#define JP2K_YCbCr1_SPACE   1
 Commonly used for data that originated from a video signal.
#define JP2K_YCbCr2_SPACE   3

 This is an opponent representation for the JP2K_CMYK_SPACE.
#define JP2K_CIELab_SPACE   14
 This is the CIE Lab colour space.
#define JP2K_bilevel2_SPACE   15

typedef struct _JPEG2000INFOHEADER2 * PJPEG2000INFOHEADER2
 

Extension to the BITMAPINFOHEADER which is widely used in Video For Windows and DirectShow.

typedef struct _MJ2CINFOHEADER MJ2CINFOHEADER
 

Using BITMAPINFOHEADER when JPEG2000INFOHEADER or JPEG2000INFOHEADER2 are absent.

We map a new struct MJ2CINFOHEADER on BITMAPINFOHEADER.

This is essentially usefull to add extended information to MJ2C AVI created without the JPEG2000INFOHEADER(2) in the 'strf' chunck.

This way 'old' MJ2C AVI can be patch to support new features like h/w deinterlacing or color correction.

It is resonably safe because we overide elements above which are commonly unused and set to 0

  • LONG biXPelsPerMeter;
  • LONG biYPelsPerMeter;
  • DWORD biClrImportant;
