[Efforts to develop firmware for H96 MAX V56 RK3566 8G/64G]

Could anyone advise the simple example on how to play media files using hardware decoding on VPU?

I use actual version of Armbian with Edge kernel

user@h96-tvbox-3566:~$ uname -a
Linux h96-tvbox-3566 6.18.0-rc7-edge-rockchip64 #1 SMP PREEMPT Sun Nov 23 22:53:16 UTC 2025 aarch64 aarch64 aarch64 GNU/Linux

and seems that rkvdec is available

user@h96-tvbox-3566:~$ v4l2-ctl --list-devices
rockchip,rk3328-vpu-dec (platform:fdea0000.video-codec):
        /dev/video2
        /dev/media1

rockchip,rk3568-vepu-enc (platform:fdee0000.video-codec):
        /dev/video3
        /dev/media2

rockchip-rga (platform:rga):
        /dev/video1

rkvdec (platform:rkvdec):
        /dev/video0
        /dev/media0

 

then I've installed MPV player from Armbian repository using apt command, but it seems that it doesn't support hardware decoding. I tried to use different hwdec options (rkvdec, rga, rkmpp, hantro....) but got "Unsupported hwdec" each time. 

 

user@h96-tvbox-3566:~$ mpv -hwdec=rkvdec --vo=gpu big_buck_bunny_1080p_h264.mov 
 (+) Video --vid=1 (*) (h264 1920x1080 24.000fps)
 (+) Audio --aid=1 --alang=eng (*) (aac 6ch 48000Hz)
