I recently became aware of an awesome open-source program that allows streamers to capture a window showing what their current control inputs are. This is really useful for racing games and flight sims.
Sadly, the original project has been abandoned by the creator some years ago. This isn't too bad, except that the domains they link to that were hosting the binaries on have long since died and are now being squatted by scumbags. If you want this project all you are left with is figuring out how to build it yourself.
Since I was interested in using it grabbed a colleague from work and we figured out how to get it to build inside a docker container. I have forked the repo here and I have added the dockerfile and a build script. If you want to build it today all you need to do is grab the 2 files I added and run the script on a machine with docker installed.
The build process itself throws up some scary looking warnings - out of date insecure dependencies - but since I am not an Electron developer I can't say how bad this is. I have tried the output executables and can confirm that they work as expected. If anyone who is an Electron developer wants to submit pull requests I am happy to keep this project on life support.
I am not making the binaries available for general download as they are 500MB in total and I don't want that sort of traffic on this server, sorry. It's easy enough to build yourself now that I have added the build scripts.
For the more practical side of using it, Gaming on Linux has a short but good article on the program.
