uvgRTP is an Real-Time Transport Protocol (RTP) library written in C++ with a focus on simple to use and high-efficiency media delivery over the Internet. It features an intuitive and easy-to-use Application Programming Interface (API), built-in support for transporting Versatile Video Coding (VVC), High Efficiency Video Coding (HEVC), Advanced Video Coding (AVC) encoded video and Opus encoded audio. uvgRTP also supports End-to-End Encrypted (E2EE) media delivery using the combination of Secure RTP (SRTP) and ZRTP. According to our measurements uvgRTP is able to reach a goodput of 600 MB/s (4K at 700fps) for HEVC stream when measured in LAN. The CPU usage is relative to the goodput value, and therefore smaller streams have a very small CPU usage.

uvgRTP is licensed under the permissive BSD 2-Clause License. This cross-platform library can be run on both Linux and Windows operating systems. Mac OS is currently not supported, but contributions are welcome to help with this. For SRTP/ZRTP support, uvgRTP uses Crypto++ library.

uvgRTP is still in its beginning stages, meaning that new bugs are still being found and fixed. You can follow the progress on bug fixes here.

Currently supported specifications:

• RFC 3350: RTP: A Transport Protocol for Real-Time Applications
• RFC 7798: RTP Payload Format for High Efficiency Video Coding (HEVC)
• RFC 6184: RTP Payload Format for H.264 Video
• RFC 7587: RTP Payload Format for the Opus Speech and Audio Codec
• RFC 3711: The Secure Real-time Transport Protocol (SRTP)
• RFC 6189: ZRTP: Media Path Key Agreement for Unicast Secure RTP
• Draft: RTP Payload Format for Versatile Video Coding (VVC)

The original version of uvgRTP is based on Marko Viitanen's fRTPlib library.

• Built-in support for:
  • AVC/HEVC/VVC video streaming
  • Opus audio streaming
  • Delivery encryption with SRTP/ZRTP
• Generic interface for custom media types
• UDP hole punching
