           Summary: Shared opengl context not shared correctly
    Classification: Desktop
           Product: GStreamer
           Version: 0.10.x
        OS/Version: Windows
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-gl
        AssignedTo: gstreamer-bugs at lists.sourceforge.net

     GNOME version: ---


Attempting to use the opengl context sharing feature fails if the original
opengl context has been 'used' already.

Patch below changes the arguments to wglShareLists so that the new opengl
context is used to share against the existing one:

c:\gst-plugins-gl\gst-libs\gst\gl>diff gstglwindow_win32.c
old_gstglwindow_win32.c
479c479
<         if (!wglShareLists (priv->external_gl_context, priv->gl_context))
---
>         if (!wglShareLists (priv->gl_context, priv->external_gl_context))
