MediaggYour own catalogue
Pointing Mediagg at any public Github directory of m3u playlists.
Custom Github Directory is a provider with nothing in it until you supply the source — Any public Github directory of m3u playlists. If you keep your playlists in a repository, or know of one worth browsing, this is how Mediagg reads it.
Adding a directory
Open Add from providers on the Add subscription screen, choose Custom Github Directory, then the + for Add a github directory. It asks for The directory's address — github.com/owner/repo, or a link to a folder in one — and takes either form:
github.com/owner/repo— the whole repository- a link to a folder inside one, if only part of it is playlists
You can add more than one. The provider lists everything you have added at its top level, and any of them can be let go of later: It stops being listed here. Anything you already subscribed to from it stays.
What you will see inside
The repository's own shape is left alone. Mediagg invents no categories and reorganises nothing: directories are directories and m3u files are playlists, at every level, because there is no honest way to guess the structure of somewhere it has never seen.
Open folders until you reach a playlist, then subscribe to it.
GitHub allows 60 requests an hour. Each folder you open costs one; going back costs none. The add dialog says so before you start. The allowance is per hour and frees up on its own, so a large repository is best browsed a little at a time.
Naming
A subscription taken from here is named after the playlist and the folder above it, so that several playlists with the same file name stay tellable apart in your library. You can rename it afterwards, and clearing your rename falls back to the catalogue's own name rather than to nothing.
