Video transcoding method, video transcoding apparatus and server

Abstract

The invention discloses a video transcoding method, a video transcoding apparatus and a server, and belongs to the network technology field. The method comprises determining the transcoding priority of each video clip according to the video statistical information in the first time quantum; determining video clips to be transcoded in the second time quantum according to the transcoding priority of each video clip, wherein the first time quantum is the prior time quantum of the second time quantum; and performing video transcoding to the video clips to be transcoded in the second time quantum. The method provided by the invention can determine the transcoding priority of each video clip through the video statistical information in the prior time quantum and use the practical playing situation to predict which one among video clips is most likely to be requested by a user in the current time quantum so as to determine the video clips which should be transcoded in the current time quantum according to the transcoding priority to avoid waste of calculation resource and storage resource because of transcoding of a large number of video clips.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a video transcoding method, device and server. Background technique [0002] With the development of network technology, dynamic adaptive video transmission has become one of the most popular video transmission technologies on the Internet. [0003] In dynamic adaptive video transmission, in order to meet the needs of users for video clips, video service providers need to transcode each released video into a set of versions with different bit rates, that is, to provide multiple video clips for the same video clip. Versions with different bit rates, so that users can download corresponding versions of videos according to their own network conditions, so as to achieve the purpose of video transmission. However, since a fixed transcoding bit rate has been set during transcoding, the user can only select a video version from limited bit rates, which cannot effectively adapt...

AI Technical Summary

Problems solved by technology

However, since a fixed transcoding bit rate has been set during transcoding, users can only choose video versions from limited bit rates, which cannot effectively adapt to changing network conditions

[0004] In order to solve the above problems, video service providers will increase the number of video versions provided, and with the increase in the number of uploaded videos and the number of versions, the computing resources consumed for transcoding will increase greatly

Moreover, since the popularity distribution of video clips is obviously biased towards heavy-tailed distributions, for example, because existing video sharing services are based on UGC (User-generated content), a large part of video clips will not be watched, if Transcoding these video clips is a huge waste of computing and storage resources
