have you checked that the sdlshare or cluttershare examples are working on your win32 environment ? (works on mine) <div class="gmail_quote">2009/11/4 Andrey Nechypurenko <<a href="mailto:andreynech@yahoo.com">andreynech@yahoo.com</a>> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><div class="im">>>>> set GST_GL_WINDOW_DEBUG=1 >>>> before launching the pipeline, it should output some debug >>>> informations about >>>> success or failure when sharing gl contexts. >> >>Sorry for such a question, but where this output goes on >>Windows?

My self-compiled gst-launch actually generates debug > output, but my GUI application not. </div>Adding CONFIG += console in .pro file got back the stdout. So now I can see the following messages: GstGLWindow-DEBUG: WM_CREATE GstGLWindow-DEBUG: gl context created: 196608d GstGLWindow-DEBUG: failed to share opengl context 196608d with 65537d GstGLWindow-DEBUG: gl window created: 330264d GstGLWindow-DEBUG: begin loop So it seams like the problem is really with context sharing on Windows. <div><div></div><div class="h5"> ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
