Simple Realtime Server (SRS) is a real-time video server that supports various protocols, such as RTMP, WebRTC, HLS, HTTP-FLV, SRT, and MPEG-DASH. It acts as a media gateway, converting between RTMP, SRT, and WebRTC. SRS has several use cases, including as an origin cluster, for virtual live-streaming with SRS Cloud, with the SRS Player WordPress plugin, for Unity developers, in the broadcast industry, for AI video and audio processing, and for cutting live-streaming expenses. SRS is compatible with various open-source technologies and has a global community on Discord.

While Open Broadcaster Software (OBS) is a widely used solution for live-streaming to YouTube via RTMP or RTMPS, there is an alternative approach that leverages a web browser.

This method involves streaming your camera using WebRTC within a webpage, then employing Simple Realtime Server (SRS) to convert WebRTC to RTMP, and using FFmpeg to publish the RTMP stream to YouTube. For those who prefer RTMPS, FFmpeg can be utilized to extract the stream from SRS via RTMP, transcode it to RTMPS, and subsequently publish it to YouTube.

As a CA(Certificate Authority), Let's Encrypt provides free and automatic TLS/SSL certificates, which enables encrypted HTTPS for SRS Droplet. It's very easy to use, only by 1-Click.

HTTPS is required for publishing streams using WebRTC, and it improves security. If you want to support the video streaming in any HTTPS website, such as a WordPress website, you must use HLS/FLV/WebRTC with HTTPS, or it will fail for security reasons.

Note that SRS droplet only supports a single domain name, which makes the problem simple. It is easy to use.

In this tutorial, you will learn how to configure the HTTPS for SRS droplets, and your certificate will be renewed automatically.

Streaming video is very popular in a variety of industries, and there are many tutorials for building a media server, using SRS or NGINX-RTMP that host stream does not rely on other service providers. But if we want to build a online video streaming service, it's much more than only a media server:

  1. Authentication: Because the server is on the public internet with a public IPv4 address, how to do authentication? How to block all users except they have the correct token?
  2. Multiple Protocols: Rather than publishing RTMP using OBS, you might need WebRTC or H5 to publish live streaming, for it's easy to use. You might also use SRT with some broadcasting devices. How to convert RTMP/WebRTC/SRT to HLS?
  3. Restreaming and DVR: To help you boost engagement and reach, you could connect other service providers to restream, such as YouTube, Twitch and Facebook. Well, DVR allows you to continue engagement after live events have ended, generating revenue via VoD(on-demand video).

Literally it's not just a media server, and seems a bit complicated, right? Yep and No!

  • Yep! Building a video streaming service is something really difficult, not easy. It requires video streaming engineering, also backend service technology like Nodejs or Go, and frontend skills to build a mgmt and homepage.
  • No! Rather than build all from scratch, we could build a video streaming service based on some open source solution such as SRS Cloud, and lightweight cloud service such as DigitalOcean or TencentCloud, it's really simple to build your video streaming service.

In this tutorial, you will learn how to set-up a video streaming service, supports publishing by browser without a plugin that is converting WebRTC to HLS, to deliver low latency (about 300ms) video streaming using SRT, and to secure the service by authentication. Furthermore, this solution is open source and very easy to get it done, via even 1-Click.
