Abstract

The invention discloses a video processing method and device, belonging to the technical field of video processing. The method includes: superimposing a transparent layer on the video playback window; when the specified area to be enlarged and displayed in the video playback window is acquired, performing picture capture on the video played in the video playback window to obtain the first picture; according to the specified area, the first picture is cropped to obtain a second picture, the second picture includes the specified area; and the second picture is enlarged and displayed on the transparent layer. The invention does not need to call plug-ins, and can be applied to any browser, thus improving applicability.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a video processing method and device. Background technique [0002] With the development of browsers, more and more users use browsers to watch videos. During the process of watching videos, users may have the need to enlarge and display a partial area of ​​the video screen, so a video processing method is urgently needed. method to meet user needs. [0003] Related technologies call NPAPI (Netscape Plugin Application Programming Interface, Netscape Plugin Application Programming Interface) or ActiveX plug-in to decode the video stream data to obtain YUV data, and cut the YUV data according to the selected area to be enlarged in the video, Obtain the YUV data of the area, and render the YUV data of the area to achieve the effect of zooming in on the area. Among them, YUV data refers to the data in YUV format, YUV is a color coding format, which is divided into ...
