There are 10 repositories under v4l2 topic.
WebRTC streamer for V4L2 capture devices, RTSP sources and Screen Capture
RTSP Server for V4L2 device capture supporting HEVC/H264/JPEG/VP8/VP9
ZBar is an open source software suite for reading bar codes from various sources, including webcams. As its development stopped in 2012, I took the task of keeping it updated with the V4L2 API. This is the main repository for it. There's a clone at at LinuxTV.org, and another one at gitlab.
obs studio output plugin for Video4Linux2 device
Bootable 64-bit Gentoo image for the Raspberry Pi4B, 3B & 3B+, with Linux 5.4, OpenRC, Xfce4, VC4/V3D, camera and h/w codec support, weekly-autobuild binhost
Turn your Raspberry Pi into a low-latency home security camera by using native WebRTC with the v4l2 hardware H.264 encoder and the software-based OpenH264 encoder for live video stream.
Camera controls for Linux
Cross Platform Rust Library for Powerful Webcam/Camera Capture
Add filters (background blur, etc) to your webcam on Linux.
The Linux SDK for The Imaging Source cameras.
A rockchip-mpp V4L2 wrapper plugin for chromium V4L2 VDA/VEA
uvc-gadget with resolution changing and video controls
Fmp4streamer streams your V4L2 camera directly to any browser and media player as MP4 (H264).
A video input (V4L2) to NDI converter that works with Raspberry Pi (32-bit and 64-bit), and Intel/AMD CPUs
ROS 2 node for libcamera supported cameras (V4L2, Raspberry Pi Camera Modules)
This project is based on rk3399 mpp librarys and aims at publishing camera data into RTMP server.
Code examples for running V4L2 USB Cameras on NVIDIA Jetson Developer Kits
Face tracking, bg removal, crop, zoom, record & replay, and more webcam mods
A uniform library wrapper for input from V4L2,Freenect,OpenNI,OpenNI2,DepthSense,Intel Realsense,OpenGL simulations and other types of video and depth input..
RTSP video streaming server implementation based on Live555 and FFmpeg
This project contains sample OpenCV application code as well as V4L2 helper library to access camera devices in OpenCV. This code helps to achieve high framerates from cameras in OpenCV. This project gives better results than the VideoCapture class in OpenCV. This source code is only compatible in Linux.
