Embodiment Construction

[0131] In order to make the objectives, technical solutions and advantages of the embodiments of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0132] It is understood that the terms "first", "second" and the like used in this application may be used herein to describe various concepts, but these concepts are not limited by these terms unless otherwise specified. These terms are only used to distinguish one concept from another.

[0133] The method provided by the embodiment of the present application can be applied to a live broadcast scenario. When the live broadcast terminal performs live broadcast, the first ROI QP value is used to encode the collected live broadcast video data, and then the method provided by the embodiment of the present application is used. When the live video data encoded by using the first ROI QP value meets the adjustment condition...

Abstract

The present application discloses a video adjustment method, device, computer equipment and storage medium, which belong to the technical field of video processing. The method includes: using the first ROI QP value to encode the first video data and then decoding to obtain the second video data; and obtaining the first quality parameter and the first quality parameter of the second video data according to the first video data and the second video data. The second quality parameter of the target area in the second video data; the second video data satisfies the first adjustment condition, then the first ROI QP value is adjusted according to the first quality parameter and the second quality parameter to obtain the adjusted second ROI The QP value realizes the adaptive adjustment of the ROI QP value according to the quality of the video data, so that when the code rate in the video data is determined according to the adjusted ROI QP value, the accuracy of the code rate allocated in the video data can be guaranteed, and then Improve the image quality of video data.

Description

technical field [0001] The present application relates to the technical field of video processing, and in particular, to a video adjustment method, apparatus, computer equipment and storage medium. Background technique [0002] With the rapid development of video processing technology and people's increasing requirements for video playback effects, ROI (Region Of Interest, region of interest) technology is usually used to distinguish the target area and non-target area in the video data, using different The code rate encodes the target area and the non-target area separately. [0003] In the related art, when using ROI technology to encode video data, an initial bit rate is set, a target area and a non-target area of ​​each video data in the video data are obtained, and a fixed ROI QP (Quantization Parameter, Quantization Parameter) is set for the target area. parameter) value, to determine the code rate corresponding to the target area and the code rate corresponding to th...
