"Video-stream stopped!"

We are using a darknet for object detection. We have been trying to apply the weight file that we have trained in YOLOv3 to the camera for a while now.
However, when I try to run the darknet demo, I get the following error.

" Video-stream stopped!"

Our development environment is Linux, and we are trying to run the following code.

cd ~/darknet

$./darknet detector demo datasets.data yolov3-voc.cfg yolov3-voc_4000.weights “gst-launch-1.0 nvarguscamerasrc sensor_mode=0 ! ‘video/x-raw(memory:NVMM),width=3820, height=2464, framerate=21/1, format=NV12’ ! nvvidconv flip-method=0 ! ‘video/x-raw,width=1280, height=760’ ! nvvidconv ! nvegltransform ! nveglglessink -e”

I would like to know if there is any effective way to deal with this.

Hi,

Do you run the command on Nano or a Linux-based desktop?
If Nano is used, would you mind sharing the whole output log with us?

Thanks.

Hello, thanks for the reply.

We use the command on Nano.
The whole output log is following.

Hi,

gst-launch-1.0 should not be the part of the pipeline string.
Could you try if the following command works?

$./darknet detector demo datasets.data yolov3-voc.cfg yolov3-voc_4000.weights “nvarguscamerasrc sensor_mode=0 ! ‘video/x-raw(memory:NVMM),width=3820, height=2464, framerate=21/1, format=NV12’ ! nvvidconv flip-method=0 ! ‘video/x-raw,width=1280, height=760’ ! nvvidconv ! nvegltransform ! nveglglessink -e”

Thanks.

Hi!

I tried to run the code you suggested, using “coco.data” file because "datasets.data"file did not open.
However, I got the error again.

How can I solve this problem?

./darknet detector demo cfg/coco.data cfg/yolov3.cfg yolov3-tiny.weights "nvarguscamerasrc sensor_mode=0 !

The results showed that the camera device was not connected.
However, when I entered

gst-launch-1.0 nvarguscamerasrc ! nvoverlaysink

the video input from the camera was displayed on the screen.

By the way, the camera I am using is
“SainSmart IMX219 camera module, 8MP sensor for NVIDIA Jetson Nano 160 degree FoV 3280x2464 resolution, RoHS certified”.

thanks.
