The RIST Forum and SipRadius have announced the general availability of libRIST 2.1.2, the first publicly available version of the RIST (Reliable Internet Streaming Transport) Protocol.
Developed by the Video Services Forum and using a standards-based approach, RIST is intended as an open, interoperable solution for low-latency live video over unmanaged networks.
The project consists of a library and sample calling programs implementing the RIST Protocol, which is defined in the Video Services Forum VSF-TR-06 series of specifications. Both RIST Simple Profile (TR-06-1) and forthcoming Main Profile (TR-06-2) are supported. The open source licensing for libRIST provides for free redistribution of source and binaries when accompanied by copyright and disclaimer notices. The project includes command-line applications and even documentation with a suggested test regimen.
Sergio Ammirata, managing director of SipRadius and primary author of the code, said: "libRIST provides a fast-start for developers wishing to incorporate a production quality implementation of the new standard in their own projects. It also provides a platform which they can test or measure their own work against."
Ciro Noronha, RIST Forum president, said: "With the current climate of uncertainty and with many people suddenly seeking to transmit reliable, high-quality video from homes and remote facilities, Internet delivery has become more important than ever. Many of the more advanced features of the protocol, such as encryption, are supported. By providing so much code and functionality up front, we hope to speed the adoption of RIST in general."
The repository is hosted by VideoLan.org at https://code.videolan.org/rist/rist. The libRIST project files include support for Linux, Microsoft Windows and Apple platforms.
