Picture transcoding method and device and electronic equipment

Abstract

The embodiment of the invention provides a picture transcoding method, which is applied to electronic equipment with a first processor and a second processor and comprises the following steps of: after obtaining a transcoding task for a picture to be transcoded, splitting the transcoding task into a decoding scaling subtask and a coding subtask; executing, by the first processor, a decoding scaling subtask; when the encoding subtask needs to be encoded according to a first encoding format, the first processor executes the encoding subtask; and when the encoding subtask needs to be encoded according to a second encoding format, enabling the second processor to execute the encoding subtask. A decoding scaling task and a relatively complex encoding task of a first encoding format are executedby a first processor; and the coding task of the second coding format is executed by the second processor, so that different processing tasks are executed by different processing modules in the picture transcoding process, namely, the processing resources of the equipment are utilized more reasonably, and the operation cost and the management cost are reduced.

Description

technical field [0001] The present invention relates to the technical field of picture processing, in particular to a picture transcoding method, device and electronic equipment. Background technique [0002] With the rapid development of electronic products, people's life and entertainment are increasingly dependent on various electronic products. For example, people often use mobile phones, tablet computers and other electronic products to browse pictures, so the background server needs to execute a large number of jpg (Joint Photographic Group ) original image to jpg thumbnail, or jpg original image to webp thumbnail and other image format transcoding tasks. [0003] Currently, image format transcoding tasks can be performed using FPGA (Field-Programmable Gate Array, Field Programmable Gate Array). Each transcoding system performs one type of image format transcoding tasks. task, you need to add a transcoding system, and use multiple transcoding systems to perform transc...

AI Technical Summary

Problems solved by technology

Although the current image format transcoding method can realize image transcoding tasks in various formats, and can improve the processing speed of transcoding, the operation cost and management cost are increased due to the unreasonable utilization of processing resources.
