TIMECODE union (ksmedia.h)

  • Article

The TIMECODE union describes a timecode from an external device. This structure is no longer used.

Syntax

typedef union _timecode {
  struct {
    WORD  wFrameRate;
    WORD  wFrameFract;
    DWORD dwFrames;
  };
  DWORDLONG qw;
} TIMECODE;

Members

wFrameRate

Specifies the frame rate.

wFrameFract

Specifies the fractional frame. The full-scale frame is 0x1000.

dwFrames

Specifies a timecode value as a binary frame count.

qw

Specifies the timecode as a quad-word.

Remarks

This structure is defined for the purpose of searching to a timecode based on an absolute track number (ATN) and/or relative time counter (RTC). However, not all devices support searching to a timecode using this structure.
