Argus stability on Orin NX

carolina.trejos · July 19, 2023, 4:31pm

Hi,
We are working with an Orin NX JP 5.1.1 on a custom carrier board, streaming from two sensors 3840x2160@30fps, and we have two different setups, one that uses GMSL2 and another one that connects the sensors directly through MIPI. We are currently facing an issue on both setups in which sometimes (~ 1/15 times) when streaming using nvarguscamerasrc after power up, the following error happens.

Opening in BLOCKING MODE 
Pipeline is live and does not need PREROLL ...

We have seen this issue with different GStreamer pipelines and with an app that uses libargus directly. We also don’t suspect this being an issue with the driver or the sensor because v4l2 doesn’t show the same failure to stream after boot.

Any suggestions on what might be going on?

The problem only show while open two sensor simultaneously?

Thanks

Hi ShaneCCC,

No, we have seen this issue even when streaming from just one sensor.

ShaneCCC · July 20, 2023, 6:16pm

Did you boost the clocks to try?
Modify the control function like exposure/frame rate to dummy function to confirm it those control function cause the problem.

Hi @ShaneCCC,
I have been working with @carolina.trejos on this issue. We are seeing the following error constantly:

Error generated. gstnvarguscamerasrc.cpp, threadExecute:694 NvBufSurfaceFromFd Failed.

I started looking into gstnvarguscamerasrc.cpp to review what causes this issue and noticed there are 2 causes for the error triggering (NULL pointer of NvBufSurface or function returns -1).
To further track down what is the issue, I added more debug messages and now am seeing that the error is triggering because the NvBufSurfaceFromFd function returns -1.

What could cause this?

jafeth.garcia · July 20, 2023, 10:48pm

Modify the control function like exposure/frame rate

I applied this change for future testing

Did you boost the clocks to try?

Boosting clocks still showed the previously sent error.

ShaneCCC · July 21, 2023, 4:13am

Please also use the argus_camera to clarify the problem too.

Thanks

jafeth.garcia · July 21, 2023, 11:13pm

@ShaneCCC I will test that as well.

We took a deeper look into the nvarguscamerasrc and noticed that the error is being triggered by the waitForEvents method:

event_status = iEventProvider_ptr->waitForEvents(src->queue.get(), WAIT_FOR_EVENT_TIMEOUT);
g_mutex_unlock(&src->queue_lock);
if (iEventQueue_ptr->getSize() == 0)
{
      g_mutex_lock (&src->argus_buffers_queue_lock);
      src->stop_requested = TRUE;
      g_mutex_unlock (&src->argus_buffers_queue_lock);
      break;
}

This was returning a 0 size pointer. I added loop here to allow for retrying this. It has been successful in retrying. However, after this stream still failed. I tried restarting nvargus-daemon after all software reboots in case it is an issue with the daemon. The error I see after this is:

Setting pipeline to PAUSED ...

Pipeline is live and does not need PREROLL ...

Which is triggered here:

if (iEvent->getEventType() == EVENT_TYPE_ERROR)
    {
      if (src->stop_requested == TRUE  || src->timeout_complete == TRUE)
        break;

      src->argus_in_error = TRUE;
      const IEventError* iEventError = interface_cast<const IEventError>(event);
      Argus::Status argusStatus = iEventError->getStatus();
      error = g_error_new_literal (domain, argusStatus, getStatusString(argusStatus));
      GstMessage *message = gst_message_new_error (GST_OBJECT(src), error, "Argus Error Status");
      gst_element_post_message (GST_ELEMENT_CAST(src), message);
      g_mutex_lock (&src->argus_buffers_queue_lock);
      src->stop_requested = TRUE;
      g_mutex_unlock (&src->argus_buffers_queue_lock);
      break;
    }

This error has no further description other than Argus Error Status. Since this is not a helpful description we are unable to know how this can be solved. What can cause this issue to be triggered? Are there any other recommended steps based on this new information?

jafeth.garcia · July 25, 2023, 3:27pm

This is the retry cycle I added to avoid the waitForEvents returning an empty queue:

   while (event_retry < 5) {
      event_status = iEventProvider_ptr->waitForEvents(src->queue.get(), WAIT_FOR_EVENT_TIMEOUT);
      if (event_status == STATUS_OK) {
        GST_ARGUS_PRINT("Event status ok\n");
      } else {
        GST_ARGUS_PRINT("Event status NOT ok\n");
      }
      if (iEventQueue_ptr->getSize() == 0) {
        event_retry++;
        GST_ARGUS_PRINT("Waiting for events\n"); 
      } else {
        break;
      } 
   }

Its a bit crude but the retry is working. The Argus status is seen to be CANCELLED. Is there a way to enable capture once Argus is in this CANCELLED state?

ShaneCCC · July 26, 2023, 7:53am

Try to terminal the APP and restart new one if get CANCLLED state.

carolina.trejos · July 28, 2023, 2:00am

To reproduce this issue all we do is run a GStreamer pipeline right after booting up the board. We have seen this happen even with the simplest possible pipeline.

gst-launch-1.0 nvarguscamerasrc sensor-id=0 ! fpsdisplaysink text-overlay=0 video-sink=fakesink sync=0 -v

ShaneCCC · July 28, 2023, 2:43am

Do you run the gst-launch-1.0 manually or have any script?

carolina.trejos · July 28, 2023, 2:56am

Both ways, we have seen it fail when running it manually, but we also created a service that ran a script with the pipeline after the argus daemon service.

ShaneCCC · July 28, 2023, 2:59am

Could you share the service and script here.
Also could you start the nvargus-daemon by infinitetimeout to try.

sudo service nvargus-daemon stop
sudo enableCamInfiniteTimeout=1 nvargus-daemon

Thanks

ShaneCCC · July 31, 2023, 8:37am

@carolina.trejos
We can’t repo the problem with imx219 on Orin NX.
Below is the reproduce step.

Reboot device
When device boot up and run below command quickly:
$ gst-launch-1.0 nvarguscamerasrc sensor-id=0 ! fpsdisplaysink text-overlay=0 video-sink=fakesink sync=0 -v
→ Repeat steps 1-2 30 times, no issue.

carolina.trejos · August 1, 2023, 1:26am

What resolution and framerate are you using with the imx219?

ShaneCCC · August 1, 2023, 5:28am

1080p@30fps

Thanks

Is there any way you could test with a higher resolution? We are using 3840x2160, any chance that could affect?
Also, we have tested with the enableCamInfiniteTimeout enabled, and the issue still happens.

ShaneCCC · August 16, 2023, 7:19am

@carolina.trejos
We still unable to repo the problem with 3280x2464@21 sensor mode.
Do you have any other module for clarifying?

carolina.trejos · August 17, 2023, 10:00pm

Unfortunately we don’t have another module, but we are testing JP 5.1.2 to see if the issue persists.
