Re: gtkmm and Gstreamer 1.0

[Flavio Danesse <fdanesse gmail com>]

videooverlay.h actually not in the path of gstreamermm

Yes, I have installed, using ubuntu 13.04

You have to install gstreamermm library at first.

Unfortunately the example does not work.

g++ -o player main.cpp player_window.cpp `pkg-config gtkmm-3.0 gstreamermm-0.10 --cflags --libs`

In file included from main.cpp:29:0:

player_window.h:50:3: error: ‘PadProbeReturn’ en el espacio de nombres ‘Gst’ no nombra un tipo

player_window.cpp:36:38: error fatal: gstreamermm/videooverlay.h: No existe el archivo o el directorio

compilación terminada.

Thanks, this is what I wanted. 

#ifdef GDK_WINDOWING_X11

  m_x_window_id = GDK_WINDOW_XID(m_video_area.get_window()->gobj());

#endif

#ifdef GDK_WINDOWING_WIN32

  m_x_window_id = GDK_WINDOW_HWND(m_video_area.get_window()->gobj());

#endif

There: https://git.gnome.org/browse/gstreamermm/tree/examples/media_player_gtkmm you can find complete example of video player using gstreamermm and gtkmm. It should be easy to write the same using gstreamer.
In generally, when you're using gtkmm, I recommend you to use gstreamermm wrapper instead of gstreamer library.

Sorry for my ignorance, but can not get it to work. 

this: 

# include <gdkmm/window.h> 

int xid_parent = GDK_WINDOW_XWINDOW(drawing.get_window()); 

Returns GDK_WINDOW_XWINDOW is not defined 

On the other hand, I do not understand your example: 

XID xid_parent = GDK_WINDOW_XWINDOW xid_parent (wnd); 

Because XID It is not a data type.

Hello Flavio,

I did not do this, but it seems that you need XID of the GtkWindow. Internet provides with the following solution:

GdkWindow* wnd = ...;
XID xid_parent = GDK_WINDOW_XWINDOW(wnd);

Here is the short description of the macros: http://developer.gimp.org/api/2.0/gdk/gdk-X-Window-System-Interaction.html#GDK-WINDOW-XWINDOW:CAPS

Kind regards,
Vest

Hello, I'm new to the list and today I would like ask a question. 

I am migrating an application made in python with gtk 3 and Gstreamer 1.0 and can not find how to do this in gtkmm: 

xid = self.drawing_area.get_property ('window'). get_xid () 

Note: 

self.drawing_area is an instance of gtk.DrawingArea 

self.drawing_area.get_property ('window') is a Gdk.Window
