<br>I would first delete the registry and try again. Look for it in C:\Users\<account>\.gstreamer-0.10\registry.i586.bin or something like that IIRC. I might also try and use the gstreamer SDK, copy the qt gstreamer plugins into the plugin folder (typically <installation dir>\lib\gstreamer-0.10\ IIRC), their dependencies to the bin\ folder, delete the registry file, and try again. That could help isolate whether the problem is your glib/gstreamer build or the qt gstreamer build.<br>
<br>But really, the fact that it’s failing on registering “GstObject” is a major problem and something doesn’t smell right.<br><br>HTH,<br>- David Hoyt<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"><u></u> <u></u></span></p>
