This is from my T420 Thinkpad on Linux. The only significant input I can think is my RTT to the server.

There've always been (a majority of) broadcasters that had seconds to half minute (!) delays. Very few understood, or even today understand, how to tune every single touchpoint (including what's safe to do, and what one must not do.)
Having an ultra low latency “video toaster” / broadcast mixer is a critical piece for sure.
For us the motivations to work on this started with "backstage feeds" synced with live TV that needed to look simultaneous to the home cable viewer (think World Wrestling Entertainment) as well as Wall Street calls that needed to be (perceptually) in sync with dial-ins. And of course, Times Square NYE ball drops!
In reality, almost nothing matters that way. For vast majority of content, the viewer is consuming only your stream, without some more real time channel at the same time. In most cases, the viewer cares far more about visual quality than the delay.
I hope if more broadcasters (technical and non-technical) realize what is possible they will ask for it more!

Agree! I think it is that way because you can't have intimate/interactive streams yet. When it becomes possible I hope to see more streaming to smaller/more connected audiences.
An HLS stream is so simple to set up with passable performance that few other protocols can compete.
We push technical advance until it hits a cliff in returns. We will never get there. There will be no 10 million mile drivetrain in a car. There will be no multi-generational fridge. There will be no house that withstands a tornado.
Software feels like it should be different because it's "free", but really any advance beyond the cliff is a great gift and not something to take for granted.
Even live news has large a large latency with remote interviews. Some of them are so bad it's uncomfortable watching the anchor have the patience to wait for a response before stepping on the remote feed.
Some streaming services are 30 seconds plus behind OTA, at that level twitter and half a dozen news apps have pushed the fact the goal went in while the ball is still in the other half.
It made the dream of ‘co-streaming’ available to home users and not just those with hardware/pro setups.
