Hi, i use the Jetson Orin AGX board that emulated to jetson-agx-orin-devkit-as-nano4gb. So i’d like to test encode and decode h264 with gstreamer and usb camera. My pipelines: gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw, width=1920, height=1080, format=YUY2, framerate=5/1 ! nvvidconv ! …

Hi, Please break down the pipeline and check tegrastats. To identify how much usage is used in x264enc. You may try the pipelines: $ gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw, width=1920, height=1080, format=YUY2, framerate=5/1 ! videoconvert ! video/x-raw,format=I420 ! fakesink $ g…

Can I have any way to encode h264 by gstreamer with this board? I’d like to have more encoding way. Like using cuda, chip encode, cpu, gpu. Thanks

Hi, Please try software encoder x264enc: $ gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw, width=1920, height=1080, format=YUY2, framerate=5/1 ! videoconvert ! x264enc ! h264parse ! matroskamux ! filesink location=video.mkv

Actually, I’d like to know the encoding ability of this board. but when I encode 1920x1080 5fps (using your pipeline), the average of CPU usage increases by up to 30-40%. Is the amount of number right? When I reviewed the specification of Jetson Orin Nano 4GB, I saw “1080p30 supported by 1-2 CPU …

Hi, If you need encoding function in your use-case, we would suggest use Orin or Orin NX to utilize hardware encoder.

I want to encode without a hardware encoder. Like Orin Nano, the video encoder is just supported by the software. Is there any way to do that? If using your pipelines, I think It’s not suitable for the specification “1080p30 supported by 1-2 CPU cores” because of the high CPU usage for that. Moreov…

Hi, Do you check CPU usage through tegrastats? If not, please run sudo jetson_clocks to enable CPU cores t maximum clock. And check CPU usage by running sudo tegrastats.

Yes. I checked multiple tools: sudo tegrastats, top, htop, jtop,… It showed the average of CPUs (usage): ~30% when Orin Nano encodes from camera YUYV2 to h264 files.

Hi,
This is expected since there is no hardware encoder in Orin Nano. Please refer to module data sheet for supported hardware functions:
