This page shows GstCUDA performance profiling.


Glass to glass latency

This wiki contains the glass to glass latency measurements results of GstCUDA simple capture and display pipelines on a TX2. It contains the results for all the possible GstCUDA (cudafilter and cudamux) configurations and uses cases.

All the measurements were taken using the TX2 on the high-performance mode by running the following commands: 

sudo nvpmodel -m 0 #Reboot after running it, so changes can take effect.
reboot
sudo ~/jetson_clocks

Jetpack 3.3 - IMX274 camera 4K@60fps glass to glass latency

Simple Capture to Display pipeline (without GstCUDA)

This measurement should be used as a reference to compare the glass to glass latency of the below pipelines with GstCUDA.
