GStreamer elements performance

To measure the performance, we have used two of our GStreamer tools: GstShark and GstPerf

Jetson Xavier NX

For testing purposes, take into account the following points:

• Maximun performance mode enabled: all cores and Jetson clocks enabled.
• Jetpack 4.6
• FPS is equal to 1/processing time

In the following sections you will see the performance for each of the elements.

cudashift element

The following pipeline was used to measure processing time and FPS for an image with 4K resolution.

GST_DEBUG="GST_TRACER:7" GST_TRACERS="proctime" gst-launch-1.0 -ve v4l2src io-mode=userptr ! 'video/x-bayer, bpp=10, format=rggb' ! cudashift shift=5 ! fakesink

Measurement (Average)	Jetson Xavier NX
FPS	417
Processing time (seconds)	0.002396
