In LiquidSoap it's possible to either preload all audio values, or to have them load each time they are requested using request.dynamic. When I attempt to use request.dynamic and load liquidSoap as a daemon it hangs when trying to process the file, but works if I use the static loading methods. Sample code follows.
Essentially it seems that when dynamic code is running in daemon mode, it gets as far as selecting the decoder and hangs.
I'm running under Ubuntu 4.3.3-5ubuntu4, with LiquidSoap version 0.9.0
Static code works in all cases:
set("log.file.path", "/tmp/static.log")
output.file.mp3("/tmp/staticTest.mp3", mksafe(single("say:Hello Static World")))
Dynamic code only works when loaded directly into the shell, not when run as a daemon:
set("log.file.path", "/tmp/dynamic.log")
output.file.mp3("/tmp/dynamicTest.mp3", mksafe(request.dynamic({request.create("say:Hello dynamic world")})))
