MPRIS Tune Publishing does not function

[Slips-PC]

Hi, I'm using psi-plus-git (as packaged on the AUR) and I cannot seem to get tune publishing to work. The button in the top right cannot be pressed, I have my PEP configuration as follows:

I am using the Clementine music player, I know this music player supports MPRIS and I know it works with tune publishing, as Gajim has no issues publishing from it. I am unsure of what is wrong.

I just tested with Clementine 1.4.0 and Psi 1.5.1618 on Ubuntu 22.04. It works well. Tested with Icecast internet radio and default settings for tune controller with just enabled "publish tunes".

so the problem needs further investigation. maybe MPRIS protocol changed or something like this. Or maybe Arch version was compiled w/o dbus support.

@Vitozz can you check on your Arch?

I do not see anything about D-Bus in PKGBUILD:
https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=psi-plus-git
And USE_DBUS option is enabled by default in cmake.

[tehnick]

PKGBUILD for clementine does not have any notes about dbus either:
https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=clementine-git
And it should be enabled if Qt5DBus library is found in the system:
https://github.com/clementine-player/Clementine/blob/master/CMakeLists.txt

Just tested mpris and clementine on my manjaro. Everything works well.

By the way, it depends on DE. Dbus service should be enabled and started.

dbus is running on my machine as i've confirmed (see below pic), and tune publishing works on Gajim through the same methods.

Of note is that the toggle tune publishing button does not function. It remains pressed constantly and clicking on it does nothing. Unsure if this is intended behavior or otherwise.

Of note is that the toggle tune publishing button does not function.

That's curious. maybe something wrong with the xmpp part. What server do you use?

[Slips-PC]

What server do you use?

I use my own personal server. Running Prosody 0.12.0, which supports XEP-0118 (Tune Publishing) natively. Tune Publishing works on the server when using Gajim, so I think that can be ruled out.

[Ri0n]

I'll check later with your version of server. But at least it works with Prosody 0.11.12.
Problems with the button may mean there is something wrong with the feature discovery.
If MPRIS xep was updated for example then maybe we need to fix something in Psi to support new standards.

[Slips-PC]

I'm currently compiling a fresh version in a vm to see if this issue occurs between machines or is relegated to mine only. Will report back.

[Slips-PC]

Just compiled a fresh version in a VM, same issue. Must be some sort of incompatibility between Prosody 0.12's implementation of MPRIS tune publishing and psi-plus?

EDIT: I did some asking around on the Prosody XMPP channels and I found this link documenting a bunch of changes to PEP and pubsub between 0.11 and 0.12. Now, I couldn't read lua if it was staring me dead in the face, but perhaps one of you folks might be able to find something important in here?

[Vitozz]

The implementation of mpris in psi fully complies with the freedesktop specification. Psi supports both protocol versions 1 and 2. Psi, when the mpris controller is on, reacts to the addition of new interfaces to the dbus. If the interface matches any version of the protocol - psi listens to events from the interface and publishes a tune based on metadata (version 2) or tags (version 1).
You can use Psi File controller to check your prosody server, Just create a file named "tune" in ~/.cache/psi (~/.cache/psi+ for Psi+) with some content.
