Raspberry libcamerasrc

[horai]

Dear all,

I installed and ran test pipeline for libcamera API on Raspberry Pi:
gst-launch-1.0 libcamerasrc ! videoconvert ! autovideosink

I am getting the following output:
Setting pipeline to PAUSED ...

Does anyone know what the problem might be?
I followed these guides:
https://www.raspberrypi.org/documentation/linux/software/libcamera/README.md

Thank you
