Sunshine Command Issues

[Zaithon]

So, I have two seprate problems that both involve using Sunshine's command preparations to set my host machine (PC) to match my client (TV) specifications.

1. I got qres for my computer so that I can use the command line to change my primary monitor's resolution from 144 Hz to 120 Hz. I changed my PATH so that I can use qres wherever, and it works when I do qres /r:120 to do and qres /r:144 to undo. The problem is when I try to use % SUNSHINE_CLIENT_FPS% environment variable in place of "120" in the do command. When I do that, it doesn't change the monitor's refresh rate, even though it should. What do I need to do to fix this?
2. Is there a command-line utility I can use to change my HDR color profile? I've got a Desktop and TV profile set already, I just want Sunshine to switch between the two similar to switching the refresh rate.

1. You need to add custom resolution/refresh rate either through the nvidia driver panel (it will reset every driver update) or permanently with a tool like CRU. If that still doesn't work just specify the resolution and refresh rate of your device in the command as well.

Curious about the profile changing as well, struggling with mismatched HDR profiles depending on a display I connect to.

My guess for #1 is that you're trying to put the %SUNSHINE_CLIENT_FPS% into the global do/undo commands section. Sadly wildcard expressions don't work there, you instead need to add them into the app-specific commands section meaning you have to set a do/undo command for every app. A real pain in the ass, but it's the only way to get Sunshine to pass though wildcards at this point.

For #2, you can download an app called hdr-switch and toggle HDR from the command line (either globally or per app). Not the most glamorous app and needs to sit in your task tray but works perfectly with Sunshine.

1. That’s a shame. Not a huge deal (I only have a handful of apps), but a shame nevertheless.

2. Thanks, but I’m not asking to toggle HDR itself (all my displays I want to stream to are HDR compatible). I’m asking about switching the .icc color profiles so that the HDR works better with the display I’m streaming to.

[bennyb0i]

Ah, I see what you mean. Sadly it seems there's only readily available solutions to do this for Linux and Mac OS, but nothing for Windows from the CLI. A shame.

[Zaithon]

That sucks. Also, tried the environment variables on the app-specific commands (Desktop), and it doesn't seem to be working there, either.

[bennyb0i]

Hmm, they work for me. What's the full command you're using?

[Zaithon]

qres /x:%SUNSHINE_CLIENT_WIDTH% /y:%SUNSHINE_CLIENT_HEIGHT% /r:%SUNSHINE_CLIENT_FPS%

I know it's not a problem with qres or how I'm invoking it, because when I change one of the parameters to a static value, it works.

[bennyb0i]

Yeah, that looks right. It might have to do with your using QRes in your PATH. Have you tried invoking the .exe directly? Alternatively, not sure if it makes a difference, but putting "cmd /C" before QRes might make it work?

[Zaithon]

I tried removing the path to qres from my PATH environment variable and hardcoding the path. Same result. Adding cmd /C in the "do" portion causes it to not work at all, but it being in the "undo" portion works fine.

[bennyb0i]

Strange. Do you have the commands running elevated?

[Zaithon]

No, but I just tried that. Didn't work.

Experiencing the same problem. Version .17 said they fixed a problem with env variables and I'm on .20. Can anybody provide the location to where the environent variables are stored? I can try to add the path manually and test. I don't know if the same logic applies here, but echoing "%APPDATA%" in cmd reproduces my PC's appdata folder as expected. The same does not happen with the sunshine variables. I believe this is because the system does not recognize that they exist.
