Steam game launcher with exit detection/handeling

I made a simple program that launches a Steam Game and monitor its main process so we can control its lifetime. This means, if the game closes itself, the stream will end too, or if you end the stream yourself, the game will end too.

This is a proof-of-concept for now, and it's just barely on Beta. And a big caviat is that you need both the Game ID (as the same as the current way for steam games) and the Game executable path, which it's not always the first .exe that you find on the game's directory. You can see the README.md for a real life example.

If you want to test it, you can check my Repository and its Release page, it works for both Windows and Linux (I don't have a Mac so I cannot build it nor test it for now).

If you find any bug or game that doesn't work correctly, please add an Issue and I'll try to investigate

Would you be interested in integrating this directly into Sunshine?

[JPZV]

It would be nice, as it's written in C++. Maybe it could be integrated as a Script/Tool/Submodule to avoid any issue within the core of Sunshine.

The downside is that knowing the real game executable is a must, as there is no way to do it programmatically (in 2019 it was kind of possible, but nowadays Steam hides the command line used for the game, and even with that it may just use the launcher)

Is it contained in the vdf file?

It did, but nowadays all games points to steam.exe no matter what (at least on my machine running Windows 11). I have three libraries, and all of their vdf points to steam.exe
