Can this work with Desktop Duplication API on a VM? #124

Open philippemnoel opened 4 years ago

philippemnoel commented 4 years ago

I'm trying to use Desktop Duplication API to capture the screen of a VM, but since there is no monitor it doesn't work. This code works on a headless VM, can the .dll be used to create a virtual monitor with the VM that I can use desktop duplication API with?

I haven't yet added any desktop duplication on it. If the normal BitBlt works then it would... :|

Normal BitBlt works on a headless VM if you maintain the RDP session active, but not if you close it. Unfortunately BitBlt is not fast enough for what I need, so I'm trying to use Desktop duplication but would need some sort of VNC server running or something else to fake a display -- are you doing that in this code / any idea how to do that?
