Embodiment Construction

[0061] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described implementation Examples are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0062]With the popularity of online video services and the continuous increase of network bandwidth, online video service providers are facing more and more high-definition or ultra-high-definition video transcoding requirements. Due to the high resolution and high bit rate of high-definition video and ultra-high-definition video, the comp...

Abstract

An embodiment of the invention discloses a method, a device and a system of video transcoding. The method of video transcoding comprises the following steps that: a video file to be transcoded and a target code rate of the video file to be transcoded are obtained; the video file to be transcoded is divided to obtain at least two video sub-files; and the video sub-files obtained by division are distributed to a plurality of transcoders and the target code rate of the video file to be transcoded is transmitted to the transcoders distributed with the video sub-files, so that the video sub-files obtained through distribution are transcoded by the transcoders distributed with the video sub-files according to the target code rate of the video file to be transcoded, and the video sub-files with the target code rate are generated, wherein any one video sub-file is only distributed to one transcoder. By applying the technical scheme, the embodiment of the invention is capable of transferring the transcoders to transcode one video file synchronously, so that the transcoding time is reduced and the transcoding efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a video transcoding method, device and system. Background technique [0002] With the rapid development of network multimedia technology, the playback form of video files is no longer limited to a specific video stream, and gradually appeared standard definition video stream, high definition video stream, ultra high definition video stream, etc. to meet different network playback environments video stream. This requires the video service provider to transcode the video file, so as to obtain video code streams of various definitions for playback by the video player. [0003] When the existing video transcoding technology performs video transcoding, a complete video file is assigned to a transcoder for transcoding. Since the video file is large, it will take a long time to transcode a complete video file on a transcoder, and the efficiency is low. Especially whe...
