Hello,I encountered the same problem as you. The problems are as follows:The solution is as follows:
1.2.注：!!The current python3-libcamera version (0.2.0+rpt20240418-1) has as dependency: libcamera0.2 (>= 0.2.0+rpt20240418)
The current libcamera0 version is0.2.0+rpt20240418-1.My libcamera0.2 is obviously older. But I found that:There is no version I want in apt, so I reinstalled it all using the source code in the way described in the official Raspberry Pi documentation.https://pidoc.cn/docs/computers/camera- ... Alibcamera
3.4.5.6.7.8.9.Then I built rpicam-apps using the same method. I won’t go into details about the code here. Just download it from the source code as above. The official documentation has a detailed introduction. https://pidoc.cn/docs/computers/camera- ... picam-apps
Finally, I succeed in solving the problems.
Code:
