Forcing adapter name + forced advertising of HDR/10-bit profiles causes the stream to crash at startup.

Version: 7d0456e

Forcing the advertisement of HEVC/HDR or AV1/HDR in the Advanced tab in combination with forcing the Adapter name in the Audio/Video tab causes the streams to crash at startup.

Update:

In my case, I have 2 monitors attached to 2 different GPUs (one is on the iGPU and the other is on the dGPU)
The dGPU is the one I want to encode with.

The stream started working fine when disabling/disconnecting the monitor attached to the iGPU.
Since then, I have re-enabled the iGPU attached monitor and the stream still works fine, even after restarting Apollo.

The issue is definitely linked to some interaction between codec advertisement and adapter forcing, though, as, without the previous manipulation, it was consistently working/crashing by either unenforcing the advertisement, or removing the adapter name.

[ClassicOldSong]

Maybe reboot your computer after setting AdapterName also fixes the problem

GPU preferences sometimes get janky when switched live.

Also if you're not using headless mode, you should also set the monitor ID. It's a Sunshine leftover problem.

[ClassicOldSong]

Any updates?

[ProTechnomancy]

Also if you're not using headless mode, you should also set the monitor ID. It's a Sunshine leftover problem.

I do both, depending on whether I'm at my desk, hadn't heard/seen a toggle for headless mode or monitor ID, seems like I need to revisit the wiki. Thx
