Problems solved by technology
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.

Embodiment Construction
[0045] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0046] like figure 1 and figure 2 As shown, an adaptive low-latency streaming media playback method suitable for network live broadcasting scenarios includes the following steps: step 1, observe network jitter through the network monitoring module, and determine the frame loss window; step 2, use the network monitoring module to The information of the frame loss window is sent to the audio frame loss module; Step 3, through the audio frame loss module, it is judged whether frame loss is needed according to the information of the frame loss window; Step 4, the frame loss information is sent to the video packet loss module through the audio frame loss module ; Step five, video packet loss through the video packet loss module; Step six, video decoding. Observe the network jitter through the network monitoring module, determine the frame loss...

The invention relates to the field of computer software, in particular to media playing. An adaptive low-latency streaming media playback method suitable for network live broadcasting scenarios, comprising the following steps: observing network jitter through a network monitoring module to determine a frame loss window; sending information about the frame loss window to an audio loss Frame module; judge frame loss through audio frame loss module according to frame loss window information; send frame loss information to video packet loss module through audio frame loss module; video packet loss through video packet loss module; video decoding. Through this design, the present invention can adaptively determine the frame chasing threshold range according to the network fluctuations of the player, and try to balance the network freeze while ensuring low delay; audio playback performs frame loss processing according to the frame chasing threshold range, and video synchronization is in Packet loss before decoding, to avoid low-latency chasing frames 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 method suitable for network live broadcasting scenarios, so as to solve at least one...
