Hi Cris, 2012/5/18 Chris Rimmer <[email protected]>: > I'm building a highly dynamic streaming system using Liquidsoap, so that the > sources are built and populated with requests dynamically.

So what I did is add a callback URL as metadata on the request and > then do http.get on this URL as follows: > > callback_timeout=5.0 > > def track_notification(m) = > callback_url = m["callback_url"] > if string.length(callback_url) > 0 then > print("Callback to #{callback_url}") > ignore(http.get(timeout=callback_timeout,callback_url)) > end > end > > and when I build the source I call on_track to attach track_notification as > a callback.

This is a great and timely catch! It will get fixed very soon.. BTW: I have also been working on a json-based liquidsoap controler, there: https://github.com/savonet/liquidsoap-controler And a corresponding nodeJS module there: https://github.com/savonet/node-liquidsoap This is still relatively experimental code but perhaps it could give you ideas.. It does not have track callbacks yet tho..
