Caught SIGSEGV Jetson NX

[arun-kumark]

Describe the bug I am trying to execute the simple pipeline gst-launch-1.0 pylonsrc cam::ExposureTime=20000 cam::Gain=10.3 ! "video/x-raw,width=640,height=480,framerate=10/1,format=GRAY8" ! videoconvert ! autovideosink

As a result, I see the following SIGSEGV arun@arun:~/DeepStream-Yolo$ gst-launch-1.0 pylonsrc cam::ExposureTime=20000 cam::Gain=10.3 ! "video/x-raw,width=640,height=480,framerate=10/1,format=GRAY8" ! videoconvert ! autovideosink Caught SIGSEGV Spinning. Please run 'gdb gst-launch-1.0 19979' to continue debugging, Ctrl-C to quit, or Ctrl-\ to dump core

Environment

• Camera: I am using Basler Ace2 camera

• plugin version info from gst-inspect-1.0 pylonsrc | grep -E "Descr.*pylon.*|\s+Version\s+[0-9]+"

I see that its not able to find the pylon on system, but I already installed the Pylon7 from Basler. I am not sure why this crash ! Could you please help to make the things back to normal again.

thanks Arun

do you use GigE or USB Camera? The camera parameters need to be optimized for smooth data transfer.

try to pass the following setting capture-error=skip at pylonsrc

Thanks for the suggestion SMA2016a, The problem was the network configuration in Pylon viewer and Network settings. Solving the configuration issue result in good pipeline running. I want to convert the following Pipeline in Python code for my Basler Camera. Do you have suggestion how to write and convert this pipeline to Python file? gst-launch-1.0 pylonsrc capture-error=skip pfs-location=example-file-name.pfs cam::ExposureTime=20000 cam::Gain=10.3 ! "video/x-raw(memory:NVMM)" ! videoconvert ! nvvideoconvert ! m.sink_0 nvstreammux name=m batch-size=1 width=640 height=480 ! nvinfer config-file-path=/home/arun/Documents/DeepStream-Yolo/config_infer_primary_yoloV5.txt unique-id=1 ! nvvideoconvert ! nvdsosd ! nvegltransform ! nveglglessink sync=0

thanks in advance !
