I havnt got horizontal keystone on my projector and want to project on a surface that is not right in front of the projector.
My idea is to go through a processing sketch running on an raspberry pi. Basically by outputting a corner pinned version of the desktop to my projector connected through hdmi. Using the Keystone library.,
Just need to be able to grab the screen in some way.
Are there any library for capturing the screen and stream it?
