Visor

A game capture system, along with a social media platform dedicated to sharing videogame clips.

Building

VCPKG

  • ffmpeg[avresample,bzip2,core,ffmpeg,ffplay,ffprobe,ffserver,gpl,lzma,nonfree,opencl,openssl,version3,x264] (x86-windows, x64-windows)
  • x264 (x86-windows, x64-windows)
  • websocketpp (x86-windows, x64-windows)
  • protobuf (x86-windows, x64-windows)
  • boost-random (x86-windows, x64-windows)

About the project

Injection

Visor includes a custom DLL injector which will inject our library along with its dependencies into any valid graphics application.

In the future we would like to automate the process by periodically scanning the list of running processes and attempt to match the processes with a known list of valid game processes.

Overlay

Using our library, we're able to render an overlay over a graphics application to show the user notifications.
