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 icecream -q --name 'radio_%Y_%m_%d' --stop 60min http://radio.com/playlist.pls BUGS
