Why do I set a FUSE path and a media library path?
During SiaStream setup, you specify two folder paths - one for FUSE, and one for your media.
The media path
Your media lives where it lives. You don't change anything about that. Telling SiaStream where your movies and shows are lets it know what content you want to access from your media player.
The FUSE path
This is how SiaStream can actually serve that content. The FUSE mount lets your media player make a connection to the files that get uploaded to the Sia network.
