C++/VB - Sending event from a decoder

Does anyone know a way to send an event up to the filter graph manager
from a DMO filter?  In my CSource filters, I do something like:

m_pFilter->NotifyEvent(E_BLAH, hr, blah);

...but I do not see a comparable call for DMOs.

Any help is much appreciated.

There is no way. DMOs are designed to be usable outside of a
DS graph, so they do not know anything about the graph's
IMediaEventSink. And there is no DMO-specific signalling
mechanism (not even for stream discontinuities or preroll).

How citrix is able to format does not really matter. Of course a decoder can be any of: 1. a DirectShow filter in a DirectShow graph 2. a DMO in a DirectShow graph 3. a VCM codec in a DirectShow graph 4. an ACM codec in a DirectShow graph 5. a DMO in the WMReader

Custom DVR Interface Using DirectShow C++ / VB I am fairly new to DirectShow and could use some thoughts on a solution for a interfacing to a software DVR to a file and have been able to play that file with VLC and simple DirectShow based players. I have found DirectShow filters that can play the file, they include an MPEGDemultiplexer and MPEG4Decoder. I have viewed built a first cut (experiment) at a solution. I have been able to construct a DirectShow solution by modifying the SDK sample async file source reader. The solution works (very crudely approach this problem of interfacing to the DVR.
