Hi everyone, I am starting to read about DeepStream and I have runned the script example for “ deepstream-test 2 ” on Jetson Nano.
I have tryed to use file and rtsp such as input and i have the same error.

ERROR from element file-source: Resource not found.
Error details: gstfilesrc.c(533): gst_file_src_start (): /GstPipeline:dstest2-pipeline/GstFileSrc:file-source:
No such file “file:/opt/nvidia/deepstream/deepstream-5.0/samples/streams/cars.mp4”
Returned, stopping playback
Deleting pipeline

I have all the links for “model-file”, “proto-file”, etc for the “dstest2_pgie_config.txt”, “dstest2_sgie1_config.txt”, etc files according to Primary and Secondaries paths on Deepstream folder for the samples models.

I am interesting to know the performance for the NVTRACK in order to count the objects.

Thanks a lot !!!

Can you provide platform and software information in following format:

• Hardware Platform (Jetson / GPU)
• DeepStream Version
• JetPack Version (valid for Jetson only)
• TensorRT Version
• NVIDIA GPU Driver Version (valid for GPU only)

Are you using DeepStream python or DeepStream C/C++?
deepstream-test 2 is open source for both c/C++ and python.
Have you read README file in the folder /opt/nvidia/deepstream/deepstream-5.0/sources/apps/sample_apps/deepstream-test2(for C/C++)?
It can only accept h264 element stream local file as input.

Hi @Fiona.Chen

• Hardware Platform (Jetson / GPU) Jeston Nano

• DeepStream Version 5.0

• JetPack Version (valid for Jetson only) 4.4

• TensorRT Version 7.1.3

• NVIDIA GPU Driver Version (valid for GPU only)

—Yes, I have but I do not understand when it say “It can only accept h264 element stream local file as input.” I have tried with “file:…/xxx.mp4” “rtsp://…”

—I prefer to use Python, I have downloaded the repository and I have write the inks for the files, engine, protox, etc on each config file (dstest2_pgie_config.txt, dstest2_sgie1_config.txt, etc

—My intention is try to understand how the NVTRACKER works for count the objects detected on the scene but not for each frame, I am talking about count the objects which are on the scene since it appears until it disappears but only once.

Are you running “”?

If so, what is your command line?
The README of python deepstream-test2 is here:

You reported the “Resource not found” problem in this topic, do you want to resolve this problem?

If you have special question for “nvdstracker”, you need to create a new topic.

It is better to learn DeepStream before you start to learn DeepStream python.

Thanks @Fiona.Chen , I will take in count the advices, to be honest I am confusing because some texts recommend such as first step run the examples for learn and understand how Deepstream works.
