Cross-platform DirectShow alternatives for real life graph

Today I have such graph. I run it on windows

_{(source: narod.ru)}

I need some easy crossplatform DirectShow like alternative where to reconstruct such graph will not be a hard task.

Where can I get such alternative? *(and If you can presenta way to reconstruct such graph in It It would be grate!)

BTW: By crossplatform I mean Linux Mac and Windows compatible, By using开发者_StackOverflow社区 SampleGrabber I ment I need to be able to get data from that step of graph from my programm and I use VirtualCamera from here soundmorning.com/download.php

The possibility is GStreamer, the concept is similar to DirectShow. Probably every Linux distribution does contain it. Windows binaries can be found here, Mac OS X here.

The Phonon library, which is part of Qt, may be worth a look. It's a wrapper around DirectShow on Windows, Quicktime on Mac and GStreamer on Linux and has an architecture that's fairly similar to the filtergraphs of DirectShow.
