Hello,
I haven't seen the whole discussion about this, but from what I understand someone is using PD, mplayer and jack for streaming to an icecast/shoutcast server.
I have used PD as a 24/7 source encoder/streamer, using mp3cast~, in the OtherSide project. This was a server that had PD running a synthesis patch which can be controlled by OSC through IRC and a bot listening on a chatroom there. It has been up for the past 3-4 months non-stop and with no maintenance within the University of Sheffield intranet.
My initial experiment was to run PD through Jack and use Darkice. I'd patch the PD outputs to the Darkice inputs, which would then stream to the Icecast server. It didn't seem to be as stable though and it was more CPU-heavy than mp3cast~. I initially tried to do that cause I wanted to use other software apart from PD, but I ended up scripting the rest of the software and get their output in PD, which would pipe the output directly to the Icecast server. I didn't use a dac~ or jack, saving a lot of CPU resources.
Any comments welcome, I'm still interested in hearing about ways other people do similar things.
Take care,
Ilias
Hi Ilias,

Sounds doable with synthesized audio.
When building a "play list" like function that handles virtually an infinite number of audio files, I think what Roman referred to as "Symbol table pollution" comes to consideration... I imagine this being unreleased memory that occurs in the course of handling file names. Is my understanding correct?

Not sure how much this adds to the conversation but... we have been using mp3cast~ to stream our radio station to 2 shoutcast servers for a few years now. Works very well. Occasionally it will cause the entire OS to hang (happens less than 1x/month with our off-campus server and never with our oncampus server) but it was more stable than darkice in our tests as well.
We use Jack for our connections. Our content scheduler is a hacked up webcalendar, which triggers the content to be played via xmms (to be replaced hopefully very soon by mplayer), then fed via jack-rack through a compressor and limiter, and then sent to Pd for streaming.
OT: but we also have a flash server/player solution which we find much more popular than our shoutcast servers, and ours is the only open-source web server I have seen actually work. It's an old version of ffserver --- since 2006 or so that app has been broken for us at least. Are there others out there?
