Kodi's ffmpeg is using function deint_v4l2m2m_destroy_context, which is part of another patch, which I didn't have: vf_deinterlace_v4l2m2m

I am compiling it now

 

Result: mpv takes the VAAPI route, then software decoding

Hmm, when I take another look at my previously posted ffmpeg.spec addition, I see  that I also carry a patchset with the name like that from a branch of @jernej github. Furthermore, I see that I also apply other patches from the v4l2-drmprime-n5.1.2 branch. Do you have similar patches in your portfolio?

Yes. I have applied that drmprime patch also.

 

I think it is a drm or gbm issue now.

What would be the closest orange pi to orange pi zero? Ideally it would be H3, with both HDMI and analog video.

Sorry, but I don't quite understand what you're asking for here. When it comes to improving the display subsystem, I would start by rebuilding my kernel package. Since you have confirmed that LibreElec works, my first approach would be to apply all relevant LE patches. But I understand that it is apparently not so easy to implement with your build system.

Sorry, but I don't quite understand what you're asking for here. When it comes to improving the display subsystem, I would start by rebuilding my kernel package.

what I meant is: I want to buy an orangepi H3 with HDMI port, so that I see if there's any difference in hardware decoding.

But the ultimate goal is that I get hardware decoding in analog video... it is possible, because Kodi does it.

 

I has been a very long time since I used RedHat... I used yum ... I will see whether "dnf builddeps" has an equivalent in Debian

 

I found in this discussion that: if ffmpeg hardware decoding works with "-f null -", but fails to present the video (my situation), then the problem might be the display driver:

Another important variable is the way mpv was configured before compile. Anyone who got it working, check the first few lines of running MPV. For example (something I found in the mpv github):

With regard to the hardware decoder, this will not provide any new insights. For the video decoder it is only relevant that the subsequent display pipeline can process the decoder output format. Be it GBM, Wayland, Xwindow or /dev/null.
See here for comparison a gstreamer video pipeline (gst-play-1.0-pipeline.pdf). It is always identical, regardless of which display pipeline (GstXvImageSink) ultimately comes to fruition. The decoder component (v4l2slh264dec) is backed by the respective hardware and is unmodified interchangeable as long as v4l2-compliance shows sufficient driver conformity.

No, the ultimate goal is to compose a video pipeline that is backed by a hardware decoder and to have a display pipeline that can display the format provided by the video pipeline in a hardware-accelerated manner.

If I keep seeing the long dependency lists that are given to install when it comes to building a software, I would guess that it does not exist. But since this is about the kernel package, I don't see the problem here because it is self-contained and does not require any external dependencies. I see here rather the problem of using newly built kernels comfortably parallel in Armbian. This is due to the boot method and the way Armbian installs its kernel (a single kernel, not multiple kernels in parallel). But this can be changed, as I have already demonstrated several times in other forum threads.

This works because the subsequent display pipeline (dev/null) can handle any format.
The display driver is only one part of the display pipeline, but probably the component that does not yet provide all the necessary prerequisites. This will certainly be added in LE with their kernel patches so that they can use a hardware-accelerate display pipeline. A display pipeline has no business with video decoding, we're not in x86 architecture, it deals only with already  decoded content.

Thank you… I will try with more LibreElec patches this week.

 

but LibreElec’s windowing system is GBM, not X11… so that’s a thing that I need to follow… somehow.

You want a working GBM as the first step. An application can use the APIs provided by the kernel via GBM. It becomes the master user of the drm/KMS, i.e. if e.g. Kodi uses the display subsystem via GBM, it is the only user who has access to it. Other graphics applications will not be able to use the display subsystem at the same time. A desktop environment framework accesses the display subsystem using the same kernel APIs as GBM, and therefore becomes the master of drm/KMS. However, it manages the display subsystem resources so that multiple applications can use them simultaneously. For example, Kodi can be displayed in one window and a web browser in another window at the same time.
When it comes to choosing a desktop environment, Xwindow is a bad choice. It was developed for x86 architecture and therefore cannot deal efficiently with these new requirements due to its design. Their developers at that time also recognized this and therefore developed Wayland from scratch. So when it comes to efficiently using a video pipeline in combination with a display pipeline, a desktop environment with Wayland backend is the first choice.
But the good thing is, nowadays the majority support in current mainline is already available out-of-the-box. So in order to support a particular device, it is only necessary that a mainline kernel with the necessary drivers is available and everything else is just generic up-to-date mainline software. For your device you have confirmed that LE works with a mainline kernel, so all necessary code should be available, only it is not yet integrated out-of-the-box into the mainline kernel.

Hi,
sorry to jump in on this thread, but I recently also tried to play hardware accelerated video (preferably on a virtual terminal without X11/Wayland) on my Pine A64 with current Armbian image (derived from Ubuntu 23.02). Unfortunately no method seems to work. Am I doing something wrong? What would be the "easiest" way to get mainline hw accelerated video decoding on A64? Is there another popular general purpose distribution I could try (except LibreELEC with Kodi)?

 

Kernel is 5.15.93-sunxi64 and has cedrus modules:
 

lsmod | grep cedrus

Gstreamer is version 1.20, and it seems to have provide required codecs (after installing gstreamer1.0-plugins-bad).

Unfortunately gst-play doesn't work, it completely freezes my Pine64 (not even Ctrl-Alt-Delete works anymore) after "Redistribute latency...".

So what is going on here? Am I missing a package or kernel module (concerning drm?)? Or do I need an ffmpeg with `--enable-v4l2-request`? And/or an libva-v4l2-request? Where do I get one that compiles with kernel 5.15?

 

Thank you!

IMHO, you're using a software stack that's way too outdated. You are missing features and improvements that have already landed. I'm not an expert in analyzing compliance logs, but if you compare your log to the one provided by @robertoj above, you'll see that your kernel at least lacks features that its provides:

I am using allwinner h3, and you are using A64… I don’t know whether cedrus.ko is right for you.

 

Look in this thread here, whether any kernel module has created a /dev/video device that can input h264, like cedrus can.

 

Run libreeelec again and take note of the kernel version, the kernel modules, and the “.config”, and try to rebuild armbian with those options.

 

https://github.com/robertojguerra/orangepi-zero-full-setup/blob/main/README2.md

 

then you would be at the same spot where I am, with the kernel being unable to display the video due to some gbm missing functionality in my kernel.

[mrfusion]

Thanks for your valuable feedback, both of you!

 

In the meantime I've tried LibreELEC (hw accel in kodi works, but no ethernet or wifi is detect, so not really usable), fedora iot (newer software stack, same problems), and Armbian Rolling Release CI based on Ubuntu Lunar (which also has the same errors; freeze with gstreamer, vaapi-error with kodi, ffmpeg, mpv). I think I'm giving up 😕

[robertoj]

Don’t give up yet.

 

i found this discussion, where retroarch is recompiled, using a libgbm-dev installed just in time… so that Mesa’s (GPU library) gbm component matches exactly with the desired retroarch in that discussion.

 

i have a feeling that we must do the same, but compiling ffmpeg and mpv with the latest available libgbm-dev in place… perhaps just mpv.

 

Usualuser… can you share the mesa and libgbm version you are using?

dpkg -l | grep libgbm or libOSmesa

 

MAYBE there are some useful tips here:

bash: dpkg: command not found...

I'm currently running mesa 23.0.3 and since libgbm is an integral part of mesa,  the version is of course identical. However, the current version is not really important, as the necessary API support is already very mature. It is only important that it is built with the current headers of its BuildRequires to represent the status quo.

Because the API between gbm and mpv does not change, but possibly by applying kernel patches between kernel and gbm (sun4i-drm_dri), it is probably more appropriate to rebuild mesa with the updated kernel headers.
BTW, to get retroarch I would do:

dnf install retroarch

 

[robertoj]

Dpkg and apt won’t work For you… since you are using an rpm/yum/dnf operating system 🤣

 

good point. Mesa may also need recompilation to match a patched kernel (analog video patch), and see whether LibreElec has done anything to Mesa.

 

update: LibreElec patched the linux kernel to add analog video and there’s only one H file affected for this purpose: sun8i_mixer.h but I will still recompile mesa to see if it helps the gbm functionality

I have been unable to work on my armbian projects for a month...

 

Has anybody made any progress about H264 decoding in H3?

 

Thank you!

Media players: mpv and depends on FFmpeg for hardware acceleration (and must be patched together with it). VLC can be set to access libva-v4l2-request directly. Kodi 19.0+ supports hardware acceleration out of the box without any out-of-tree patches.

How does Kodi support this feature? By patched ffmpeg or gsteamer？

I tested armbian + kodi 20.5 with rkdev2 patch on rk3588 linux 6.10， but it seems not used hardware decoder，the cpu load is very high。

But if i play the same video by chromium，the cpu load only use 10%， and i can see it use rkvdec2
