uvgRTP 2.0: Open-Source RTP Library For Real-Time VVC/HEVC Streaming

Real-time video transport plays a central role in various interactive and streaming media applications. This paper presents a new release of our open-source Real-time Transport Protocol (RTP) library called uvgRTP (github.com/ultravideo/uvgRTP) that is designed for economic video and audio transmission in real time. It is the first public library that comes with built-in support for modern VVC, HEVC, and AVC video codecs and Opus audio codec. It can also be tailored to diversified media formats with an easy-to-use generic API. According to our experiments, uvgRTP can stream 8K VVC video at 300 fps with an average round-trip latency of 4.9 ms over a 10 Gbit link. This cross-platform library can be run on Windows and Linux operating systems and the permissive BSD 2-Clause license makes it accessible to a broad range of commercial and academic streaming media applications.
