How to load a DS filter without registering

[lol_123]

Does anyone know how to load a DS filter directly and bypass the usual registry-based filter enumeration?
Built-in is not counted.

Thanks, -L

What exactly do you mean by 'load'? Since this is avisynth forum, I assume you might want to use it for decompressing a video - to do that you'd have to create your own plugin (copying directshowsource is probably easiest) with the code to load the filter. It's not terribly hard, but you'll have to know C++ to do it.

IGraphBuilder* gb;
IBaseFilter* example;

CoCreateInstance(CLSID_FilterGraphNoThread, 0, CLSCTX_INPROC_SERVER, IID_IGraphBuilder, (void**)&gb);

example = new filter(); // Create instance of interesting filter

gb->AddFilter(example, L"Example");The red code is where you need to work some magic like loading the .DLL and getting the filters create entry point and calling it appropriatly.

Thanks IanB, actually what i am trying to do is to make minimal change to current MPC archetecture, and make MPC load codecs without registing them.

That is something that MPC already is able to do...
...and is totally unrelated to AviSynth.

mplayerc.exe /filter "filtername"

(See MPC Help menu, command-line switches)
