libcamera under Debian Trixie #17
Description
Hello,
I'm trying to get the webcam on my new XPS 13 9350 working under Debian 13 (Trixie).
I've installed all four Intel projects.
I can see the many video devices under /dev/.
However, Firefox displays all the /dev/video* devices instead of just a single Intel MIPI device.
Is it necessary to patch libcamera? I see there's a libcamera subdirectory in the repository, but there are no instructions on how to build it.
Thanks.
