Problems solved by technology

This method has certain accuracy when the number of samples is limited and the changes are small, but in the actual transcoding process, the data diversity of the source audio and video far exceeds the historical data used as a reference, and the changes in the parameters of the source audio and video and the target audio and video , changes in transcoding hardware resources will increase the deviation of the estimate

Embodiment 1

[0047]Seefigure 1 , This embodiment proposes a method for estimating the duration of audio and video transcoding tasks, including the following steps:

[0048]S100: In response to the current audio and video transcoding task request, obtain a source audio and video file to be transcoded.

[0049]The current audio and video transcoding task request in this embodiment may be based on a request initiated by the user in real time, or may be based on a request initiated automatically and regularly by the system. For example, when a user uploads a self-photographed audio and video file to the video playback platform of this application, the user initiates a current audio and video transcoding task request to convert the format of the self-photographed audio and video file into a video playback platform suitable for this application Format. Or the system processes stored audio and video files in different formats from the video playback platform of this application in batches according to preset...

Abstract

The invention provides a duration estimation method and a duration estimation device for an audio and video transcoding task. The method comprises the steps: responding to an audio and video transcoding task request, and obtaining a to-be-transcoded source audio and video file; obtaining a first audio and video parameter of the source audio and video file; determining a second audio and video parameter of a target audio and video file corresponding to the source audio and video file according to the first audio and video parameter; collecting resource parameters required for executing the audio and video transcoding task; and inputting the first audio and video parameter, the second audio and video parameter and the resource parameter into a duration estimation model to determine the estimated duration of transcoding the source audio and video file into the target audio and video file. The task processing efficiency can be effectively improved, and unnecessary resource waste generatedin the task execution process is avoided.

Description

Technical field[0001]This application relates to the technical field of audio and video processing, and in particular to a method and a device for estimating the duration of audio and video transcoding tasks.Background technique[0002]Audio and video transcoding refers to converting an audio and / or video stream that has been compressed and encoded into another audio and / or video stream to adapt to different network bandwidths, different terminal processing capabilities, and different user requirements. At present, in order to meet the needs of a large number of transcoding tasks, cloud computing technology is usually combined to perform audio and video transcoding tasks in batches on large-scale server clusters. At present, when a large number of transcoding tasks are executed, the time required for the current transcoding task is usually estimated to be used to rationally schedule and allocate different tasks.[0003]At present, a common method for estimating duration is to estimate t...
