== imx415 60fps

avaf · October 16, 2024, 11:46pm

I recently noticed Radxa updated the driver and the tuning file for 60 FPS (1920x1080).
I tried it, but unfortunately, the tuning file imx415_RADXA-CAMERA-4K_DEFAULT.json is not working properly. Maybe you did not push the latest fix?

Note:
i can get 60 fps without the tuning file.

@ken
Please point to the source code you are using for the engine. I can’t pull your deb packages, it breaks my setup. I need to build the engine natively.

FYI, 3840x2160 mode works fine, 1920x1080 mode does not.

I have 60 fps fully working: Radxa Camera 4K (IMX415) at a real 4K@60 on ROCK 5B – out-of-tree driver, no kernel rebuild

I tested your driver on Rock 5C-lite (8 cores unlocked / missing AVS1 decoder). I get ~55 fps (3840x2160) displayed on screen, but unfortunately the image is dark with the current iqfile (the one which works with 30fps).

I built in-tree kernel module driver, 6.1.43-rk3588-v4l2-cam. Built only the kernel.

Which iqfile and kernel version are you running? Can you please attach the iqfile that runs fine with UHD 60fps?

Update:

I forgot to rename the iqfile to imx415-60fps.

And thanks for your work!

I use:

gstreamer-rockchip PR#84
gstreamer-rockchip PR#85
RKAIQ-2026_09_08
IQ file from Radxa OS – keep its name, imx415_RADXA-CAMERA-4K_DEFAULT.json

gst-launch-1.0 -e \
  v4l2src device=/dev/video11 io-mode=dmabuf \
  ! video/x-raw,format=UYVY,width=3840,height=2160,framerate=60/1 \
  ! queue max-size-buffers=2 max-size-bytes=0 max-size-time=0 \
  ! mpph265enc rc-mode=cbr bps=35000000 gop=60 max-pending=4 \
  ! h265parse ! matroskamux ! filesink location=4k60.mkv

This results in true 60 fps on my Rock 5B

I use a slightly different iqfile. Renaming it to correct name solved it in my case. Rock 5C lite has no GPU (or at least a working one, but luckily my GPU works which is good for testing, it oscillates a bit) and some missing encoder but H265 looks fine. CPU% 70~80 (rendering 4k) and 12% if encoding.

Feedback with my rock 5c-lite setup:

a) It works, most of the times!

b) First time running and grabbing frames gives some csi errors, just like described in 1188 Mhz

v4l2-ctl -d /dev/video11 --set-fmt-video=width=3840,height=2160,pixelformat=NV12 --stream-mmap=4 --stream-skip=500 --stream-count=1 --stream-to=/dev/null

<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 62.68 fps, dropped buffers: 6

<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 63.37 fps, dropped buffers: 6

c) Second time running (without booting) and grabbing frames:

v4l2-ctl -d /dev/video11 --set-fmt-video=width=3840,height=2160,pixelformat=NV12 --stream-mmap=4 --stream-skip=500 --stream-count=1 --stream-to=/dev/null

<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 90.03 fps
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

Forum always resize image to 1920x1080 and can’t render faster than this:

d) running third time, csi errors…

Update:

Encoding 90 fps, and image looks normal (better than rendered on screen)
