EnterBitmapGrabMode method switches the media detector to bitmap grab mode and seeks the filter graph to a specified time.
HRESULT EnterBitmapGrabMode( double StreamTime );
Time, in seconds, to which the graph seeks.
Returns an HRESULT value. Possible values include the following:
||The source file does not have a video stream.
||Seek command timed out.
Before calling this method, set the file name and stream by calling IMediaDet::put_Filename and IMediaDet::put_CurrentStream.
This method inserts the Sample Grabber filter into the filter graph. You can then call IMediaDet::GetSampleGrabber to obtain a pointer to the ISampleGrabber interface. Once the media detector enters bitmap grab mode, the various informational methods in IMediaDet do not work.
The IMediaDet::GetBitmapBits or IMediaDet::WriteBitmapBits methods also put the media detector into bitmap grab mode.
