Abstract

The invention discloses a video coding method and device, a terminal and a memory medium and belongs to the technical field of video processing. The method comprises the steps of obtaining a to-be-processed target video, wherein the target video comprises n target video frames which are arranged in sequence; carrying out target detection on an ith target video frame through adoption of a target detection model, thereby obtaining a target region in the target video frame; and carrying out video coding through utilization of a region of interest (ROI) coding algorithm according to the target regions corresponding to the n target video frames, thereby obtaining a coded target video. According to the embodiment of the invention, the target detection is carried out on the target video frames through adoption of the target detection model and the target regions namely ROI are dynamically determined along with the change of video images, so the terminal can carry out the video coding based onthe dynamically determined ROI through adoption of the ROI coding algorithm subsequently, the coding quality and stability of the target regions are effectively ensured, moreover, a coding rate of the target video is reduced, and the video coding efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of video processing, and in particular to a video encoding method, device, terminal and storage medium. Background technique [0002] Video coding refers to a technology for converting a file in a first video format into a file in a second video format by using a specific compression method. [0003] In the related art, the method for encoding a static image includes: the terminal acquires the static image to be processed, and encodes a specified area in the static image at a fixed position using a region of interest (ROI) encoding algorithm, and obtains the encoded of static images. [0004] The above-mentioned ROI encoding algorithm is usually applied to encoding a specified area in a static image. For a dynamic image such as a video, the ROI area cannot be dynamically adjusted according to the area that the user focuses on. For example, in a virtual scene, the virtual object is active. For dif...
