Network overview

Be it on localhost, a LAN or over the internet, Mosaic might use some required or optional network protocols.
Here's a list of used network features and their protocol / port usage; probably useful for privacy purposes, security, debugging, or network administration.

Summary

Identifier	Required	Protocol	Port	Comment
NDI Video Input	No	??	??	Only for receiving video
Tracy	No	UDP	8089	Only for profiling Mosaic
Update Checking	No	https	80	Automatically connects on launch when internet is connected.
OSC Input	No	OSC	??	Port can be changed.

Core

• The [Update checking] mechanism contacts GitHub on launch when an internet connection is available.

Objects

• videoGrabber : [NDI Video Input] Can connect to NDI servers to receive video streams.
• oscReceiver : [OSC Input] Can receive messages from localhost or LAN.

Debugging

• [Tracy] : Uses port 8089 to send profiling data from Mosaic (client) to a Tracy server (typically the Tracy Profiler). Only for "profiling" builds. May function over LAN networks. Also announces its presence on launch (see 2.1.3-4 in the Tracy readme).
