how do I play mp3 file?

How can I write a script in ruby which plays mp3 file (background-music) when executed from command-line?

I tried this

run = "mplayer #{"/Users/bhushan/resume/m.mp3"} -ao sdl -vo x11 -framedrop -cache 16384 -cache-min 20/100"
system(run)

but it is not working also, above is player specific. what if user don't have mplayer installed. Id there a better way?

You can write ruby code that uses different players.

For instance, a class I use:

Rather than mplayer, one could use sox or vlc or something else.

In your example, you can always extend your code. Rather than hardcoded mplayer, you could read this from a yaml file, which you can dynamically change.

You can also try to use gstreamer via ruby-gtk directly.

But remember, ruby in itself can not play audio files.

It would be cool if someone would be able to create a pure ruby player though.

Try this way: this uses Shoes to do the magic, it's all you need i hope http://rubylearning.com/blog/2008/05/31/a-teeny-weeny-mp3-player-using-ruby-and-shoes/

#my_mp3player01.rb
Shoes.app do
  button( 'play' ){ @v.play }
  button( 'pause' ){ @v.pause }
  button( 'stop' ){ @v.stop }
  @v = video "C:/rubyprograms/mp3player/ruby.mp3"
end

I usually just do

pid = fork{ exec 'mpg123','-q', file }
