internal data stream error- gpu coder

Hi all

I was tryin to implemment sobel edge detection function to execute as cuda code in nvidia jetson nx.

MATLAB Coder Support Package for NVIDIA Jetson and NVIDIA DRIVE Platforms User's Guide (mathworks.com)

I was referring to the above document. In 3-15 section this example was mentioned

Followed all the steps in the given docuemnt. While trying to run the application got an error in the target like "Error:Internal data stream error"

I have changed the path of the input file rhinos.avi and mentioned the same in the 'videoReaderDeploy.cu' in the build directory generated in the target hardware.

It would be helpful if I get any insights on this topic.

Thanks in Advance

Is it possible that you ran out of memory on the gpu?

Hi @Walter Roberson

No there is no possibility for the gpu to run out of memory in this case

[Walter Roberson]

Odd, most of the references I see for that particular error messages have to do with gstreamer on Linux -- not exactly an error in MATLAB or GPU itself.

[Gayathri Sankaran]

GStreamerVersion: '1.14.5'

This is the version installed in the target system

[Walter Roberson]

Are there messages about Gstreamer being output?

I see posts such as https://github.com/dusty-nv/jetson-inference/issues/461 which just might be relevant .

Thank you @Walter Roberson will look into this
