ICDrawStartPlay macro (vfw.h)
The ICDrawStartPlay macro provides the start and end times of a play operation to a rendering driver. You can use this macro or explicitly call the ICM_DRAW_START_PLAY message.
Syntax
void ICDrawStartPlay(
hic,
lFrom,
lTo
);
Parameters
hic
Handle to a driver.
lFrom
Start time.
lTo
End time.
Return value
None
Remarks
This message precedes any frame data sent to the rendering driver.
Units for lFrom and lTo are specified with the ICM_DRAW_BEGIN message. For video data this is normally a frame number. For more information about the playback rate, see the dwRate and dwScale members of the ICDRAWBEGIN structure.
If the end time is less than the start time, the playback direction is reversed.
