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/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
