Detailed Description

Defines the structure that contains macroblock related encoding parameter estimates.

Remarks:

An array of IVIDENC1_MbData is provided within the inBufs parameter to IVIDENC1_Fxns::process() when IVIDENC1_DynamicParams::mbDataFlag is set.

XDAS_Int32 IVIDENC1_MbData::mbMode

MB encoding mode

Remarks:

Valid values are:

• 0x00 for skip macroblock
• 0x01 for I Frame macroblock
• 0x02 for P Frame macroblock
• 0x03 for B Frame macroblock
• 0x04 for I Field macroblock
• 0x05 for P Field macroblock
• 0x06 for B Field macroblock
• 0xFF for mbMode not specified

XDAS_Int32 IVIDENC1_MbData::QP

QP estimate.

                                @remarks   A value of 0xFF for QP is
                                           not specified.

XDAS_Int32 IVIDENC1_MbData::mvFwdXY

Forward Motion vector estimate.

                                @remarks   If MVx (XDAS_Int16) and MVy
                                           (XDAS_Int16) are the motion
                                           vectors in the x and y
                                           directions, in quarter pel
                                           units, then
                                @code 
                                mvFwdXY = ((MVx & 0x0000FFFF) << 16) |
                                           (MVy & 0x0000FFFF);
                                @endcode

                                @remarks   A value of 0x7FFF7FFF to
                                           indicate mvFwdXY is not
                                           specified.

XDAS_Int32 IVIDENC1_MbData::mvBwdXY

Backward motion vector estimate.

                                @remarks   The format is the same as
                                           IVIDENC1_MbData::mvFwdXY.
