1. A video encoding method, comprising:
obtaining a reconstructed video frame from encoded data of an encoded video frame, the encoded video frame comprising at least one encoding block;
filtering the reconstructed video frame, to obtain a filtering gain of each pixel of the at least one encoding block;
for an encoding block in the at least one encoding block, determining, according to a distribution of filtering gains among pixels within the encoding block, whether the encoding block is to be filtered when being decoded at a decoder; and
in response to determining that the encoding block is to be filtered when being decoded at the decoder, including into the encoded data of the encoded video frame an indication information for indicating that the encoding block is to be filtered into the encoded data.
