couldn't enable hardware acceleration on wallpaper engine using mpv

[kito30]

Describe the bug

The cpu using 50% to 90% to render sence instead of using gpu to decode

System Information

• Kde: Plasma 6
• Qt: [6]
• OS: [Arch Linux]
• Installation Source: From AUR plasma6-wallpapers-wallpaper-engine-git

Additional context

Im using intel-media-drivers, hardware acceleration works on mpv but not on wallpaper engine plugin

[nickheyer]

Surprised you got this working on plasma 6. It totally broke kde/x11 for me.

Do you mean make this plugin work with your discrete graphics card ? I make some environment variable make my system use
NVIDIA discrete graphics card first , then all applications work on it , this plugin work too .

[kito30]

@zjypls I think that the hardware acceleration work with video types, but not for scence type.

This plugin even works on NVK + zink, so probably some setup problem, or bug in the proprietary driver, or relates to some specific scene?

[kito30]

I can confirm that it does not work with scence, only via video then the hardware acceleration start working. I've already install vulkan-intel and intel-media-drivers which are necessary driver which required by wallpaper engine plugin. It also mess up with my power management so I end up uninstalling it.

If you are saying Intel GPUs, on the same machine, using i7-10875H + Mesa 24.0.1, rendering the scene above uses ~2% CPU.

[kito30]

I am usimg i7 8550u and when render sence its always above 30% cpu usage. Can you name which driver are you using ?

[fxzjshm]

i915 (Linux 6.7) + iris (Mesa 24.0.1)

[kito30]

maybe due to kde 6 patch, or just my because of my scence
