Public Function AVIHeaderInfo(AVIFile As String, HeaderAttribute As THeaderAttribute) As String
C++/Qt
wchar_t * AVIHeaderInfo (wchar_t *AVIFile, THeaderAttribute HeaderAttribute);

Retrieves the THeaderAttribute header information about the video clip specified. When the clip is opened a first time, all the whole THeaderAttribute attributes are read, so the clip is not re-opened during the subsequent calls, unless a different file name is specified. E.g.:

procedure TfrmMainForm.Button2Click(Sender: TObject);

begin

Showmessage (VideoGrabber.AVIHeaderInfo('MyFirstVideoClip.avi', ha_Title));

Showmessage (VideoGrabber.AVIHeaderInfo('MySecondVideoClip.asf', ha_Copyright));

end;
