Abstract

The invention discloses a video playing method and device, a storage medium and an electronic device. The method comprises: determining a target display area in a plurality of display areas of a display device, the plurality of display areas correspond to a plurality of video channels, and each display area is used for displaying one path of video data; according to the resolution of the target display area, lowering the resolution of a video frame picture in an initial picture group GOP sequence of target road video data to be displayed in the target display area to obtain a target GOP sequence; and playing the target GOP sequence in an inverted order in the target display area. According to the invention, the technical problem of equipment operation performance reduction caused by overlarge memory consumption in a video playing method in the related art is solved.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a video playing method, device, storage medium and electronic device. Background technique [0002] On monitoring equipment, for example, NVR (Network Video Recorder, network hard disk video recorder) and DVR (Digital Video Recorder, hard disk video recorder), the real-time playback display on the video screen is to play the video picture in real time in reverse order. [0003] The following two real-time playback solutions are provided in the related art. For solution 1, there is a GOP (Group of Pictures) sequence in the video code stream. To achieve real-time playback, the GOP sequence needs to be decoded sequentially, and the decoded original YUV ("Y" indicates brightness, " U" and "V" represent chroma, concentration) the picture is saved, and the picture is played in reverse order when playing. The determination of option 1 requires a huge amount of memory to save the origi...
