Library performance
The library has two major components: the hardware-accelerated graphical rendering done by OpenGL and the web rendering engine done by Webkit GTK. In the following section, you will find the performance for the library separated into these two sections.
Graphical Rendering by OpenGL
In this section, we present results about the performance of HTML Overlay tested in the following setup:
- Board: NVIDIA Jetson Xavier NX
- Jetpack: 5.1
All the packages and dependencies are retrieved from the default APT repositories.
The following table shows the CPU usage, GPU usage, processing time and FPS.

- Note: When on mode 20W+Jetson Clocks the frequency of operation is 1.4 GHz and for 10w+Desktop mode the frequency of operation is 1.9 GHz. This is shown for the measurements for processing time in each mode.
- Note: There is no GPU consumption since we are using a flag that disables the use of GPU for WebkitGTK.

GStreamer plugin performance
The plugin was tested with an example overlay and a camera, using a Jetson Xavier NX with Jetpack 5.1.1. The measurements were taken with the following pipeline, using gst-perf:
gst-launch-1.0 -ve nvarguscamerasrc num-buffers=300 ! "video/x-raw(memory:NVMM),height=$H,width=$W,framerate=30/1" ! nvvidconv flip-method=2 ! queue ! htmloverlay url="http://0.0.0.0:8000/overlay.html" enable-js=true web-refresh-rate=10 ! perf ! queue ! nvvidconv ! xvimagesink
