Abstract

The invention discloses a video coding method and apparatus, and a storage medium, and belongs to the technical field of video processing. The method comprises the following steps: determining a target resolution of a to-be-coded video according to the initial resolution of the to-be-coded video, wherein the target resolution is a codable resolution supported by a coding terminal, and the target resolution is greater than the initial resolution; adding invalid pixels to each frame of image in the to-be-coded video, so that the resolution of the image with the added invalid pixels is equal to the target resolution; and performing video coding on the image with the added invalid pixels to obtain a code stream, adding cutting information to the code stream, wherein the cutting information is used for indicating the positions of the invalid pixels in each frame of image. By adoption of the video coding method and apparatus disclosed by the invention, the following problem in related art is solved: in order to ensure the breadth length ratio, the size of each frame of image in the decoded video needs to be compressed, thereby being liable to cause an image deformation phenomenon, resulting in poor display effect of the image on the terminal. The video coding method and apparatus disclosed by the invention is applied to video coding.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a video encoding method and device, and a storage medium. Background technique [0002] H.264 is a next-generation digital video compression format following MPEG4 jointly proposed by the International Organization for Standardization (English: International Organization for Standardization; abbreviation: ISO) and the International Telecommunication Union (English: International Telecom Union; abbreviation: ITU). The H.264 coding standard is a joint venture formed by the ITU-T Video Coding Experts Group (English: Video Coding Experts Group; VCEG for short) and the ISO / IEC Moving Pictures Experts Group (English: Moving Pictures Experts Group; short: MPEG). A highly compressed digital video coding standard proposed by the Video Group (English: Joint Video Team; abbreviation: JVT), which is usually called the H.264 / AVC standard. [0003] Due to the uneven compatibi...
