Setting up rtsp server using gstreamer?

[krombopulus]

Hi, I've been trying to setup an rtsp server where I send images to this
server, here is my code, 

#include <iostream>
#include <gst/rtsp-server/rtsp-server.h>
#include "opencv2/highgui.hpp"
#include "opencv2/imgproc.hpp"

using namespace std;
using namespace cv;

int main()
{
    GstRTSPServer *server;
    GstRTSPMountPoints *mounts;
    GstRTSPMediaFactory *factory;

    char port_num_Str[64] = { 0 };
    char udpsrc_pipeline[512];
    sprintf (port_num_Str, "%d", 8554);

    server = gst_rtsp_server_new ();
    g_object_set (server, "service", port_num_Str, NULL);
    mounts = gst_rtsp_server_get_mount_points (server);
    factory = gst_rtsp_media_factory_new ();

    sprintf (udpsrc_pipeline,
      "( udpsrc name=pay0 port=%d caps=\"application/x-rtp, media=video, "
      "clock-rate=90000, encoding-name=JPEG, payload=26 \" )",
      5000);

      // gst-launch-1.0 -v udpsrc port=5000 \
      // ! application/x-rtp, media=video, clock-rate=90000,
encoding-name=JPEG, payload=26 \
      // ! rtpjpegdepay \
      // ! jpegdec \
      // ! xvimagesink sync=0

    gst_rtsp_media_factory_set_launch (factory, udpsrc_pipeline);
    gst_rtsp_mount_points_add_factory (mounts, "/test", factory);
    g_object_unref (mounts);
    gst_rtsp_server_attach (server, NULL);

    VideoCapture cap("videotestsrc !
video/x-raw,format=BGR,width=640,height=480,framerate=30/1 !
appsink",CAP_GSTREAMER);

    VideoWriter out("appsrc ! videoconvert !
video/x-raw,format=YUY2,width=640,height=480,framerate=30/1 ! jpegenc !
rtpjpegpay ! udpsink host=127.0.0.1
port=5000",CAP_GSTREAMER,0,30,Size(640,480),true);

    if(!cap.isOpened() || !out.isOpened())
    {
        cout<<"VideoCapture or VideoWriter not opened"<<endl;
        exit(-1);
    }

    Mat frame;

    while(true) {

        cap.read(frame);

        if(frame.empty())
            break;

        out.write(frame);
    }
    destroyWindow("Sender");
}

When I launch a pipeline which is in comments then I can see the port
receiving my frames but however when I try to attach this pipeline to the
server I don't see any frames from the server. Any help would be
appreciated. Thanks. I've looked at the sample code for setting up rtsp
server from github, it did not work.
