Do something after screenshot

[barraIhsan]

Is it possible when screenshotting (either with s, S and <C-S> on a default bind) it will:

1. Save the file (default behaviour) and follow screenshot settings such as --screenshot-template
2. Copy the screenshot to the clipboard so we can directly paste it somewhere (e.g. Discord)
3. Apply custom extended attribute to the file (e.g. apply user.xdg.tags), or if it's simply not possible can we just run a command (like after-screenshot hook or smthing like that) so we can do setfattr using the cli

Sorry, have no time to try it. But maybe like this?
s screenshot video; run "/bin/zsh" "find ~/Screenshots -type f -mmin -60 | tail -n 1 | xclip"

[barraIhsan]

yes, but I'm afraid that it's only possible using lua, and I want to make it simple for me (as I never touched lua, well except nvim, and also mpv api)

yes, but I'm afraid that it's only possible using lua

It's way better to do it in lua, than running shell scripts from input.conf. Either way, there is some work to make the result of the command possible to be used in input.conf context #15921. Though looking at the discussion there, don't expect it to be available soon.

Yes, I would also think that is the case, but from what I see from other's implementation, such as clipshot.lua, the lua script just ran a shell command. So I thought to myself, why don't I just make it on shell script if I can't make it on pure lua then?

[kasper93]

the lua script just ran a shell command.
Do something

It depends what is the "something" you want to do. You seem to want to do screenshot to clipboard, it may be available negatively one day #15568

The 3 point that I mentioned from my original post.
Anyway yeah, clipboard and adding a custom tag (user.xdg.tags)

Thanks @Bellavene for letting me know that running shell script is possible and it made me look into the documentation
Ok, so my final approach would be
input.conf

# Original resolution w/ subtitles
s screenshot; run "/bin/sh" "-c" "~/.config/mpv/screenshot.sh ${screenshot-dir}"
# Original resolution w/o subtitles
S screenshot video; run "/bin/sh" "-c" "~/.config/mpv/screenshot.sh ${screenshot-dir}"
# Window w/ OSD and subtitles
Ctrl+s screenshot window; run "/bin/sh" "-c" "~/.config/mpv/screenshot.sh ${screenshot-dir}"

I use /bin/sh -c so that ~ can be expanded.

And inside that shell script

#!/bin/sh

# Getting the latest file in the mpv screenshot dir
FILE=$(ls -t $1 | head -n 1)
FULL=$1/$FILE

# Copy that file into clipboard
# On X11 and Wayland
if [ "$XDG_SESSION_TYPE" = "wayland" ]; then
  wl-copy < $FULL
else
  xclip -sel c -t image/png -i $FULL
fi

# Add to mpv user.xdg.tags
setfattr -n user.xdg.tags -v mpv $FULL

And now it's on lua

require("mp")

local function screenshot(flag)
	return function()
		-- take a screenshot based on the flags
		-- and store the path into a variable
		local filename = mp.command_native({ "screenshot", flag }).filename
		mp.osd_message("Screenshot (" .. flag .. ") taken")

		-- do the following action only if the platform is linux
		-- 1. copy to clipboard using wl-copy or xclip
		-- 2. add xattr to the file ("mpv" tag, where and when the
		-- screenshot was taken in the comment)
		if mp.get_property("platform") == "linux" then
			-- copy to clipboard
			if os.getenv("XDG_SESSION_TYPE") == "wayland" then
				os.execute("wl-copy < " .. filename)
			else
				os.execute("xclip -sel c -t image/png -i " .. filename)
			end

			-- xattr mpv tag
			os.execute("setfattr -n user.xdg.tags -v mpv " .. filename)
			-- xattr where and when comment
			local title = mp.get_property("media-title")
			local pos = mp.get_property("time-pos")
			os.execute(("setfattr -n user.xdg.comment -v '%s at %s' %s"):format(title, pos, filename))
		end
	end
end

-- set the same keybind as the default one
mp.add_key_binding("s", "subs", screenshot("subtitles"))
mp.add_key_binding("S", "video", screenshot("video"))
mp.add_key_binding("Ctrl+s", "window", screenshot("window"))
