NVIDIA DeepStream study notes 26 - how deepstream measures frame delay and how long each module takes

If you want to optimize the end-to-end latency of your processing pipeline, you can use the latency measurement method in DeepStream.

To enable frame delay measurement, run the following command on the console:

export NVDS_ENABLE_LATENCY_MEASUREMENT=1

To enable delay for all plugins, run the following command on the console:

export NVDS_ENABLE_COMPONENT_LATENCY_MEASUREMENT=1

Measurement results
