uvgComm

uvgComm is a High Efficiency Video Coding (HEVC) video call software written in C++ and built on Qt application framework. uvgComm aims to provide a testbed for novel video conferencing solutions, while also advancing the field of Real-Time Communication (RTC). uvgComm is licensed under permissive ISC-license.

uvgComm was previously called Kvazzup. uvgComm is under development and new features will become available.

Current features

  • Negotiation with Session Description Protocol (SDP)
  • Connectivity with Interactive Connectivity Establishment (ICE)
  • Delivery with Real-Time Transport Protocol (RTP)

Media

  • HEVC codec for video
  • Opus codec for audio
  • Support for 13 different camera input pixel formats
  • Option to disable audio and/or video
  • Screen sharing

Analytics and Settings

  • A statistics window for monitoring call quality
  • Full customizability of both audio and video processing in settings
  • Automatic selection of best media settings with option for live manual adjustment

See FEATURES.md for more detailed description of features.

Building uvgComm

uvgComm relies on following external libraries:

uvgComm uses CMake to build itself and missing dependencies with minimal effort from the developer, see BUILDING.md for build instructions.

Setting up a SIP Server

uvgComm has been tested together with Kamailio Open Source SIP Server. Easy to follow instructions are hard to come by on the internet, so we provide our own instructions for setting up Kamailio.
