Problems solved by technology

Due to the high compression ratio, the decoding efficiency of images in Webp format is slower than that of png jpeg. Currently, webp on android phones generally uses CPU soft decoding, which is inefficient.

Abstract

The embodiment of the invention provides a picture decoding method and a related product. The picture decoding method comprises the steps: obtaining a target picture, wherein the target picture is a picture in a webp format; processing the target picture into a to-be-processed video in a vp8 video format by utilizing a preset mode; and decoding the to-be-processed video by using a vp8 decoder to obtain a decoded picture corresponding to the target picture. Thus, the target picture is processed into the to-be-processed video in the vp8 video format, and then the to-be-processed video is decodedby using the vp8 decoder, so compared with decoding of the target picture in the webp format by using a CPU, the method is higher in decoding speed, and is higher in decoding efficiency.

Description

technical field [0001] The present application relates to the technical field of picture processing, in particular to a picture decoding method and related products. Background technique [0002] At present, pictures in the network still occupy a large part of traffic, especially for mobile terminals. Therefore, how to reduce the size of pictures without visual distortion is very important for saving bandwidth and battery power. However, at present, the optimization of commonly used image formats such as JPEG, PNG, and GIF has almost reached the extreme. Therefore, Google proposed a new image compression format in 2010 - WebP, which provides new possibilities for image optimization. [0003] WebP provides lossless and lossy compression capabilities for network images, and supports transparent channels under lossy conditions. According to official experiments, lossless WebP reduces the size by 26% compared to PNG; lossy WebP reduces the size by 25% to 34% compared to JPEG un...
