TIMECODE_SAMPLE Structure
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.
