Another reason is that we need to be able to decide the "sout" string
to use for each file of the playlist we're trying to play as the
device only supports some codec and containers. The "input-prepare"
string callback was refused, partly because it could be called in
chains and in any order and thus possibly breaking badly. With this
renderer we have a single one that is designed just for that.
