Unsolved How to enable 1080p in Moonlight on RPi4

[porst17]

If spent the afternoon setting up Sunshine (Linux PC) and Moonlight (Recalbox 9.1 on RPi4), but can't get Moonlight to accept 1080p streams. My findings:

• Streaming from Sunshine to Moonlight on a MacBook works flawlessly in 1080p, both in h.264 and h.265, so I could confirm that the encoder is working as expected on the Sunshine side.
• I modified the moonlight_*.conf files located in /recalbox/share/system/configs/moonlight/ such that the video settings becomewidth=1920, height=1080, fps=60, but it does not seems to have any effect.
• I manually ran the command that is issued from EmulationStation when MoonLight is launched, but I added the --resolution 1920x1080 --fps 60 switches. With these options, 1080p streaming works as expected. However, I have no idea how to permanently add these switches to the command (and I'd prefer adjusting the moonlight config files).
• Is this a bug or am I doing something wrong?

Any help is appreciated.

I finally managed to figure it out. The reason why the above config files don't have any effect is simple, but not obvious: There are two variants of the Moonlight front-end: moonlight-embedded and moonlight-qt. The files in /recalbox/share/system/configs/moonlight are for moonlight-embedded, but Recalbox uses moonlight-qt on RPi4. Therefore, another config file is used which is located at: /recalbox/share/system/.config/Moonlight\ Game\ Streaming\ Project/Moonlight.conf.

It was not clear to me how to modify the config to switch to 1080p. The file is normally managed through the Qt front-end and not directly edited. So I installed moonlight-qt onto another Linux box, applied the settings through the UI and checked the config file. There required settings are part of the [General] section:

[General]
width=1920
height=1080
fps=60

Porting the settings over to my RPi4 Recalbox finally made it stream my 1080p desktop in 1080p! Looks much better now!
