Adaptive low-latency streaming media playing software for live webcast scenario

Abstract

The invention relates to the field of computer software, and in particular to media playback. The adaptive low-latency streaming media playing software for live webcast scenario comprises the following steps of: observing network jitter through a network monitoring module to determine a frame loss window; transmitting the information of the frame loss window to an audio frame loss module through the network monitoring module; determining the frame loss by the audio frame loss module according to the information of the frame loss window; sending the frame loss information to a video packet lossmodule through the audio frame loss module; performing video packet loss by the video packet loss module; and decoding the video. Through the design, the invention adaptively determines the chasing frame threshold range according to the network fluctuation condition of the player, and balances the network lagging as much as possible while ensuring low delay; the audio playback performs frame lossprocessing according to the chasing frame threshold range, and the video synchronization is performed with packet loss before decoding, thereby avoiding the lagging phenomenon of low-latency chasingframes that may occur due to slow video decoding.

Description

technical field [0001] The present invention relates to the field of computer software, in particular to media playing. Background technique [0002] Live broadcast is a form of real-time and interactive content dissemination on the Internet. In the live broadcast scene, because the real-time stream is played, there will be problems of delay and freeze at the same time. The freeze and delay affect each other and contradict each other. The reason is due to the jitter on the network line during the playback of the real-time stream Usually, the playback delay can be solved by chasing frames, but this will cause obvious lag when the network conditions are not good, which not only affects the user experience, but also may increase the delay of the playback end. Contents of the invention [0003] The purpose of the present invention is to provide an adaptive low-latency streaming media playback software suitable for network live broadcasting, so as to solve at least one of the ...
