If you use PHP to develop live broadcast applications, you can use an existing live broadcast server, such as Nginx-rtmp-module.

2. Media Encoder

Currently, there are many mature streaming clients on the market, such as OBS, XSplit, etc. If you want to develop your own streaming client, you can use the FFPlay library.

4. Player

The player is an indispensable part of the live broadcast application. In your live broadcast application, you need to provide users with a good playback experience, including clear video and smooth audio. Currently, there are many mature players on the market, such as JWPlayer, FlowPlayer, VideoJS, etc. You can choose to use one of them or develop your own player according to your own needs.
