Abstract

The invention provides a video playback area identification method and apparatus, and a media playback device. The method comprises the steps of capturing an image of a video playback page; extractingcolor feature data of each pixel in the image; calculating the number of pixels with the same color feature data on each pixel line in the image; selecting two pixel lines as target pixel lines, wherein the number of the pixels with the same color feature data on the two selected pixel lines exceeds a preset value; and determining a video playback area in the video playback page according to thetwo target pixel lines. The method can precisely determine a specific playback area in video playback by a multimedia playback device, has a small calculation amount but a high determining speed, andfacilitates subsequent video analysis.

Description

technical field [0001] The present invention relates to the technical field of video image processing, in particular, to a method and device for identifying a video playing area, and a media playing device. Background technique [0002] When playing a video on a multimedia playback device, it is necessary to analyze the played video, such as determining and analyzing the first frame, frame rate, and playback speed of the video. These video analyzes need to capture the video content played in the video playback area to obtain accurate analysis results. The inventors found that there is no method for accurately determining the video playback area in the prior art, which brings inconvenience to video analysis. Contents of the invention [0003] In view of this, the present invention provides a method for identifying a video playing area, which can accurately determine the video playing area on a multimedia playing device. [0004] The technical scheme provided by the invent...
