Hello,
On windows with old gst version, we use to put video in a
gtk window with xwindow_id:
view = Gst::ElementFactory.make(‘playbin’)
view.video_sink = Gst::ElementFactory.make(‘directdrawsink’)
handle = Win32API.new(‘user32’, ‘GetForegroundWindow’, [], ‘N’).call
view.video_sink.xwindow_id=handle
but it’s seem that from now ‘xwindow_id’ do not exist.
NOTA:
(view.video_sink.methods - Object.methods) give :
copy,gtype,type,value
(class GLib::Value)
Hi,

NOTA:
(view.video_sink.methods - Object.methods) give :copy,gtype,type,value
(class GLib::Value)
Please let me identify the problem.
I tried the following codes on Windows.
In GStreamer 0.10 (Ruby/GStreamer 1.2.6 or earlier), “directdrawsink”
exist.
gem "glib2", "1.2.6"
gem "gstreamer", "1.2.6"
require "gst"
p Gst::ElementFactory.make('directdrawsink')
#=> #<Gst::ElementDirectDrawSink:02BC1670 ptr=02C3D918>
In GStreamer 1.0 (Ruby/GStreamer 2.0.0 or later), “directdrawsink”
does not seem to exist.
gem "glib2", "2.0.2"
gem "gstreamer", "2.0.2"
require "gst"
p Gst::ElementFactory.make('directdrawsink')
#=> nil
I’m looking for a list of elements.

I’m looking for a list of elements.
here the code (i try to use d3dvideosink) :
require “gtk3”
require “gst”
Gem.loaded_specs.map {|n,g| puts " | %10s %6s " %
[g.name,g.version] }
window = Gtk::Window.new
wid=Gtk::DrawingArea.new()
wid.set_size_request(200,100)
v =Gst::ElementFactory.make('playbin')
v.video_sink = Gst::ElementFactory.make('d3dvideosink')
require('win32api');
handle = Win32API.new('user32', 'GetForegroundWindow', [], 'N').call
p window.window.methods
v.video_sink.xwindow_id(handle) # !!!!scratch!!!!
v.uri = "file:///d:/usr/local/video/avi/film3.avi"
wid.events |= ( ::Gdk::Event::Mask::BUTTON_PRESS_MASK |
::Gdk::Event:
:POINTER_MOTION_MASK |
::Gdk::Event::BUTTON_RELEASE_MASK)
wid.signal_connect(‘draw’) do |w1,e| end
window.signal_connect("destroy") {Gtk.main_quit}
window.add(wid)
window.show_all
Gtk.main
And the execution:
d:\usr\Ruby\local\Ruiby\samples>ruby v.rb
| pkg-config 1.1.4
| glib2 2.0.2
| gio2 2.0.2
| atk 2.0.2

| pango 2.0.2
| gdk_pixbuf2 2.0.2
| gdk3 2.0.2
| gtk3 2.0.2
| gobject-introspection 2.0.2
| gstreamer 2.0.2

That’s work !
Thank you.
Discovering Clutter, it’s seem very mysterious, no tutorials…
bye
Good evening.

I started to write Ruby/Clutter tutorial.

Tell me if it is difficult to understand.

Umm… The API seemed to change.
Now, there is also the following way:
require “clutter-gtk” # gem install clutter-gtk (It uses gtk3)
require “clutter-gst” # gem install clutter-gstreamer
clutter = ClutterGtk::Embed.new
stage = clutter.stage
video_texture = ClutterGst::VideoTexture.new
stage.add_child(video_texture)
video_texture.uri = “file:///d:/usr/local/video/avi/film3.avi”
video_texture.playing = true
window = Gtk::Window.new
window.signal_connect(“destroy”) {Gtk.main_quit}
window.add(clutter)
window.show_all
Gtk.main

Hi,
Regis d’Aubarede wrote in post #1121938:
Found that on wikipedia:
"
Clutter is an open source graphics library for creating
hardware-accelerated user interfaces. It relies upon OpenGL (1.4+) or
OpenGL ES (1.1 or 2.0) for rendering, can be compiled on different
platforms (X11, Wayland, Darwin and Win32) and has multiple bindings to
other languages (including Mono, Perl, Python, Ruby and Vala). It also
supports media playback using GStreamer and 2D graphics rendering using
Cairo.[4]
"If Clutter is done for performence, its usage via Ruby is it relevant ?
Umm, I don’t know much about it…
I use Gosu for graphics (smooth) animations (sprites,vectors for
games…),
Is Clutter better for that ?
Oh, Gosu is looking good. But I think that uses are different.
Gosu is for game application, and Clutter is for general desktop
application.
Clutter is able to make game application, but it will be some hard work.
If not making game application, I think that Clutter may be better than
Gosu.

Nice start !
