[Freevo-devel] Problems creating a little plugin for freevo 1.5.3

[Gorka Olaizola]

Hello,

I'm trying to code a little plugin for playing directories recursively but
i'm very confused about how the playlist do work. My code is attached to
the message.

I simply iterate over the shuffled directories and call to Playlist.play()
in each directory, but the loop doesn't stop while the playlist is playing
and I get all the playlist playing at the same time.

Maybe is there a better way of doing this or is a way to stop execution of
the loop until the playlist finishes playing the files.

Thank you for your help.
