That will take some time to set the whole setup; unfortunately it is not easy task to bring up a system which could be used easily to rebuild the packages, but will do in the future. Can't say when though.

Hi @jock , I would like to request a Noble build as well. If hardware is an issue, I can help compile this (remotely).

Thanks!

jock · September 19

No hardware issue, the problem is rather finding the material time to do the task!

Hello all,

I tried the apt repo install instructions in the first post... but it seems that my armbian bookworm is still installing its own .deb package and not the one from the apt.undo.it repo

Is there an obvious step that I am missing?

What version of mpv should I have if I installed successfully?

Thank you in advance!!

(my target is orange pi zero 3)

P.S. I see that the debian repo (through my web browser) does not provide mpv.deb, but Ubuntu Jammy does... does this mean that the armbian-bookworm mpv.deb does not need the patches?

I also see that the available debs are 11 months old... perhaps if you could point to some instructions that work, we could do it ourselves and share the outcome.

Exacty, mpv in debian bookworm already has full support for drm-prime, so there is no need for a patched version of that

the instructions that work are there, in the meantime it can be that mpv changed some default, actually I didn't check recently

Hi, I tried this with armbian bookworm and orange pi zero 3 worked flawlessly with h264 hwdec.

I haven't been able to get it working, I also have the Orange Pi Zero 3 using the Debian 12 (Bookworm) [Build Date: Oct 14, 2024] image with the Minimal/IOT option.

I tried using mpv with the instructions at the beginning of the post on the Gnome and XFCE desktops, but both have the same negative result (sometimes the screen is black or shows a frame of the video, it can never be put into play and I can move through the time scroll to see other frames, but it is unusable).

The worst of all is that I do get the message "Using hardware decoding (drm)".

The only configurations I do after installing the image are:

sudo apt update && sudo apt upgrade -y

sudo apt-get install armbian-config mesa-utils chromium

# Install a Desktop
sudo armbian-config

# After rebooting and entering the desktop
sudo wget http://apt.undo.it:7241/apt.undo.it.asc -O /etc/apt/trusted.gpg.d/apt.undo.it.asc
echo "deb http://apt.undo.it:7241/debian bookworm main" | sudo tee /etc/apt/sources.list.d/apt.undo.it.list
sudo apt update
sudo apt install ffmpeg-v4l2request mpv
sudo mkdir -p /etc/mpv
echo -e "hwdec=drm\ndrm-drmprime-video-plane=primary\ndrm-draw-plane=overlay" | sudo tee /etc/mpv/mpv.conf

mpv video.mp4

This is the output on the XFCE desktop (but with the same negative result):

hiperdoo@orangepizero3:~/Downloads$ mpv --ao=pulse video.mp4
 (+) Video --vid=1 (*) (h264 1920x1080 60.000fps)

AV: 00:00:00 / 00:00:45 (1%) A-V:  0.006 Dropped: 7

I would be very grateful if someone could enlighten me on what other steps are required.

The last reported success was with Debian Bookworm, in a comment from July 23... can you repeat the experiment with an OS image from before that date?

(I don't have access to my orange pi zero 3 for a few days)

robertoj · November 4

I confirm that ffmpeg-v4l2request works for opiz3, with OS image Armbian_community_24.8.0-trunk.6_Orangepizero3_bookworm_current_6.6.31_minimal.img.xz

I started with the freshly booted OS image, added my DTS for ili9341 SPI LCD (see other thread in community-allwinner), rebooted, and followed all the steps in the original post.

I can only think of using apt to install an older mpv.deb (+dependencies), if starting from the newest Armbian OS...

Or forcing apt to never upgrade the mpv.deb and related deb dependencies, if I start with the older Armbian OS

As a temporary measure, only needed while ffpmeg gets the patches officially, and the Debian servers include that new version too, right?

Reference: https://unix.stackexchange.com/questions/242014/how-to-install-the-previous-version-of-a-deb-package-and-pin-it

Another thing to try is to compile an Armbian image (latest), with bleeding edge linux kernel, as I see success for other people in Linux 6.7

https://forum.armbian.com/topic/29794-how-to-install-armbian-in-h618/?do=findComment&comment=204697

Jock, if I want to build my own ffmpeg with v4l2-request, is this a good recommendation?

"You also need to build with --enable-v4l2-request --enable-libudev"

Thank you very much for your reply, but I can't find the old images of the Orange Pi Zero 3 anywhere. I found this archive link, but it doesn't have the OPi Zero 3, do you know where I can get the version of the image you mentioned?

robertoj · November 5

Fortunately, I was able to upload this file:

Armbian_community_24.8.0-trunk.6_Orangepizero3_bookworm_current_6.6.31_minimal.img.xz

https://drive.google.com/file/d/1nlvUPLOdIz706EWWv4c2BzPQxkzilZHG/view?usp=drive_link

If anyone has a similar file for the orange pi zero 2w, please share it too

I found that mpv.deb remains the same version from armbian 24.8 to 24.11 (from may to october 2024)... and the only thing that got upgraded is linux 6.6.31 to 6.6.54

Freezing the kernel in 6.6.31 could be a good move too

I also just finished compiling armbian with the latest kernel... I will try this next time I can.

I just had the chance to test an old Allwinner H3 (OrangePi One) with kernel 6.6.44 and can confirm that mpv fails to work correctly with hardware decoding, both via terminal and also in weston, both on kernel 6.6.44 and 6.10.8.

On rockchip64 instead it works pretty well in both terminal and weston on kernel 6.6.57.

I guess something broke in the kernel for allwinner platforms 😕

robertoj · November 6

I was successful with banana pi m2 zero and orange pi zero (same H3 chip), without your ffmpeg-v4l2request... just with official armbian packages.

jock · November 6

@robertoj well a 240p video is easy enough even for H3 without hardware decoding. The repository is intended for hardware decoding, and my tests were done with 720p30 h.264 and 1080p30 h.265 videos

robertoj · November 7

I will test again with my banana pi m2 zero (my only H3 SBC with HDMI)...

I am currently trying to build ffmpeg, but there's always a compilation error somewhere 🤣

robertoj · Friday at 05:35 AM

You are right jock

I tried my bananapi m2 zero, playing a 240p H264 mp4 with the HDMI output.

With mpv, the rendering is scaled full screen, at 3 fps and the cpu is 100%

With mplayer, the 240p shows as 240p, 24fps (1/4 the height of my LCD) and the cpu is 25%

with mplayer, a 360p video plays also, with 35% cpu

720p and 1080p videos are played very choppy with mpv and mplayer

It turns out i was never using hardware acceleration in my H3 boards

Next I will try with the orange pi zero 3... with kernel 6.6.31, where I could play in my 240p LCD, but in my HDMI LCD this time

...I can play 1080p video smoothly in the tty, but the cpu is at 100% in 1 core

I finished compiling ffmpeg-v4l2request from https://github.com/Kwiboo/FFmpeg in my orangepi zero 3, under 6.10.9, but still could not play to my 240p LCD

[can someone tell me how to activate HDMI in the orange pi zero 3, in an arbian OS which I built myself?]

jock · Friday at 02:56 PM

@robertoj I may guess there are some missing pieces in the armbian kernel for allwinner: for rockchip, there are some patches borrowed from libreelec to make it work correctly with all formats. I don't know what is the status for allwinner and if there are similar patches and fixes that are not include right now, you won't be able to get anything.

ffmpeg with v4l2request patches applied should work with any device which has a working v4l2request compliant drivers in the kernel, plus it also requires a properly working presentation framework for the DRM/DRMPrime and EGL parts, so there are several players involved: ffmpeg has to talk via v4l2-request to the kernel, the hardware decoding happens in the V4L2 drivers, but the presentation on screen happens within the kernel (DRM) and/or Mesa (EGL/OpenGL), bridged by DRMPRIME buffer sharing.

I guess Mesa is pretty ok, since both Lima and Panfrost have the necessary bits in place to present things on screen, yet the Cedrus hardware decoder driver has to properly support hardware decoding and buffer sharing via drmprime with the GPU driver. I made some simplifications here and omitted details, but as you see it is already a fairly complex communication setup, of which ffmpeg is just the "user" of all those other services.

robertoj · Friday at 07:03 PM

Nick A has some new linux patches that are related to ffmpeg:

The kernel fix in NickA’s Armbian, allows ffmpeg-v4l2 play 1080p with hardware acceleration, under X11 (openbox wm), with “mpv filename.mp4”

I git-cloned his repo, selected orangepizero3, changed nothing, kept all his repo’s patches, chose bookworm minimal, Linux edge 6.7.12

i installed lightdm and xorg, then jock’s package repo for ffmpeg-v4l2requedt, then installed mpv (official bookworm package).

the 720p and 1080p videos played fine, with 5% cpu

It is weird for me

update: to play in a screen not being used by x11, like a LCD TFT, use ctrl-alt-f2 to switch the keyboard into the tty in the LCD

Play any low res video with vlc, then quit it (I see that mpv can't play without this previous step, for me)

Play with mpv --vo=drm --video-connector=2.SPI-1 yourvideo.mp4

many thanks to both!!
