According to the documentation of this module, this module will loop the audio file continuously while the source stream is running. By default, the module will look for sample.mp4 in the StorageDir of the running application.
I do not think it supports a live source as the audio track, and I do not think it supports audio/video synchronicity(if that is a requirement). There is nothing else built-in that supports this that I am aware of, but I have read a few consultants say they can achieve this
