1. A method of decoding video data, the method comprising:
determining merge candidates for a block of video data;
determining if a merge candidate of the merge candidates includes a base prediction signal and an additional inter prediction signal;
disabling at least one decoder side motion vector derivation technique for use on the base prediction signal of the block of video data based on determining that the merge candidate includes the additional inter prediction signal, wherein the at least one decoder side motion vector derivation technique comprises a multi-pass decoder side motion vector refinement technique;
determining an overall prediction signal with a multiple hypothesis prediction technique using the base prediction signal and the additional inter prediction signal; and
decoding the block of video data using the overall prediction signal.
