Hit the wall

I think I hit the wall now – it seems I have to do my own binding for DirectShow before I can proceed, but create a binding is not that easy especially I’m not quite familiar with either source (DirectShow) and target (Ada) areas.

I’ve tried c2ada, which seems doesn’t work well, tried dll2def and gnatdll, seems doesn’t help as DirectShow is based on COM, there are two more alternatives I can try – start from COM and use DirectShow as a regular COM component, or, find another Win32 binding which has DirectShow support.

I don’t know much about Claw or GWindow, but I just don’t like the thick binding. I will try my own binding first, and if I cannot make it, I will try to see if I can use legacy vfw to make things work, and only if that fails I will try Claw or GWindow.
