If you use deepstream then all plugins use CUDA by default.
You can switch some plugins to the CPU version for example the encoders/decoders can be switch to the CPU alternatives. You can find those on the Gstreamer website.
And I don’t think any inference plugins (nvinfer, nvtracker, etc) can be used on CPU. You can use DLA cores for nvinfer if needed.
There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one.
Thanks
