Hi,
I found a snippet of code which works not exactly what I after but it
works. Mind you once started Ctrl "C" does not cease the application,
had to kill the process.
Initial tests
I can get the graphics to display ok but have lost audio from the
stream itself
see below for possible explanation. Log file attached.
#!/usr/bin/liquidsoap
# Define a Log file to monitor output
set("log.file.path","./soslug_alsa.log")
# Not used but this would define audio file to record a stream
recording = "soslug_jack.mp3"
# Define the stream input source
stream = mksafe(audio_to_stereo(input.alsa()))
# Define the icecast oput format etc..
output.icecast(%mp3(bitrate=128),
host = "soslug.org", port = 8008,
user = "<username>", password = "<password>", mount = "soslug_alsa.mp3",
description = "Liquid Soap application Streaming by Southend on
Sea Linux User Group",
url = "http://soslug.org:8008/soslug_alsa.mp3";,
stream)
# This portion of the code does indeed supply the graphics however it
also kills # the stream test indicate that the graphic display itself
is intermittent
# speeding up and slowing down. I am guessing it is output.dummy which
might be # the problem here. Either I need to move the output.dummy to
after output.file or incorporate visu.volume into output.file and drop
output.dummy altogether. I will try these tomorrow.
output.dummy(visu.volume(smooth_add(special=delay(3.,blank(duration=4.)),normal=stream)))
# Defines output format for stream to be recorded
output.file(%mp3(bitrate=192), recording,
fallible=true,
on_stop=shutdown, stream)
