12. Listening to MP3's.
So, hopefully, you should now have some MP3 files ready to listen to, and have the choice of playing from file or stream.
12.1 Playing from File
Playing from file is reasonably straight-forward with all players. The only big difference is some are command-line based and some are X based.
Playing an MP3 file from file requires you to pass the mp3 file as a parameter, like so:
[dj@megajukebox]$ mpg123 /mp3_files/SampleFile.mp3 or [dj@megajukebox]$ xaudio /mp3_files/SampleFile.mp3
If you want to play a series of files, pass them in as a list:
[dj@megajukebox]$ alsaplayer /mp3_files/SampleFile1.mp3 /mp3_files/SampleFile2.mp3
To play all the tracks in a directory, just wildcard the file selected, like so:
[dj@megajukebox]$ xmms /mp3_files/*.mp3
12.2 Playing from MP3 Streams
Playing from a MP3 stream is quite easy, just replace the file with the streams url and port number:
[dj@megajukebox]$ mpg123 http://localhost:8000 or [dj@megajukebox]$ freeamp http://megajukebox:2711
12.3 Capturing MP3 Streams
A stream from a MP3 server can be captured and save locally using the following:
Streamripper
To capture an MP3 stream using streamripper, type the following:
[dj@megajukebox]$ streamripper -h megajukebox -p 8000 Press CTRL-C to stop name: Megajukebox reponse: 200 genre: Megajukebox url: http://www.megajukebox.com/ bitrate: 128 This stream contains no meta data, ripping as one large ass track 1st track ripped socket error: : Success
Here's a list of options.
[dj@megajukebox]$ streamripper
Usage: streamripper -h <host> -p <port> [-d dir]
Options:
-h <host> - Required: The host name
-p <port> - Required: The host port, typically 8000
-d <dir> - Optional: The destination directory
-l <logfile> - Optional: Output everything to a log file <logfile>
-v - Optional: Be extra verbose
-c - Optional: Don't display status counter
-q - Optional: Quiet mode, don't make mp3 files
-s - Optional: Output stream to stdout for mpg123
-n - Optional: Wait until next track before writing
-o - Optional: Create a directory with the stream name for output
wget
To save a stream using wget:
[dj@megajukebox]$ wget http://megajukebox:8000 -O download01.mp3
--13:41:41-- http://megajukebox:8000/
=> `download01.mp3'
Connecting to megajukebox:8000... connected!

12.4 Mixing
eMixer
eMixer gives you the ability to mix MP3's in a similar manner to a DJ's mixing desk.
Newer versions support 2 sound cards so you can output your mix on one card and monitor or cue the next track on another.
As usual once untaring, read the readme on how to build the package.
You will need to create a playlist of MP3 files, do this with the find command mentioned in the Streaming section.
You will need mpg123 installed before you can run eMixer.
Here are the control keys (taken from the readme)
