The stock firmware and its derivatives include a "screensaver" which shows promo images for product features (miracast, dlna etc). These images are in /system/media/screensaver/images. I can add my own images to this folder and after a reboot they become part of the screensavers carousel. However I have more images than I care to add to this folder.
I have installed photo carousel apps, but they need to be executed explicitly. I want something that auto starts.
I can't find any discussion on this topic and I figure it would be a common desire to use a media box for this purpose. So perhaps I am missing something significant. Can someone help point me in the right direction on how this can be done?
