Gstreamer RTSP src element name

[rajvik]

I am trying to link audio and video queue's using rtspsrc element property
name. The pipeline is: 
*gst-launch-1.0 rtspsrc location="rtsp://<file path>"  latency=0 name=demux
demux. ! queue !  rtpmp4gdepay ! aacparse ! avdec_aac !  audioconvert !
audioresample ! autoaudiosink demux. ! queue ! rtph264depay ! h264parse !
omxh264dec ! videoconvert ! videoscale ! video/x-raw,width=176, height=144 !
ximagesink*

I could create the value of name element using 
*g_object_set(source, "name", "demux", NULL);*
But I am not able to link audio and video queues hence create. Following is
the part of code:

*audio bin*
       audio = gst_bin_new ("audiobin");
        audioQueue = gst_element_factory_make ("queue", "audio-queue");
        audioDepay = gst_element_factory_make ("rtpmp4gdepay",
"audio-depayer");
        audioParse = gst_element_factory_make ("aacparse", "audio-parser");
        audioDecode = gst_element_factory_make ("avdec_aac",
"audio-decoder");
        audioConvert = gst_element_factory_make ("audioconvert", "aconv");
        audioResample = gst_element_factory_make ("audioresample",
"audio-resample");
        audioSink = gst_element_factory_make ("autoaudiosink", "audiosink");

*video bin*
        video  = gst_bin_new ("videobin");
        videoQueue = gst_element_factory_make ("queue", "video-queue");
        videoDepay= gst_element_factory_make ("rtph264depay",
"video-depayer");
        videoParser = gst_element_factory_make ("h264parse",
"video-parser");
        videoDecode = gst_element_factory_make ("omxh264dec",
"video-decoder");
        videoConvert = gst_element_factory_make("videoconvert", "convert");
        videoScale = gst_element_factory_make("videoscale", "video-scale");
        videoSink = gst_element_factory_make("ximagesink", "video-sink");
        capsFilter = gst_caps_new_simple("video/x-raw",
                        "width", G_TYPE_INT, 176,
                        "height", G_TYPE_INT, 144,
                        NULL);

*Linking procedure*

     /*Linking filter element to videoScale and videoSink */
        link_ok = gst_element_link_filtered(videoScale,videoSink,
capsFilter);
        gst_caps_unref (capsFilter);
        if (!link_ok) {
                g_warning ("Failed to link element1 and element2!");
        }
        /* Linking video elements internally */
        if (!gst_element_link_many(videoQueue, videoDepay, videoParser,
videoDecode, videoConvert, NULL))
        {
                g_printerr("Cannot link videoDepay and videoParser \n");
                return 0;
        }
        if (!gst_element_link_many(audioQueue, audioDepay, audioParse,
audioDecode, audioConvert, audioResample, audioSink, NULL))
        {
                g_printerr("Cannot link audioDepay and audioParse \n");
                return 0;
        }

*Help is highly appreciated*
