kodi video acceleration under wayland not working

Hey

I observed, that I only have hardware acceleration in kodi when I use Xorg and not the default wayland session of gnome3. My stem looks the following:

gnome is version 3.28.2

I verified the issue by logging into gnome with wayland and playing a video in kodi. Upon pressing "o" I saw that "SW" video decoder is used.
When I log into gnome with Xorg and do the same, I see "HW" as a decoder.

I found this bug https://bugs.archlinux.org/task/56122 but I'm not sure if it takels the same problem since it is from last year.

In the Kodi forum they blamed the way mesa is compiled: https://forum.kodi.tv/showthread.php?tid=315178

Anybody observed this as well? Is it worth a bug report?

Re: kodi video acceleration under wayland not working

AFAIK, someone correct me if I'm wrong VAAPI and the like do only work on Xorg correctly currently. The Kodi forum entry is about general acceleration (which likely lead to the bug you link and which has subsequently been fixed)

Re: kodi video acceleration under wayland not working

Re: kodi video acceleration under wayland not working

TL;DR : Kodi can use video acceleration on wayland, but that's still experimental

The solution is to use native-Wayland Kodi

The kodi PKGBUILD has no references to wayland at all .

first post in https://forum.kodi.tv/showthread.php?pid=2728327 suggest you'd need to set
-DCORE_PLATFORM_NAME and  -DWAYLAND_RENDER_SYSTEM to build a native wayland version.
Further in that thread it's said you need mesa-git and kodi-git, there may be other requirements.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.
