deepstream-test2_Jetson_Nano

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 !!!
