Embodiment Construction

[0046] The present invention will be further described below in conjunction with the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0047] Game live broadcast platform

[0048] The Live Game Video Streaming Platform is a video platform that uses game videos uploaded by game players in real time as the video source to provide viewers with real-time game video services. The game live broadcast platform is mainly responsible for online transcoding of real-time video streams uploaded by game players and distributing the transcoded video streams to viewers.

[0049] Crowdsourced Live Game VideoStreaming Service Provider is the operator of the game live broadcast platform. With the help of cloud computing, cloud storage and other related technologies, the game video stream uploaded by game players is transcoded in real time, and the transcoded video stream is distributed to the audience.

Abstract

The invention discloses a video stream transcoding and distributing method applied to a live game video streaming platform. The video stream transcoding and distributing method comprises the following steps: S1, dividing a running period of the live game video streaming platform into a plurality of time periods; S2, acquiring information uploaded by anchors in real time through a central control unit at the start of the time periods; S3, solving an optimal solution by the central control unit with a Lyapunov optimization method based on currently-collected information to use the optimal solution as a decision result, wherein the decision result includes decisions of a video stream transcoding decision, a video stream distribution decision and a user code rate selection decision; and S4, making a video stream transcoding decision for online game anchors based on the acquired decision result, and making a video stream distribution decision and a code rate selection decision for online audience.

Description

Technical field [0001] The invention relates to the field of multimedia network and cloud computing resource management, and more specifically, to a video stream transcoding and distribution method applied to a game live broadcast platform. Background technique [0002] In recent years, with the mobile Internet revolution, the popularization of smart terminal devices and the rapid development of the game industry, game live broadcast, an emerging video entertainment method, has flourished. Following the great success of the Twitch.tv game live broadcast platform in foreign markets, a large number of game live broadcast platforms such as Douyu.tv, Huya Live, and Dragon Ball Live have emerged in China. The game live broadcast platform uses the real-time video stream uploaded by the majority of game players as the video source to provide game players with real-time video stream transcoding services and real-time video stream distribution services. Through the real-time video stream...
