libGuvc

libGuvc – USB Video Class Gadget Library for Embedded Linux libGuvc is RidgeRun’s USB Video Class (UVC) Gadget Library that abstracts the complexity of building USB-compliant virtual camera devices on embedded Linux systems. This platform-agnostic library allows developers to transform embedded devices into USB webcams, supporting UVC video streaming with formats like YUY2, MJPEG, and H.264—all with minimal integration effort. Instead of managing low-level UVC protocol details, you focus on your application, while libGuvc handles UVC communication, stream negotiation, video buffer management, and driver stack interfacing. Key Features: Supports Popular Video FormatsStream in YUY2, MJPEG, and H.264 for compatibility with a wide range of host systems and software. Extension Unit SupportEasily add custom controls and functionality via UVC Extension Units. Flexible Transport OptionsWorks with bulk and isochronous USB endpoints, providing adaptability for different USB hardware. Efficient Buffer HandlingSupports User Pointer and MMAP buffer types for optimized memory handling. Cross-Platform IntegrationUse with any embedded Linux device that has a UVC Gadget driver enabled—no kernel changes needed. Example Use Case: An industrial camera solution based on NXP i.MX8 needs to stream processed video over USB to a host PC running standard video software. With libGuvc, the development team sets up the embedded board to appear as a UVC-compliant webcam, transmitting MJPEG video and exposing extension unit controls to adjust focus and zoom—all without writing UVC protocol logic from scratch. What’s Included: RidgeRun’s libGuvc source or binary package C API documentation and integration guide Sample applications for streaming and control setup Optional 11-hour Embedded Software Support package Supported Platforms: Any Linux-based embedded system with UVC Gadget support Tested on: NXP i.MX6 / i.MX8 NVIDIA Jetson (Nano, Xavier NX, Orin) Texas Instruments Why RidgeRun?
