Hyperion.NG, internal Frame grabber does not work with Kodi

I followed the steps above with OSMC on Raspberry Pi 3b, without success. Can't get helerion to work with movies. Anyone got it working?

Fix FKMS HDMI Audio

Thanks for providing the instructions! I was able to make Hyperion.ng work with FKMS on Kodi 21 on arch-linux on RPi3 (I was fed up with Debian not offering a recent Kodi version), by downloading /opt/vc from raspberry-firmware/oldstable and then re-compiling the hyperion.ng-git AUR. hyperion-dispmanx will fail with a useless error message and you won't get the "DispmanX" drop-down option if /opt/vc/lib/libbcm_host.so doesn't exist at both compile- and runtime.

But similar to the RPi4 reports above, HDMI-CEC doesn't work. I tried booting the RPi3 with the already TV turned on and set to the right HDMI input, but CEC is not detected, and there is no /dev/cec0. Any ideas on how to enable CEC with FKMS on RPi3?

So I was really desperate. I tried the hyperion.ng DRM PR from 2022, and after struggling for half a day to compile it on the RPi3 (fighting the "gold" linker, Qt5/Qt6 issues, stray quotation marks, and some more), it finally started, only to show me this:

It goes on and on and on for a while, then runs out of file descriptors and dies. I'm really not sure what I can do from here.

Apparently, I can pick any two out of:

- streaming services (requires a recent Kodi)

- Hyperion (doesn't work on recent Kodi except with the FKMS hack that's not officially supported nor very efficient

- HDMI-CEC (doesn't work with FKMS)
