==Performance Measurement ==
 
−
The performance measurements are extracted using the specified power profile (operation mode) and with the GStreamer pipeline running in the system.
 
−
 
−
 
−
'''Operation Mode:'''
 
−
* To change the Orin AGX power profile (operation mode), please check our [https://developer.ridgerun.com/wiki/index.php/NVIDIA_Jetson_Orin/JetPack_5.0/Performance_Tuning/Tuning_Power Performance Tuning - Tuning Power] section.

−
'''CPU usage:'''
 
−
* For the CPU percentage utilization, the tegrastats utility was used as follows: <code> sudo tegrastats -readall</code>. This command shows the percentage utilization of the 12 cores that the Jetson AGX Orin devkit has. For the measurement, we compute the average over 30 samples of the utilization values for the CPU cores.
 
−
 
−
 
−
'''GPU Usage:'''
 
−
* The same procedure described for the CPU usage is done in the case of GPU percentage. As the board has 2 GPUs, 30 samples of each one are taken, and then, the average is obtained.
 
−
 
−
 
−
'''FPS:'''
 
−
* For the FPS, [https://github.com/RidgeRun/gst-perf RidgeRun's gst-perf plugin] is used. This plugin computes the FPS mean. For the measurement, we compute the average over 30 samples of the FPS mean values. The following example shows a pipeline with the perf element incorporated:
 
−
<pre>
 
−
gst-launch-1.0 -v v4l2src device=/dev/video0 ! perf ! video/x-raw,framerate=30/1,width=1280,height=720 ! nvvidconv ! 'video/x-raw(memory:NVMM), format=NV12' ! nv3dsink
 
−
</pre>
 
−
 
−
 
−
'''Latency:'''
 
−
* In the case of the Latency metric, the [https://developer.ridgerun.com/wiki/index.php?title=GstShark RidgeRun GstShark plugin] is used. For this metric, it is important to take into account that it is not a glass-to-glass measurement. GstShark provides the time needed by a buffer to travel from the source pad of the source element to the source pad of the remaining elements of the pipeline. The following pipeline shows an example of the GstShark interlatency tracer execution:
 
−
<pre>
 
−
GST_DEBUG="GST_TRACER:7" GST_TRACERS="interlatency" gst-launch-1.0 -v v4l2src device=/dev/video0 ! video/x-raw,framerate=30/1,width=1280,height=720 ! nvvidconv ! 'video/x-raw(memory:NVMM), format=NV12' ! nv3dsink

</pre>

== Remote Development ==
 
−
 
−
Often we want to run tests in a Jetson that is in another physical location. In these cases, you will need to have a display connected to the Jetson and also find out the proper value of the '''DISPLAY''' environment variable. For this, before you move to developing remotely or with someone's help at the Jetson location, connect a keyboard to the Jetson, open a terminal and  check for the '''DISPLAY''' variable executing the following command:
 
−
 
−
<pre>
 
−
echo $DISPLAY
 
−
</pre>
 
−
<noinclude>
 
−
 
−
This command will print the needed value, usually something like :0. Then you can run the GStreamer Pipeline from an SSH terminal as follows:
 
−
 
−
<pre>
 
−
DISPLAY=:0 GST_DEBUG=2 gst-launch-1.0 -v v4l2src device=/dev/video0 ! video/x-raw,framerate=30/1,width=1280,height=720 ! nvvidconv ! xvimagesink sync=true
 
−
</pre>
 
−
 
−
 
−
Make sure to replace the :0 value in the pipeline command according to your $DISPLAY environment variable. More information about accessing the Jetson Orin AGX through SSH can be found in our [[NVIDIA_Jetson_Orin/In_Board/Getting_in_Board/SSH|SSH section.]]

This section presents GStreamer pipelines to capture from MIPI CSI-2 and USB cameras and render the video to the display connected to the Orin. Key performance indicators are measured using three power profiles (operation modes). Check our GStreamer Pipelines section to find more information about how we extracted the performance metrics presented in this section.


MIPI CSI-2 Camera

For the pipelines in this section, we used the IMX477 camera.


1920x1080@30 using nv3dsink

The pipeline below captures and renders the video to the display connected to the Orin AGX using the nv3dsink element. Table 1 shows the performance metrics for this pipeline. 

gst-launch-1.0 nvarguscamerasrc ! 'video/x-raw(memory:NVMM),width=1920,height=1080,framerate=30/1,format=NV12' ! nv3dsink


Table 1: Performance of pipeline at 1920x1080@30 using nv3dsink
Operation Mode CPU (%) GPU 1 (%) GPU 2 (%) FPS latency (ms)
