Hi all,
I am relaying a remote ogg stream with icecast, feeding it to
liquidsoap for transcoding to mp3, and then sending it out using
icecast again. I built liquidsoap (mercurial) from source few days
ago. The problem i am facing is that if there is some disruption in
the remote stream, liquidsoap starts relaying silence as expected,
however it doesnt go back to playing the remote stream once it is has
come back.
My stream is like this:
>cat stream.liq
set("log.file.path","/var/log/liquidsoap/radiomirchi.log")
set("log.file.append",false)
set("log.level",4)
set("log.stdout",false)
# Input the stream,
url = "http://user:[email protected]:8000/high.ogg";
input = mksafe(input.http(url))
output.icecast(%mp3(stereo=true, samplerate=44100, bitrate=128),
mount="/live.mp3",
host="localhost", port=8000, password="pass",
input)
A sample log when the stream failed is:
2011/08/20 08:49:50 >>> LOG START
