Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson / GPU) TX2
• DeepStream Version 5.0
• JetPack Version (valid for Jetson only) 4.3
• TensorRT Version 7.1
• NVIDIA GPU Driver Version (valid for GPU only)
• Issue Type( questions, new requirements, bugs) Bugs : Deepstream pipeline crashes with “Error: gst-stream-error-quark: Internal data stream error. (1): gstbasesrc.c(3055): gst_base_src_loop (): /GstPipeline:pipeline0/GstPylonSrc:usb-cam-source:
streaming stopped, reason error (-5)”
• How to reproduce the issue ? (This is for bugs. Including which sample app is using, the configuration files content, the command line used and other details for reproducing)
• Requirement details( This is for new requirement. Including the module name-for which plugin or for which sample application, the function description) I am using Adlink NEON-2000-JT2 vision camera that has a basler camera connected to Jetson TX2 module. I am using pylonsrc gstreamer plugin to connect the camera to deepstream plugin. When I run this pipeline : gst-launch-1.0 -v pylonsrc binningv=2 binningh=2 ! fpsfilter ! nvvideoconvert ! ‘video/x-raw(memory:NVMM),format=NV12’ ! m.sink_0 nvstreammux name=m batch-size=1 width=1296 height=972 ! nvinfer config-file-path=/opt/nvidia/deepstream/deepstream-5.0/sources/deepstream_python_apps/apps/My_app/detector_config.txt ! nvtracker ll-lib-file = /opt/nvidia/deepstream/deepstream-5.0/lib/libnvds_mot_klt.so tracker-width=640 tracker-height=384 ! nvdsanalytics config-file=/opt/nvidia/deepstream/deepstream-5.0/sources/deepstream_python_apps/apps/My_app/config_nvdsanalytics.txt ! nvvideoconvert ! nvdsosd process-mode=2 display-bbox=1 ! nvegltransform ! nveglglessink sync=False . My application works for a while and crashes with following error Error: gst-stream-error-quark: Internal data stream error. (1): gstbasesrc.c(3055): gst_base_src_loop (): /GstPipeline:pipeline0/GstPylonSrc:usb-cam-source:
streaming stopped, reason error (-5).

Hi,
For further check you may make sure the camera source is stable. Please try this pipeline and see if it can run without hitting the crash:

gst-launch-1.0 -v pylonsrc binningv=2 binningh=2 ! fpsfilter ! nvvideoconvert ! ‘video/x-raw(memory:NVMM),format=NV12’ ! nvegltransform ! nveglglessink sync=0

And please try to run deepstream-app with default config file. To make sure it works fine with video file sources.

Thank you for your reply. I am not sure I understood what you mean by a stable camera source.

• deepstream-app with default config file works fine.
• I tried your suggested pipelines and i get a visual. At first attempt it carshes almost immediately with hereafter error and second and third attempt it worked for longer:
  gst-launch-1.0 -v pylonsrc binningv=2 binningh=2 ! fpsfilter ! nvvideoconvert ! ‘video/x-raw(memory:NVMM),format=NV12’ ! nvegltransform ! nveglglessink sync=0

Hi,
It looks to be an issue in the source. It looks not stable and cannot be consistently run. We suggest check with vendor for improving stability of the source.
