FAQs
/
What is SRT streaming?
SRT streaming uses the Secure Reliable Transport protocol, an open-source technology developed by the SRT Alliance. It’s designed to send high-quality video and audio securely over unpredictable networks. Encoders using SRT can deliver smooth, reliable live video streams with minimal packet loss, making it ideal for professional broadcasting and real-time video delivery.
/
Is SRT faster than RTMP?
Yes, SRT is generally faster and more reliable than RTMP, especially over unstable networks. While RTMP often introduces seconds of delay, SRT can achieve ultra-low latency streaming within a few hundred milliseconds. It also includes error correction and encryption, making it more secure and resilient for modern live-streaming environments.

What codecs does SRT support?
SRT is codec-agnostic, meaning it can transport any audio or video codec without restriction. Whether you use H.264, H.265, VP9, AV1, AAC, or Opus, SRT simply carries the encoded data from one endpoint to another. This flexibility makes it easy to integrate SRT into existing workflows and adapt to different quality or bandwidth requirements.
