How To Use the Raspberry Pi Cameras with Bullseye – Guide
The new Raspberry Pi OS is based on Debian 11 (Bullseye), and the traditional raspistill and raspicam camera commands have been replaced by a new set of open source tools designed to get the most out of all official Raspberry Pi cameras.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 Linux, Android, and ChromeOS support library that was first provided to the Raspberry Pi through an earlier Raspberry Pi OS. Libcamera gained popularity as a result of the enhancements made to Bullseye, which uses Libcamera to provide 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. We use a Raspberry Pi 4 4GB running Bullseye to guide you through some of the most frequent commands, switches and a unique way to stream live video over a network using your Raspberry Pi. ..
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.
To keep the viewport open while taking pictures, use the “argument” option. ..
Libcamera-jpeg is a simple “point and shoot” camera that can be used to quickly capture an image. ..
- 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. ..
- Press the button to take a photo and save it as still-test.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.
The libcamera-still command creates a PNG image of a still image.
- Use the –datetime switch to capture an image. This will save the image as a JPG using the MMDDhhmmss date format as the filename.
Capturing Video
LibCamera-Vid is a library that can capture high definition video in h264, mjpeg and yuv420 formats. ..
- 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 must first browse to the folder containing the file and right click on it. Then select VLC Media Player from the list of options. If the file is not playable with VLC Media Player, there may be a problem with the audio or video codecs. ..
video streaming
LibCamera-VID allows streaming of video over a network. This could be used for example for a pet camera or a bell. ..
- 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.
This command sets up a camera and starts recording video. It listens on port 8888 and records video.
- On another computer, open VLC and go to Media » Open Network Stream and select the media you want to watch.

Click on the link in the top left corner of the window to enter your address and click on the “Submit” button. You will be asked to enter a password, which you will remember for future uses.
There will be a delay between when the camera sees the video and transmits it to VLC.
TCP/H264: 8888
