Distributed video transcoding method and related device

Abstract

The invention provides a distributed video transcoding method and a related device. The method comprises the steps of controlling a video uploading terminal through a transcoding control server, achieving a network-based distributed transcoding system, distributing transcoding tasks through a network, and achieving controlled distributed transcoding at the video uploading terminal. The transcoding control server manages and schedules transcoding tasks of all video uploading terminals, so that repeated utilization and balance of transcoding calculation performance are realized under the condition of unbalanced hardware configuration, and the purpose of efficient and balanced large-scale video transcoding is achieved. Occupation conditions of a CPU, a hard disk and content are monitored, and high-priority tasks such as user operation are protected. Through automatic re-scanning and repeated content elimination, repeated transcoding during transcoding task recovery is avoided; and when the network is interrupted, an independent transcoding task execution mode is adopted, thereby ensuring that the transcoding process is not interrupted and uploading is automatically recovered when the network is recovered. The distributed video transcoding method achieves better system adaptability and stability through exception handling.

Description

Technical field [0001] The present invention relates to the field of video data codec, and more particularly to distributed video transcoding methods and related devices. Background technique [0002] Video transcoding means converting video code streams that have been compressed into another video stream to accommodate different network bandwidth, different terminal processing capabilities, and different user needs. The video transfer is essentially a process of first decoding, then encoded, so the video code stream before and after conversion can follow the same video coding standard, or the different video coding standards can also follow. [0003] Video transcoding tasks typically consume system computing resources, including the CPU processing capabilities and hard disk I / O bandwidth, therefore, single terminals are often not high. Therefore, there is now an urgent need for a high efficiency video transfer method. Inventive content [0004] In view of this, the present in...
