Introduction to rockchip-multimedia ppa for ubuntu jammy

#12

Thanks. it works now. Btw do you know if I can install v4l2loopback on rk3588 ?

#13

Any idea if hardware encoding is implemented in these pacakges?

#14

You can try v4l2loopback. Hardware encoding is supported by mpp and gstreamer mpp plugin.

#15

Thanks. Btw gstreamer on rockchip is useless as videoconvert is extremely slow on the rockchip and drops a lot of frames… If anyone can do live encoding with videoconvert, please, let me know…

#16

GST_VIDEO_CONVERT_USE_RGA=1 gst-launch-1.0 -e v4l2src device=/dev/video0 ! videoconvert ! waylandsink

#17

Thanks, but still cannot get good fps for videoconvert. Capturing and Encoding HDMI Input maximum 10fps

My command will make use of rga.

Hdmi capture / mpph26xenc latency
#19

thank you for the PPA, I was able to get ffmpeg hardware decoding to work. Do you know what it would take to also make HW encoding of h264/h265 possible?

#20

The ffmpeg package in my ppa doesn’t support mpp encoding. There is another version of ffmpeg supporting encoding: https://github.com/jjm2473/ffmpeg-rk.
You can also use gstreamer to encode.

#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

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.
