Introduction to rockchip-multimedia ppa for ubuntu jammy

#21

Are there any repos for RebornOS / Archlinux around?

#22

You may find some of these packages in aur.

#23

hey @amazingfate , i’ve installed your ppa on ubuntu jammy, but when i do gstreamer-inspect i only see decoders, not encoders, is that intentional?

root@b32ed7ddddff:/app# gst-inspect-1.0 | grep rock
rockchipmpp:  mppjpegdec: Rockchip's MPP JPEG image decoder
rockchipmpp:  mppvideodec: Rockchip's MPP video decoder
rockchipmpp:  mppvpxalphadecodebin: VP8/VP9 Alpha Decoder

i’ve installed inside docker to make it repeatable

FROM --platform=linux/arm64 ubuntu:jammy as base
# Set the working directory to /app
WORKDIR /app

# gstreamer
RUN apt-get update && export DEBIAN_FRONTEND=noninteractive \
    && apt-get -y install --no-install-recommends \
    \
    gstreamer1.0-tools \
    gstreamer1.0-plugins-base gstreamer1.0-plugins-good \
    gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly \

    python3-gi python3-gst-1.0 \

    && apt-get clean -y && rm -rf /var/lib/apt/lists/*

# gstreamer rockchip
RUN apt-get update && export DEBIAN_FRONTEND=noninteractive \

You need to install rockchip-multimedia-config to set the correct dev permission.

sudo apt install rockchip-multimedia-config
rm ~/.cache/gstreamer-1.0/registry.aarch64.bin
gst-inspect-1.0 rockchipmpp
#25

Not accesible yet for Ubuntu 23.04?

#26

No plan to support non-LTS releases.

#27

Very bad decision

#28

I will not upgrade my ubuntu release until the next LTS, so it is a very good decision for me.

just to post a solution – in my case i was using armbian with 6.3 kernel, to have encoders works one need to use legacy kernel 5.10.110-rockchip-rk3588 and then encoders in gstreamer shows/work

when the input is gray8, rga says it is not supported, does that mean monocolor camera with rk3588 won’t achieve higher fps due to no hardware support for videoconvert?

#31

You may try other color conversion method. I’m not familiar with this.

#32

I installed ffmpeg but it doesn’t work :frowning:
(I use edge kernel 6.1 if it matter)

Make sure you are running kernel from rockchip. You don’t have mpp kernel driver right now.

#36

but I have no /dev/mpp_service device

I checked journalctl and…

This is a mainline kernel, which doesn’t have mpp kernel driver.

#38

Mainline is same as current kernel in armbian, I assume.
I also assume, that I need to use legacy 5.10 kernel.
I will try to downgrade and hope that will fix issue…

#39

which kernel does have mpp driver
how to check?
