Problems solved by technology

But the disadvantage of this is that it needs to be realized by configuring certain registers, but the number of registers is limited, usually 16 groups or 32 groups, and cannot be flexibly increased; and it can only form a rectangular area, which limits the interception space, resulting in The problem that the QP setting in the rectangular area is not flexible enough

Abstract

The present invention provides a video encoding method based on quantization parameter configuration, comprising: acquiring a target video image, dividing the target video image into macroblocks; reading a pre-generated QP compression table, where the QP compression table indicates the The QP value of each macroblock in the target image; the current macroblock in the target image is encoded according to the QP value indicated in the QP compression table. According to the video coding method and device provided by the embodiments of the present invention, the target image is subjected to partition marking processing by using the QP compression table. Because the QP compression table can be arbitrarily configured, it is not limited by the number of ROI regions, making the QP adjustment more flexible. The image processing and compression process is more detailed and easy to control.

Description

technical field [0001] The present invention relates to the technical field of video coding, in particular to a video coding method based on quantization parameter configuration. Background technique [0002] In recent years, applications based on intelligent video processing have been widely used in various electronic devices, and most applications need to transmit compressed video to back-end servers or other communication terminals for further processing. High-resolution video (also known as ultra-high-definition video) is becoming more and more common. This type of content ranges from HD video at 1920x1080 pixels per frame to higher resolution video either directly using advanced optics or from stitched views from multiple cameras. Due to bandwidth constraints, it is often not possible to deliver this type of content in its entirety directly to the end user. [0003] Therefore, in the video processing technology, the concept of Region-of-Interest (ROI) is proposed, so ...
