      • I have written a custom source filter for my application and was wondering is there a way to use the filter without having to register it. For instance if I wanted to use my application on another computer that computer does not have to have my filter registered to use it. Could I use it as a class object and not use CoCreateInstance on it Thanks

      • Hello, I've written a very simple transform filter to solve what I believe is a problem with Logitech's latest (v10.x) webcam drivers. I think my filter works fine, but seems to introduce an instability when I include it in my capture graph. Specifically: as detailed in another one of my posts , the Pause/Resume function would no longer work in my capture graph with the new Logitech drivers.
