问题
I now installed gstreamer 1.0 from gstreamer.freedesktop.org and going through their tutorial here :http://gstreamer.freedesktop.org/data/doc/gstreamer/head/manual/html/section-elements-create.html I am facing a problem though ,my gst_element_factory_make() calls are failing and I think it is the pluggin path problem as suggested here: Gstreamer : gst_element_factory_make() : always fail and return NULL : Qt5 but I can't find a plugin directory in my gstreamer install directory .Can anyone suggest how I can get those plugins so I can set the path?Do I need to download them separately? (A link would be helpful if any) .I am new to gstreamer and multimedia programming in general ,I apologize if this is obvious.
Thank you for your time.

I don't know where does the plugins got installed for your system (windows, right?). You can search for the folder that has the plugin libs. Search for libgstplayback.so/.dll or libgstcoreelements.so/.dll and you should find it. It is likely under the folder you selected for installation but I don't know what is the default.
Then just use the GST_PLUGIN_PATH environment variable to point to that and run your application.
