TIMECODE (Windows CE 5.0)

Send Feedback

This structure contains basic timecode frame count information.

typedef struct tagTIMECODE {WORD wFrameRate;WORD wFrameFract;WORD dwFrames;}TIMECODE;

Members

  • wFrameRate
    Number of frames per second. Specify with one of the following values.
    Value Description
    ED_FORMAT_SMPTE_30 30 frames per second.
    ED_FORMAT_SMPTE_30DROP 30 frames per second drop frame (actual rate 29.97 fps).
    ED_FORMAT_SMPTE_25 25 frames per second.
    ED_FORMAT_SMPTE_24 24 frames per second.
  • wFrameFract
    Fractional frame. Full scale is 0x1000.
  • dwFrames
    Timecode value as a binary framecount.

Remarks

Fractional frame can be used to indicate temporal offset into frame when timecode was actually read from an external device; for example, wFrameFract=0x7ff means the timecode value was read from the device at the end of the first video field.

Note   Because timecode commonly enters or leaves computer systems as ASCII values, conversion helper methods that convert the ASCII values to and from binary framecounts are supplied in the sample filter.
