mp3 Metadata

Hi@All
Subject: sending mp3 metadata, title etc. to car stereo

First: I'm totally lost this time and don't know where to look for, application, bluetooth, additional packages, daemons...

The situation is this:
I used a cheap Android tablet to bluetooth mp3 to my car stereo, that worked fine showing title/artist/album. This tablet died due a water spill some days ago (includind the SMD).  So I decided to use my MSI gamebook to bluetooth the music (took me days to find all my music backed up on different USB disks, how it is sometimes).
My music contains a lot of new albums, so I really would like to know the metadata information while listening, but the car stereo just shows me UNKNOWN/UNKNOWN/UNKNOWN :-(

Today I tried to use VLC instead of audacious: no change.
But I can't count out there to be a settings switch I couldn't find.

But my guess is it is connected to the bluetooth service.
However a missing library could be a reason too.

So I googled for days, but it looks as if I am the only one with this problem, means: I couldn't find anything in the net what gave me just a hint to solve the problem!

Hoping for some hints here now!
If you post a link, be so kind and add some words describing the root of the problem or solution please!

Sincerely, Joe.

PS: Sure I'm able to post some system outputs, but I'm still convinced its not connected to a special OS setting, so I didn't for now.

Re: mp3 Metadata

You're looking for a player w/ AVRCP 1.3 support or better and AVRCP malfunctions are rather common (even with android apps), often the metadata doesn't update and oc it also depends on the implementation in the cars device.
Have you considerred to just put all the music onto a 32GB/64GB usb key and plug that into the car and forget about it?

Re: mp3 Metadata

Shouldn't this be coverable by a player with mpris integration and bluez-mpris? Though not at all sure whether that works in the other direction (i.e. I know it works for player metadata when playing on a source player forwarding to the computer, not sure the other way around): https://wiki.archlinux.org/title/MPRIS#Bluetooth

OH, YES! That was my first idea! Unfortunately my "car" is a 2021 Kenworth T 680, what seems to be accept just USB-sticks from the 60's ! (or so!)

Thanks for mentioning AVRCP, something to look up!

Thanks for a hint!
I'll  have something to look up now!
I'm just very frustrated, that this "Android-Linux" does it out of the box!

Re: mp3 Metadata

If the mentioned tools won't work, then maybe you can build your own based on this example: https://github.com/bluez/bluez/blob/mas … ple-player

Thank U! mpris was the right hint!

Solution:
1. Notebook connected to stereo.
2. Player (audacious) started.
3. /usr/bin/mpris-proxy:
-----------------------------------------------
[joe@Q-ARCH ~]$ /usr/bin/mpris-proxy&
org.bluez appeared
Bluetooth Adapter /org/bluez/hci0 found
player org.mpris.MediaPlayer2.audacious at :1.61 found
Bluetooth Transport /org/bluez/hci0/dev_00_22_A0_CA_29_A3/sep1/fd1 found
-----------------------------------------------
4. Title/Artist/Album instantly shown on stereo (and the play button changes to "pause" now, while playing).

Re: mp3 Metadata

Nice to know Please mark as [SOLVED] by editing the title in your first post (and maybe use the opportunity to expand on the bluetooth to car stereo info)
