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.
