Repository for v4l2request hardware video decoding (rockchip, allwinner)

[robertoj]

I have tried again with orange pi zero 3, debian trixie linux edge, xfce desktop.

 

This time, I tried without compositor. I ran this from SSH, as my user:

killall xfwm4 && xfwm4 --compositor=off &

I got:  (xfwm4:7880): Gtk-WARNING **: 10:45:56.629: cannot open display:

 

Then I tried "killall xfwm4 && xfwm4 --compositor=off &" and there were no errors. The orange transparent effect when moving windows is now a white line rectangle

 

Then, mpv played my 1080p mp4 with low framerate (slow motion, 75% of speed)... sometimes with 100% CPU and sometimes with 25% CPU

 

I noticed this in the log (both high and low CPU cases)

[vd] Unsupported hwdec: drm
[vd] Using software decoding.

 

With high CPU:

[cplayer] Set property: user-data/osc/margins={"b":0,"r":0,"t":0,"l":0} -> 1

 

With 25% CPU:

[cplayer] Set property: user-data/osc/margins={"l":0,"b":0,"r":0,"t":0} -> 1

 

Whole log (low CPU case):

(Mpv.conf at the bottom)

Ryzer, did you turn the compositor off? Are you using an armbian-downloaded OS, or self built? What kernel version?

DId you change anything in the linux menuconfig?

 

I am recompiling again, having checked again that the new linux patches are taken.... how could I check that my current Linux kernel has the new v4l2, cedrus functions?

Then I will try again with Bookworm
