TIMECODE_SAMPLE structure (ksmedia.h)

  • Article

The TIMECODE_SAMPLE structure describes a complete timecode.

Syntax

typedef struct tagTIMECODE_SAMPLE {
  LONGLONG qwTick;
  TIMECODE timecode;
  DWORD    dwUser;
  DWORD    dwFlags;
} TIMECODE_SAMPLE;

Members

qwTick

Specifies a reference time, in 100-nanosecond units.

timecode

Specifies the TIMECODE structure.

dwUser

Specifies packed SMPTE user-bits.

dwFlags

Specifies any optional timecode flag masks.

Flag Meaning
AM_TIMECODE_FLAG_FCM Frame-code mode; 0 = nondrop; 1 = drop.
AM_TIMECODE_FLAG_CF Color-frame flag.
AM_TIMECODE_FLAG_FIELD Field flag.
AM_TIMECODE_FLAG_DF Drop-frame flag (from flags in actual timecode on external media).
AM_TIMECODE_COLORFRAME Specifies frame, in color sequence.
AM_TIMECODE_COLORSEQUENCE Duration, in frames, of complete sequence.
AM_TIMECODE_FILMSEQUENCE_TYPE One of the FILM_SEQUENCE_XXX tokens.
ED_DEVCAP_TIMECODE_READ Read SMPTE timecode; applies to DV camcorders.
ED_DEVCAP_ATN_READ Read the absolute track number (ATN); applies to DV camcorders.
ED_DEVCAP_RTC_READ Read the relative time counter (RTC); applies to MPEG camcorders.

Remarks

Any ED_Xxx tokens are defined in xprtdefs.h in the DirectX SDK.

The upper 16 bits in dwFlags are reserved for future use and must be set to zero.

Requirements

Requirement Value
Header ksmedia.h (include Ksmedia.h)
