Problem with Vorbis and Theora file on Android

[doon]

I try to play audio from the video and audio file, but have strange problem
with the pads linking. Here is my code: 

G_BEGIN_DECLS
GST_PLUGIN_STATIC_DECLARE(coreelements);
GST_PLUGIN_STATIC_DECLARE(soup);
GST_PLUGIN_STATIC_DECLARE(opensles);
GST_PLUGIN_STATIC_DECLARE(playback);
GST_PLUGIN_STATIC_DECLARE(ogg);
GST_PLUGIN_STATIC_DECLARE(vorbis);
GST_PLUGIN_STATIC_DECLARE(audioconvert);
GST_PLUGIN_STATIC_DECLARE(theora);
GST_PLUGIN_STATIC_DECLARE(videoconvert);
GST_PLUGIN_STATIC_DECLARE(videotestsrc);
GST_PLUGIN_STATIC_DECLARE(opengl);
G_END_DECLS

void MainWindow::play(){
    GST_PLUGIN_STATIC_REGISTER(coreelements);
    GST_PLUGIN_STATIC_REGISTER(soup);
    GST_PLUGIN_STATIC_REGISTER(opensles);
    GST_PLUGIN_STATIC_REGISTER(playback);
    GST_PLUGIN_STATIC_REGISTER(ogg);
    GST_PLUGIN_STATIC_REGISTER(vorbis);
    GST_PLUGIN_STATIC_REGISTER(audioconvert);
    GST_PLUGIN_STATIC_REGISTER(theora);
    GST_PLUGIN_STATIC_REGISTER(videoconvert);
    GST_PLUGIN_STATIC_REGISTER(videotestsrc);
    GST_PLUGIN_STATIC_REGISTER(opengl);

    gst_init(NULL, NULL);
    play_vorbis_audio();
}

GstElement *pipeline;
void on_pad_added(GstElement *element, GstPad *pad, gpointer data) {

    GstElement* audioelem = ((GstElement **)data)[0];

    GstCaps *caps = gst_pad_get_current_caps(pad);
    GstStructure* str = gst_caps_get_structure(caps, 0);

    if (g_strrstr(gst_structure_get_name(str), "audio")) {
        gst_caps_unref(caps);

        GstPad* sinkpad = gst_element_get_static_pad(audioelem, "sink");
        if (gst_pad_link(pad, sinkpad) != 0)
        {
            qDebug("link audio error: \n");
        }

        gst_object_unref(sinkpad);

        gst_element_set_state(pipeline, GST_STATE_PLAYING);
    }

}
void play_vorbis_audio() {

    GstElement *httpsrc, *demux, *dec, *audioconvert, *audiosink;
    GMainLoop *loop = g_main_loop_new(NULL, FALSE);

    pipeline = gst_pipeline_new("pipeline");

    httpsrc = gst_element_factory_make("souphttpsrc", "httpsrc");
    demux = gst_element_factory_make("oggdemux", "demux");
    dec = gst_element_factory_make("vorbisdec", "dec");
    audioconvert = gst_element_factory_make("audioconvert", "audioconvert");
    audiosink = gst_element_factory_make("openslessink", "audiosink");

    g_object_set(G_OBJECT(httpsrc), "location",
"http://docs.gstreamer.com/media/sintel_trailer-368p.ogv", NULL);
    GstCaps *caps1 = gst_caps_new_simple("application/ogg", NULL);

    gst_bin_add_many(GST_BIN(pipeline), httpsrc, demux, dec, audioconvert,
audiosink, NULL);
    gst_element_link_filtered(httpsrc, demux, caps1);
    gst_element_link_many(dec, audioconvert, audiosink, NULL);

    GstElement *convert_array[2];
    convert_array[0] = dec;

    g_signal_connect(demux, "pad-added", G_CALLBACK(on_pad_added),
convert_array);

    gst_element_set_state(pipeline, GST_STATE_PLAYING);
    g_main_loop_run(loop);
}

This pipeline works fine on Ubuntu, problem occurs on Android.
If I use uri with ogv video(Theora) and audio(Vorbis) than I get this
GST_DEBUG without audio playback(of course now I need only audio, without
Theora):

But if I use uri with only audio(Vorbis) all works fine. 
So, what is the problem and how can I solve it?
