1. A method performed by at least one processor in a video decoder, the method comprising:
receiving a coded video bitstream including a current picture that includes at least one block and obtaining a syntax element from the at least one block, the syntax element indicating a flip mode;
determining that the at least one block is to be predicted in a reconstruction-reordered intra block copy (RR-IBC) mode;
applying reconstruction flip to the at least one block by predicting a flip pattern for the at least one block based on neighboring reconstruction samples of the at least one block and a corresponding reference block of the at least one block; and
decoding the at least one block based on the flip mode and the predicted flip pattern,
wherein the at least one block includes a template that includes neighboring reconstructed samples on at least two sides of the at least one block.
