First of all, there is sample code at The March Hare‘s website: The IAMGraphBuilderCallback class can be used to remove problematic dshow filters when building a graph with intelligent connect. This sample does not provide…
Sharing memory allocators between input and output pins is an important concept to keep performance of filter graph.

In an intention to accompany the post with useful DirectShow related information, here is the link list of most important DirectShow resources on…
Another example of a negligence with a cost of incompatibility and enormous amount of support time. Ahead Nero installs a number of DirectShow filters into $(Program Files)\Common Files\Ahead\DSFilter directory. One of the files is NeResize.ax and it hosts a Nero Resize filter. Let us take a closer look: CLSID: {30002E0C-C574-481E-A5DE-90AE54A79E10} (note that Nero 8 ships…
