Embodiment Construction

[0030] The transcoding allocation method in the embodiment of the present invention is to obtain the transcoding complexity of each video segment to be transcoded and the transcoding performance value of each computing device constituting the cloud platform; according to the transcoding complexity of each video segment According to the transcoding performance value of each computing device, obtain the first average time required by each computing device to transcode the assigned video clips respectively; Whether the transcoding time is greater than the first average time; if the judgment result is no, assign the first video segment to the first computing device for transcoding. According to the obtained transcoding complexity of each video segment and the transcoding performance value of each computing device, the first average time required for each computing device to transcode the allocated video segment is obtained, when a video segment is in When the transcoding time on a...

Abstract

The invention discloses a method for transocding distribution based on a cloud platform, and the method for transcoding distribution is used for improving transcoding efficiency. The method for transcoding distribution comprises the following steps: obtaining transcoding complexity of each video clip to be transcoded and transcoding performance values of calculating equipment which form the cloud platform; according to the transcoding complexity of each video clip to be transcoded and the transcoding performance values of the calculating equipment, obtaining a needed first average time of each one of the calculating equipment carrying out transcoding for the video clip distributed for the each one of the calculating equipment; judging whether needed transcoding time of a first calculating device for transcodiing a first video clip is larger than the first average time; if a result is no, distributing the first video clip to the first calculating device to carry out transcoding. The invention further discloses a device used for achieving the method for transcoding distribution and a method and device for transcoding.

Description

technical field [0001] The invention relates to the field of video coding and distributed computing, in particular to a transcoding distribution method and device, and a transcoding method and equipment. Background technique [0002] With the development of video coding technology, more and more coding methods and standards have emerged, such as H.264 (highly compressed digital video codec standard), MPEG-4 (fourth generation motion picture compression coding standard) and MPEG-2 (second-generation moving picture compression coding standard) and the like. Different environments often require different encoding technologies, which requires transcoding between different encoding methods. The encoding technology itself is very complicated, and it takes a long time to transcode on a single machine, so parallel technology may be required to achieve fast transcoding. In the prior art, parallel transcoding technologies are mainly divided into two types, one is multi-core-based pa...
