My plan was to plug it in the Demux or playlist/directory.c.
Because here, we already receive all children of the directory. Instead
of dropping items that are not audio/video (see "ignore-filetypes"
option), I'll keep item slaves (srt, ac3 and co) in order to attach them
to the good input item, then I'll drop all slaves that are not attached.
The big advantage of this solution is that it doesn't add any network
That way, subtitles detection will work when browsing network
directories. Also, the application that use libvlc will be able to store
the input slaves in a db for a later use.
