Embodiment Construction

[0031] The transcoding distribution 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 complexity of the transcoding of each video segment Degree, the transcoding performance value of each computing device obtains the first average time required for each computing device to transcode the allocated video segment; determining that the first video segment is on the first computing device Whether the transcoding time of is greater than the first average time; when the judgment result is no, the first video segment is allocated 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 ...

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 present invention relates to the fields 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 moving image compression coding standard), and MPEG-2 (the second-generation moving image compression coding standard), etc. However, different environments often require different encoding techniques, which requires transcoding between different encoding methods. The coding technology itself is very complicated, and single-machine transcoding often takes a relatively long time, so parallel technology may be needed to achieve fast transcoding. In the prior art, parallel transcoding technologies are mainly divided into two types, one is parallel co...
