Re: Cross-apartment COM interface marhsalling

Thanks for replying. It's interesting to know which calls pumps the
message queue. From the performance point of view, it is sad, I know,
but I have to use STA apartments for interaction with DirectShow. For
some unknown reason, from a MTA thread my VfW device won't work (see
http://groups.google.com/group/microsoft.public.win32.programmer.directx.managed/browse_thread/thread/854cddc13d2367cd).


Egbert, what exactly are you saying? I am not releasing anything in the
second thread. And besides, even if under the hood, the
IGRaphBuilder.RemoveFilter loses a reference to the IBaseFilter by
detaching the filter from the graph, that is done in the context of the
first thread, which created the component. So, again, why is this piece
of code not functioning?
