Live broadcast stream interaction control method and corresponding device, equipment and medium thereof

Abstract

The invention relates to the field of network live broadcast, and discloses a live broadcast stream interaction control method and a corresponding device, equipment and medium thereof. The method comprises the following steps: establishing a data communication link from a stream pushing device to a stream broadcasting device through a server relay, wherein the data communication link is used for pushing a live stream generated by the stream pushing device to the stream broadcasting device; applying preset link control information to simulate and control the network transmission performance of the data communication link so as to control the live broadcast stream reaching the audio and video quality of the stream broadcasting device; and receiving the live broadcast stream generated by the stream pushing device through the data communication link, and forwarding the live broadcast stream to the stream broadcasting device for playing and displaying. According to the invention, simulation and reproduction of a real production environment network can be realized for transmission of the live broadcast stream, and online audio and video quality problems can be tracked conveniently or the audio and video quality is limited as required.

Description

technical field [0001] The present application relates to the field of network live broadcasting, and in particular to a method and device for interactive control of live streaming, as well as corresponding electronic equipment and non-volatile storage media. Background technique [0002] In audio and video interaction and webcasting scenarios, it is often necessary to use network damage equipment in the laboratory to simulate various network environments, including normal network and weak network conditions. The main network factors that need to be simulated are packet loss rate, bandwidth, delay, etc. , and then evaluate the audio and video quality under various transmission and encoding strategies through a simulated network environment. Throughout the process, there were two outstanding issues: [0003] 1) The network conditions need to be manually modified, and the evaluation results need to be collected by means of manual screen recording, photography, subjective audi...

AI Technical Summary

Problems solved by technology

[0003] 1) The network conditions need to be manually modified, and the evaluation results need to be collected by means of manual screen recording, photography, subjective audio-visual, etc. The sorting of the results is time-consuming, error-prone and highly subjective

[0004] 2) The simulation of the network in the laboratory is mainly realized through the network damage tester, while the existing network damage tester can only use a few modes (such as fixed, random, burst, sinusoidal, etc.) to damage the network conditions. ) to simulate, this one-size-fits-all method greatly simplifies the complexity and timeliness of the network, which is far from the network situation encountered in the actual production environment, so the evaluation of audio and video codec and transmission algorithm strategies is not comprehensive enough , it is easy to obtain good results in the laboratory through test-oriented practices, but it is impossible to obtain good results in the AB test of the actual production environment

[0006] It can be seen that the simulation technology of the network environment required for audio and video interaction in the process of live broadcasting in the prior art is still insufficient, resulting in low efficiency of related tests, and there should be room for improvement
