It might make sense to try and condense the pipeline to the essential
bits that you're trying to benchmark, e.g. something like:

perf stat gst-launch-1.0 videotestsrc !
video/x-raw,format=BGRx,width=1920,height=1080 ! imagefreeze ! queue !
videoconvert ! video/x-raw,format=I420 ! fakesink num-buffers=1000

or just

time gst-launch-1.0 ...

Cheers
