The DXVA_MVvalue structure is sent by the host decoder to the accelerator to specify the two-dimensional motion vector value.
horzSpecifies the horizontal component of the value of a motion vector. Contains a signed integer motion offset in half-sample units. The value of this member will be an even integer if the bMVprecisionAndChromaRelation member of DXVA_PictureParameters equals 2 (H.261-style motion supporting only integer-sample offsets).
vertSpecifies the vertical component of the value of a motion vector. Contains a signed integer motion offset in half-sample units. The value of this member will be an even integer if the bMVprecisionAndChromaRelation member of DXVA_PictureParameters equals 2 (H.261-style motion supporting only integer-sample offsets).
The DXVA_MVvalue structure is used in the DXVA_MBctrl_P_HostResidDiff_1 and DXVA_MBctrl_P_OffHostIDCT_1 structures.
