For the second issue, you need to scale the video before displaying it,
otherwise you will hit the limits of the real X11 server.

For the first issue, this is not entirely surprising. Your task seem highly
unusual, and I think you are already lucky that existing tools can come near
realizing it with "just" performances issues. I am sorry I can not help you
