Please try sudo apt install mpv, then run mpv av://v4l2:/dev/video-camera0 --vo=gpu --hwdec=rkmpp --profile=fast --vf=scale_rkrga=force_yuv=8bit -v.
This helps determine whether the issue is with the encoder or the camera
Radxa 4K Camera Issues
Hi, I tried the command, ghosting is still there. Those strange video artefacts in my video aren’t there, but the frames still seem to be overlayed on eachother for 1-2 seconds which creates the ghosting / washed out effect.
Please try again: mpv av://v4l2:/dev/video-camera0 --vo=gpu --profile=fast, if the problem still exists, it can be confirmed that the camera is the issue
There is still very faint ghosting which causes slight blurring, but it’s better than before with that command. If the previous command was 100%, this would be 10-20%.
Can you provide the running logs for these two commands?

So I’ve done some more testing with various images and kernels the issue still persists.
HOWEVER the following steps work:
- radxa rock-5c cli bookworm image.
- apt update && apt upgrade
- compile ffmpeg with the following instructions: https://github.com/nyanmisaka/ffmpeg-rockchip/wiki/Compilation
- The following command does NOT work on the first run:
ffmpeg -f v4l2 -i /dev/video-camera0 -vf "fps=30" -s 3840x2160 -c:v h264_rkmpp -rc_mode AVBR -b:v 20M -minrate 10M -maxrate 40M -profile:v main -level 5.1 -f rtsp rtsp://0.0.0.0:8554/stream - HOWEVER changing the h264 profile to high somehow makes it work after a few seconds, subsequent attempts with main profile also start working.

The kde 5c image also started to work, I assume for the same reason (changing profile). I only have 1 camera to test with and not many SD cards to be able to quickly test things. Hopefully the above will help if someone else stumbles upon this. Disappointing result and not sure this can be used in a production setting without proper testing on various boards / cameras.
@stardust might interest you.
Interesting.
I might have a faulty camera then since I’ve tried it on 2 different boards with the same issue.
Thank you for looking into it.
