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. Furthermore, uvgRTP can be used to transport *Visual Volumetric Video-based Coding (V3C)* encoded volumetric video. ugvgRTP also supports *End-to-End Encrypted (E2EE)* media delivery using the combination of *Secure RTP (SRTP)* and ZRTP. uvgRTP has been designed to minimize memory operations to reduce its CPU usage and latency.
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 also supported, but the support relies on community contributions. For SRTP/ZRTP support, uvgRTP uses the [Crypto++ library](https://www.cryptopp.com/).

To get started using uvgRTP, check out [usage](USAGE.md) file which contains a step-by-step tutorial for using uvgRTP. To see uvgRTP in action, the [examples](examples) folder contains many working examples to illustrate how to use uvgRTP in variety of situations. For a more detailed description, check the [documentation](docs/README.md) where you can find info on advanced topics and descriptions of all uvgRTP flags.
We warmly welcome any contributions to the project. If you are considering submitting a pull request, please read [CONTRIBUTING.md](CONTRIBUTING.md) before proceeding.
