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 https://github.com/apache/cordova-plugin-file 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!
