There are gstreamer bindings. I am not sure about their status, but IMO  
the biggest problem with gstreamer is that it is overdesigned for such  
simple tasks 😃

By the way, I think there is no need to use ‘??’.  
A simple ‘?’ should suffice.

I just compile the latest trunk with gstream for windows. Fortunately,  
the latest trunk src able to play mp3. But I get some warning  
message…Although it shows the warning but I still able to listen to  
the music.

Here is the output:  
C:\Devel\installer3\sandbox\ruby-gnome2-trunk-latest\trunk\gstreamer\sample\>ruby  
audio-player.rb xy.mp3  
OIL: ERROR liboilcpu.c 282: oil\_cpu\_i386\_kernel\_restrict\_flags():  
Operating system is not known to support SSE. Assuming it does, which  
might cause problems

Do you think this info is important for users, and is it missing on the  
wiki?

If so would you mind to do this again :)) or otherwise provide the info?  
If I have the info I can put it onto the wiki, so that windows users at  
least  
have the necessary information on the ruby-gtk wiki available

There is no binary package for the gstream yet. I compiled it myself  
using the mingw ruby. You have to download all the require dll urself  
and use mingw gcc to compile it. I only able to get the .lib file for  
gstream and has to use other tool to convert it into the gcc share  
library libxx.a file.
