Ok, I filed a bug here:

Hopefully they will understand.

Actually, I tried to run the following pipeline with v4l2h264dec in Wayland,
but with Gstreamer 1.14:
 gst-launch-1.0 -e filesrc location=/home/pi/jellyfish-15-mbps-hd-h264.mkv !
matroskademux ! h264parse ! v4l2h264dec capture-io-mode=dmabuf ! waylandsink

It is much faster than anything else in X11 (I was not able to fix
glimagesink in 1.16), but I am facing a lot of following warnings:
0:00:18.246613271   857 0x74213550 WARN             waylandsink
137:gst_video_format_to_wl_dmabuf_format: wayland dmabuf video format not

Would you be please so kind and give me a hint how to remove this warning
and take advantage of dma fully? I guess the dma is not used in this case as
it consumes a lot of CPU power.
