Perhaps nothing, as hardware decoding does seem to be working regardless.
output of vainfo in wayland session returns:
vainfo
Trying display: wayland
error: failed to resolve wl_drm_interface(): /usr/lib/libEGL_mesa.so.0: undefined symbol: wl_drm_interface
libva error: /usr/lib/dri/i965_drv_video.so init failed
vaInitialize failed with error code -1 (unknown libva error),exit
in an x11 session vainfo shows correctly.
vdpauinfo shows correctly under both wayland and x11.
I have followed the arch wiki guide, but remain puzzled…

I assume libva-intel-driver is installed?
installed is libva-intel-driver-hybrid

Please try with libva-intel-driver from repo instead 
.
Same result.

have you version lib32-libva-intel-driver installed ?
Seems that is talking about x11 session. My problem exists in wayland only. Thanks
