Add Picture-in-Picture button

[XCanG]

I have an suggestion to add this sort of button, there is really not much that probably need to be done:

1. Remember current position and size.
2. Resize it to small window in a bottom-right corner.
3. Apply always on top.
4. Optional: hide most of other UI

Clicking button again will restore previous state.

I think it would be really useful feature. I, myself sometimes watching steams in mpv and while I can do this manually with a bunch of hotkeys, this process always take some time and I couldn't revert it instantly as well. I wish to have this sort of convenient button.

We can't read or set window position or size. And this is more of a job for desktop environment imo. I'm personally using autohotkey to position window to a specific place:

+PrintScreen::
	if WinExist("ahk_exe mpv.exe") {
		WinGetPos,,,W,H
		WinMove,,, 2560-620, 40, 620, % 620 * (H/W)
	}
	return

And I have an old autotop script which enables on top only when media is playing, or is in fullscreen/maximized mode:

local options = {enabled = false}
require('mp.options').read_options(options, 'autotop')

function decide_on_top()
	local is_fullscreen = mp.get_property_native('fullscreen') == true
	local is_paused = mp.get_property_native('pause') == true
	mp.set_property_native('ontop', is_fullscreen or (options.enabled and not is_paused))
end

function set_enabled(value)
	options.enabled = value
	mp.commandv('script-message-to', 'uosc', 'set', 'autotop', options.enabled and 'yes' or 'no')
	decide_on_top()
end

mp.observe_property('pause', 'bool', decide_on_top)
mp.observe_property('fullscreen', 'bool', decide_on_top)

mp.add_key_binding(nil, 'toggle', function() set_enabled(not options.enabled) end)

-- uosc integration

mp.register_script_message('set', function(name, value)
	if name == 'autotop' then set_enabled(value == 'yes') end
end)

-- initialization

mp.add_timeout(0.5, function() set_enabled(options.enabled) end)

Which I add to controls bar with:

toggle:push_pin:autotop@autotop?Auto on top

I then have another autohotkey script which converts global PrintScreen to f and sends it to mpv player, which fullscreens the window. That causes the autotop script to also on-top it. Useful to temporarily fullscreen a video on the side if something interesting is going on without loosing focus of current app you're using.

Hm, I'm not that familiar with available functionality. It is sad then, that this is not a thing. If making ahk script, then need to add a little more stuff. Window need to remember position and set always on top. Anyway, this would be beyond original suggestion.

mpv doesn't use any OS's PIP api. I think the request should be firstly posted to mpv instead.

When I suggested it here I was not referring to anything related to that.
I know that there is T cycle ontop
But I didn't look if there are any windows resizing features. However I know that there some settings for mpv.conf, plus I know that there is also keybindings to shift video and resize, so I assumed that there is functionality already. I suspected it is simple 3 commands: enable always-on-top, move, resize. But from other post message, there isn't enough api and it even not possible, so I didn't know about that.
