NAME
icecream - download icecast and shoutcast streams, redirecting all fetched content to stdout and/or to disk at the same time
SYNOPSIS
icecream [OPTIONS] URL [URL..]
DESCRIPTION
icecream is a lightweight, non-interactive, stream download utility. It connects to icecast and shoutcast servers or direct stream URLs,
and redirects all fetched content to stdout and/or to media files on your disk.
Listen to the stream piping the output to a stdin-capable media player. Save the stream to a named file or split it into different tracks.
It is possible to redirect the stream and save it to disk at the same time.
icecream is able to parse pls and m3u playlists, and to download mp3 and ogg direct stream URLs. If the stream is anonymous it will be
saved as 'stream-time.mp3', where time is actual timestamp.
OPTIONS
-h, --help
Print a help message describing all options
-q, --quiet
Turn off output
-v, --verbose
Be verbose
-t, --tracks
Split stream into tracks (if possible)
--name=NAME
Save the stream to file specified by NAME. Format codes starting with "%" will be replaced. See the date command for valid format
codes.
--stop=N[units]
Stop downloading the stream after N kb/mb/min/songs
--user-agent=AGENT
Set user-agent header to AGENT
--stdout
Output stream to stdout (implies -q)
--sync Turn syncing on, required for some mpeg players that read from stdin
--debug Turn on debugging outputs
EXAMPLES
Streaming to mpg123
icecream --stdout http://radio.com/playlist.pls | mpg123 -
Split stream into different tracks
icecream -t http://metal.org/radio.pls
Split stream into tracks and play with vlc at the same time
icecream -t --stdout http://streaming.com/playlist.pls | vlc file:/dev/stdin
Prepare a 74 minute CD
icecream -t --stop 74min http://trace.net/playlist.m3u
Use a filename with today's date as output
