WindowCast for Libretro (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 (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.
Here’s an example of the core in action, capturing Dead Cells (image courtesy of HyperspaceMadness).
I plan to eventually have this core downloadable via the online updater. Until such time, you can download it from the following links;
Please read the included README file carefully, and expect some bugs/crashes to occur.
Source for the core is located at GitLab.
