How to overlay multiple images over background image?

[gavin2812]

Hello,

I have the script below that correctly allows me to overlay a logo onto an image (logo over the background image).

I have been trying to overlay multiple images over the background image using different ways but all result in an error one way or another (too many to list!).

I'd like to be able to specify the location (x/y) of the other images that I want to overlay, so for example, background image is the whole background, image1 should go at location x=n/y=n, then image2 should be placed at x=n/y=n, etc...

What would be the correct format?

Many thanks in advance.

background = single("/home/test/background.png")
logo = single("/home/test/logo.png")	

def logo_overlay(background, logo) =

  def mkfilter(graph) =
    background  = ffmpeg.filter.video.input(graph, background)
    logo = ffmpeg.filter.video.input(graph, logo)

    v = ffmpeg.filter.overlay(graph, background, logo,
      y="0",
      x="0") 

    ffmpeg.filter.video.output(graph, v)   
  end  
  ffmpeg.filter.create(mkfilter)
end

video = logo_overlay(background, logo)
s = mux_video(video=video, audio)
