How do I know how to refer to plugins in a deepstream-app config file?

An example of my question in the title is that nvinfer is referred to as primarygie in a deepstream-app config text file:


There are multiple cases of this where the reference / header of the plugin in the config file is not the same as the actual name of the plugin. This creates confusion for me as I don’t know what unkown plugins are in configs I find online or in documentation, and vice versa I cannot deduce what the plugin should be called in a config file I create.

An example of the lack of clear documentation here is on the page for nvinfer. The term “primary-gie” is not mentioned anywhere!

Is there something I am missing?


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

The content of config file for deepstream-app is addressed this page and primary-gie description can be also found here: DeepStream Reference Application - deepstream-app — DeepStream 6.3 Release documentation (
You can consider “primary-gie” as a wrapper of nvinfer which is specific in deepstream-app.
