Problems solved by technology

[0003] In the prior art, when transcoding, the same video file is performed by a transcoding machine, but the defect of this transcoding method is also obvious. When the video file is very large, the time required for transcoding is It will become very long, often delaying the release of new videos due to transcoding

Embodiment Construction

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] figure 1 The flow of the preferred embodiment of the cloud transcoding method for video files of the present invention is shown. See figure 1 , the following is a detailed description of the implementation steps of the cloud transcoding method for video files in this embodiment.

[0026] Step S10: Divide the video file into multiple video segments.

[0027] A video file is composed of a file header and a video segment. During segmentation, the video file is divided into multiple video segments according to a predetermined segmentation scheme.

[0028] Step S12: Find the description file corresponding to each video segment from the file header of the video file.

[0029] The file header of the video file contains a description file corresponding to each video segment, and the description file corresponding to each video segment is searched from ...

Abstract

The invention discloses cloud transcoding method and system for video files and aims to greatly increase transcoding speed and improve transcoding efficiency. According to the technical scheme, the method includes: segmenting a video file into a plurality of intermediate-format files recognizable to transcoders; distributing the segmented intermediate-format files to multiple transcoders; and merging the transcoded files.

Description

technical field [0001] The present invention relates to a file transcoding method, in particular to a transcoding method and system for video files which can greatly improve the transcoding speed. Background technique [0002] Video files have multiple encoding formats, and different types of players support different formats. Therefore, in order to meet the video playback needs of users on different platforms, Internet video service providers often need to convert the encoding format of video files. , Video transcoding is a normalized work for Internet companies. [0003] In the prior art, when transcoding is performed, the same video file is performed by a transcoding machine, but the defects of this transcoding method are also obvious. When the video file is very large, the time required for transcoding It will become very long, often delaying the release of new videos due to transcoding. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to sol...
