Hey @gh00st sorry for the delay.
I haven't used ofVideoPlayer so I wouldn't be able to tell. My problems were associated with the fact that I am using OpenFramework as a runtime component to be consumed from Xaml/C# and the lifetime of all the objects and singletons in the framework changed because of that. So I have to add a few hacks in order to used it in this way but is being very stable after that.
FreeImage was a tricky one to fix since FreeImage_DeInitialise() must be called once at the end of the application but since my Runtime Component would be instanciated and disposed several times during a session.
Did you fix the freeze thing?
As for the adding files in VS. I have no problem with that but I did have to manually edit the generated project and solution files to adapt them to my own project tree, so that might actually fixed something that you are running into. Let me know how can I help.
Cheers,
