okie, i'll add a getversion function in next release.
you can use set event function to set it event to your main windows.
function BassVideo_SetEventNotify(Handle : HSTREAM; hwnd: OAHWND; lMsg: Longint; lInstanceData: Longint) : BOOL; stdcall;
Handle :[in] channel handle
hwnd : [in] Handle to the window, or NULL to stop receiving event messages.
lMsg : [in] Window message to be passed as the notification. (should be WM_EVENT)
lInstanceData : [in] Value to be passed as the lParam parameter for the lMsg message. (should use WM_Event_Lparam)
after that in your wnd proc code
procedure TForm1.WndProc(var Msg: TMessage);
var EVCode, p1, p2 : integer;
begin
inherited;
case Msg.Msg of
....
WM_EVENT : begin
if BassVideo_GetEvent(chan, EVCode, p1, p2, 200) then
begin
case EVCode of
EC_BUFFERING_DATA :
begin
end;
EC_COMPLETE :
begin
end;
end;
end;
end;
end;
end;
The EC_COMPLETE event indicates that playback has completed normally.
The EC_USERABORT event indicates that the user has interrupted playback. Video renderers send this event if the user closes the video window.
The EC_ERRORABORT event indicates that an error has caused playback to halt.
this is from directshow sdk :
