The next table show the results for multiple resolutions running at standard 30 fps as the framerate and the following pipeline:
For average behavior:
gst-launch-1.0 videotestsrc is-live=1 ! "video/x-raw,width=${W},height=${H},framerate=30/1" ! videoconvert ! qtoverlay qml=gst-libs/gst/qt/main.qml ! perf print-cpu-load=1 ! fakesink
For limit behavior:
gst-launch-1.0 videotestsrc pattern=black num-buffers=1 ! "video/x-raw,width=${W},height=${H}" ! imagefreeze ! videoconvert ! qtoverlay qml=gst-libs/gst/qt/main.qml ! perf print-cpu-load=1 ! fakesink
