BGE: Fill-in DeckLink object.
Implement the DeckLink object to output on DeckLink card. It takes a
source like the Texture object and gets the image the same way.
API:
dl = bge.texture.DeckLink(0, "HD1080p24") # card nb, mode
dl.source = bge.texture.ImageViewport()
dl.source.whole = True
dl.refresh(True)
Known issue: using ImageViewport as source will not set the alpha channel
right. This is because the framebuffer by default will not have an alpha
channel. This can be solved either by inserting a 'green' filter that will
convert the background color to alpha, or enable the alpha channel on the
framebuffer (require change in Ghost).
