Would you mind elaborating on how VFW is broken in Vista? I have to
admit that I haven't done much with Vista yet, so I'm curious.
I created a push source filter to compress and save some in memory video
samples to a file. I created a push source filter DLL that I can add to
my filter graph. I have a function call in the DLL to pass in a pointer
to the video samples and other information needed to create the AVI
file. How do I expose that function call so I can call it within my
program? The examples in the sdk all generate the video samples within
the filter itself. I want to passes a pointer to an array of video
samples for the source filter to use.
Create a custom interface on your filter. The EzRGB24 filter sample in
the Platform SDK has an example of a custom interface.
