Hi there,

I'm just wondering if some development experts could give me an idea on the viability of this project...

Would it be possible to code up a wrapper for the VFW codec system that would access a DirectShow-only codec, therefore allowing access to DirectShow codecs within applications such as VirtualDub, After Effects etc?

Or is it the case that DirectShow and VFW are just so completely different and non-compatible that this is just not possible?

Thoughts much appreciated, and a decent-sized bounty on offer to any one willing to take up the challenge :)

Hi, in reality is is remarkable that such a project has not still been implemented. Actually I don't thik this is a problem at all.

We provided our clients DLL instead of DirectShow filter. Inside a DLL there was builded a graph like: Custom Src->DS Filter->Custom Dump.
Custom Src and Custom Dump were not registered filters and "DS filter" was an usual filter we wanted our DLL to reproduce a functionality of.

From the outside a developer can deal with such a DLL without
any DirectShow knowledge.

So, I think one can quite easy Implement this scheme in VFW or even DMO objects.
