Odroid hc4 video hardware acceleration

Hello, I have an odroid hc4 which I am mainly using as a home NAS. I chose Armbian + OMV (headless) and it works really well.

Now I tried using it as a media center at the same time with kodi. I tried both the "old" kodi version from the debian repos and also the flatpak version. For both it seems like the hardware acceleration isn't working. I can run youtube 1080p with vp9 quite fine, but neither 1080p with h264, nor anything 4k, at this resolutions it's stuttering a lot. Also the CPU-usage is always very high.

When i start flatpak-kodi it returns:

'this->recurse > 0' failed at ../src/pipewire/thread-loop.c:62 do_unlock()
libva info: VA-API version 1.22.0
libva error: vaGetDriverNames() failed with operation failed

When i start debian-kodi it returns:

[W][00397.628288] pw.conf      | [          conf.c:  939 try_load_conf()] can't load config client.conf: No such file or directory
[E][00397.628631] pw.conf      | [          conf.c:  963 pw_conf_load_conf_for_context()] can't load default config client.conf: No such file or directory
libva info: VA-API version 1.17.0
libva info: Trying to open /usr/lib/aarch64-linux-gnu/dri/meson_drv_video.so
libva info: va_openDriver() returns -1

For testing i installed coreelec and suddenly all youtube videos, even 4k ran perfectly fine with low cpu-usage.  I couldn't find any solution for armbian, any ideas? I would like to stick to armbian, I need a full linux environment. If nothing works, is it maybe possible to dualboot armbian and coreelec?

Don't know if this is relevant: flatpak-kodi uses OpenGL 3.1 Mesa 24.3.1 while coreelec uses OpenGL ES 3.2

Thanks for your help and sorry if i chose the wrong topic category
