Most "OF" way to play movie from camera roll, iOS

I’m looking to play a movie from the camera roll of an iOS device, and am looking for the most OF-centric way to do that.

It looks like that OF “loadMovie” is setup for getting a movie from the bundle of the app.

What is the ideal way to load from camera roll?

It looks like OF’s image picker is setup only for still images, not video. The play for video, is set for internal bundle.

So where is the appropriate place to extend function? Should a new method be added to ofxiOSVideoPlayer?

I don’t necessarily have to have an interface for picking the movie, either. It would be handy to just be able to pass a given index number from the camera roll file list to a “loadMovie/play” method.

Has anyone already crossed this bridge, or have any thoughts? Thanks.
