mpv regression

23 May 2024, 13:17:26

Preface:
1. Same hardware/same computer with intel only
2. Two distros:
a) Artix (fully configured)
b) Devuan (fully configured, booted with refracta ISO, ilwlmicrocode included etc)

both set to use the same mpv config:
hwdec=vaapi
vo=gup-next

File 50 fps AV1 video:

Artix is using 2x CPU compared with Devuan on the same file.

$ pacman -Qs intel:
intel-media-driver 24.2.3-1
intel-gmmlib 22.3.19-1
libva-intel-driver 2.4.1-2
vulkan-intel 1:24.0.6-2
xf86-video-intel 1:2.99.917+923+gb74b67f0-2.2 (xorg-drivers)

$ pacman -Qs vaapi
gstreamer-vaapi 1.24.3-1
intel-media-driver 24.2.3-1
libvdpau-va-gl 0.4.2-3

Its 40% on Artix vs 20% on Devuan.
Any clue? So same laptop on Artix is getting hot and loud. On my Devuan snapshot its cold and quiet.

What are the versions of mesa, kernel and firmware? What are the differences on /boot/config-$(uname -r)?

Also, what's the log of mpv when you using it to open the file in command line?
