But you said that gst-launch ran successfully. Were you able to run gst-inspect? If so, did it list out all the plugins?<br><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<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> gstreamer-devel-bounces+dhoyt=hoytsoft.org@lists.freedesktop.org [mailto:gstreamer-devel-bounces+dhoyt=hoytsoft.org@lists.freedesktop.org] <b>On Behalf Of </b>Dinesh Kumar<br><b>Sent:</b> Friday, August 17, 2012 5:28 AM<br><b>To:</b> gstreamer-devel@lists.freedesktop.org<br><b>Subject:</b> Re: qtgstreamer build issues - Win32<o:p></o:p></span></p></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Hi, <o:p></o:p></p><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>I have few more pointers to add<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal> -> There were some errors in my qtgstreamer build.
