Gstreamer and libcamera `WARNING: erroneous pipeline: no element "libcamerasrc"`

Question

Running a gstreamer pipeline using libcamerasrc results in this error:

gst-launch-1.0 libcamerasrc gives WARNING: erroneous pipeline: no element "libcamerasrc"

Answer 1

The problem is that libcamerasrc support isn't in the standard installation of libcamera, it is in the arducam installation:

wget -O install_pivariety_pkgs.sh https://github.com/ArduCAM/Arducam-Pivariety-V4L2-Driver/releases/download/install_script/install_pivariety_pkgs.sh
chmod +x install_pivariety_pkgs.sh
./install_pivariety_pkgs.sh -p libcamera_dev    <-- This contains support for gstreamer's libcamerasrc

Look for proof that the arducam package is installed:

$ sudo apt show libcamera0

Package: libcamera0
Version: 0~git20230724+ad9428b4-1
Status: install ok installed
Priority: optional
Section: libs
Source: libcamera

And here is the real proof: gst-inspect-1.0 libcamerasrc
