Problems solved by technology
Video transcoding technology, as a necessary part of video application system, has been paid more and more attention by people. For this reason, people have created the concept of transcoding factory to describe the system for offline transcoding of massive videos. Some use workflow Some use distributed systems, some use GPU (Graphic Processing Unit, graphics processing unit) transcoding clusters, etc. These systems often consume huge costs, the degree of homogeneity of computing units is high, and the computing units are closely spaced. Coupling, limited scalability and maintainability

Embodiment Construction
[0016] Exemplary embodiments will be described more fully with reference to the accompanying drawings to make the aspects, other aspects, features, and advantages of the inventive concept clear. However, the exemplary embodiments may be embodied in many different forms, and should not be construed as being limited to the exemplary embodiments set forth herein. Rather, the exemplary embodiments are provided so that this disclosure will be thorough and complete, and fully convey the scope of the application to those skilled in the art.
[0017] In the embodiment of the present invention, the video data is divided to obtain a transcoding task queue; the transcoding task is broadcast to the transcoding subsystem that has been registered in the cloud platform; the transcoding subsystem evaluates its own load and decides whether to respond; task The module selects the subsystem that completes the transcoding task according to the optimal strategy, and assigns the transcoding task to th...

The invention provides a video transcoding method and device based on a cloud platform. The method comprises following steps of segmenting video data, thus obtaining a transcoding task queue; broadcasting transcoding tasks to transcoding subsystems; waiting for response, wherein the transcoding subsystems are registered on the cloud platform; estimating own states by the transcoding subsystems and determining whether to respond or not after the transcoding tasks are received; selecting the transcoding subsystems according to an optimization strategy if there is one or more responding transcoding subsystems; distributing the transcoding tasks to the selected transcoding subsystems; transcoding by the selected transcoding subsystems; continuing to poll the transcoding task queue; initiating broadcast of a next round; waiting until waiting is overtime if there is no responding transcoding subsystem; repeatedly broadcasting the transcoding task queue until the transcoding tasks are finished; and then forming a transcoded complete video.
Description
Technical field [0001] The present invention relates to the field of video transcoding, and more specifically, to a video transcoding method and device based on a cloud platform. Background technique [0002] With the continuous development of the Internet and multimedia technologies, video, as the main carrier of information, is being applied to various devices and fields. As a necessary component of video application systems, video transcoding technology has attracted more and more attention. For this reason, people created the concept of transcoding factory to describe systems that specialize in offline transcoding of massive videos, and some use workflows. Some use distributed systems, some use GPU (Graphic Processing Unit, graphics processing unit) transcoding clusters, etc. These systems often consume huge costs, the degree of homogeneity of computing units is high, and the computing units are tightly distributed. Coupling, scalability and maintainability are limited. Sum...
