Abstract

The embodiment of the invention provides a video processing method and device and an electronic device, wherein the method comprises the steps of carrying out the target detection of a to-be-detectedvideo frame extracted from a to-be-processed video, and determining a main body frame in the to-be-detected video frame according to the detected detection frame information; determining the positioninformation and the size information of the cutting frame in the to-be-detected video frame according to the size information of the playing window of the client by taking the central pixel point of the main body frame as the central pixel point of the cutting frame and the height and width of the to-be-detected video frame; determining position information of the cutting frame in the video framebetween any two adjacent to-be-detected video frames according to the position information and the moving track of the cutting frame; and clipping each video frame according to the position information of the clipping frame in each video frame and the clipping frame size information to obtain the clipped video frame, so that cutting is carried out according to the video content in the horizontal screen video, and it can be guaranteed that the main content of the video is reserved in the cut video frame.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a video processing method, device and electronic equipment. Background technique [0002] With the widespread application of smart terminal devices, people can use various application software installed on smart terminal devices to perform various tasks. The video player app to play the video. [0003] Usually, the videos to be played include horizontal-screen videos and vertical-screen videos. When a smart terminal device uses a vertical screen to play a horizontal-screen video in full screen, the aspect ratio of the video playback window on the smart terminal device is the same as that of the smart terminal device. The aspect ratio of the screen is different. In order to better present the horizontal screen video on the vertical screen full screen, in related technologies, usually all video frames of the horizontal screen video are based on the same pixel poin...
