[0051] Explanation of related terms:

[0052] Computing resources: generally refers to the CPU resources, memory resources, hard disk resources and network resources required for the running of computer programs.

[0053] Mesos: An open-source distributed resource management framework, capable of fine-grained resource allocation for distributed clusters. Fine-grained resource allocation refers to the allocation of resources directly according to the actual needs of tasks. This allocation mechanism can greatly improve resource utilization. Mesos is a master / slave structure, in which the master node is used to coordinate all slave nodes and determine the available resources of each node, and then issue resource invitations to the computing framework registered to the master node. The slave node reports its idle resources and task status to the master node, and is responsible for managing various tasks on the node. After the computing framework successfully applies for resources ...

Abstract

The invention provides a video transcoding method, device and system. The method comprises steps of calculating resources required by the to-be-processed video transcoding task when video transcodingtask scheduling is performed; determining a transcoding server of which idle computing resources can meet the computing resources required by the video transcoding task in the cluster; and distributing video transcoding task to the transcoding server according to needs, so that it is achieved that resources are distributed according to needs, the video transcoding task is distributed to the cluster transcoding server more reasonably, the situation that computing resources in the cluster cannot be utilized in a balanced manner is reduced, the computing resource utilization rate of the cluster is improved, and the transcoding efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of video processing, in particular to a video transcoding method, device and system. Background technique [0002] Video transcoding refers to converting a compressed and encoded video stream into another video stream to adapt to different network bandwidths, different terminal processing capabilities, and different user needs. [0003] The current mainstream video transcoding method is distributed transcoding based on Hadoop. Hadoop is an open source distributed processing framework, which can form a distributed cluster of a large number of cheap hardware devices, and store data and run programs on the cluster. In the Hadoop-based distributed transcoding solution, the video is segmented first, and then transcoding tasks corresponding to each video segment are created for the divided video segments, and the transcoding tasks are scheduled to the appropriate transcoding servers in the cluster Run ...
