Problems solved by technology

[0003] Since multimedia transcoding processing, especially video transcoding is a very time-consuming and computer-resource-consuming process, the prior art proposes to use multiple transcoding servers to process multiple multimedia transcoding tasks. However, in specific applications , the transcoding server will inevitably have hardware and software failures, which may cause task processing to be blocked; moreover, if a server is blocked by a certain task, the subsequent tasks will often not be able to respond, thus seriously affecting Transcoding efficiency

Abstract

The invention discloses a task processing method of a cluster multimedia transcoding system. The cluster multimedia transcoding system comprises a scheduling server and a plurality of transcoding servers, wherein information of each transcoding server is registered into the scheduling server. The method comprises the following steps that: each transcoding server feeds running state information thereof back to the scheduling server in real time; the scheduling server distributes a trancoding task to a corresponding transcoding server according to the running state information; if the result of the transcoding task processed by the transcoding server is not received in a first preset time, the scheduling server sends a state enquiry request to the transcoding server; and if the response to the state enquiry request made by the transcoding server is not received in a second preset time, the transcoding task is redistributed to other transcoding servers meeting the requirements. The task processing method of the cluster multimedia transcoding system can improve the processing efficiency of transcoding tasks and efficiently save system resources.

Description

technical field [0001] The invention relates to the technical field of distributed processing, in particular to a clustered multimedia transcoding system and a task processing method used on the system. Background technique [0002] With the continuous evolution of the Internet and mobile phone networks, there are more and more platforms for media communication, and the media formats supported by the corresponding communication platforms are also increasing. From mobile phones, to IPTV, and high-definition digital broadcasting, different platforms have content format requirements completely different. In order to enable multimedia data to be transparently exchanged between heterogeneous networks, between different types of access devices, and between different formats, transcoding between multimedia data streams has become a hot research direction at present. Multimedia transcoding. It is to process multimedia data of one standard and format into multimedia data of another ...
