What's the problem? Describe what went wrong.

Filing a feature request, not a bug

What steps will reproduce the problem?

In a dolphin netplay room (the window where you see info about the connection and can up the buffer and whatnot before starting a game)
we are able to Assign Controller Ports for reach player in the room.

When we set a controller port for one or several of these players to "none" they can still watch the netplay session/matches being played without affecting the people who are actually playing.

We've been using this recently to livestream some matches and sessions but there is one issue:
The gameplay feed of the people who have their controller port set to "none" aren't entirely synced up.
From our testing so far it seems that the people actually playing the matches are always way ahead (as expected)
but one "none" port viewer/player will always be behind or ahead of the other "none" port viewers/players

This means that although we really want to, we are currently unable to do live commentary over other people's matches.

I'm not entirely sure how the entire none port system works or how the gameplay feed is streamed to the none ports but it would be great if there was some way to sync it up since based on our initial testing the differences are at least 8 seconds.

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

Tested in 5.0-321, 5.8.7 (Ishiiruka) and the latest 5.0 developer build

Is the issue present in the latest stable version?

Yes

If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)

If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible. Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too. For more information on how to use the fifoplayer, please check here: https://wiki.dolphin-emu.org/index.php?title=FifoPlayer

What are your PC specifications? (CPU, GPU, Operating System, more)

OC'd 3570k, Radeon HD7950, 16GB DDR4 RAM, samsung 830 SSD

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)
