Embodiment Construction

[0089] Since the method of judging the size of the node load based on the length of the data block queue in the node will reduce the efficiency of multimedia files being transcoded in the cloud computing platform, the embodiments of the present invention no longer simply use the data block queue The length of the data block is used as the judgment basis, but the length of time required for the processing of each data block in the data block queue is used as the judgment basis. Utilize the method in each embodiment of the present invention, can avoid to use the node that although data block queue is relatively short, but needs to wait for a long time, multimedia file is processed, thereby effectively improved multimedia file in the cloud computing platform transcoding efficiency.

[0090] The methods for processing multimedia files described in the various embodiments of the present invention can be applied to cloud computing platforms or various cluster systems. The multimedi...

Abstract

The embodiment of the invention provides a method, a device and a system for processing a multimedia file. The method for processing the multimedia file comprises the following steps: obtaining estimated remaining time of a data block queue according to the estimated remaining time of at least one data block among the data block queue of nodes in a group; obtaining the load of the nodes according to the estimated remaining time of the data block queue, wherein the estimated remaining time of the data block queue is obtained according to the data size of the data block and the estimated processing rate of the multimedia file which contains the data block, and the estimated processing rate of the multimedia file corresponds to the type of the multimedia file; judging the load of the nodes according to the required time for completing the processing of the current task in the data block queue. The method is more reasonable, and can avoid taking the node which has a shorter data block queue but requires a longer processing time as a light load node, so as to effectively reduce the unnecessary waiting time and effectively increase the transcoding efficiency of the multimedia file.

Description

technical field [0001] The embodiments of the present invention relate to computer technology, and in particular to a multimedia file processing method, device and system. Background technique [0002] With the development of computer technology and multimedia technology, the file formats of multimedia files such as audio and video are also increasingly diversified. By transcoding the multimedia file, the file format of the multimedia file can be converted between multiple file formats to meet different playback requirements. [0003] When the file format of the multimedia file needs to be converted into the target format, transcoding is performed on the entire multimedia file. It takes a long time and consumes more resources. In order to improve transcoding efficiency, multimedia files can be divided into several smaller data blocks, and multiple nodes in the cloud computing (cloud computing) platform are used to transcode these data blocks respectively, and then each tra...
