Fallback to an existing output or the default output if a non default output is selected

[m2Giles]

Is there an existing issue for this?

• I have searched the existing issues

Is your issue described in the documentation?

• I have read the documentation

Is your issue present in the nightly release?

• This issue is present in the nightly release

Describe the Bug

Configure output to something other than the default output (using one instead of zero).

Start sunshine. Sunshine will core dump once getting to a valid encoder. Sunshine then fails to start.

Since the webserver also crashes you have to go to the configuration file to change output to a valid output.

A somewhat similar (though I'm guessing this is for a running stream) was listed on windows: LizardByte/Sunshine#939

Expected Behavior

Gracefully fallback to an existing output or the default output if a non default output is selected.

Additional Context

This behavior was seen on flatpak, AUR (regular and git), PKGBUILD, and pkg.tar.zst.

While this could certainly be considered a "bug", I've moved this to feature requests since this won't be a high priority and will just get lost in the noise under "issues".

For now, it's best to set your config to valid values.

[m2Giles]

Yeah, that's what I ended up doing to fix the issue. I think a note in the documentation that it must be a valid display would also be sufficient for now.

While it seems obvious now that I think about it, the fact that it was core-dumping surprised me.

I stumbled upon this by not updating my configuration after moving away from using a virtual display.

I just bumped into the same issue. I was trying this to chose the monitor I want to share.
So far I have had to manually turn off my second monitor 😆
