Live system source, the development of a live system, the most convenient way is what?
At the beginning, various live broadcast development technologies and services were not perfect, and the huge commercial value of the live broadcast market had not been explored. In the initial stage of the birth of the live broadcast platform, there was no customized source development service of the live broadcast system in the market. Want to develop a set of live broadcast system source, you need to form a technical team.
So, what technology does live broadcast system source development need in the end?

1. Audio and video collection

Acquisition is the first link in the playback process. The iOS system is relatively simple because there are few kinds of software and hardware and the hardware adaptation is good.
Android is different. There are so many hardware models out there that it’s hard to fit all of them in one library.

2. Audio and video processing

Beauty system is now a necessary live broadcast system. Not only beauty, but also many other video processes such as blur effects and watermarks. At present, the well-known library of GPUImage on iOS provides rich pre-processing effects. You can also write your own algorithm based on this library to achieve richer effects.
Android also has a port of the GPUImage library, called Android-gpuImage.

3. Audio and video coding

There are two main coding challenges: dealing with hardware compatibility issues and finding a balance between high FPS, low bitrate and sound quality.

IOS hardware compatibility is good, you can directly use hard programming. And Android hard support is much more difficult, need to support a variety of hardware models, is generally the use of software.

4. Push flow and transmission

Transmission involves many ends: from the host end to the server end; From the receiving server to the edge node; And then from the edge node to the spectator end.
Push flow end and distribute end theory needs to support concurrent users should be level, but generated content push flow end in only a few, and consumption content end play end is not an order of magnitude, but their demands to push flow stability and speed is much higher than play the end, it involves all can see live broadcast end, and how the live end quality.

5. Real-time audio and video transcoding

In order to adapt the streams uploaded by anchors to different protocols on different platforms, some stream processing work needs to be done on the server side, such as transcoding into different formats and supporting different protocols, such as RTMP, HLS and FLV, and transcoding to multi-channel streams to adapt to different network conditions and terminal devices with different resolutions.

6. Decode and render

Decoding and rendering, also known as audio and video playback, currently have good playback compatibility on iOS and can be used under acceptable delay conditions
The HLS protocol is the best choice. Android hardware decoding has compatibility issues as well as encoding.

7. Live broadcast scenarioization solution

Scenarioization refers to the specific solution composed of unique functions provided for different vertical broadcast characteristics.
Not only is this a huge expense, but it also takes a long time to develop.
Nowadays, due to the huge potential of the live broadcast market, all kinds of capital are pouring in, which reduces the cost of the live broadcast development business to a certain extent. More and more live broadcast system development service providers can directly provide the source code of the live broadcast system with perfect functions.
You can have no technical team and do not need to do development. Livestream development service providers sell the source code of finished products, and they will help you build quickly. After purchase, you can go online and operate, saving time and cost.
When you don’t have a technical team, but want to do different functions, you can also choose to buy the source code of the live broadcast system. The service provider can develop the source code first and then build it according to your needs, which will be relatively expensive.
So no matter which one you choose, the source code of the live broadcast system can make you get a live broadcast platform of your own, and achieve rapid establishment and operation.
