SRS 6.0 supports HEVC(H.265), for RTMP, HTTP-FLV, HTTP-TS, HLS, MPEG-DASH, WebRTC(Safari), DVR FLV, DVR MP4 and WordPress SrsPlayer, etc.
Generally, H.265 is 50% off than H.264, so you only need to pay 50% bills if H.265.

State Threads is an application library which provides a foundation for writing fast and highly scalable Internet Applications on UNIX-like platforms. It combines the simplicity of the multithreaded programming paradigm, in which one thread supports each simultaneous connection, with the performance and scalability of an event-driven state machine architecture.
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.
In many networks, UDP is not available for WebRTC, so TCP is very important to make it highly reliable. SRS supports directly TCP transport for WebRTC, not TURN, which introduce a complex network layer and system. It also makes the LoadBalancer possible to forward TCP packets, because TCP is more stable than UDP for LoadBalancer.
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.
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.
