I saw some topic, like How to use/install custom Directshow filter to register a filter, but no code how to use it. Can anybody show a sample how to actual use that filter (pushsource, pushdesktop) to save into AVI?

    You build the pipeline the same way, just instantiating the filter directly as opposed through COM's `CoCreateInstance`. What have you tried? – Roman R. Apr 16 '12 at 12:36
  • I was trying with a grabber sample "vidcap", but it only accepts video sources. When I tried to enforce pushdesktop, it dropped an exception: not supported interface. Is pushsource enough to capture and broadcast/save video stream at all? – John Smith Apr 20 '12 at 23:51
