Returns the header information about the video clip specified.
Declaration
function AVIHeaderInfo (AVIFile: string; HeaderAttribute: THeaderAttribute): string;
wchar_t *__fastcall AVIHeaderInfo(wchar_t *AVIFile, THeaderAttribute HeaderAttribute);
Function AVIHeaderInfo (AVIFile As String, HeaderAttribute as THeaderAttribute) as String
Description
Used to retrieve the THeaderAttribute 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;
