TIMECODE_SAMPLE Structure

Microsoft DirectShow 9.0

The TIMECODE_SAMPLE structure contains complete timecode information.

Syntax

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

Members

qwTick

Reference time, in 100-nanosecond units.

timecode

TIMECODE structure.

dwUser

Packed SMPTE userbits.

dwFlags

Timecode flag masks. Specify one or more of the following values.

Value	Description
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 defines.
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. This constant is defined in the header file Xprtdefs.h.
ED_DEVCAP_RTC_READ	Read the relative time counter (RTC); applies to MPEG camcorders. This constant is defined in the header file Xprtdefs.h.

Remarks

The upper 16 bits in dwFlags are reserved for future use; set to zero.

Requirements

Header: Dshow.h.
