E-commerce live streaming source code is now a very popular type of live broadcast, because of its live streaming attributes, making e-commerce live streaming source code more easily accepted by the public, and the user coverage area is wider. The competition pressure of e-commerce live streaming source code market like this is relatively large, and the user experience is a major boost to competition, so the e-commerce live broadcasting system attaches great importance to optimization and improves the user experience through system optimization.
E-commerce live streaming source code
1. Domain name resolution optimization
E-commerce live streaming source code is to obtain the server address by resolving the domain name, if the IP has a problem, can not provide services for users, you can change the DNS to ignore the problem IP, do not let users access this IP, these user access will be assigned to other servers. When DNS resolves a new server domain name, the time required is generally about 300ms, and if there is a network problem or high load problem in the resolution process, the resolution time will be extended to the second level.
As the resolution time increases, latency also increases and affects the user experience. In order to optimize the domain name resolution, the e-commerce live streaming source code can cache the results of domain name resolution on the user side and pre-resolve the domain name during playback, so that when watching the live broadcast, there is no need to resolve the domain name, saving the resolution time.
2. Optimization of live broadcasting
There are many factors that affect the user's live viewing experience, such as latency, first screen opening time, codec, etc. If you want to optimize the live viewing experience, you must first understand how the live broadcast is carried out. The basic steps of live broadcast implementation are acquisition, encoding, push streaming, pulling streaming and decoding, and today we focus on the live broadcast steps after the user pulls the stream.
After the user opens the live broadcast room, the e-commerce live broadcast source code will establish a link with the server according to the type of streaming media protocol, and pull the live audio and video data. After the data is pulled, the binary data must first be parsed, the audio and video content required for the live broadcast can be found, and then the operation of unpacking is performed. After unpacking, the encoded audio and video data will be obtained, which requires decoding and recovering the original format of the audio and video data, and then synchronizing the audio and video, and finally playing the synchronized audio and video data to the audience.
If it is to optimize the top screen time, we can start from the steps of parsing binary data, preset the decoder type, and skip the time of the file detection type. The e-commerce live streaming source code can also start from the decoding aspect, narrow the detection range of video data, and cache keyframe data, so that users can quickly obtain keyframes and decode after opening the live broadcast room.
If the delay is optimized, the e-commerce live streaming source code can use the delay catch-up strategy to actively drop packets without affecting the user's viewing after the delay exceeds a certain extent, shortening the live broadcast delay.
