The problem with os08a10 (Linux)

VIM4 Ubuntu
1

I am trying to use camera os08a10. I already have upgraded system
$ sudo apt update
$ sudo apt full-upgrade
$ sync
$ sudo reboot

But when I ask list device (v4l2-ctl --list-devices) I receive it for this camera:
Amlogic Camera Card (platform:aml-cam):
/dev/video62
/dev/video63
/dev/video64
/dev/video65
/dev/video66
/dev/video67
/dev/video68
/dev/video69
/dev/media0

And I can’t FPS for this camera
v4l2-ctl -d /dev/video69 --list-formats-ext
ioctl: VIDIOC_ENUM_FMT
Type: Video Capture

    [0]: 'BA81' (8-bit Bayer BGBG/GRGR)
    [1]: 'BG10' (10-bit Bayer BGBG/GRGR)
    [2]: 'BG12' (12-bit Bayer BGBG/GRGR)
    [3]: 'GBRG' (8-bit Bayer GBGB/RGRG)
    [4]: 'GB10' (10-bit Bayer GBGB/RGRG)
    [5]: 'GB12' (12-bit Bayer GBGB/RGRG)
    [6]: 'RGGB' (8-bit Bayer RGRG/GBGB)
    [7]: 'RG10' (10-bit Bayer RGRG/GBGB)
    [8]: 'RG12' (12-bit Bayer RGRG/GBGB)
    [9]: 'GRBG' (8-bit Bayer GRGR/BGBG)
    [10]: 'BA10' (10-bit Bayer GRGR/BGBG)
    [11]: 'BA12' (12-bit Bayer GRGR/BGBG)

When I worked with Khadas vim4 without NPU I didn’t see with problem. There was one device in list.

I have khadas vim4 v13 2211.
System - Linux Khadas 5.15.137 #1.7.5 SMP PREEMPT Thu Sep 25 20:37:29 CST 2025 aarch64 aarch64 aarch64 GNU/Linux.

Hello @ilya71

Please check :

Yes. I saw it.

I can write video with fps=30, but I don’t understand how to do video with 60 fps. I asked about it in other topic OS08A10 low FPS and now I have bought khadas vim4 with NPU but I can’t work with 60 fps and I can’t work with this camera as video* (only media0)

it work with gstreamer (60fps), but nothing else work this camera so easily (ffmpeg and v4l2).
