Hi @Balaji

It looks like this is a network problem,
You can try to download the deb installation package manually:

3

I have tried your advice by Downloading libcamera-dev.deb and installed it . By checking
libcamera-still -t 5000 -o test.jpg ,it give libcamera-still: error while loading shared libraries: libcamera.so.0: cannot open shared object file: No such file or directory

5

Please try to install libcamera-dev.deb and libcamera-apps.deb.

6

And please use the following commands when installing:
sudo apt install ./xxx.deb
If you are using the latest bullseye you also need to uninstall libcamera0:
sudo apt remove libcamera0

Dear Sir, Thank you for your kind advice , now I am able to read camera image with libcamera . at last I have an small doubt ,is that pivariety camera can access by Opencv Videocapture method

8

Unfortunately, VideoCapture using opencv can only read RAW data (you can view the format through v4l2-ctl --list-formats-ext).
You can find information about V4l2loopback in the document. It is a compromise method. It uses libcamera to get data and send it to the video node.

9

Is that able to read camera image using raspicam_cv

10

Sir ,I have tried your advice for v4l2loopback to acess camera via opencv . But I have an doudt, v4l2loopback command is has to be run at background to access camera image using opencv in respective program. Incase I exit that command,I could not able to access camera via opencv . is there any solution for this issue

11

Unfortunately, as I said, this is a compromise method. It must run in the background to get data normally.

12

But it makes system slower

13

Then suggest any camera lib to access camera directly in c++ application

14

Yes, it is not the best solution, but it works…

Yes, the best way is to use C++ code to access libcamera directly, you can refer to libcamera-apps, they have complete source code:

15

Is that libcamera-app support opencv for process output image

16

In fact, this is not a problem. Memory data can be easily converted to cv::Mat. Are you looking for C++ code or Python? We have a simple Python wrapper that can be used.

17

kindly provide python wrapper

18

please provide sample or example code for licamera-app to access camera

Hi Balaji

You can download the libcamera python library in the link below, which contains installation instructions and sample code.
