About this version
WebRTC performance and quality evaluation tool. It allows to validate the audio/video quality and the client CPU/memory usage when multiple connections join the same WebRTC service.
Main features:
- NodeJS application/library using Puppeteer for controlling chromium instances.
- It can be executed from sources, using the pre built Docker image or with the executables generated for each platform.
- It allows to inject custom Javascript source files that will run into the browser page context for automating some tasks (e.g. pressing a button to join a conference room).
- It allows to throttle the networking configuration, limiting the ingress/egress available bandwdith, the RTT or the packet loss %.
- It uses a patched version of chromium (see
./chromiumdirectory) that allows to disable the video decoding, lowering the CPU requirements when running multiple browser sessions. - RTC stats logging module that allows to send stats to Prometheus Pushgateway for visualization with Grafana.
- Alert rules and report generation.
The tool can be executed from sources, using the pre built executables or using the Docker image.
Using Npm:
echo '@vpalmisano:registry=https://npm.pkg.github.com' >> ~/.npmrc
npm install -g @vpalmisano/webrtcperf
# Install FFMpeg:
sudo apt install ffmpeg # Linux
# or:
brew install ffmpeg # MacOS
# Run a Jitsi test:
webrtcperf \
--url="https://meet.jit.si/${JITSI_ROOM_URL}#config.prejoinPageEnabled=false" \
--display='' \
--show-page-log=false
# Press <q> to stop.Using Docker:
docker pull ghcr.io/vpalmisano/webrtcperf
docker run -it --rm \
-v /dev/shm:/dev/shm \
ghcr.io/vpalmisano/webrtcperf \
--url="https://meet.jit.si/$JITSI_ROOM_URL#config.prejoinPageEnabled=false" \
--show-page-log=false \
--sessions=1 \
--tabs-per-session=1Stop the tool pressing q (normal browser close) or x (it will close the
process immediately).
