How To Use the Raspberry Pi Cameras with Bullseye – Guide
The new Raspberry Pi OS is based on Debian 11, which is a Debian GNU/Linux distribution that has been designed specifically for the Raspberry Pi. The traditional raspistill and raspicam camera commands have been replaced by a new set of open source tools designed to get the most out of all official Raspberry Pi cameras.
Libcamera is a library that was first provided to the Raspberry Pi through an earlier Raspberry Pi OS, but gained popularity as a result of the enhancements made to Bullseye. The program provides a set of easy-to-use tools to adjust a variety of camera settings (aperture, color balance, and exposure) via a sequence of switches that are activated when the command is delivered.
Connecting and configuring the Camera
In this tutorial, we’ll cover how to connect and configure the camera in a Raspberry Pi. We’ll start by following the tutorial of the configuration up a Raspberry Pi Camera section. Then, we’ll include step 6, which is the final step of the configuration.
Taking pictures
The first step in any coding project is “Hello World”, and libcamera comes with its own in the form of libcamera-hello. We will use this command to ensure that our camera is working.
To stop the camera, enter the command “stop” or “halt” in the terminal.
Run the command again, but this time we will use an option (argument) to force the viewport to remain open. To close the window, click the X or press CTRL + C. Using the preview window in this way provides Raspberry Pi HQ camera users have plenty of time to adjust the aperture and focus of the lens before taking any pictures.
To quickly capture an image, we can use libcamera-jpeg. This tool is a simple “point and shoot” camera.
- Open a terminal and enter the command to start the camera, take a photo and save it as test.jpg
-t 10 -t 5 -t 0 ..
This command will create a test1080.jpg file with a width of 1920 and a height of 1.
advanced options
Libcamera-still is a powerful command for taking still images. It shares many similarities with raspistill, making it easy to use. ..
- Open a photo editor and crop the photo to just show the cat’s face.
- In the photo editor, change the color of the cat’s fur to green.
- Save the edited photo as green-cat-photo.jpg. ..
To capture a PNG image, use the -e option to specify the encoding and ensure the filename ends in .png. We can change the encoding to png, bmp, rgb or yuv420.
LibCamera Still is a command-line tool for capturing still images from video. ..
To capture an image using the camera:
- Open the Camera app and select the desired mode.
- Tap the –datetime switch to activate it.
- Use the camera to take a picture.
- The image will be saved as a JPG with the MMDDhhmmss date format as the filename. ..
Capturing Video
We can capture high definition video in h264, mjpeg and yuv420 formats using libcamera-vid.
- To start the camera, enter the following command: $ sudo apt-get install libcamera-still-dev $ sudo apt-get install libcamera-video-dev $ sudo apt-get install libcamerasoftware4 $ sudo mkdir -p /tmp/test $ cd /tmp/test $ export CMD=“git clone https://github.com/libcamerasoftware/libcamerasoftware.git" $ git clone https://github.com/libcamerasoftware/test.h264
LibCamera-VID is a library for reading and writing H.264 video files. It can read at up to 10000 frames per second, and write files at up to 30 frames per second. ..
To play a file with VLC Media Player on a Raspberry Pi, you need to first browse to the folder containing the file and right click on test.h264 and select VLC Media Player.
video streaming
We can stream video over a network, for example a pet camera or bell using libcamera-vid. This library provides an easy way to stream video over a network, without having to use any third-party software.
- Connect to a computer on the network and open a terminal.
- Configure libcamera-vid to show a preview screen and listen for any IP address to connect to port 8888.
LibCamera-vid is a command line tool that can be used to stream live video from a camera to a remote host. The -t 0 option tells LibCamera-vid to start streaming immediately, and the -inline flag tells it to send the video directly over the network rather than saving it first to disk. The -listen flag tells LibCamera-vid to listen on port 8888 for incoming connections. Finally, the -o tcp: //0.0.0.0: 8888 option tells LibCamera-vid to stream video traffic on that port instead of using the default port for audio (TCP 80). ..
- On another computer, open VLC and go to Media » Open Network Stream and select the media you want to watch.

The delay between when a camera sees something and when it is transmitted to VLC can be a few seconds. ..
