In recent years, the live broadcast industry has developed vigorously, and live broadcast platforms have become an indispensable part of people. As a commonly used Web development language, PHP is also widely used in the development of live broadcast platforms. This article will focus on several key technical points in the development of PHP live broadcast function.

1. Audio and video collection and processing

The live broadcast platform needs to obtain the user's video and process it. Audio and video collection and processing is the first step in the development of live broadcast function. The PHP language does not implement the audio and video IO function and needs to be developed with the help of a third-party library. In this regard, FFmpeg is a very important tool. FFmpeg is an open source cross-platform multimedia processing tool. It has flexible audio and video encoding and decoding functions and can be used for audio and video transcoding, editing, collection, packaging and other operations. By integrating FFmpeg, developers can easily implement audio and video capture and processing.

2. Media server construction

In order to realize multi-person online live broadcast, a media server needs to be used to realize the distribution and management of audio and video streams. The media server can transmit video data to the audience and support the distribution and sharing of live streams. Currently, the more popular streaming media servers include Nginx-RTMP, SRS and Wowza. By building a media server, the live broadcast platform can achieve more efficient streaming media transmission and playback.

3. Streaming media protocol

The streaming media protocol refers to the protocol used in the audio and video transmission process. Common streaming media protocols include RTMP, HLS, HDS and HTTP-FLV. RTMP is a streaming media transmission protocol that supports low-latency real-time transmission. HLS (HTTP Live Streaming) is a streaming media protocol launched by Apple that can adapt to multiple resolutions and bit rates, and can be played across terminals. HDS (HTTP Dynamic Streaming) is a streaming media protocol from Adobe. Similar to HLS, it can realize adaptation to multiple resolutions and bit rates. HTTP-FLV is an FLV encapsulation format based on the HTTP protocol, supporting low-latency live broadcast transmission.

4. Streaming and playback

Pushing and playing are essential functions of the live broadcast platform and directly affect the user experience. In the development of PHP live broadcast function, the transmission and viewing of live streams can be easily realized using push streaming and playback technology. Common streaming technologies include RTMP protocol, WebRTC framework, etc., while playback can use technologies such as Flash and H5. At the same time, in order to improve the user's viewing experience, it needs to support multiple resolutions, code rate adaptation, and implement online live broadcast and recording functions.

5. Live interaction

Live interaction is one of the most important functions of the live broadcast platform, which can improve user experience and enhance platform interaction. PHP development can realize live broadcast interaction through barrages, likes, rewards, etc. Barrage is a common way of live broadcast interaction. Users can send barrages to comment or communicate during the live broadcast. Likes and tips are a way to encourage users to actively participate.

6. Security and Stability

In the development of live broadcast platform, security and stability are equally important. Understanding and mastering protection technologies can effectively ensure the normal operation of the live broadcast platform and the security of user information. Common security protection technologies include flow control, frequency limiting, IP banning, etc. At the same time, the stability of the live broadcast platform should be fully considered to ensure the stability, dynamic expansion and load balancing of the server.

To sum up, although the development of PHP live broadcast function requires mastering some professional knowledge and technology, with the development of technology, more and more tools and frameworks can be provided to developers. Paying attention to the updates of development technology can optimize the performance of the live broadcast platform and improve the user experience.
