What is MPEG-DASH(Dynamic Adaptive Streaming over HTTP)? Because Apple HLS is not good enough, so some guys wanted to fix it and created an even worse protocol, named DASH or MPEG-DASH.

Well, it's just a joke for any new technology, especially when it's new and there are some issues. However, it's really true for DASH today, at 2022.11, because we're really suffering while maintaining it.

But, DASH is becoming more and more popular protocol for live streaming, and we believe that all issues will be fixed in not very far future, so let's take a look about these issues.

Coroutines are core technologies for modern servers that significantly simplify the logic and facilitate maintenance. SRT is a new streaming protocol that is gradually taking over from RTMP. With its own I/O framework, SRT can mature only by becoming coroutine-native, the first and crucial step of SRS 5.0.

This decade has seen rapid development in audio and video technology, from interactive entertainment and live e-commerce to online conferences and online education, with the recent rise of the metaverse, audio and video being one of the fundamental capabilities.

Starting from the live streaming with video chat scenario, we can understand the technologies involved in internet audio and video. By delving deeper into the relevant technical points of audio and video, we can build a complete audio and video technology system and quickly apply it to online businesses.

When our business workloads exceed streaming-server capacity, we have to balance those workloads. Normally, the problem can be solved by clustering. Clustering is not the only way to solve this problem, though. Sometimes the concept of Load Balancing can be linked to many emerging terms such as Service Discovery, but a LoadBalancer in cloud service is an indispensable requirement for solving the problem. In short, this problem is very complicated, and many people ask me about this frequently. Here I’m going to systematically discuss this issue.

aaPanel is a simple website and server management tool. It is similar to cpanel.net, while aaPanel is free, open source and easy to develop plugins for media servers.

In this tutorial, you will learn how to deploy a live streaming media server, using aaPanel. If you have websites deployed with aaPanel, it's also possible to deploy an extra media server to power your website with live streaming service, for example, to enable live streaming feature for your WordPress website.

After you have set up your own live streaming server through the SRS Droplet you received multiple links to publish your stream. You can use the build in players or use the links in VLC for example for the various sources.

But what if you would like to embed your HTTP-FLV, HLS or WebRTC stream straight into your WordPress site?

In this tutorial, I will show you how you set up your WordPress and SRS Player plugin to stream right through your website for viewers to watch.

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, or OBS WHIP Server 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).
4. Transcoding: Optimizes streaming for viewers with different internet speeds and devices, reduces bandwidth usage, and saves costs.
5. Virtual Live Events: Create seamless and engaging live streaming experiences using pre-recorded content for various applications, such as e-commerce, education, and online speeches.
6. IP Camera Streaming: Effortlessly stream your RTSP IP camera to popular platforms like YouTube, Twitch, or Facebook.

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 Stack, and lightweight cloud service such as DigitalOcean or AWS, 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.
