API Reference Guide > Core Component API Reference > Core Component Functions Reference > Multimedia Functions > IG_mult_current_frame_seek_time

This function seeks to the given absolute time in milliseconds since the beginning of the multimedia instance.


Copy Code
AT_ERRCOUNT ACCUAPI IG_mult_current_frame_seek_time(
        HIGMULT hMult, 
        AT_UINT msTime


Name Type Description
hMult HIGMULT Multimedia instance handle.
msTime AT_UINT Time to seek to in milliseconds.

Return Value:

Returns the number of ImageGear errors that occurred during this function call. If there are no errors, the return value is IGE_SUCCESS.

Supported Raster Image Formats:

This function does not process image pixels.


Copy Code
/* Grab frames at two second intervals */
AT_ERRCOUNT nErrcount;  /* Number of errors on stack */
HIGMULT hMult;          /* Multimedia instance handle */
AT_BOOL bValid;         /* Is the current frame valid? */
AT_UINT msTime = 0;     /* Timestamp used for seeking */
HIGEAR hIGear;          /* HIGEAR handle of image */
while (IG_mult_current_frame_is_valid(hMult, &bValid) == IGE_SUCCESS && bValid)
        nErrcount = IG_mult_current_frame_image_get(hMult, &hIGear);
        msTime += 2000;
        nErrcount = IG_mult_current_frame_seek_time(hMult, msTime);


This function locates the frame that would be visible at this time under normal speed playback conditions and makes this the current frame. Seeking to a time of 0 will seek to the beginning, 1000 will seek to one second after the beginning, and so on.
