Describe the problem/bug

On the latest raspberry pi os the libcamera functions have been renamed so the image capture does not work.
The commands in the devices/camera.py file need to be updated to deal with this:

line 242

        # Check for rpicam-still first (Bookworm), then fallback to libcamera-still
        camera_cmd = None
        if os.path.exists("/usr/bin/rpicam-still"):
            camera_cmd = "/usr/bin/rpicam-still"
        elif os.path.exists("/usr/bin/libcamera-still"):
            camera_cmd = "/usr/bin/libcamera-still"
        else:
            logger.error("Neither /usr/bin/rpicam-still nor /usr/bin/libcamera-still found")
            return None, None

line 258

            cmd = f"{camera_cmd} " \
                  f"--width {settings.width} " \
                  f"--height { settings.height} " \
                  f"--brightness {settings.brightness} " \
                  f"-o {path_file}"

These changes to my local code fixed the issue.

Versions:

• Mycodo Version: 8.16.2
• Raspberry Pi Version: Raspberry Pi 5 Model B Rev 1.0
• Raspbian OS Version: Debian GNU/Linux 12 (bookworm)

Reproducibility

Please list specific setup details that are involved and the steps to reproduce the behavior:

1. Upgrade devide to bookworm
2. install libcamera-app
3. In MyCodo go to More -> Camera -> Add (selecting libcamera)
4. Click on capture still
5. Error capturing still

Expected behavior

With the fix described above the still was captured

Additional context

happy to push this fix but I did not see a contributor guild and I cant push a branch to your repo

Thank you for the bug report and detailed solution.

I initially used your code, but realized this could potentially negatively impact current users using the libcamera library, so I broke out rpicam into its own library that can be selected. The Cameras page is actually in the process of being deprecated, in favor of using the Camera Function on the Functions page. However, there's currently only one library in use as a Camera Function, and it happens to be libcamera (and as you've pointed out, it's been renamed in the latest OS). So I duplicated the libcamera Camera Function to create a new rpicam Camera Function. This is currently untested, as I don't have a camera connected to any of my dev systems at the moment. If you'd like to test, please let me know if it works for you, otherwise I'll probably get to it in the next week or so.

I forgot to mention how to update the software to the github master branch where the unreleased code is. You can find that guide here.
