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.

- Signaling with Session Initiation Protocol (SIP)
- 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
- All settings are recorded to the disk and loaded at startup
Other

See FEATURES.md for more detailed description of features.
uvgComm relies on following external libraries:
- Kvazaar for HEVC encoding
- OpenHEVC for HEVC decoding
- libyuv for video input processing
- Opus for audio coding
- Speex DSP for audio processing
- uvgRTP for media delivery
- Crypto++ for delivery encryption (optional)
uvgComm uses CMake to build itself and missing dependencies with minimal effort from the developer, see BUILDING.md for build instructions.
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.
