What needs to be fixed? Something like:
- check for winsock2.h header (and maybe -lwsock32 / -lws2_32) in configure
- yield HAVE_WINSOCK2 or the like in config.h
- include config.h in os_support.h and be able to go through the currently 
hidden code

Actually, I've sat on this code for very long, up to the point where I need to 
check if my test program (attached) actually works and if it is the latest 

With longer tests/benchmarks, I would try the hack implemented in it. If I 
remember well, it saves a GetBitmapBits (memcpy?). For instance, in your code:

>     GetDIBits( ctx->hCaptureDC, ctx->hCaptureBitmap,
>                0, ctx->bih->biHeight, pkt->data, ctx->bih,
>                DIB_RGB_COLORS );
