Embodiment Construction

[0047] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Apparently, the described embodiments are only some of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the embodiments of the present application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the embodiments of the present application.

[0048] In the prior art, the method for extracting a thumbnail is to use an interface in the terminal system (such as the getFrameAtTime interface of the MediaMetadataRetriever class) to extract an image at a specified display time stamp as a thumbnail. However, the specific implementation of this method of extracting thumbnails using the interface in the terminal system depends on the manufacturer, and it takes a long tim...

Abstract

The embodiment of the invention provides a thumbnail extraction method and device, and relates to the technical field of computers, and the method comprises the steps that electronic equipment can obtain a thumbnail extraction instruction for a video file, and the thumbnail extraction instruction comprises a target display timestamp; then, performing software decoding on the video file to obtain image data of a target key frame of which the display timestamp is closest to the target display timestamp, and determining a target thumbnail according to the image data of the target key frame. According to the scheme, the electronic equipment can determine the target thumbnail to be extracted according to the image data of the key frame, so that the thumbnail extraction efficiency is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for extracting thumbnails. Background technique [0002] With the popularization of smart devices and the substantial improvement of the hardware performance of smart devices, people's demand for using short videos to express themselves is increasingly strong. Short video has become a very hot field on smart devices. [0003] In the editing stage of the short video, in order to improve the user experience, it is necessary to extract and display thumbnails from the original video files. At present, the method for extracting thumbnails is to use an interface in the terminal system (such as the getFrameAtTime interface of the MediaMetadataRetriever class) to extract an image at a specified display time stamp as a thumbnail. However, the specific implementation of this method of extracting thumbnails using the interface in the terminal system depends...
