I am skeptical of any locally hosted media streaming setup, since I once got a NAS device hacked about a decade ago. Checked the logs and there was shady connections in it. Not sure what vuln they were using, but all my media was exposed to the public facing Internet, which was embarrassing.
Now I just pass files into VLC and watch them at my leisure. Secure NAS is a hard problem, and there’s plenty of articles over the years that talk about NAS systems getting hacked. Even though vendors claim the devices will be secure, there’s no way of knowing, and once it can talk to the public facing Internet, assume all the contents are up for grabs.
