Text test source element

[iron_guitarist1987]

Sorry for being so naive, but I am still new to gstreamer, and the
development guide isn't as thorough as I would like it to be.

static GstFlowReturn
gst_text_test_src_create (GstBaseSrc * basesrc, guint64 offset,
    guint length, GstBuffer ** buffer)
{
  GstFlowReturn res;
  GstTexttestsrc *src;
  src = GST_TEXT_TEST_SRC (basesrc);
  GstBuffer *buf;
  char *data = "test string";
  
  buf = gst_buffer_new_and_alloc (sizeof(data));
  buf->data = data;
  
  buffer = buf;

  return GST_FLOW_OK;
}


I get:

$ gst-launch -v videotestsrc pattern=1 ! georeg name=s ! ffmpegcolorspace !
ximagesink texttestsrc ! s.
