[Pipeline] 

data->pipeline =
      gst_parse_launch ("tcpclientsrc host=10.42.0.1 port=7001 ! avdec_h264 ! decodebin ! videoconvert ! autovideosink sync=false ", &error);
  if (error) {
    gchar *message =
        g_strdup_printf ("Unable to build pipeline: %s", error->message);
    g_clear_error (&error);
    set_ui_message (message, data);
    g_free (message);
    return NULL;
  }

Мое приложение успешно работает, но приложение показывает сообщение ("unable to build pipeline no element decodebin") Я хочу, чтобы видео в реальном времени транслировалось Пожалуйста, помогите мне, ребята.
