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](https://researchportal.tuni.fi/en/publications/open-source-rtp-library-for-high-speed-4k-hevc-video-streaming) 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](https://www.cryptopp.com/).
We warmly welcome any contributions to the project. If you are thinking about submitting a pull request, please read [CONTRIBUTING.md](CONTRIBUTING.md) before proceeding.
We also have an easy to use performance test framework for benchmarking uvgRTP against FFmpeg and Live555 on Linux OS. The framework can be found [here](https://github.com/ultravideo/rtp-benchmarks).
