1. A method of decoding video data, the method comprising:
determining that multiple-hypothesis prediction (MHP) is enabled;
based on determining that MHP is enabled, determining a maximum number of merge candidates for a MHP merge candidate list comprising parsing a syntax element received in a high-level syntax, the syntax element being indicative of the maximum number of merge candidates for the MHP merge candidate list;
based on the maximum number of merge candidates for the MHP merge candidate list, determining the MHP merge candidate list; and
coding the video data based on the MHP merge candidate list.
