I am trying to realize the pipeline below with the c-code snippet further
below. The problem I have is with the src.vidsrc property or parameter. My
effort is obviously wrong, so how do one fix this ?

gst-launch-1.0 -v -e uvch264src name=src auto-start=true
initial-bitrate=2000000 src.vidsrc !
video/x-h264,width=640,height=480,framerate=30/1 ! rtph264pay ! udpsink
host= port=5000

  videosrc        = gst_element_factory_make ("uvch264src",      "encoder");
  capsfilter      = gst_element_factory_make ("capsfilter",    
  videopayload    = gst_element_factory_make ("rtph264pay",     "payload");

  capsfiltercaps =
  g_object_set (G_OBJECT(capsfilter), "caps",  capsfiltercaps, NULL);

  g_object_set(G_OBJECT(videosrc), "name", "src", NULL);
  g_object_set(G_OBJECT(videosrc), "auto-start", true, NULL);
  g_object_set(G_OBJECT(videosrc), "initial-bitrate", 2000000, NULL);
  g_object_set(G_OBJECT(videosrc), "*src.vidsrc*", NULL, NULL); // ?????
