General
HTMLOverlay includes out of the box, an easy to use GStreamer plugin, that allows users to add overlays to media in a quick an easy manner.
GStreamer Element
Pre-requisites
NVIDIA Jetson
If you are on an NVIDIA Jetson, you may need to set the following variables
export DISPLAY=:0 export WEBKIT_DISABLE_COMPOSITING_MODE=1
htmloverlay
This element takes an RGBA video stream, renders the website and overlays the resulting website on top of the incoming video.
- Example pipeline
On Jetson platforms:
gst-launch-1.0 nvarguscamerasrc ! "video/x-raw(memory:NVMM),height=1080,width=1920,framerate=30/1" ! nvvidconv ! queue ! htmloverlay url="http://0.0.0.0:8000/fancy_overlay.html" enable-js=true web-refresh-rate=0 ! queue ! nvvidconv ! xvimagesink
On x86 platforms:
With video sources:
gst-launch-1.0 videotestsrc pattern=ball ! "video/x-raw,height=720,width=1280,framerate=30/1" ! queue ! htmloverlay url="http://0.0.0.0:8000/fancy_overlay.html" enable-js=true web-refresh-rate=0 ! queue ! videoconvert ! xvimagesink
With camera to file:
gst-launch-1.0 v4l2src num-buffers=100 ! videoconvert ! queue ! htmloverlay url="http://0.0.0.0:8000/fancy_overlay.html" enable-js=true web-refresh-rate=0 ! queue ! videoconvert ! x264enc ! h264parse ! qtmux ! filesink location=test.mp4 -v
Use cases
In this section, you can find some use cases for the HTMLOverlay. The examples were tested on a Jetson Xavier NX with Jetpack 5.1.1.
- Recording
The following pipeline records a video from a camera sensor applies the three different algorithms, and saves the video into an MP4 file.
gst-launch-1.0 -ve nvarguscamerasrc ! "video/x-raw(memory:NVMM),height=1080,width=1920,framerate=30/1" ! nvvidconv ! queue ! htmloverlay url="http://0.0.0.0:8000/fancy_overlay.html" enable-js=true web-refresh-rate=0 ! queue ! nvvidconv ! nvv4l2h264enc ! h264parse ! qtmux ! filesink location=test.mp4 -e
- Streaming
The following pipeline is an example of a streaming application with the overlay element. These pipelines use another RidgeRun product for high-performance streaming called GstRtspSink.
gst-launch-1.0 nvarguscamerasrc ! "video/x-raw(memory:NVMM),height=1080,width=1920,framerate=30/1" ! nvvidconv ! queue ! htmloverlay url="http://0.0.0.0:8000/fancy_overlay.html" enable-js=true web-refresh-rate=0 ! queue ! nvvidconv ! nvv4l2h264enc insert-sps-pps=true idrinterval=30 ! "video/x-h264,mapping=/stream1" ! rtspsink service=5000 -vvv
