I have fallen in love with the ATV's new "aerial" screensavers and wanted to find something similar. However, everything I could find only used still images. So I signed up to become a developer but after looking around for a bit, I still don't see a way to use a video stream inside a screensaver.
Is it possible to have a handful of 5 minute videos loop in a screensaver? If not, are there any real reasons why it's not allowed?
Sorry, to clarify my use of screensaver... I am packaging screensaver functionality as an app. It may help to think of using video in a Roku application but it can resemble a screensaver. It needs to be manually invoked however and that may not fit your use case.
