VA-API on Wayland

vainfo
Trying display: wayland
error: failed to resolve wl_drm_interface(): /usr/lib/libEGL_mesa.so.0: undefined symbol: wl_drm_interface
vainfo: VA-API version: 1.22 (libva 2.22.0)
vainfo: Driver version: Intel i965 driver for Intel(R) Ivybridge Desktop - 2.4.1

      VAProfileNone                   :    VAEntrypointVideoProc
      VAProfileJPEGBaseline           :    VAEntrypointVLD

As you can see here, It gives this error when I run vainfo. which seems to be a popular issue that only happens on wayland.
So, I was wondering, What's causing it, Will it be fixed, And is it Critical?

Yes, I'm asking if it's critical because it seems that everyone with this very same issue says that video acceleration does not work under wayland, Even though the numbers in the "Video" column of inte_gpu_top keeps changing whenever a video is playing.

And to my understanding, If the numbers fluctuate then video acceleration is "supposed" to be working. Clearing things up would be very appreciated.

I have an i3 3240 with integrated graphics (intel hd 2500) If that matters.

In a nutshell: this error can't be fixed but hardware acceleration works anyway

Re: VA-API on Wayland

Doesn't happen here.
Intel xe2 (Core Ultra 7 258V) and intel-media-driver 25.3.4-1 installed

$ vainfo 
Trying display: wayland
vainfo: VA-API version: 1.22 (libva 2.22.0)

Re: VA-API on Wayland

This only happens with legacy clients that can't use intel-media-driver
