Gstreamer RTSP src element name

[rajvik]

Hi Tim thanks for the response.

1. I have added all the elements using gst_bin_add_many:
 gst_bin_add_many(GST_BIN(audio), audioDepay, audioParse,
audioDecode,audioConvert, audioResample, audioSink, NULL);

2. I haven't used the pad-added signal, because I am confused as to how
shall I create a cb function, as I am already using rtspsrc name element.
Following the code snippet for audio and video queues:

*        /*audio bin*/*
        audio = gst_bin_get_by_name(GST_BIN(pipeline), "demux0");
        audioQueue = gst_element_factory_make ("queuea", "queuea");
        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");

*Failing here saying audio bin is NULL*
        if (!audio || !audioDepay || !audioParse || !audioConvert ||
!audioResample || !audioSink)
        {
                g_printerr("Cannot create audio elements \n");
                return 0;
        }
        gst_bin_add_many(GST_BIN(audio), audioDepay, audioParse,
audioDecode,audioConvert, audioResample, audioSink, NULL);
        if (!gst_element_link_many(audioQueue, audioDepay, audioParse,
audioDecode, audioConvert, audioResample, audioSink, NULL))
        {
                g_printerr("Cannot link audioDepay and audioParse \n");
                return 0;
        }


*        /*Video Bin */*
        video  = gst_bin_get_by_name(GST_BIN(pipeline), "demux.");;
        videoQueue = gst_element_factory_make ("queuev", "queuev");
        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);

        if (!video || !videoQueue || !videoDepay || !videoParser ||
!videoDecode || !videoConvert || !videoScale || !videoSink || !capsFilter)
        {
                g_printerr("Cannot create video elements \n");
                return 0;
        }

        /*Adding video elements to video bin */
        gst_bin_add_many(GST_BIN(video),videoQueue, videoDepay, videoParser,
videoDecode, videoConvert, videoScale, videoSink, NULL);

        /*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;
        }
