1. A video processing method, comprising:
obtaining a current frame of a video;
partitioning the current frame into one or more areas including a current area, wherein the current area includes one or more coding tree unit (CTU) rows including a first CTU row and a second CTU row;
obtaining the first CTU row, the first CTU row comprising multiple CTUs in a first sequence;
detecting a first beginning CTU in the first sequence of the multiple CTUS;
in response to detecting the first beginning CTU, initializing a first history-based motion vector prediction (HMVP) list for the first CTU row;
processing the first CTU row based on the initialized first HMVP list;
obtaining the second CTU row, the second CTU row comprising multiple CTUs in a second sequence;
detecting a second beginning CTU in the second sequence of the multiple CTUS;
in response to detecting the second beginning CTU, initializing a second HMVP list for the second CTU row; and
processing the second CTU row based on the initialized second HMVP list.
