Hi! I've found out that the sole fact of having libcamera0 installed breaks Qt (tested with Qt 6). As you can see by comparing the attached files with_libcamera.txt and without_libcamera.txt calls to gst-device-monitor-1.0 Video differ. The attached Qt example exemplifies this. Install qt6-base-dev and qt6-multimedia-dev. Uncompress the tarball and: cd test qmake6 make ./test If your system has a cemra available and libcamera is not installed the application will list it. If libcamera is installed it will not be listed. Somehow libcamera manages to change something on the gstreamer pipeline that breaks other unrelated software. I really think this bug ought to be serious as it breaks unrelated software, but I'll keep that at your discretion. -- System Information: Debian Release: bookworm/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'unstable'), (1, 'experimental-debug'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: arm64 Kernel: Linux 5.18.0-1-amd64 (SMP w/8 CPU threads; PREEMPT) Locale: LANG=es_AR.UTF-8, LC_CTYPE=es_AR.UTF-8 (charmap=UTF-8), LANGUAGE=en_US:en Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled
