PART3
If you got this far and had a successful boot, you will want to extend the partition to use all available space. Unfortunately, you have to do it manually with fdisk or use a script available from well-known distros or a simpler method (resize2fs) while running.
Checking if the camera is recognized

Using the camera
The available tools to grab images from the camera are:
- ffmpeg / ffplay
- gstreamer (need to update some packages)
- fswebcam
Here are some examples:
- 12.3 M mode (10 fps)
ffplay -f v4l2 -pixel_format nv12 -framerate 30 -video_size 1920x1080 -i /dev/video11 -top 0 -left 0
DISPLAY=:0.0 ffplay -f v4l2 -pixel_format nv12 -framerate 30 -video_size 4064x3040 -i /dev/video11
fswebcam --displayfps 1 -S 90 -d /dev/video11 -r 4064x3040 --jpeg 95 -p NV12 - > 4064x3040_1.jpg
- 50 fps mode
ffplay -f v4l2 -pixel_format nv12 -framerate 30 -video_size 2016x1080 -i /dev/video11 -top 0 -left 0
Weston
By default, the image runs on CLI but you can fire Weston for graphical apps.
Type in the command (not from ssh):
weston
Now you can run graphics apps from ssh
If you want weston with command line and windowing, edit .config\weston.ini and comment on the lines that disable bar and window.
If you want to boot with weston, you must manually add the Weston service.
Gstreamer
I was focused on ffmpeg / ffplay, and had gstreamer working fine, but i must have removed some packages, i need to review which one(s).
Looks like the dma-buf patch to fix ffmpeg broken the gstreamer, if you want to use gstreamer try to unzip the file mpp.zip (attached) to a /tmp, install the deb packages with *'sudo dpkg -i *.deb’ and reboot. Unfortunately, you have to make a choice, ffmpeg / ffplay with HW encoder/decoder/acceleration or gstreamer with HW encoder/decoder/acceleration due to the dma-buf patch for ffmpeg.
More about the ffmpeg fix here: ( [FFmpeg] Introduce FFmpeg-Rockchip for hyper fast video transcoding via CLI - #107 by avaf )
mpp.zip (1.1 MB)
try gstreamer:
gst-launch-1.0 v4l2src device=/dev/video11 io-mode=dmabuf ! ‘video/x-raw,format=NV12,width=1920,height=1080,framerate=30/1’ ! glimagesink
Changing camera mode
You have a directory with pre-made modes, you just copy it to the boot.
ls ~/dtb
rk3588s-rock-5c.dtb_IMX477_2016x1080_50fps
rk3588s-rock-5c.dtb_IMX477_2016x1520_40fps
rk3588s-rock-5c.dtb_IMX477_4048x3040_10fps
- 50 fps mode:
cd ~/dtb
rock@rock5c:~/dtb$ sudo cp -vf rk3588s-rock-5c.dtb_IMX477_2016x1080_50fps /boot/dtbs/6.1.43-rk3588-v4l2-cam/rockchip/rk3588s-rock-5c.dtb
‘rk3588s-rock-5c.dtb_IMX477_2016x1080_50fps’ → ‘/boot/dtbs/6.1.43-rk3588-v4l2-cam/rockchip/rk3588s-rock-5c.dtb’
sudo reboot
Check FPS with gstreamer (after you restore/rollback dma-buf ffmpeg fix, see above), fire weston and:
GST_GL_X11_NO_DECORATIONS=1 DISPLAY=:0.0 gst-launch-1.0 v4l2src device=/dev/video11 io-mode=dmabuf ! ‘video/x-raw,format=NV12,width=1920,height=1080,framerate=50/1’ ! fpsdisplaysink video-sink=waylandsink sync=false
Performance / Optimizations
Set performance governor with:
p.sh.zip (407 Bytes)
If you like to be on the edge you can set frequencies and governor to performance and get a boost.
Save the attached file p.sh, set run flag: sudo chmod +x ./p.sh and run with sudo, like this:
rock@rock5c:~$ sudo ./p.sh

Benchmark
After you set performance governor you can run glmark2 to check the score.
- In the main console, run :
