Is it possible to stream video from NAS ?

I have writte an App that streams videos over HTTP, everything works fine. Instead of streaming over HTTP I would like to stream directly from my NAS drive, is that possible. On my macOS I would use NetFSMountURLSync to mount my NAS and the stream the files. Sadly NetFSMountURLSync is not available on tvOS. So how do I mount my NAS drive in order to access the files ?
