WindowCast for Libretro/libretro-wincapture (formerly WGC Window Capture) Libretro core to capture the contents of another window for video processing. This is useful, for say, capturing the output of a standalone emulator emulators that doesn't have advanced pp shader implementation (like [[xemu]], [[Dolphin standalone]], [[RPCS3 ]] or [[PCSX2 nightlies]]) or a PC game running in a window and then processing it with RetroArch's shader stack. This core uses software blit, and should support running with any RetroArch video driver (vulkan, d3d11, gl, etc). However, the method used for window capture is Windows 10/11 specific and requires a Direct3D 10/11 capable GPU. Audio or input is not handled, and it is expected that the game will be running in the background.
