I found that when appsink and nvtracker are together, this problem occurs. When I set the status to NULL, the log will get stuck here, when I delete nvtracker and exit normally

[NvMultiObjectTracker] De-initialized

xxing · August 13, 2024, 12:10pm

Can I get some help

yuweiw · August 14, 2024, 2:40am

Could you try to use fakesink to test that?

xxing · August 14, 2024, 2:44am

fakesink, everything is normal

xxing · August 14, 2024, 5:36am

I found this
When there is an appsink in the pipeline and the status is set to NULL, the nvtracker will get stuck here

#miscdatabufmanager.cpp:348
void TrackerMiscDataManager::deInit() {
  if (m_IntentionallyEmpty) {
    return;
  }

  std::unique_lock<std::mutex> lock(m_Mutex);
  while (!isQueueFull()) {
   *m_Cond.wait(lock); // block this
  }
  while (!m_FreeQueue.empty()) {
    NvTrackerMiscDataBuffer *pBuffer = m_FreeQueue.front();
    m_FreeQueue.pop();

    releasePastFrame(pBuffer);
    releaseReid(pBuffer);
    releaseTerminatedTracks(pBuffer);
    releaseShadowTracks(pBuffer);

    delete pBuffer;
  }
  m_BufferSet.clear();
}

It seems that GstMiniObject will not be truly released
I tried to mark the return_nvtracker_offer meta function, but it won’t be called in the pipeline where appsink exists

#nvtracker_proc.cpp:1454
  GstNvTrackerMiscDataObject *pGstObj = new GstNvTrackerMiscDataObject;
  pGstObj->misc_data_buffer = pMiscDataBuf;
  pGstObj->misc_data_manager = &miscDataMgr;

  gst_mini_object_init (GST_MINI_OBJECT (pGstObj), 0, G_TYPE_POINTER,
    NULL, NULL, return_nvtracker_buffer_meta);
  updatePastFrameMeta(batchList, pGstObj, procParams);
  updateBatchReidMeta(pGstObj, procParams);
  updateTerminatedTrackMeta(pGstObj, procParams);
  updateShadowTrackMeta(pGstObj, procParams);

    gst_print("NvTrackerProc::updateUserMeta2 end\n");
  /** mini_obj_ref number is alreadt 1 after initialization, so descrease by 1 here. */
  gst_mini_object_unref (GST_MINI_OBJECT(pGstObj));

yuweiw · August 15, 2024, 2:02am

It is possible that the last gstbuffer in your appsink is not released correctly. So the pGstObj cannot unref correctly. We’ll investigate this issue.

yuweiw · August 21, 2024, 7:24am

Hi @xxing , could you try to modify the source code like belows and have a try?
sources\gst-plugins\gst-nvtracker\gstnvtracker.cpp

static gboolean gst_nv_tracker_stop (GstBaseTransform * btrans)
{
  return TRUE;
}

static void gst_nv_tracker_finalize (GObject * object)
{
  GstNvTracker *nvtracker = GST_NVTRACKER (object);

  /** De-init the low-level threads and plugin */
  nvtracker->trackerIface->deInit();

  /** Terminate the output loop
   * Note: This needs to be done AFTER plugin deInit() process
   * so that all the pending buffers can be returned properly
   */
  nvtracker->running = FALSE;

  if (nvtracker->output_loop) {
    g_thread_join(nvtracker->output_loop);
  }
  nvtracker->output_loop = NULL;

  delete nvtracker->trackerIface;
  nvtracker->trackerIface = NULL;
  if (nvtracker->trackerConfig.trackerLibFile != NULL) {
      g_free(nvtracker->trackerConfig.trackerLibFile);
      nvtracker->trackerConfig.trackerLibFile = NULL;
  }

  if (nvtracker->trackerConfig.trackerConfigFileList != NULL) {
      g_free(nvtracker->trackerConfig.trackerConfigFileList);
      nvtracker->trackerConfig.trackerConfigFileList = NULL;
  }
  for(auto it=nvtracker->trackerConfig.trackerConfigFilePerSubBatch.begin();
      it!=nvtracker->trackerConfig.trackerConfigFilePerSubBatch.end(); it++)
  {
    it->clear();
  }
  nvtracker->trackerConfig.trackerConfigFilePerSubBatch.clear();

  if (nvtracker->trackerConfig.gstName != NULL) {
      g_free(nvtracker->trackerConfig.gstName);
      nvtracker->trackerConfig.gstName = NULL;
  }

  for(auto it=nvtracker->trackerConfig.subBatchesConfig.begin(); it!=nvtracker->trackerConfig.subBatchesConfig.end(); it++)
  {
    it->clear();
  }
  nvtracker->trackerConfig.subBatchesConfig.clear();
  nvtracker->trackerConfig.subBatchSizes.clear();

  g_cond_clear(&nvtracker->eventCondition);
  g_mutex_clear(&nvtracker->eventLock);
  G_OBJECT_CLASS (parent_class)->finalize (object);
}

cd sources\gst-plugins\gst-nvtracker\
make
make install

I am currently using a probe to retrieve metadata, and the issue has been resolved. However, the bugs in appsink and nvtracker should not have been fixed yet. I will test them with the code you provided later when I have time. Now I have a new problem. When I try to repeatedly restart and create the pipeline and destroy it, the memory grows and never decreases. I don’t know what’s going on

xxing · August 22, 2024, 5:43am

Can you tell me how to properly destroy the pipeline

yuweiw · August 22, 2024, 5:59am

About the new issue, you can file a new topic. For the convenience of others to refer to, we try to ensure that a topic only focuses on one related issue. Thanks

xxing · August 22, 2024, 6:27am

Okay, thank you very much.
