Does vpuenc_h264 uses hardware encoding? how?

I'm using i.MX8M Plus EVK board. Does vpuenc_h264 uses hardware encoding in below example of gstreamer?

#gst-launch-1.0 videotestsrc num-buffers=300 ! video/x-raw,width=1920,height=1080,format=YUY2 ! queue ! vpuenc_h264 ! filesink location=output.h264

Hi @joanxie ,

Thanks for your response.

Yes this does work. My question was does vpuenc_h264 uses actual hardware available in board for encoding? or it is software encoding with gstreamer.

this uses HW(vpu) encoder
