Problems solved by technology

Although there is no large playback delay in the existing technology, when there is network jitter, it is easy to cause too little cached data and face the risk of freezing; in addition, the media bit rate is the average bit rate of the video stream. For video data with a large average ratio (peak bit rate / average value), the actual downloaded media stream may account for a very large proportion of moving images in a certain period of time, and its actual bit rate is significantly higher than the average bit rate. At this time, it will also face the risk of freezing

Abstract

The embodiment of the present invention provides a method and a terminal for playing streaming media online. The method includes: the terminal obtains and caches video stream data from a streaming media server, and updates the playback duration of the cached data; the terminal calculates the current download bandwidth and the actual video stream data. bit rate and obtain the minimum cache data playback duration; determine whether the current cached data meets the minimum cache data playback duration and the playback conditions; if the above conditions are met at the same time, start playing the video. The embodiments of the present invention take full account of different network conditions, and apply different start playback conditions according to different network qualities, reduce the risk of freezing after video playback, and finally achieve smooth video playback in different network environments.

Description

technical field [0001] The invention relates to the field of multimedia technology, in particular to a method and terminal for playing streaming media online. Background technique [0002] With the continuous improvement of the network level of social life, streaming media has become an indispensable means in people's daily life, work and entertainment. Using streaming media technology, users can be provided with continuous audio and video streams to meet the needs of users to watch dynamic audio and video online. [0003] The HTTP adaptive video streaming technology has the advantages of low requirements on streaming media servers and terminals, and the smoothness of playback under different networks through multiple bit rates, so it has occupied a mainstream position in the application of mobile Internet video services in recent years. [0004] In HTTP adaptive video streaming technology, a video source is encoded by an encoder into multiple videos with different video bi...
