Embodiment Construction
[0058] figure 1 It is a flowchart of Embodiment 1 of the video playback method of the present invention, and the video playback method includes:
[0059] A. Duplicate the current video frame into the same two, and divide one of the video frames evenly from left to right to obtain the first image and the second image, and divide the other video frame evenly up and down to obtain the third image and the fourth image Image, for example, if the resolution of the current video frame is 1280*720, then the resolutions of the two images after the left and right segmentation are 640*720 respectively, and the resolutions of the two images after the upper and lower segmentation are 1280*360;
[0060] B. Carry out edge detection on the first image and the third image respectively to determine whether the current video frame is a valid video frame. The purpose of this edge detection is mainly to exclude video frames that are completely black, completely white, and have no obvious edges. A...

The invention discloses a video playing method and equipment. The method comprises steps that: a video frame is copied to acquire two identical ones, left and right segmentation on one of the two is carried out to acquire a first image and a second image, and upper and lower segmentation on the other one is carried out to acquire a third image and a fourth image; edge detection on the first and the third images is respectively carried out, when the present video frame is an effective video frame, and row numbers ic1 and ic2 and column numbers jc1 and jc2 of the first and third images having maximum edge points are respectively counted; respectively in the first and second images, the ic1 and jc1 pixel points are taken as centers to open M*M windows, respectively in the third and fourth images, the ic2 and jc2 pixel points are taken as centers to open M*M windows, similarity of the opened windows in the first and second images are calculated, and similarity of the opened windows in the third and fourth images are calculated; the video type is determined, and the video is played according to the video type. The method can rapidly identify the video type, so the video is played in a proper playing mode.
Description
technical field [0001] The invention relates to the field of multimedia playing, in particular to a video playing method and device. Background technique [0002] In the existing stereoscopic video storage methods, many 3D stereoscopic videos are stored in common 2D video storage methods. For example, videos from two viewpoints are generally stored in a left-right format or a top-bottom format. That is to say, there is no difference between 3D stereoscopic video and ordinary 2D video information in terms of file storage information. When playing, it is easy to cause 3D stereoscopic video to be played in ordinary 2D playback mode, and stereoscopic effect cannot be presented. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a video playing method and device capable of identifying the video type, aiming at the above-mentioned defect of the prior art that the video type cannot be identified during playback. [0004] ...
