Hi,
Please try attachment on r32.2.1. It is verified by adding prob callback to the sample

static GQuark gst_buffer_metadata_quark = 0;
typedef struct AuxBufferData {
  gint64 frame_num;
  gint64 timestamp;
} AuxData;
static GstPadProbeReturn
nvargus_src_pad_buffer_probe (GstPad * pad, GstPadProbeInfo * info,
    gpointer u_data)
{
    AuxData *meta = NULL;
    GstBuffer *buf = (GstBuffer *) info->data;
    gst_buffer_metadata_quark = g_quark_from_static_string ("GstBufferMetaData");
    meta = (AuxData *) gst_mini_object_get_qdata (GST_MINI_OBJECT_CAST (buf),
							   gst_buffer_metadata_quark);

   printf(">>> Gstreamer:Frame #%lu : Timestamp: %lu\n", meta->frame_num, meta->timestamp);
   return GST_PAD_PROBE_OK;
}

GstElement* src = gst_bin_get_by_name(GST_BIN(gst_pipeline), "mysource");
GstPad *src_pad = gst_element_get_static_pad (src, "src");
gst_pad_add_probe (src_pad, GST_PAD_PROBE_TYPE_BUFFER,
    nvargus_src_pad_buffer_probe, NULL, NULL);
