Hi, Have you tried from the new repository: ?  <a href="http://cgit.freedesktop.org/gstreamer/gst-plugins-gl/">http://cgit.freedesktop.org/gstreamer/gst-plugins-gl/</a> (because there was recently a fix which is not in the <a href="http://diracvideo.org">diracvideo.org</a> repository (which is now turned off)) Can you run in a terminal: set GST_GL_WINDOWS_DEBUG=1 set GST_GL_SHADER_DEBUG=1 gdb gst-launch-0.10 run --gst-debug=glupload:5 --gst-debug=gldisplay:5  videotestsrc !  glimagesink then type:  bt when the SIGSEGV happens. (bt for backtrace) and give the whole log of this test. Sincerely Julien <div class="gmail_quote">2009/2/11 Alex Ugarte <<a href="mailto:augarte@vicomtech.org">augarte@vicomtech.org</a>> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Hi, today I have downloaded and compiled the opengl plugins from the git repository in a PC with Debian Lenny and it worked Ok. This evening I have tried to do the same process in another computer, also with Debian Lenny, but in this case for AMD64 architecture. In this case, when executing a test pipeline or the cube test application, I get a segmentation fault. I cannot assure 100% that both systems are equal (but for that little detail of the number of bits), but I have installed them both in the las two days, and more or less with the same packages. These are the test pipelines I hav tried: gst-launch-0.10  --gst-debug=glupload:5 --gst-debug=gldisplay:5  videotestsrc !  glupload ! fakesink gst-launch-0.10  --gst-debug=glupload:5 --gst-debug=gldisplay:5  videotestsrc !  glimagesink (At the end of the mail the log output). I have been looking into the code and the segmentation fault happens in gstdisplay.c, in method gst_gl_display_init_upload, which is called from gst_gl_upload_set_caps and in gst_glimage_sink_render. More exactely the  SIGSEGV happens when calling gst_gl_window_send_message. Has anyone managed to use the opengl plugins in an amd64 system? Thanks and great job these plugins (and gstreamer in general).
