fzf for file selection: from stack-overflow answer

I added the license, sort of.
Feel free to use the script in any way you wish.

how do I make it open specified directory when I press ctrl+s

    local focus = utils.subprocess({ args = {'xdotool', 'getwindowfocus'} })
    
    if mp.get_property("path") == nil then
		directory = ""
	else
		directory = utils.split_path(utils.join_path(mp.get_property("working-directory"), mp.get_property("path")))
	end
    
    local sub_select = utils.subprocess({
        args = {'kdialog', '--attach='..focus.stdout..'' , '--title=Select Subtitle', '--icon=mpv', '--geometry=750x450', '--getopenfilename', ''..directory..'' , 'Subtitle Files ('..sub_extensions..')'},
        cancellable = false,
    })
    
    if (sub_select.status ~= 0) then return end
    
    for filename in string.gmatch(sub_select.stdout, '[^\n]+') do
        mp.commandv('sub-add', filename, 'select')
    end
end

I changed the directory variable in add subtitle function but it opens still false path.

If you want to only load subtitles from a specific directory delete this if statement inside add_subtitle function

if mp.get_property("path") == nil then
        directory = ""
else
	directory = utils.split_path(utils.join_path(mp.get_property("working-directory"),mp.get_property("path")))
end

and replace it with the path you want
directory = "/the/path/to/your/subs"

appreciate you
