Define Documentation

#define XVID_ADAPTIVEQUANT   0x00000080

Adaptive quantization. informs xvid to perform an adaptative quantization using a Luminance masking algorithm

#define XVID_ALTERNATESCAN   0x00001000

Deprecated: This flag is no longer used.

#define XVID_CUSTOM_QMATRIX   0x00000004

Use custom quantization matrices. This flag forces XviD to use custom matrices passed to encoder in XVID_ENC_FRAME structure (members quant_intra_matrix and quant_inter_matrix)

#define XVID_GRAYSCALE   XVID_GREYSCALE

XVID_GREYSCALE alias. United States locale support.

#define XVID_GREYSCALE   0x01000000

Discard chroma data. This flags forces XviD to discard chroma data, this is not mpeg4 greyscale mode, it simply drops chroma MBs using cbp == 0 for these blocks

#define XVID_H263QUANT   0x00000010

Use H263 quantization. This flag forces XviD to use H263 quantization type

#define XVID_HALFPEL   0x00000040

Halfpel motion estimation. informs xvid to perform a half pixel motion estimation.

#define XVID_HINTEDME_GET   0x00002000

Gets Motion vector data from ME system. informs xvid to return Motion Estimation vectors from the ME encoder algorithm. Used during a first pass.

#define XVID_HINTEDME_SET   0x00004000

Gives Motion vectors hint to ME system. informs xvid to use the user given motion estimation vectors as hints for the encoder ME algorithms. Used during a 2nd pass.

#define XVID_INTER4V   0x00008000

Inter4V mode. forces XviD to search a vector for each 8x8 block within the 16x16 Macro Block. This mode should be used only if the XVID_HALFPEL mode is activated (this could change in the future).

#define XVID_INTERLACING   0x00000400

MPEG4 interlacing mode. Enables interlacing encoding mode

#define XVID_LATEINTRA   0x00000200

Unknown. Deprecated: This flag is no longer used.

#define XVID_LUMIMASKING   0x00000100

Lumimasking flag. Deprecated: This flag is no longer used.

#define XVID_ME_EPZS   0x00100000

Use EPZS ME algorithm. Switches XviD ME algorithm to EPZS

#define XVID_ME_FULLSEARCH   0x00040000

Unused. Do not use this flag (reserved for future use)

#define XVID_ME_LOGARITHMIC   0x00020000

Unused. Do not use this flag (reserved for future use)

#define XVID_ME_PMVFAST   0x00080000

Use PMVfast ME algorithm. Switches XviD ME algorithm to PMVfast

#define XVID_ME_ZERO   0x00010000

Unused. Do not use this flag (reserved for future use)

#define XVID_MPEGQUANT   0x00000020

Use MPEG4 quantization. This flag forces XviD to use MPEG4 quantization type

#define XVID_TOPFIELDFIRST   0x00000800

Unknown. Deprecated: This flag is no longer used.
