Anyway to change frame resolution or rotate captured screen?

[LichLord91]

I was able to successfully use cmake on my Steam Deck to create my own package for sunshine so that I could use the wayland/kms session. However using kms/wayland the screen is captured vertically. The steam deck screen is naturally 800:1280 5:8 aspect ratio which valve rotates by 90 degrees to show a horizontal view to make it look 1280x800. I was curious if there's a way to rotate/set the custom frame capture resolution through sunshine.

game mode capture

desktop mode capture

P.S happy to build a custom branch/modification of code to test this if there's a special version we can make for steam deck

Probably should move this discussion here: https://discord.com/channels/804382334370578482/1019471681913372672

Since that thread was started by the creator of the patch you are referring to.

Any idea what I modify in the windows files to achieve this result?
Thanks.
