Script error?

[Lergen]

Hello. I made a slight modification to Dutchman's BSOD script to play a video rather than display an image, but I'm receiving an error on line 5: "attempt to call global 'playVideo' (a nil value). Can anyone offer some advice as to what's wrong here? I'd greatly appreciate it.

local bsodTimer

function renderBSOD()
    local x, y = guiGetScreenSize()
    playVideo (0, 0, x, y, "bs2.mp4", 90600, false, false) -- bs.png for win7/XP, bs2.png for Win10/modern BSOD screen. change at will
end

function performPrank(thePlayer)
	if (thePlayer == getLocalPlayer()) then
		if (isTimer(bsodTimer)) then
			killTimer(bsodTimer)
		end

		for i = 1, 100 do
			setWorldSoundEnabled(i, false)
		end
		setAmbientSoundEnabled("general", false)
		setAmbientSoundEnabled("gunfire", false)
		setInteriorSoundsEnabled(false)
		showChat(false)
		setPlayerHudComponentVisible("all", false)
		setSoundVolume(sound, 0.5)

		removeEventHandler("onClientRender", getRootElement(), renderBSOD)
		addEventHandler("onClientRender", getRootElement(), renderBSOD)

		bsodTimer = setTimer(
			function()
				removeEventHandler("onClientRender", getRootElement(), renderBSOD)
				showChat(true)
				setPlayerHudComponentVisible("all", true)
				setAmbientSoundEnabled("general", true)
				setAmbientSoundEnabled("gunfire", true)
				setInteriorSoundsEnabled(true)
				resetWorldSounds()
				end,420000,1)
		end
end
addEvent("showBSODToPlayer", true)
addEventHandler("showBSODToPlayer", getRootElement(), performPrank)

'playVideo' is not a built in function. Its a useful function that can be found on wiki but it has to be defined first. Copy and paste this above renderBSOD,

function playVideo (posX, posY, width, height, url, duration, canClose, postGUI)
	if not posX or not posY or not width or not height or not url then
		return false
	end
	local webBrowser = false
	closeButton = guiCreateButton (0.97, 0, 0.03, 0.03, "X", true)
	guiSetAlpha (closeButton, 0.5)
	guiSetVisible (closeButton, false)
	if not isElement (webBrowser) then
		webBrowser = createBrowser (width, height, false, false)
		function createVideoPlayer ()
			function webBrowserRender ()
				dxDrawImage (posX, posY, width, height, webBrowser, 0, 0, 0, tocolor(255,255,255,255), postGUI)
			end
			loadBrowserURL (webBrowser, url)
			
			setTimer (function()
				addEventHandler ("onClientRender", getRootElement(), webBrowserRender)
				showChat (false)
				if canClose then
					guiSetVisible (closeButton, true)
					showCursor (true)
				end
			end, 500, 1)
			setElementFrozen (localPlayer, true)
			if duration then
				videoTimer = setTimer (function()
					removeEventHandler ("onClientRender", getRootElement(), webBrowserRender)
					setElementFrozen (localPlayer, false)
					guiSetVisible (closeButton, false)
					showCursor (false)
					showChat (true)
					destroyElement (webBrowser)
				end, duration, 1)
			end
			
			addEventHandler ("onClientGUIClick", closeButton, function (button, state)
				if button == "left" then
					if isTimer (videoTimer) then
						killTimer (videoTimer)
						videoTimer = nil
						removeEventHandler ("onClientRender", getRootElement(), webBrowserRender)
						setElementFrozen (localPlayer, false)
						guiSetVisible (closeButton, false)
						showCursor (false)
						showChat (true)
						destroyElement (webBrowser)
					end
				end
			end, false)
		end
		setTimer (createVideoPlayer, 500, 1)
	end
end

Thanks for the tip. So after trying that code and starting the script, I get barraged with error messages when I start the video:

"bad argument at 'dxDrawimage' [expected material at argument 5, got nil]" and "bad argument at 'loadbrowserURL' [expected browser at argument 1, got nil]"

Thinking the problem was with it being that I was using a video file rather than a video URL, I tried the YouTube example on the wiki

function renderBSOD()
    local x, y = guiGetScreenSize()
    playVideo (0, 0, x, y, "https://www.youtube.com/embed/rRjY8SOZ9Uo?autoplay=1&showinfo=0&rel=0&controls=0&disablekb=1", 90600, false, false) -- bs.png for win7/XP, bs2.png for Win10/modern BSOD screen. change at will
end

However doing it this way causes the screen to go white and crashes MTA.
