Hi,

The Ruby-GNOME2 project released Ruby-GNOME2 1.1.0.

This release fixes a crash bug by GC on Ruby 1.9. (It's not
occurred on Ruby 1.8.) If you're using Ruby-GNOME 2 on Ruby
1.9, we recommend that you update it.

Ruby/GStreamer gem for Windows is supported. If you want to
play audio and/or video data on Windows, please try it.
(You can install Ruby/GStreamer by "gem install gstreamer".)

Web:
  http://ruby-gnome2.sourceforge.jp/

Install:
  gem install gtk2

from http://www.gtk.org/

  GTK+ is a highly usable, feature rich toolkit for creating
  graphical user interfaces which boasts cross platform

Hi all,

At first, thank you for the release of Ruby-GNOME2 1.1.0.

Ruby/GStreamer gem for Windows is supported.

Great!
So, I've tried to play a .ogg file, .mp3 file and .mp4 file with the
following snippet on my Windows 7 laptop.

require 'gtk2'
require 'gst'
require 'win32api'
play_bin = Gst::ElementFactory.make('playbin2')
play_bin.uri = 'file://c/tmp/song.mp3'
play_bin.video_sink = Gst::ElementFactory.make('directdrawsink')
play_bin.bus.add_watch do |b, message|
  case message.type
  when Gst::Message::WARNING, Gst::Message::ERROR
    p message.parse
  else
    #p message.type
  end
  true
end
window = Gtk::Window.new
window.signal_connect('expose-event')do
  play_bin.video_sink.xwindow_id = Win32API.new('user32',
    'GetForegroundWindow', , 'N').call
end
window.show_all
play_bin.play
Gtk.main

I could play .ogg file and .mp4 file very well.
But unfortunately, couldn't play .mp3 file.

I asked Kou about that in ruby-list ML.
The answer is that Ruby/GStreamer gem doesn't include MAD.
Because MAD is GPL.

Just for information,

Sorry, I made a quick and wrong judgment. xx-P
Kou who is a developer of Ruby/GNOME2 said that this is a miss-packaging.
The license issue is not cleared yet. So, will delete MAD in the next
release.

Hello Mr. Asakawa et al,

What does green_shoes use for audio and video now?

Would fluendo[1] be an acceptable alternative? It's open-sourced under
the MIT license[2].

We have a problem about patent not license for MP3.
MAD is also an open source software. :slight_smile:

"Patents over the plug-in and/or Source Code" section
describes about patent.

Thanks,
