Title:
VIDEO CODE RATE CONTROL METHOD AND APPARATUS, AND COMPUTER-READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/103200
Kind Code:
A1
Abstract:
A video code rate control method and apparatus, and a computer-readable storage medium. The method comprises: inputting, into a graph neural network, acquired global encoding reference data of a video to be compressed, and outputting code rate association data (S100); and according to the code rate association data, determining the current code rate parameter for controlling a video encoding code rate (S200), wherein the global encoding reference data is used for representing the compression quality of said video, and the code rate association data comprises at least one of the following types: division information of an encoding unit, and a quantization parameter of each encoding block in the encoding unit.
