Streaming protocol

Introduction

LiveSteam Pro enables the use of both RTMPS and SRT protocols to stream audio, video, and data over the Internet. Both open-source protocols have different strengths when it comes to the optimization of video streaming.

RTMPS

RTMP stands for Real-Time Messaging Protocol. RTMPS is a variation that uses secure SSL connections to minimize the risk of cloud-based streaming. It works well for town halls and one-to-many broadcasts. It maintains a persistent TCP connection between the video player and the server and ensures a reliable stream to the end-user.

Ingest server authentication

For increased security, RTMPS streaming will have username and password authentication enabled by default for the ingest server. You can copy and paste the credentials into the supported encoders.

If the encoder does not support ingest authentication, or if you want to stream from a third-party application like virtual meeting rooms, you can disable this option. The incoming stream will then be accepted without a username and password.

SRT

SRT, which stands for Secure Reliable Transport, is specifically developed for streaming with low latency over networks that may be weaker or unpredictable. Like RMTPS, SRT is a persistent protocol that efficiently utilizes bandwidth. Additionally, SRT serves as a secure streaming protocol, simplifies firewall traversal, and ensures high-quality video delivery even over challenging network conditions.
