Perfect, thanks! I will look into that.

I have had some success in getting a single image using this command at the command prompt:

v4l2-ctl --device /dev/video11 --set-fmt-video=width=1280,height=720,pixelformat=NV21 --stream-mmap --stream-to=frame2.yuv --stream-count=1

I can import it into the YUView utility and see the image, but ...

Thanks!

What I did was go back up to the sdk root and do a "make clean" which deleted everything. Then I did the ./make -lunch & ./make to rebuild everything.

Then I went back through the menuconfig process and everything compiled. I will test the new image tomorrow.

I also have no idea why it ...

And from the log file for the compile:

Checking for function "ngettext" : NO
Running compile:

Trying this out, it seems to get stuck on this "library intl found: NO" error:

Run-time dependency libffi found: YES 3.4.4

Checking for function "ngettext" : NO

Thanks! I will try this. I think I was probably missing the "clean" step. I will post the results.

Coming back to this after a while. I did manage to get the "v4l2_test" utility to work and I could convert the YUV file using a tool on my desktop computer.

However, I have been trying to follow the instructions here for installing the v4l2 tools https://wiki.luckfox.com/Luckfox-Pico/CSI-Camera ...

Great, thanks! I'll try that!

I have tried that. When I set it to that in profile I get:

• Wed Feb 28 07:28:21 UTC 2024

Where as the actual date/time where I am is:

• Tues Feb 28 13:28

I am not sure if there is another time offset somewhere?

Perfect, thank you very much! I will give these a try.
