We have wrapped the simple libcamera python library.
It allows you to access libcamera through python code, and realize tasks such as turning on the camera, controlling the camera, and turning off the camera.
In addition, we have also written a simple libcamera C++ example.
Through this example, you can quickly run the camera, and you can view the example source code to understand the specific process of libcamera operation.
When running python capture_demo.py I get the following error:
pi@raspberrypi:~/libcamera-python $ python capture_demo.py

For users using libcamera on kernel version 5.10.92 (2022/01/28 SD Card Image), please use libcamera python wrap in this package: libcamera_python-1.0.2.zip - Google Drive
Hi, Iāve got the auto focus camera following the setup steps for that I can take photos with libcamera-still.
However what Iām trying to do it take a series of photos and programatically adjust the focus inbetween shots. The plan is that Iāll then use the resulting pics for focus stacking. Iād like to take the photos with as short a delay between them as possible.
When I try to use this wrapper, I get nowhere. If I install the other driver with shared in your instructions above, I canāt take photos at all, not even with the command line. Are the 2 compatible? Any suggestions on what Iām doing wrong?
What version of raspberry pi are you using? If the system version is 5.10.92, please refer to the instructions below to download the libcamera python library.
Currently this library is not compatible with 64-bit Raspberry Pi systems. We will make a library compatible with 64-bit systems. Thank you for your reminder.
Do I need to uninstall the other driver? If so, how do I do that? The install_pivariety_pkgs.sh script doesnāt seem to have a āremoveā option. Do I need to do a fresh install of the OS?
If you upgrade from kernel version 5.10.92 to 5.10.103, you do not need to reinstall libcamera. Install libcamera python library version 1.0.2 directly.
If you upgrade to 5.10.103 from a kernel version prior to 5.10.92, you will need to reinstall libcamera. Then install libcamera python library version 1.0.1.
To reinstall libcamera, just execute the install_pivariety_pkgs.sh script again, the higher version will overwrite the lower version.
Alternatively, you can uninstall using the āsudo apt removeā command. Then install libcamera again.

But Iāll have a look at it tomorrow.
It looks like data.imageData gets the image, how do I save that to a file? what format is it? JPG? RAW?
Hello @yang and the support team. Thank you for this thread. I was able to finally get libcamera and the python wrapper working with your demo python files (full_resolution_demo.py, capture_demo.py, and controls_demo.py). Iāve been making a few alterations, but what I donāt see is any command to tell the imx519 to autofocus. Is there a set command I can send to it that tells it to autofocus, or is there code somewhere I can see how to make it autofocus?
Hello @yang and support team. Thank you for the autofocus code, that will be very helpful once this camera is up and running. And I really want to get this working because I am very interested in upgrading to Hawk-eye if possible (I have already pre-ordered one).
I believe I have followed all the installation instructions to the letter, but still I am unable to get the demo apps to run. I can run libcamera-hello and other libcamera options, but this is what I am currently getting when I try and run your full_resolution_demo.py and other demos from inside libcamera_python:
python3 full_resolution_demo.py

What version of the Raspberry Pi system are you using? Different versions of the system need to install different versions of the libcamera python library.
