注意的代码：

 GstElement *source, *jpegparser, *decoder;

  if (strstr(uri, "%d"))
    source = gst_element_factory_make("multifilesrc", "source");
  else
    source = gst_element_factory_make ("filesrc", "source");

  jpegparser = gst_element_factory_make ("jpegparse", "jpeg-parser");

  decoder = gst_element_factory_make ("nvv4l2decoder", "nvv4l2-decoder");

  if (!source || !jpegparser || !decoder)
  {
    g_printerr ("One element could not be created. Exiting.\n");
    return NULL;
  }
    
  g_object_set (G_OBJECT (source), "location", uri, NULL);

  const char *dot = strrchr(uri, '.');
  if ((!strcmp (dot+1, "mjpeg")) || (!strcmp (dot+1, "mjpg")))
  {
#ifdef PLATFORM_TEGRA
    g_object_set (G_OBJECT (decoder), "mjpeg", 1, NULL);
#endif
  }

  gst_bin_add_many (GST_BIN (bin), source, jpegparser, decoder, NULL);

  gst_element_link_many (source, jpegparser, decoder, NULL);
