Gstreamer Application.Init Referance DLL problem in Winform c#

I'm trying to play a video with gstream.

I have installed this programs :

• GStreamer-WinBuilds-GPL-x86-Beta04-0.10.7.msi

• GStreamer-WinBuilds-SDK-GPL-x86-Beta04-0.10.7.msi

• MinGW 32-bit and 64-bit runtime installer

I added these paths:

• Var Name : GST_PLUGIN_PATH Path: C:\Program Files (x86)\OSSBuild\GStreamer\v0.10.7\lib\gstreamer-0.10
• Var Name: OSSBUILD_GSTREAMER_DIR Path: C:\Program Files (x86)\OSSBuild\GStreamer\v0.10.7\
• Var Name: OSSBUILD_GSTREAMER_SDK_DIR Path: C:\Program Files (x86)\OSSBuild\GStreamer\v0.10.7\sdk\
• C:\Program Files (x86)\OSSBuild\GStreamer\v0.10.7\sdk\bin;
• C:\Program Files (x86)\OSSBuild\GStreamer\v0.10.7\bin;

but I get a dll error like the following

DllNotFoundException: Unable to load DLL 'libgstreamer-1.0-0.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

NOTE : I added the libgstreamer-1.0-0.dll file into the debug folder.
