Robotweax SRT.
An independent open-source Secure Reliable Transport library for video streaming, broadcast and networked applications.
Open source on GitHub · MIT License
The Robotweax SRT project.
Robotweax SRT is an independently developed implementation of the established Secure Reliable Transport protocol — not a fork of the reference implementation. The portable C++20 library is available on GitHub under the MIT License. Published version 0.3.0 targets the public SRT 1.5.7 API and supports Linux, macOS and Windows.
View the GitHub projectVersion 0.3.0 is a pre-1.0 release with documented compatibility and qualification limits. It is neither a universal replacement for every libsrt deployment nor independently security-certified.

One protocol. Many video applications.
SRT is an already available open-source transport protocol for low-latency live video and audio. It addresses challenges such as packet loss, jitter and changing network conditions, making it a foundation for video transport well beyond traditional broadcast workflows.
Low Latency
Low-delay video transport for live workflows. Latency can be configured to suit the connection and application.
Reliable Transport
Packet recovery and jitter handling help streams travel across changing network conditions.
Secure Networking
Encrypted transport over IP networks. Video formats and codecs remain independent of the transport protocol.
For the whole video streaming industry.
Broadcast & Live Production
Transport video from remote sources into production environments and connect locations.
Streaming Platforms & Cloud
Video ingest, forwarding and processing as part of distributed streaming infrastructure.
Connected Applications
Bring video where it is needed, including remote observation and analysis. Looking ahead, this can also support video links to robotics systems.
Experience developing SRT.
Marc Cymontkowski, Robotweax founder and managing director, played a leading role in developing Secure Reliable Transport at Haivision. Robotweax now brings that video-processing and networking experience to an independent SRT implementation, AI and automation.
