Hi

the following sample show the D3D window not being released when the pipeline
is set to GST_STATE_NULL, thus, the pipeline cannot be set to playing again : 
{{{
#include <gst/gst.h>
#include <windows.h>

GstPipeline *pipeline = NULL;

int _tmain(int argc, _TCHAR* argv[])
{
    GError *theError;
    GMainLoop *theMaineLoop;

    SetEnvironmentVariable(L"GST_DEBUG", L"d3dvideosink:6");

    if(!gst_init_check(NULL, NULL, &theError))
    {
        printf("failed to initialize gstreamer : %s\n", theError->message);
        return -1;
    }
    pipeline = GST_PIPELINE(gst_element_factory_make("playbin", NULL));


    g_object_set(G_OBJECT(pipeline), 
        "uri", "file:///c:/DLNA_Media_Base/O-AVCTS_NA_I-04.ts",
        NULL);
    theMaineLoop = g_main_loop_new( NULL, FALSE );

    if(gst_element_set_state(GST_ELEMENT(pipeline), GST_STATE_PLAYING) ==
GST_STATE_CHANGE_FAILURE)
    {
        printf("Failed to gst_element_set_state.");
        return -1;
    }
    else
    {
        printf("sleeping for 5s\n"); // Video should be playing
        Sleep(5000);
        printf("setting pipeline to state NULL (and sleep 5s)\n"); // Window
should close but  doesn't
        gst_element_set_state(GST_ELEMENT(pipeline), GST_STATE_NULL);
        Sleep(5000);
        printf("setting pipeline to state PLAYING (and sleep 5s)\n");
        gst_element_set_state(GST_ELEMENT(pipeline), GST_STATE_PLAYING); //
Will fail playing the video again unless you manualy close the window

        printf("running main loop\n");
        g_main_loop_run(theMaineLoop);
        printf("finished running main loop\n");
    }

    gst_deinit();

    return 0;
}
}}}
