It seems that Dav1d is developed by VLC together with ffmpeg. They say
it is software only
and does not uses any GPU acceleration:
https://www.videolan.org/projects/dav1d.html

It would be to try with Nvidia hardware to confirm.

It can use AVX2 in decoding, though. Do you have to enable this option
or is it by
default?

It seems that dav1d is not a very up-to-date project; if I wanted to
compare with
libaom I just need to disable "-enable-libdav1d" in configure?

Yes, it is a file 10-bit:

"pix yuv420p10le"; Color Space: bt2020nc; Color range: TV (mpeg).

Has anything changed between CinGG with ffmpeg6 and 7, since with
appimage I have no
problems
loading ("second error").

[PS:
Following the manual, I tried to start CinGG(ffmpeg7) with:
CIN_HW_DEV=vaapi ./cin
Now loading works without errors and playback works with a certain
percentage of GPU
acceleration (8-20%). If you try scrolling, however, there are
continuous freezes and
artifacts. But there are no messages and errors in the terminal.
