</span>It might make sense to try and condense the pipeline to the essential<br>
bits that you're trying to benchmark, e.g. something like:<br>
<br>
perf stat gst-launch-1.0 videotestsrc !<br>
video/x-raw,format=BGRx,width=1920,height=1080 ! imagefreeze ! queue !<br>
videoconvert ! video/x-raw,format=I420 ! fakesink num-buffers=1000<br>
<br>
or just<br>
<br>
time gst-launch-1.0 ...<br>
<br>
Cheers<br>
