Sunshine is unable to force a Specific Encoder

[tristan-k]

Describe the Bug

Forcing Sunshine to use a specific encoder (here nVidia NVENC) isn't working since it is not recognized. The Nvidia card is not used for display out because I'll have to use the APU (Ryzen 7 5700G) in order to get AMD FreeSync support for my Monitor. How can I use the APU as display out device and force nVidia NVENC?

Expected Behavior

The specific encoder (here nVidia NVENC) should be forced regardless of which device (here Ryzen 7 5700G APU) is used for display out.

On Windows, you can only use the gpu that is rendering the monitor you select. See here: https://sunshinestream.readthedocs.io/en/latest/about/advanced_usage.html#adapter-name
