Problems solved by technology

However, if the video file is not segmented properly and the amount of data allocated to each processor is different, some processors have already transcoded, while other processors process slower and have not yet completed transcoding , so that the overall end time of transcoding is lengthened, which affects the transcoding efficiency

Embodiment Construction

[0022] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. The subsequent description of the specification is a preferred implementation mode for implementing the application, but the description is for the purpose of illustrating the general principle of the application, and is not intended...

Abstract

The invention discloses a video file cutting method for distributed transcoding, and a distributed transcoding method. The method comprises the steps: receiving a source file; carrying out the de-multiplexing of the received source file, and obtaining a video file and an audio file; taking GOP as a unit to segment the video file, and obtaining segmented video files; calculating the time duration when a plurality of transcoding computers process the segmented video files; calculating the segmented video files according to the calculated time duration of each transcoding computer; and transmitting the segmented video files to the corresponding transcoding computers according to the calculation results. The methods provided by the invention enable each transcoding computer to complete transcoding as simultaneously as possible, save transcoding time, and improves the distributed transcoding efficiency.

Description

technical field [0001] The present application relates to video processing, and more specifically, to a video file segmentation method for distributed transcoding and a distributed transcoding method. Background technique [0002] In recent years, with the development of high-definition audio and video, there are more and more types of video formats. Due to the limitations of the video format supported by the video player, it is necessary to use video format conversion software to transcode video files in different formats so that they can run smoothly on the player. The principle of video format conversion is to decode the video through the video format coding specification, and then re-encode it according to the target format coding specification. In order to reduce the amount of data while achieving better picture quality, more advanced coding techniques are adopted, such as H.264 coding technology. However, such advanced coding techniques need to consume more computing...
