TL;DR

This section is organized as follows:

• i.MX95 Performance
• i.MX8MP Performance

i.MX95 Platform

Benchmarking

Instruments:

• CPU: top command
• RAM: top command
• GstPERF: perf plugin

Replicate the Results

The following pipelines were used to measure the performance.

gst-launch-1.0 v4l2src device=/dev/video6 ! video/x-raw,format=YUY2,width=1920,height=1080,framerate=30/1 ! queue ! imxvideoconvert_g2d ! qtoverlay qml=utils/security/main_security.qml ! perf print-cpu-load=true ! queue ! fakesink sync=false

Summary

The following table summarize the results.

Resolution	CPU (%)	RAM (MB)	RAM (%)	FPS
1920x1080	7.401	195.181	2.536	30.018

i.MX8MP Platform

CPU usage

Taking the following pipelines as reference:

gst-launch-1.0 v4l2src device=/dev/video1 ! "video/x-raw,width=${W},height=${H},framerate=30/1" ! imxvideoconvert_g2d ! qtoverlay ! perf print-cpu-load=1 ! fakesink

Results

	720p	1080p	4K
Max Framerate (fps)	81.4	38.2	-
CPU(%)	2.7	4.3	-
RAM(MiB)	40	65.2	-
