Re: [Banshee-List] GskScreen and glib value on gstreamer#

[olivier dufour <olivier duff gmail com>]

found the issue.

It come from the fact that gstreamer have a small glib binding and gtk too.

Screen need to be used from Gstreamer# GLib for Video stuff but it come from gtk# Glib binding.

its have not the same namespace. So we have Screen ctor with GLib.Value as parameter but not a ctor with Gst.GLib.Value as parameter.

So:

1) Why we have 2 bindings for GLib...�

2) Can we switch to gtk GLib binding from Gtk in Gstreamer# ?

I have try to set my own Screen in Gstreamer#.

So I need a bit of explaination to know why we have this situation to know how get further...

Hello,

I have an issue with video feature in gst# backend because of an exception:

This exception comming from the fact that GdkScreen is not registered in Glib Type.

In fact gstreamer bring some GLib type with it but not the one from Gdk and do not want to make gstreamer inherit from gdk sharp binding to have Screen.
