Hello everybody,

I’m running Iris for a while and I will never thank enough @jaedb for it. And the Mopidy team of course.  
Actually, I’m sticking with the 3.61.1 version, because of more recent versions are using snapserver 0.26 which is still not deployed in the Debian 11 stable.

But to prepare myself when it will be, I dropped Iris and Snapserver in a vm to do some preventive troubleshooting. And if I managed to get a snap stream working, I can’t figure out how to show metadata in the output panels.

In 3.61.1, I’m using the `control_url` directive pointing to my FQDN in /etc/snapserver.conf and everything works smoothly. With snapserver 0.26, we must now use the `controlscript=meta_mpd.py` instead, but it seems not working out of the box.

My mopidy config :

What I get in the Iris output panel :

Although I am debug logging snapserver, I don’t have any clue about what to do to make it behave like in 3.61.1 :

Thanks for you reading,

Snapserver’s new `controlscript` now takes a more complete approach for what Iris was doing. In `3.61.1`, Iris maintained metadata updates and pushed these to the Snapserver’s `meta` attribute. Now, however, the API Iris used was deprecated in favour of `controlscript`.

Long story short, the next Snapserver release will bundle a Mopidy-tailored `mopidy_meta.py`. This will take care of most setups out-of-the-box. You’ll just need to update your stream to `controlscript=mopidy_meta.py` and you’ll be back in business. You can read more about this here: [meta\_mpd.py loses stable connection with MPD · Issue #997 · badaix/snapcast · GitHub](https://github.com/badaix/snapcast/issues/997)

If you simply cannot wait, download [`mopidy_meta.py`](https://github.com/badaix/snapcast/blob/develop/server/etc/plug-ins/meta_mopidy.py) and use it with the current version of Snapserver.

Thanks @jaedb, then I’ll just wait, my 3.61.1 setup is still perfectly functionnal at the moment.
