HLS (HTTP Live Streaming) streaming media playing method and system

Abstract

The invention provides an HLS (HTTP Live Streaming) streaming media playing method and system. The method comprises the following steps: acquiring an M3U8 index file of an HLS streaming media, and selecting the index information corresponding to a replacement stream with the lowest code rate as a first current playlist according to index information in the M3U8 index file; according to address information of a to-be-processed TS fragment in the first current playlist, acquiring an audio and video original stream of the to-be-processed TS fragment, and storing the audio and video original stream into a cache queue; calculating the real-time bandwidth of a network according to the download time and the data volume size of the audio and video original stream; and according to the index information of the M3U8 index file, selecting a replacement stream with a larger code rate from the replacement streams with the code rate less than the real-time bandwidth, and taking the corresponding index information as a second current playlist to replace the first current playlist. The HLS streaming media playing method provided by the invention can still guarantee the continuity of HLS streamingmedia playing and reduce the situation of playing jamming when the network environment is very poor.

Description

technical field [0001] The invention relates to the field of network streaming media playback, in particular to a playback processing method and system for HLS streaming media when the network is unstable. Background technique [0002] The transmission of digital video has gone through cable TV network and IPTV, and now it has entered the era of Internet TV. Traditional cable TV and IPTV transmit multimedia data through dedicated channels, which can ensure that the data is smooth and punctual. However, multimedia data based on the Internet or mobile Internet does not have a dedicated transmission channel. The data is transmitted on the public network, and the probability of network congestion during peak hours is high. The stability of the bandwidth of the transmission channel cannot be guaranteed, especially in the case of a mobile network, the network stability is poor, and the probability of jitter is high, resulting in a sharp change in the network bandwidth. For video ...
