The sound patches have now been implemented in Armbian current and edge.
The community images for orangepizero3 are only updated once a week. So either wait for a new image or build one yourself from Armbian build on github.
Hello, this quick tutorial is to introduce an experimental Debian and Ubuntu APT repository to install ffmpeg compiled with v4l2request and v4l2drmprime patches developed by Linux kernel, LIbreELEC and Kodi folks to allow hardware video decoding on stateless decoders like those implemented in Rockchip and Allwinner SoCs for h.264, h.265, vp8 and vp9 codecs.
The repository introduces a new ffmpeg package that integrates and substitues the base ffmpeg package and its related packages.
Preconditions:
Mainline kernel 6.1 or more recent
armhf or arm64 architecture
Supported distributions:
Debian 12 - Bookworm
Debian 13 - Trixie (only arm64)
Ubuntu 22.04 - Jammy
Ubuntu 24.04 - Noble
Rockchip and Allwinner have already been tested, but this should work on other platforms with stateless decoders supported in kernel
APT REPOSITORY SETUP
To install the repository, just copy and paste the lines in a terminal:
$ sudo wget http://apt.undo.it:7242/apt.undo.it.asc -O /etc/apt/trusted.gpg.d/apt.undo.it.asc
$ . /etc/os-release && echo "deb http://apt.undo.it:7242 $VERSION_CODENAME main" | sudo tee /etc/apt/sources.list.d/apt.undo.it.list
$ echo -e "Package: *\nPin: release o=apt.undo.it\nPin-Priority: 600" | sudo tee /etc/apt/preferences.d/apt-undo-it
INSTALL FFMPEG AND MPV PACKAGES
$ sudo apt update
$ sudo apt install ffmpeg mpv
SETUP MPV CONFIG FILE
$ sudo mkdir -p /etc/mpv
$ echo -e "hwdec=drm\ndrm-drmprime-video-plane=primary\ndrm-draw-plane=overlay" | sudo tee /etc/mpv/mpv.conf
You can now play your videos using mpv and they should run with hardware decoding if supported, either in virtual terminals or in X11/Wayland windows!
Enjoy!
Notes:
your mileage may vary a lot: the more recent is the kernel version, the better is support (you may need edge kernel)
bug: when rendered in X11/Wayland window, video may show scattered tiles during frames
bug: Lima driver (Mali 400/450) shows a red/pink tint when video is played in X11/Wayland (see https://github.com/mpv-player/mpv/issues/12968) (workaround below: https://forum.armbian.com/topic/32449-repository-for-v4l2request-hardware-video-decoding-rockchip-allwinner/?do=findComment&comment=177968)
you may want to add --gpu-hwdec-interop=drmprime-overlay to the mpv command line if used in pure virtual terminal (no X, no Wayland) to use direct-to-overlay output
Panfrost driver should work flawlessy
10 bit HEVC are generally supported on all Rockchip devices (rk322x, rk3288, rk33x8, rk3399), but Allwinner H3 have no hardware support for that
Hi, I think these messages are not related to analog audio, at least on my custom board with t507 processor, analog audio works with this error.
You can simply disable them as it was in the linux kernel 6.1
The sound works for me if I turn it on in the mixer
It’s strange, but I have another problem - the sound does not work through HDMI and there is also a problem with reading EDID through the DDC interface. I would be grateful if you could tell me whether automatic detection of monitor or TV resolution via HDMI works for you.
