making our proprietary dll DirectX compatible
Mechi
We build cameras (HW and FW) and also the drivers, dll and GUI for
accessing and running them.
At the beginning I worked with DirectShow, building filters, etc.
Unfortunately it was too slow, so I built a simple API packaged as a
dll in order to communicate and get video frames, etc.
We still have customers, though, that want a DirectShow compatible
filter.
How can I simply/easily build a DirectShow filter using the dll?
(Much of the dll is designed after Vivek's VCam example)
To quote Tim Roberts:

Since I wrote the software (dll) and FW (in camera) I shouldn't have
to do any reverse engineering.
What would the basic commands be and how can I build a simple
DirectShow filter that can expose all the camera API?
Thanks,
