Intercepting Video

Hello, I am working on a project that involves some serious video processing to get meta-data about the video. The end result is to stream live video with meta-data to multiple clients using FMS2. But the video has to be processed first, and it cannot be done in Flash.

I have an idea about how it might work. The first step is to capture a web cam stream with my existing application, and do processing of it in C++, then stream it (plus the calculated meta-data) to FMS2. My big question is: can I stream from a non flash application to FMS2? If so... how? Is there a library or sample code I could use?

Thanks for any hints, or suggested other ways to do it.
