Slow Video Problem

Hello all, I am using NetBSD 9 on my laptop, I installed firefox
and mpv and i noticed that video is slow.

In youtube I noticed it slow particularly when I am in fullscreen.

Mpv reported the following messages when trying to reproduce a video: https://bsd.to/XS4S

My laptop has two video cards but I think NetBSD is only using the integrated
video card. I provide my dmesg output here: https://bsd.to/Aof2

Also my /proc/cpuinfo is this one: processor: https://bsd.to/uzjK

Can somebody help me understand what may be the cause of this?
Or how can I fix this?

I didn't touch any of the Xorg config stuff.

Hope you can help me, was really excited to use NetBSD on my driver laptop.

Thanks

pin Actually i found out that libvdpau was not installed....
Anyway after installation, I retried with mpv and the situation is worse, now i have no video.

Mpv gives me the following error messages:
https://bsd.to/jMJp

Any idea? what should I do? It seems like it is not finding the .so, but I am sure I installed libvdpau.

What should I do?

pin Any other idea on how to solve this?

nia Ok here is the requested infos:

glxinfo: https://bsd.to/KbMm
cat Xorg.0.log: https://bsd.to/pmcV
ls -l /dev/dri output: https://bsd.to/yxDL
id: https://bsd.to/MBr3

Any idea on this?

nia The output of mpv can be found here: https://bsd.to/Dz6J

The issue is the same, the video is extremely slow.

Any other ideas on what could be the problem?
I am lost.

rvp Ok i am about to do this test, but in the meanwhile I wanted to share additional info when I tried
to download a youtube video with youtube-dl and tried to play with vlc.

VLC seems not able to work at all with the following errors:
https://bsd.to/WKOt

Are the issues related?
P.S.: I am about to try your suggestion now.

rvp I installed:

• gst-plugins1-vaapi-1.16.2nb1
• intel-vaapi-driver-2.4.0

Then i rebooted, and tried with mpv --vo=vaapi video.mp4, now the video works, but i still get the warning
from mpv that the VO is low quality and that vo=gpu should be the preferred option.

Anyway after installing those packages vlc does not show any warnings about drivers, but still i am not able to play videos.

nia Can you tell me how you verified if it was using GPU acceleration or not?
Thanks

nia Yes but I wanted to learn how to check if acceleration is enabled.
@nia also it seems i have the same issue with vlc, it just hangs the system.

At first it was complaning about missing driver "intel vaapi", then I installed it, and it still crashes.

Any idea? Also how could i fix mpv to make it work?
Should i recompile it with opengl support?
Do you think that may help?

rvp Yes thanks a lot for the info, I deep dived into video playing to really understand where my issue was.

It actually seems that my CPU is too old and requires playing videos using hardware decoding and vaapi as backend.
In this way the performances are acceptable anyway I cannot use --vo=gpu (after i compiled mpv with opengl support, since in the binaries mpv is compiled without opengl support) since it has massive frame drops and sometimes the video hangs.
Anyway thanks for the suggestions.
