Abstract

The invention provides a video transcoding method and apparatus, a computer device and a storage medium, wherein the method comprises the following steps: obtaining a video to be transcoded, wherein the video format of the video to be transcoded is a standard dynamic range SDR; Mapping a source space of a video to be transcoded to a linear RGB space to obtain a first video; The space of the firstvideo is mapped to the HSI space, the local color gamut of S in the HSI space is expanded to the target color gamut, and the expanded HSI space is mapped to the linear RGB space. Expanding a luminancedomain of the first video to a target luminance domain; The target color gamut and the target brightness gamut are determined according to the video format of the target video, and the video format of the target video is a high dynamic range HDR; The space of the expanded first video is mapped to a source space to obtain a target video. The method realizes the conversion of SDR video into HDR video, so that users can watch the HDR effect of SDR video on the equipment supporting HDR, and the viewing effect is greatly improved.

Description

technical field [0001] The present application relates to the technical field of video processing, and in particular to a video transcoding method, device, computer equipment and storage medium. Background technique [0002] With the development of video technology, many distinctive video format standards have emerged in the market, such as Standard Dynamic Range (SDR for short) and High-Dynamic Range (HDR). Among them, the HDR format is more colorful than the SDR format. [0003] At present, most of the video formats are in the SDR format, but playing the video in the SDR format on the video playback device will make the viewing effect not good. Contents of the invention [0004] The present application actually provides a video transcoding method, device, computer equipment and storage medium, which are used to solve the problem of poor viewing effect when playing video in SDR format in related technologies. [0005] An embodiment of the present application proposes a ...
