Libcamera
Libcamera is a camera support library. It includes support for cameras that have poor or no support by upstream drivers.
Installation
Install the libcamera package. Install the pipewire-libcamera package to add support for PipeWire.
Usage
For applications that support it, libcamera can be used as is. Some applications need to use V4L2, so libcamerify from libcamera-tools can use LD_PRELOAD to add a virtual V4L2 device that points to libcamera, for example running cheese through this virtual device:
$ libcamerify cheese
Debugging
Running qcam as provided by libcamera-tools can show whether the camera in use is working even if other software does not support the libcamera APIs.
