Hi there!
I used to run RaspberryOS "buster" with a long working Hyperion (years old, I don't remember the version...). I now upgraded to Raspberry OS "bullseye", and installed Hyperion as per the documentation. I successfully used the webinterface to configure everything according to a backup of my old working hyperion.config.json.
Everything seems fine, I can use the remote to show some swirly effects, but I'm unable to use the live video to grab the colours of the screen.
I notice that as capturing hardware, there's only "Framebuffer" while my old hyperion installation used "Dispmanx". Is that my problem?
Is there a way to get the "Dispmanx" device back?
Thanks a lot!
