ERROR Serializer control can't deserialize ControlList: unknown ControlInfoMap

I wonder what is causing this error:

I belive it is coming from Libcamera. Appreciate anyone can help me out. I have been with this error for the past week.

@sridzuan
what command did you use
Maybe you are using libcamera_python, this issue was fixed yesterday.

How to use code to access libcamera(C++/Python)

Hi, Everyone Regarding the libcamera python library incompatibility with libcamera-dev 0.0.7 version, we have found the problem and solved it. We updated the version number of the libcamera python library to 1.0.3. This version only supports Bullseye Raspberry Pi systems with kernel version greater than or equal to 5.10.92. You can download it from the link below.

I use the exact code https://github.com/ArduCAM/PTZ-Camera-Controller/blob/master/FocuserExample.py

Will try the latest version. Appreciate your efforts.

The camera doesnt work. I am going back to 1.0.2, piping to null

hi, @sridzuan

To use libcamera python 1.0.3 version library, you need to reinstall libcamera-dev deb package.

@yang

reinstall libcamera-dev deb

I followed How to reinstall libcamera*? - Raspberry Pi Forums
now I am having:
[0:01:21.562698268] [1305] INFO Camera camera_manager.cpp:293 libcamera v0.0.0+3572-e13ccdd5
Segmentation fault

Normally this occurs when the library cannot detect the camera. Cheese is running fine with expected image.

more clues:
libcamera-hello: symbol lookup error: /usr/local/lib/libcamera_app.so: undefined symbol: _ZN9libcamera8controls5draft9AfTriggerE

Its frustrating now nothing works!

hi, @sridzuan

You need to install our libcamera-dev deb package. You can refer to the link below to install:

Works like a charm, enjoying this camera.
