How to integrate my own program into the AppInventor?

I plan to use camcorder to record a short video, then use my own video algorithm to deal with it to get a code. Is there a method to integrate my own video processing program into the AppInventor? Or can I create my own video processing block?



The only way you can do it is with the Activity Starter...



So I need develop another APP for video processing, and development of such APP cannot be done using AppInventor, right?



That's correct.
