It's here, 64-bit version. I don't use OBS anymore. I don't even play games that much let alone record them. So this is it. If this breaks, please fork the github repo and release a fixed version (sorry).
Special thanks to RiDDiCK51PB for motivating me to try compiling it lol. After a few struggles, it compiled even if OBS studio itself failed to compile in that project.
