SRT (Secure Reliable Transport Protocol) is a new transport protocol that solves the issue of low-quality video under noisy, poor public internet networks. The goal behind its implementation is to optimize video transport over unpredictable networks by minimizing lost packets and bandwidth fluctuations. In short, SRT offers high-quality and low latency video streaming with greater security.
None of the mainstream services like Twitch, Youtube, Facebook supports SRT protocol at the moment. The best way to stream SRT to those platforms is by sending the SRT to Castr, and then using Castr to multistream to those social platforms simultaneously.
RTMP is currently the most widely used protocol for video live streaming, It's also used as an ingest protocol to live stream to platforms like Facebook, Youtube, Twitch, etc. However, SRT stream is 12 times faster than an RTMP stream and has stable delivery under poor networks.
