str_format() does not really work here:
 - if VLM is used, it will take the meta data from the playlist,
 - if sout-keep is used, it will take the meta data from the first item,
 - if LibVLC is used, it will not get any meta data.

Furthermore, I would rather not redefine existing sout parameters to be
formatted, as it breaks backward compatibility, and makes scripting hard.

I would need the meta data in the audio output, and face a similar issue.
I guess the only clean way involve notifying the ES output when meta data
change, and from there to sout and aout.
