Prototyping and testing a mobile app with access to camera

I'm just overwhelmed with the plethora of ways to create prototypes, yet I can't find one to do what I want.

click on an image, video plays, then open device's camera

Simple eh? The only way I found to create such a prototype is Form, by Relativewave but sadly, it's discontinued, bought out and killed by Google. The current version only works on mac and I don't have a mac at work. I really like the block programming way and node presentation way of doing things with Form, though I'm not much of an expert to have strong preferences.

Any help appreciate, thanks.
