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 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.
