Message.parseError

Extracts the GError and debug string from the GstMessage. The values returned in the output arguments are copies; the caller must free them when done.

Typical usage of this function might be:

...
  switch (GST_MESSAGE_TYPE (msg)) {
    case GST_MESSAGE_ERROR: {
      GError *err = NULL;
      gchar *dbg_info = NULL;

      gst_message_parse_error (msg, &err, &dbg_info);
      g_printerr ("ERROR from element %s: %s\n",
          GST_OBJECT_NAME (msg->src), err->message);
      g_printerr ("Debugging info: %s\n", (dbg_info) ? dbg_info : "none");
      g_error_free (err);
      g_free (dbg_info);
      break;
    }
    ...
  }
  ...
