RetroPie Screen Mirroring / Streaming / Casting

[HorseWithForce]

hey there,

I know the thread is a little old but I'm trying to install uv4l for 5 hours now and I ran into diffrent problems..... first I sadly cant install RetroPie on x64 Raspi OS with Bullseye, next was that it seems that uv4l wont run on bullseye regardless x86 nor x64 bit OS....
now i took a fresh retropie image to test it with buster and followed some instructions here and there https://www.linux-projects.org/uv4l/tutorials/play-retropie-in-browser/
but I'm always leading to a point where my browsers gives me an error "invalid video device" or with another config I get "Web socket error 1006"
I guess I used the wrong video output in the config, but I cant find the right one....

Also the Retro Pi emulation wont start cause it tells me no display connected...
I only use ssh to connect to my pi and i got no Display or hdmi connected to the pi
Should I virtually add a display in the configs or is there any other solution here?

I hope you can help me out!

That's probably the reason why it's not working - there's no video device initialized. You didn't mention which Pi model are you using, but as a general solution, configure a video mode in /boot/config.txt and set hdmi_force_hotplug=1 as-well so that display detection is skipped.

As for using the solution on the RaspiOS Bullseye, it will not work due to the fact that the MMAL/DispmanX API is no longer supported with the new KMS ARM driver.

Just out of curiosity, why are you trying to use this solution, if you don't have a display attached to the Pi ? Wouldn't it be easier to install the emulators on your PC/Phone to play ?
