Hardware video acceleration with recent armbian/mainline kernel (Kodi)

[XXXBold]

Hello everyone

 

Just would like to start a discussion about the current state of video acceleration (decoding only, h.265/h.264/av1).

The soc (rk3588) recently got mainline support for these features in 7.0: https://gitlab.collabora.com/hardware-enablement/rockchip-3588/notes-for-rockchip-3588/-/blob/main/mainline-status.md

 

Has anyone tested this on a OPI5 already, especially using Kodi? Does this work ootb there now?

 

Regards,

XXXBold

I have tested the following PR: https://github.com/mpv-player/mpv/pull/14690

 

It needs compilation of a custom ffmpeg (linked in PR) + mpv (with this PR). My findings are reported here: https://github.com/mpv-player/mpv/pull/14690#issuecomment-4159253319

 

Overall it is working, haven't tested Kodi yet.

For context, he is talking about:

https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/20847 

 

There are many ffpmpeg options. Which ffmpeg did you use?

https://code.ffmpeg.org/Kwiboo/FFmpeg/src/branch/v4l2request-v3

https://code.ffmpeg.org/Kwiboo/FFmpeg/src/branch/v4l2-request-n8.1

 

And which debian/ubuntu version did you use? Which ffmpeg is included in that distribution?

I'm using Ubuntu 24.04 noble armbian distribution, the branch I used for ffmpeg is https://code.ffmpeg.org/Kwiboo/FFmpeg/src/branch/v4l2request-v3

 

The ffmpeg included in the distribution does not matter, but regardless it is version 6.1.1. The mpv is built against the locally compiled ffmpeg with libplacebo from https://code.videolan.org/videolan/libplacebo.git

I am glad that it's possible to use a different ffmpeg version than what the distribution expects.  (it gives me hope of installing it in Trixie, instead of changing over to the newest Ubuntu)

 

Did you install the locally compiled ffmpeg at OS level, or did you keep it in a folder within your /home/username/...?
