None

Describe the Bug

Use environment variables in global preparation command. For example, change the virtual display resolution in register. It will only move like %SUNSHINE_CLIENT_HEIGHT% into the register.

Expected Behavior

It can correctly parse the variables to value.

Additional Context

Maybe it can work past, but I'm not sure. I haven't use sunshine for a time, and these days I reuse this and update it.

I seems found this part of code? https://github.com/LizardByte/Sunshine/blob/master/src/process.cpp#L155-L177 So it's just works in the app execution? Can we change its area of influence to the whole Sunshine? Or just all writable commands.

You can submit a PR adjusting them to work with global prep commands.

I want, but I have no C++ programming experience :(

No need, can confirm it already works with global prep commands because all of my scripts rely on that and can read the environment variables just fine.

[ReenigneArcher]

In that case, probably need to prefix the commands with cmd /c

Did the latest release v0.23.1 had supported this? Or just newer pre-release had added this? If pre-release added, I will have a try. But if latest release had this feature, why the environment variables didn't parsed in my command of adding registry? I'm very confused.

upd: So it's just need to add cmd /c, I'm so stupid

Thank you so much
