1. An in-loop filtering implementation method, comprising:
performing, based on at least two original colour components of a to-be-filtered picture, component processing respectively on each of the at least two original colour components, to obtain at least two colour components after the component processing;
performing in-loop filtering processing based on the at least two colour components after the component processing;
further comprising: acquiring the to-be-filtered picture, comprising:
performing video encoding processing on an original picture, and taking a generated reconstructed picture as the to-be-filtered picture; or
performing video encoding processing on the original picture to generate a reconstructed picture; and performing preset filtering processing on the reconstructed picture, and taking the picture after preset filtering as the to-be-filtered picture; wherein the performing in-loop filtering processing based on the at least two colour components after the component processing comprises: inputting the at least two colour components at one time: wherein the at least two colour components comprises two of a first colour component, a second colour component and a third colour component of the to-be-filtered picture, and the at least one filtered colour component comprises only one of a filtered first colour component, a filtered second colour component, or a filtered third colour component of the to-be-filtered picture of the to-be-filtered picture.
