In the source code APP of the live broadcast platform, there are many and diverse functions, such as the short video function, which helps us obtain information and see what is happening around users around the world or their lives; and the live broadcast function, for example, It provides users with real-time entertainment enjoyment, and also allows some users to become anchors of the source code APP of the live broadcast platform, providing the opportunity to work and make money anytime and anywhere. However, these functions require high-quality real-time video transmission, super interactive experience, or dynamic adaptive functions that can automatically adjust in the face of high load and peak periods. Streaming media technology is the key technology that can help the live broadcast platform source code APP realize these function points. However, to realize streaming media technology, it must be completed in a variety of ways. The DASH protocol we are going to talk about today is a way to complete streaming media technology. , let’s take a closer look at what the DASH protocol is? The role of DASH protocol in the live broadcast platform source code APP and some ways to implement the DASH protocol in the live broadcast platform source code APP.
What is the DASH protocol?
The DASH protocol is also called the dynamic adaptive streaming protocol. The most basic working principle of the DASH protocol is to cut the video content of the live broadcast platform source code APP into several small pieces and store the small pieces on the server respectively, so that the platform can be based on the platform used by the live broadcast platform source code APP users during this period. The equipment performance and network bandwidth are used to adjust the appropriate quality content to download and play to users of the live broadcast platform source code APP, ensuring the stability and continuity of users when using the platform.
The role of DASH protocol in the live broadcast platform source code APP
In addition to the role played by the basic working principle of DASH mentioned in the second paragraph, the DASH protocol also plays many roles in the live broadcast platform source code APP. The following is an explanation of some of the functions of the DASH protocol in the live broadcast platform source code APP:
- Improve video transmission efficiency: DASH protocol can effectively utilize network bandwidth and improve video transmission efficiency. It adjusts the video transmission rate according to the real-time network conditions of the live broadcast platform source code APP user to avoid excessive bandwidth consumption and buffering time, while ensuring the continuity and stability of the video.
- Highly scalable: DASH protocol supports multiple encoding and packaging methods on the server side, and can select the most appropriate video quality and format according to network conditions and client needs. This allows the live broadcast platform source code APP to adjust the video transmission strategy according to the actual situation and provide a better user experience.
- Widely supported by devices: Since DASH is an open standard, many devices and players support this protocol. This includes smartphones, tablets, TVs and desktop computers, etc. This allows users of the live broadcast platform source code APP to not need to specifically purchase or use specific equipment to use the platform normally, which not only facilitates users, but also expands the live broadcast platform source code APP user group.
Part of the way the live broadcast platform source code APP implements the DASH protocol
- Use existing streaming media servers and DASH wrappers: Use streaming media servers, such as NGINX servers, to store and transmit video content; or DASH wrapper tools to package video files into DASH format and generate MPD files to describe media segments and adaptive rules; or the client uses the DASH player to parse the MPD file and select and load appropriate media segments based on network conditions and device performance.
- Use open source DASH libraries: Take advantage of open source DASH libraries, such as dash.js or Shaka Player, which provide a way to simplify the implementation of the DASH protocol; or integrate these libraries into your website or application to make it easier to implement DASH Streaming.
- Use a streaming media framework: Use a streaming media framework, such as FFmpeg, to handle video encoding, encapsulation into DASH format and generate MPD files. Or set up an HTTP server on the server to serve DASH content, while using a client DASH player to play the content.
in conclusion:
Through our careful explanation of the "DASH" protocol of the live broadcast platform source code APP, it is not difficult to see that the DASH protocol is a key part of streaming media technology. It plays an important role in optimizing streaming media transmission and ensures that users of the live broadcast platform source code APP do not have to worry about equipment and Due to the network bandwidth factor, functions such as live broadcast and short video can be used stably and smoothly, which facilitates users and improves the quality of the live broadcast platform source code APP. It is also an indispensable part of the live broadcast platform source code APP.
