aes67-web-monitor

AES67-web-monitor is a micro service that allows you to monitor your LAN AES67 streams on your browser. This means ... on your phone too !

How To

First get code

git clone https://github.com/nicolassturmel/aes67-web-monitor
cd aes67-web-monitor

then the dependencies

npm i

Then just run

sudo node --experimental-worker server.js

Once on the webpage, choose an interface to discover from and wait for SAP to do its magic

Why root ?

The PTP ports are bellow 1024 and require root privileges to be openned

What port is the webserver ?

The webserver is on port 8067

What about the RTP indicator ?

This indicator has 3 parts, left, center and right.

• Left shows the delay, narrow means a tight delay (packet arrives when it should), wide means a high delay. Mean in black, local max in green absolute max in red. If black is narrow and green is wide, this means a high delay variance.
• Right give the same information on inter packet time (time between packet processing)
• Center is just a color indicator. Black: no stream, green: ok, orange: uncertain, red: outside AES67 specs

So:

• symmetrical narrow streams are typically local, fpga generated, streams
• asymmetrical, wide on the left, are streams with a clock offset etc...

Help needed

• Improve stability
• Accomodate to more than two channels
• Have different metering (LUFS...)
