Download

git clone https://github.ugent.be/dripauwe/WebRTC-client-Virtual-Wall.git

Install Google Chrome, xvfb and the certificate

run ./client_config.sh

Run test

• With fake video capture: google-chrome --no-first-run --no-default-brower-check --disable-translate --use-fake-ui-for-media-stream --use-fake-device-for-media-stream "https://server:8443"
• With fake video capture from file (only .y4m format is supported): google-chrome --no-first-run --no-default-brower-check --disable-translate --use-fake-ui-for-media-stream --use-fake-device-for-media-stream --use-file-for-fake-video-capture=soccer.y4m "https://server:8443" (I have a test video in .y4m but it's too large (2.2 GB) to put on github)
• run in headless mode: xvfb-run -a google-chrome ...
• Select a room: e.g room number 1: "https://server:8443/r/1"

WebRTC statistics

• in Chrome: go to chrome://webrtc-internals to see realtime WebRTC events and graphs

• logging to file: each second, the client logs the following bitrates:

  • googActualEncBitrate
  • googAvailableSendBandwidth

  These logs are both written to the console and a file (debugout.txt).

  • On default, this file is downloaded 10 seconds after the page is loaded. This time can be set with the parameter log_duration in seconds. E.g: https://server:8443/r/1?log_duration=60
  • It is possible to log every available statistic every second. Set parameter full_log=true in the URL

• Enable low-level logging in google-chrome: add the flags --enable-logging --v=1. The log file will be created in $HOME/.config/google-chrome/chrome_debug.log

• In Google Chrome v58, our certificate is not excepted. For a workaround:

  • sudo mkdir -p /etc/opt/chrome/policies/managed
  • sudo touch /etc/opt/chrome/policies/managed/test_policy.json
  • add the following content:

            "EnableCommonNameFallbackForLocalAnchors": true
          }
