24/**
25 * Function:  omxVCM4P2_MEGetBufSize   (6.2.4.1.1)
26 *
27 * Description:
28 * Computes the size, in bytes, of the vendor-specific specification
29 * structure for the following motion estimation functions:
30 * BlockMatch_Integer_8x8, BlockMatch_Integer_16x16, and MotionEstimationMB.
31 *
32 * Input Arguments:
33 *
34 *   MEmode - motion estimation mode; available modes are defined by the
35 *            enumerated type OMXVCM4P2MEMode
36 *   pMEParams - motion estimation parameters
37 *
38 * Output Arguments:
39 *
40 *   pSize - pointer to the number of bytes required for the specification
41 *            structure
42 *
43 * Return Value:
44 *
45 *    OMX_Sts_NoErr - no error
46 *    OMX_Sts_BadArgErr - one or more of the following is true:
47 *    -    an invalid value was specified for the parameter MEmode
48 *    -    a negative or zero value was specified for the
49 *         parameter pMEParams->searchRange
50 *
