Document Type and Number:
WIPO Patent Application WO/2019/071984
Kind Code:
A1
Abstract:
The present application relates to a video transcoding method, comprising: acquiring an initial quantization parameter corresponding to an initial encoding unit when encoding an initial compressed video; determining, according to the initial quantization parameter corresponding to the initial encoding unit, a current reference quantization parameter corresponding to a current encoding unit in a current video frame; determining a quantization parameter to be encoded that corresponds to the current encoding unit; determining the difference between the quantization parameter to be encoded that corresponds to the current encoding unit and the corresponding current reference quantization parameter, and increasing the quantization parameter to be encoded that corresponds to the current encoding unit according to the difference so as obtain a target encoding quantization parameter; and encoding the current encoding unit according to the target encoding quantization parameter.
