latest build has the above change, had to refactor a number of things so some chance of side effects, seems ok in my setup though

I took the latest build, it resolved the issue with hamcws dependencies, so that's great! I am still seeing the player flipping to Unavailable somewhat regularly. I do see more in the logs though, so perhaps this will help:

It looks like this popped up in the logs 7 seconds after the player went unavailable.

Nevermind, at the same time, then again.

mattkhan:
The error just says the call to MCWS timed out, ie MC doesn't respond. The timeout is 5s which is a pretty long time so I guess it suggests either a network issue or a problem in MC. Anything in MC logs?

I could add some tolerance to this, like give it a few retries before falling or make the timeout longer though that may have other side effects.

mattkhan:
btw the other key point is how long it takes to recover, I think the ideal solution for working around that will vary on whether it's a brief hiccup or a prolonged one

mattkhan:
in my case, the flickering is in https://github.com/kalkih/mini-media-player and really seems like a bug in HA itself (when fresh data arrives, if the media player position hasn't updated then it tells the frontend that there's no such field so the component above reacts by removing the progress bar). I have made a change that avoids that in the latest build (0.2.2).
