Please test the extension:

-- "force aspect ratio.lua" -- VLC Extension

aspect_ratio = "16:9"  -- "" for default AR

function descriptor()
	return {
		title = "Force Aspect Ratio",
		version = "1.0",
		capabilities = {"meta-listener"}
	}
end

function activate()
	Set_AR(aspect_ratio)
end
function deactivate()
	Set_AR("")
end

function meta_changed()
	Set_AR(aspect_ratio)
end

function Set_AR(ar)
	local vout=vlc.object.vout()
	if vout then
		vlc.var.set(vout,"aspect-ratio",ar)
	end
end

It takes "Integer:Integer" values, so "221:100" instead of "2.21:1".
Added simple dialog box with all available predefined aspect ratios:

Code: Select all

-- "force aspect ratio.lua" -- VLC Extension
--[[ Changelog:
(1.1)
* Simple dialog box with drop-down list of aspect ratios and APPLY button;
* OSD message;
(1.0)
* Initial release;
--]]

aspect_ratio = ""  -- "Integer:Integer"; "" for default AR
aspect_ratios = {"","1:1","5:4","4:3","16:10","16:9","221:100","235:100","239:100"}

function descriptor()
	return {
		title = "Force Aspect Ratio",
		version = "1.1",
		capabilities = {"meta-listener"}
	}
end

function activate()
	Create_dialog()
	Set_AR(aspect_ratio)
end
function deactivate()
	Set_AR("")
end

function meta_changed()
	Set_AR(aspect_ratio)
end

function Set_AR(ar)
	local vout=vlc.object.vout()
	if vout then
		vlc.var.set(vout,"aspect-ratio",ar)
		if not channel1 then channel1 = vlc.osd.channel_register() end
		vlc.osd.message(ar,channel1)
	end
end

--- Dialog box ---

function close()
	vlc.deactivate()
end

function Create_dialog()
	w = vlc.dialog(descriptor().title .. " (" .. descriptor().version ..")")
	w1 = w:add_dropdown(1, 1)
	for i,v in ipairs(aspect_ratios) do
		w1:add_value(v, i)
	end
	w2 = w:add_button("APPLY", click_APPLY, 2, 1)
end

function click_APPLY()
	aspect_ratio = w1:get_text()
	Set_AR(aspect_ratio)
end

Tip: use keyboard down/up arrow keys and enter in the dialog box
