Abstract

The embodiment of the invention relates to an audio and video playing method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining slice addresses of a plurality of resolutions of an audio and video according to an audio and video on demand request; constructing an M3U8 playlist according to the slice address; matching a target address of a corresponding slice from the M3U8 playlist in real time according to the change information of the network state; and obtaining a slice corresponding to the target address to play the audio and video, so the resolution can be automatically switched according to the network state, and slice addresses with different resolutions do not need to be re-requested from the server, so that a system player does not need to be restarted if resolution switching needs to be carried out in an audio and video playing process, a black screen is prevented from appearing in a current playing interface, a smooth playing effect is achieved, and the audio and video watching experience of a user is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of audio and video processing, and in particular, to an audio and video playing method, device, electronic equipment, and storage medium. Background technique [0002] Dynamic code rate adaptive technology (HTTP Live Streaming, HLS) is a hypertext transfer protocol (HTTP)-based media streaming protocol implemented by Apple, which can be downloaded through HTTP by cutting the entire stream into small ones. media files, and then provide a supporting media list file, and provide the media list file to the client, so that the client pulls these media files sequentially to play, so as to achieve the effect that it seems to be playing a stream. The HLS protocol is mainly used for data transmission of M3U files (M3U8) format files in UTF-8 encoding format. The addresses of M3U8 format files are usually stored in lists, such as media playlists (Media Playlist) and master playlists (MasterPlaylist), where...
