Accelerated Computing Intelligent Video Analytics DeepStream SDK

Hi,

I can find only Deepstream v1.5 for Tegra platform, is there any plan to release DS2.0 for Tegra(TX2)?

Yolo deepstream example is restricted to build only for TESLA, any particular reason for this restriction?(i am referring to deepstream-yolo tool and git tag DS2)

Thanks,
Partha

You can use the nvgstiva app on TX2 to run the yoloplugin. Instructions here - [url]https://github.com/vat-nvidia/deepstream-plugins/tree/7f27f22d674c64f4859dd1da896a43e35b0b9063#running-the-nvgstiva-app-tegra-platform-only[/url]

Hi NvCJR,

Now i am trying to build yoloplugin in the github. I am getting below error:

gstyoloplugin.h:34:30: fatal error: gstnvivameta_api.h: No such file or directory

There is discussion in this forum for similar error,

https://devtalk.nvidia.com/default/topic/1043648/building-nvyolo-plugin/

Based on the suggestion I have installed libgstreamer using below command

sudo apt-get install libgstreamer-plugins-base1.0-dev libgstreamer1.0-dev

And I have installed DS1.5 as well.

But still i am getting the same error, i couldn’t find gstnvivameta_api.h file anywhere.

Can you point me which package is having that header file?

Your help is much needed.

Thanks,
Partha

gstnvivameta_api.h is a file from the DS 1.5 SDK. Please check if the NVGSTIVA_APP_INSTALL_DIR variable is set to the correct path in Makefile.config file.

Hi,

when using the nvgstiva app with the sample video I get the following error

nvgstiva-app: yoloplugin_lib.cpp:59: void decodeBatchDetections(const YoloPluginCtx*, std::vector<YoloPluginOutput*>&): Assertion 'out->numObjects <= MAX_OBJECTS_PER_FRAME' failed.
Aborted (core dumped)

Any suggestions on how to fix this?

Increase this [url]https://github.com/vat-nvidia/deepstream-plugins/blob/7f27f22d674c64f4859dd1da896a43e35b0b9063/sources/lib/yoloplugin_lib.h#L38[/url] value to a higher number and recompile, install the plugin

Hi NvCJR,

Thanks for pointing out the file.

In your below post you have hinted about nvstreammux plugin for batch processing.

[url]https://devtalk.nvidia.com/default/topic/1043854/how-to-set-nvyolo-s-batch-size-/[/url]

Is this plugin available for Tegra X2(DS1.5)?

Is there any sample implementation?

Thanks,
Partha

Apologies for the confusion, we do not have a streammux component in DS1.5 for tegra.

Hi NvCJR,

Thanks for the clarification.

As per Nvidia webinar for Deepstream, DS2.0 for jetson is expected by 2nd half of 2018 but it seems it is not released yet.

Anything we can expect ? DS2.0 or DS3.0 for Jetson(TX2)???

Thanks,
Partha

Hi parthasarathy,

We’re aligning all those DeepStream SDK 3.0 on Xavier features for TX2 now, there is no firm schedule yet, but should be at the 1st half of 2019.

Thanks
