Problems solved by technology

[0019] In order to solve the problem in the existing algorithm that when the network speed fluctuates greatly, the time for playing the HLS media stream is relatively long or the time for entering the best playback state is relatively long, and provides an HLS-based multimedia self-adaption The playback control method, through the mutual comparison of real-time speed information, average speed information and m3u8 configuration information, we can effectively distinguish the types of network speed changes, and make choices based on the types of network speed changes

Embodiment Construction

[0043] An HLS-based multimedia adaptive playback control method of the present invention, such as figure 1 As shown, by comparing real-time speed information, average speed information, and m3u8 configuration information, we can effectively distinguish the types of network speed changes and make choices based on the types of network speed changes.

[0044] The first step is to obtain the instant speed and average speed of the network

[0045] Specifically, the download information of the most recently downloaded M data packets (the download information includes: the number of downloaded bytes and the time required for downloading) is stored, and the download speed of each of the M data packets is calculated. Store the download information of data packets (N) in the latest period to calculate the average speed.

[0046] For example, if the value of m is 3 and the value of n is 50, the instant speed is calculated from the download information of the latest 3 data packets, and t...

Abstract

The invention discloses a multimedia adaptive play control method based on an HLS, and the method can effectively distinguish the types of network speed changes through the comparison of instant speedinformation, average speed information and m3u8 configuration information, and makes a selection according to the types of the network speed changes.

Description

technical field [0001] The invention relates to an HLS-based multimedia adaptive playback control method, belonging to the field of multimedia adaptive playback control. Background technique [0002] HLS is an HTTP-based streaming media transmission protocol implemented by Apple, which can realize live broadcast and on-demand streaming media, and provide audio and video live broadcast and on-demand solutions for mobile devices. [0003] The HLS protocol converts the media data stream on the server side into different quality, continuous, short-duration media files (MPEG-TS format, generally each small file can be played for 8 seconds, called fragmentation), and the client The end continuously downloads and plays these fragments. [0004] Usually, for the same program, the server provides multiple audio and video streams with different qualities (each quality audio and video stream contains a set of slices, corresponding to a bit rate), and the configuration file in m3u8 for...
