Is it possible to create ffdshow filters?

[trbarry]

Occasionally there have been some ideas for filters that seemed it would be nice to run under ffdshow. But a year or so ago I got the source and had trouble building it. It required Unix'ish things like cygwin and mingw that did not like me and were incompatible with some of my other Windows development under Win/Me and VS6.

So I would really prefer to not be rebuilding ffdshow at all.

Is there any interface to just add standalone filters, similar to what is possible in Avsynth or DScaler? Without compiling or linking all of ffdshow?

If so, is it documented anywhere?

ffdshow can use DScaler filter. In the configuration dialogue you have a submenu to load DScaler dll...

Ishan -

Thanks. I'll look into that.

But I want to be able to change the output size, and I'm not sure there's a way to do that with a DScaler filter. But maybe.

There's functionality for AVISynth chains too. If you want to increase the size you have to enter the wanted size in the Resize field and set the resize method to Null. It will just adjust the canvas to the appropriate size and you can then resize with your filter. I know it's clumsy but at least it works.

That would do it. You are saying I can just run Avisynth filters under ffdshow now somehow, right?

I'll see if I can figure out how that works.

Pretty straightforward :confused:
