On_metadata() calls its function directly in the main thread, so a long system() call can potentially create some lag in streaming. A simple solution is to add a at the end of the command so the shell will execute it in the background. Otherwise, a more general solution would be to schedule a task to be ran in the task threads -- without doing it explicitly, the parameters about the queues won't change anything. -- David -- Jean-Francois Mauguit - j...@radionomy.com CTO - www.radionomy.com -- Enter the BlackBerry Developer Challenge This is your chance to win up to $100,000 in prizes!

Ok. I would like to try to reproduce.. Could you try to send me in a private mail a sequence of songs that do not work ? I was wondering if my input2 = on_metadata(fun (meta) - system(curl http://something.radionomy.com/something.cfm?string= ^fluxid^,^quote(meta[album])),input2) before my icecast output could be the cause of some mix problems ? In fact this http request takes less than one second. Should I use set (scheduler.fast_queues,1) to avoid the problem ? Hmmm.. I don't think this can be the cause of the issue, but I could be wrong..

Re: [Savonet-users] Mix Problems
Hello, I found the prob in our test environment, it was due to false mix points. After fixing that, the conservative=true works perfectly ! Thanks for the help, it solved an old problem here ;-) Jef On 07 Jul 2009, at 12:36, Romain Beauxis wrote: Le mardi 07 juillet 2009 10:36:53, Jean-Francois Mauguit a écrit : Hello, Hi !

What we have found is that the problem occurs often when short songs are played. For example, on radios with song - jingle - song - jingle - ... there is almost no mix. So I presumed I made something wrong in the liq :-) Here is our crossfade definition def our_crossfade(~start_next,~fade_in,~fade_out,s) s = fade.in(duration=fade_in,s) s = fade.out(duration=fade_out,s) fader = fun (a,b) - add(normalize=false,[b,a]) cross(duration=start_next,minimum = -1.0,fader, s) end input2=our_crossfade(start_next=6.0,fade_in=3.0,fade_out=3.0, input) Value for start_next, fade_in and fade_out comes from the annotate and are right. One other question concerning the same problem. What happen if we have 3 files playing at the same time ? File 1 start_next = 120, fade_out 120 File 2 (duration = 140), start_next = 50, fade out = 50 File 3 fade_in = 50 So 120 s before the end of file 1 we start playing file 2 and 90 seconds later we start playing file 3 but file 1 is not yet ended. There can indeed be some issues with the remaining time, in particular since this is an estimated value. However, the crossfade have a conservative option. Using this option, the data needed for the crossfade is buffered in advance at the beginning of each track. Did you try with this option ?
