So if I were to make the background playlist something like this: <playlist id="playlist_background" eof="loop"> <entry producer="producer_background"/> <entry producer="producer_background"/> <entry producer="producer_background"/> </playlist>
… is there any performance problem with doing it that way? It’s easy to compute the length of the background and the foreground, so I can just have as many entries as it takes to ensure the former is longer than the latter. ---------- jeffrey k eliasen - technologist, philosopher, agent of change blog <http://jeff.jke.net/> | linkedin <http://www.linkedin.com/pub/jeffrey-eliasen/3/a83/b76> | google+ <http://plus.google.com/+JeffreyEliasen> | facebook <http://facebook.com/jeffrey.eliasen> | twitter <http://twitter.com/jeffreyeliasen> > On Oct 21, 2015, at 16:55, Dan Dennedy <d...@dennedy.org> wrote: > > What you are trying to do - loop this until that - does not really work, > incomplete implementation.
