Best way to get a list of all image & video file url's in camera roll in Android & iOS

I have been bashing my head against the whole here for a couple hours and still don’t have a great solution.

Does anyone know of the best way to a list of all photo and image url’s in Android & iOS camera roll?

All the cordova plugins that go about trying to accomplish focus on a user choosing photos, whereas I just want url’s to all files in the camera roll.

My thought here is to use potentially to move to the camera roll destination and piece through it that way.

Do you guys have any thoughts on a better solution? Thanks in advance!
