Description

technical field

[0001] The invention relates to the technical field of video communication, in particular to an HLS protocol-based video download method and device thereof. Background technique

[0002] The HLS (Http live streaming) protocol is a streaming media transmission protocol based on the hypertext transfer protocol Http implemented by Apple. The HLS protocol segments the continuous media data with a huge capacity and divides it into a large number of small files for transmission, which caters to the needs of web pages. The file transmission of the server uses a constantly updated lightweight index file to control the download and playback of small media files after division, which can realize live streaming and on-demand streaming. The HLS protocol supports automatic switching of the bit rate on the premise of giving priority to fluency, and is currently widely used by major video websites.

[0003] Through the HLS protocol, the video data is divided into video cli...
