Libcamera + OpenCV on a Raspberry Pi 4 with 32-bit Bullseye OS In the new Debian 11, Bullseye, you can only capture live video with a streaming framework, like GStreamer or FFmpeg. It demonstrates how to switch from viewfinder to stills capture This application is intended to be a fully fledged example of an IoT application. Ultimately I'm hoping that we'll be able to use official libcamera packages, and official libcamera python bindings from pip, but I don't think there's anything like that available at the moment. To add a new pipeline handler, create a directory to hold the pipeline code in the src/libcamera/pipeline/ directory that matches the name of the pipeline (in this case vivid). executable file To make it easier to switch existing applications to libcamera Raspberry Pi has provided a set of libcamera-apps.
