Camera Streaming Issue in orin nx

atman.shah · June 5, 2025, 6:22am

Hi,
I am using Jetson_Linux_R35.4.1_aarch64.

I am using a custom carrier board based on the Orin NX, with two cameras connected. When Board is up for the first time and I start streaming using nv3dsink it is working properly as expected.

But after that if I use filesink and record the video using the WIFI it is recording the video but the video i am getting is black/corrupted screen.

And this is strange but when I use filesink first and record the video using WIFI it will record properly and I can see the video after downloading it.. But just after that If I run the nv3dsink it’ll stream the black/corrupted video.

Also I have noticed that the video file size of when recorded properly and can see the video is much larger then the video file size of when black/corrupted size.

Now if i use nv3dsink multiple times on the board it is giving properly visible camera stream. but if i use nv3dsink and use fakesink after that there will be no crash in fakesink but after that if i use nv3dsink again it will start streaming of cameras but it’ll be blank/corrupted screen.

Now the main thing here is whenever I face this issue and reboot the board it’ll Be capturing video properly whether using nv3dsink or filesink… But only for the first iteration.

So my basic question here is what is the issue with filesink or fakesink that if i run them it is making the cameras corrupted.. Because if i run nv3dsink multiple times it’ll work properly. but just after filesink or fakesink that too will stop working.

We are not observing any crashes.. just the black/corrupted video stream.

I have also tried this command “sudo systemctl restart nvargus-daemon.service” But the observations remains same…

Thanks.

What’s the command for those steps?

atman.shah · June 5, 2025, 7:30am

For nv3dsink we use “gst-launch-1.0 -v nvarguscamerasrc sensor-id=0 sensor-mode=0 ! nv3dsinksink”
for fakesink “gst-launch-1.0 -v nvarguscamerasrc sensor-id=0 sensor-mode=0 ! fakesink”
and for filesink " gst-launch-1.0 -v nvarguscamerasrc sensor-id=0 sensor-mode=0 ! ‘video/x-raw(memory:NVMM),format=NV12,width=3856,height=2180’ ! nvv4l2h264enc bitrate=8000000 ! h264parse ! qtmux ! filesink location=case_6_9.mp4 -e"

Sensor id 0 & 1 we are running in parellel…

ShaneCCC · June 5, 2025, 7:55am

You can have & to add another camera by different sensor-id to launch multiple cameras.
For example

gst-launch-1.0 -v nvarguscamerasrc sensor-id=0 sensor-mode=0 ! fakesink & gst-launch-1.0 -v nvarguscamerasrc sensor-id=1 sensor-mode=0 ! fakesink

atman.shah · June 5, 2025, 8:50am

Yes we are doing that in parallel for sensor id 0 and 1.
I have pasted only 1 sensor id command for your reference second camera id command will be the same just sensor id will be 0.

And also we are running these cameras in master slave mode… sensor id 1 is master and 0 is slave.

atman.shah · June 5, 2025, 12:26pm

The main Question for here is does fakesink or filesink cause any disruptions on GStream pipelines ?
Because we are observing such behavior here

ShaneCCC · June 5, 2025, 1:05pm

Didn’t hear this kind of case.
Maybe boost the clocks to try.

sudo su
echo 1 > /sys/kernel/debug/bpmp/debug/clk/vi/mrq_rate_locked
echo 1 > /sys/kernel/debug/bpmp/debug/clk/isp/mrq_rate_locked
echo 1 > /sys/kernel/debug/bpmp/debug/clk/nvcsi/mrq_rate_locked
echo 1 > /sys/kernel/debug/bpmp/debug/clk/emc/mrq_rate_locked
cat /sys/kernel/debug/bpmp/debug/clk/vi/max_rate |tee /sys/kernel/debug/bpmp/debug/clk/vi/rate
cat /sys/kernel/debug/bpmp/debug/clk/isp/max_rate | tee  /sys/kernel/debug/bpmp/debug/clk/isp/rate
cat /sys/kernel/debug/bpmp/debug/clk/nvcsi/max_rate | tee /sys/kernel/debug/bpmp/debug/clk/nvcsi/rate
cat /sys/kernel/debug/bpmp/debug/clk/emc/max_rate | tee /sys/kernel/debug/bpmp/debug/clk/emc/rate

atman.shah · June 6, 2025, 9:34am

I have checked using this… But there is no improvement.

atman.shah · June 6, 2025, 10:31am

If I use any sink it’ll just work for the first time only after reboot.. after that nothing is working.
Can someone confirm it is the usual behaviour of nvidia sinks or something else ?

Please Help.
Thanks.

Hi, I have some questions that might help better understand the problem

Does this issue appear when using only one camera?
Is the issue happening on both cameras at the same time?
Do you know if the camera is still sending buffers when the error happens?

You could also check if theres is something strange happening on the GStreamer pipeline if you change the debug level:

GST_DEBUG=*:4  gst-launch-1.0 -v nvarguscamerasrc sensor-id=0 sensor-mode=0 ! nv3dsinksink

ShaneCCC · June 9, 2025, 4:08am

Didn’t hear any sink would cause this kind of problem.
Do you verify the v4l2-ctl open/close stress test?

atman.shah · June 9, 2025, 6:12am

Hi, Sure I’ll try with the changed debug level that you’re suggesting.

And to answer your questions…

Does this issue appear when using only one camera?
Answer : We are using 2 cameras directly in master slave mode.
Is the issue happening on both cameras at the same time?
Answer : Yes While running them parellely
Do you know if the camera is still sending buffers when the error happens?
Answer : I am getting only these logs which I am attaching below :

Logs: these are for sensor id 0 and I am having the same logs for sensor id 1

Add queue to try.

gst-launch-1.0 -v nvarguscamerasrc sensor-id=0 sensor-mode=0 ! queue ! nv3dsink

atman.shah · June 9, 2025, 6:39am

Done this also but it didn’t work..

ShaneCCC · June 9, 2025, 6:43am

Does single camera have the problem?

atman.shah · June 9, 2025, 7:01am

No when I reboot the device both camera can stream in parallel for nv3dsink and filesink but when I end that stream and again start the stream It’ll not work It’ll show me black/corrupted screen. And we are running this in master slave mode.

ShaneCCC · June 9, 2025, 8:53am

What I want to clarify is open master only without problem?

atman.shah · June 9, 2025, 2:02pm

when we open master only it is having the same problem.

josh244 · June 10, 2025, 1:24am

Regarding the reboot issue, you can find a way to get more logs from nvargus-daemon here:

essentially following these instructions to get more logs and plugging into AI tools:

To enable logs from user-space for more details

sudo service nvargus-daemon stop
sudo su
export enableCamPclLogs=5
export enableCamScfLogs=5
/usr/sbin/nvargus-daemon

launch camera from another console

ShaneCCC · June 10, 2025, 4:06am

Verify the sensor streaming by v4l2-ctl like below to confirm the sensor control.

while 1
    v4l2-ctl -c bypass_mode=0 --stream-mmap --stream-count=100 -d /dev/video0
    v4l2-ctl -c bypass_mode=0 --stream-mmap --stream-count=100 -d /dev/video1
    sleep 2
done
