The GitHub repository was created in April 2017, and the project published early 1.2.x releases later that year. The project documentation frames SRT as a UDP-based transport with AES encryption, ARQ loss recovery, optional FEC, rendezvous/firewall traversal, and later socket-group bonding features. The repository includes sample command-line tools such as srt-live-transmit and srt-file-transmit, which helped make the protocol practical for engineers testing live contribution workflows. ### Adoption history SRT grew through the SRT Alliance and through packaging across Unix-like package managers. The upstream README advertises package availability for Debian, Fedora, Ubuntu, Homebrew, vcpkg, and ConanCenter, while the input package facts also list Brew, Debian/Ubuntu, Fedora/DNF, MacPorts, Nix, Arch, and openSUSE package names. ### How it is used CLI users commonly encounter SRT through its sample tools, especially srt-live-transmit for relaying streams, srt-file-transmit for file-style transfer tests, srt-tunnel for tunneling, and srt-ffplay for playback-oriented workflows. ### Why package nerds care SRT matters to package managers because it is both a C/C++ networking library and a set of useful command-line tools, with optional crypto and media-adjacent integrations that stress build systems across Linux, macOS, Windows, and embedded/video environments. For package nerds, it is also a good example of a protocol whose adoption is visible through formulae, distro packages, badges, and vendor-neutral interoperability work rather than through a single monolithic application. ### Timeline -
