Problems solved by technology

[0003] The relevant processing methods mainly face the following problems: (1) User uploads will have sudden peaks during holidays. In order to ensure the availability of synchronous transcoding services, it is necessary to reserve a large number of resources in the synchronous transcoding cluster. These resources are usually idle , the CPU utilization rate is very low; (2) User uploads and viewing volumes have peaks

Abstract

The invention provides a video transcoding resource scheduling method and device. The video transcoding resource scheduling method comprises the following steps: receiving a first transcoding task; comparing the priority of the first transcoding task with the priority of the transcoding task being executed under the condition that no idle thread exists in a transcoding cluster at present and it isdetermined that a preemption function is started; and under the condition that a second transcoding task of which the priority is lower than that of the first transcoding task exists in the currentlyexecuted transcoding tasks, controlling the server executing the second transcoding task to stop executing the second transcoding task, and sending a request for executing the first transcoding taskto the server stopping executing the second transcoding task. According to the video transcoding resource scheduling method and device disclosed by the invention, the bearing capacity of the peak traffic of the uploading link can be improved, the stability and resource utilization rate of the transcoding cluster are improved, and the server cost is saved.

Description

technical field [0001] The present disclosure relates to the technical field of video transcoding. More specifically, the present disclosure relates to a video transcoding resource scheduling method and device. Background technique [0002] Video transcoding is divided into synchronous (AVC) and asynchronous (HEVC) transcoding. Synchronous transcoding takes less time and has a low compression rate; asynchronous transcoding takes a long time and has a high compression rate. Therefore, all videos are transcoded synchronously when they are uploaded, and high-profile videos are transcoded asynchronously. That is to say, the pre-transcoding and upload transcoding are completed during uploading. After the transcoding is completed, the video is visible to other users, and then the high-profile video is asynchronously transcoded to meet various needs such as downloading and viewing other videos. [0003] The relevant processing methods mainly face the following problems: (1) User...
