Window does not appear

[padam]

Hi guys (or girls),
That how i prepare player:


loop = g_main_loop_new(NULL, FALSE);
pipeline = gst_element_factory_make("playbin2", "player");

GstCaps *caps;
pl.sink = gst_element_factory_make("appsink", "sink");
caps = gst_caps_new_simple ("video/x-raw-rgb",
                           "width", G_TYPE_INT, 384,
                           "height", G_TYPE_INT, 288,
                           "framerate", GST_TYPE_FRACTION, 25, 1,
                           "bpp", G_TYPE_INT, 16,
                           "depth", G_TYPE_INT, 16,
                           "endianness", G_TYPE_INT, G_BYTE_ORDER,
                           NULL);
gst_app_sink_set_caps(GST_APP_SINK(pl.sink), caps);
gst_caps_unref(caps);
if(pl.sink)
        gst_base_sink_set_sync(GST_BASE_SINK(pl.sink), 1);
gst_app_sink_set_drop(GST_APP_SINK(pl.sink), 1);
g_object_set(G_OBJECT(pl.pipeline), "video-sink", pl.sink, (void*)NULL);
pl.audioSink = gst_element_factory_make("gconfaudiosink", NULL);
g_object_set(G_OBJECT(pl.pipeline), "audio-sink", pl.audioSink, (void*)NULL);

I made it based on file:///C:/Documents%20and%20Settings/sartymowski/Pulpit/ZAPISANE%20STRONY/ofGstUtils_8cpp_source.html

and my thread function
void *StartMainLoop(void *threadid)
{
        GstAppSinkCallbacks gstCallbacks;
        short int i = (short int)threadid;
        pl.bFrameByFrame = 1;
        g_object_set(G_OBJECT(pl.sink), "emit-signals", FALSE, "sync", !pl.bFrameByFrame, (void*)NULL);
        if(!pl.bFrameByFrame)
        {
                //gstCallbacks.eos
               
        }
        g_main_loop_run(pl.loop);
        gst_element_set_state(GST_ELEMENT(pl.pipeline), GST_STATE_NULL);
        /*gst_object_unref(GST_OBJECT(pipeline));*/
        pthread_exit(NULL);
}

but after run main loop the windows does not appear, and i have no idea why, when i comment out this line
g_object_set(G_OBJECT(pl.pipeline), "video-sink", pl.sink, (void*)NULL);
everything is working except getting actual frame, są i need this!!!

Does anybody know what i should do? I am working on Windows XP


EDIT: Ok, i know that it was caused by appsink. When i replaced it by audovideosink everything works just fin, but still i do not know why.

This is a local document you are referencing.

Which is expected, as you replaced the video sink with a sink that will
pass the frames to your application.

What is that you want to do? If you need the frames in your application
*and* see them on the screen, you obviously need two video sinks.
