Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of browsers and the technical field of media playing, in particular to a method for playing MSE media source of a browser by SEEK. BACKGROUND

[0002] The browser is a core software widely built-in and used in consumer electronics products, and is also a main software widely used by users to browse information and play media content on the Internet. The MSE is one of the streaming media protocols supported by the browser. Since the content is published in the form of slices, the MSE has great flexibility in content operation. In recent years, with the wide rise of online streaming media content operation, more and more websites and content operators publish online media content and operate advertising information in the form of MSE.

[0003] The SEEK playing function of the streaming media belongs to the basic function of media playing. Due to the particularity of the MSE media protocol, the current SEEK playing function of the MSE media source mostly adopts the SEEK playing mode based on data slices. The SEEK playing mode based on data slices mainly includes the following steps: 1. The user inputs the time point of the SEEK playing in milliseconds; 2. The browser finds the slice containing the time point of the SEEK playing in the list of the media slices of the MSE based on the time point of the SEEK playing; and 3. The browser sends the target data slice to the player, and the player starts playing from the slice. This SEEK playing mode based on data slices has the problem of inaccurate SEEK playing time point, which has a deviation of more than one second from the actual SEEK time point of the user, thereby reducing the viewing experience of the user. SUMMARY

[0004] The present application aims to provide a method for playing MSE media source of a browser by SEEK, so as to solve the problems in the background art.
