Car stereo track info problem

Postby vluser29 » 20 Jan 2023 01:00

This problem persists across many versions of VLC, multiple versions of iOS, and two cars--each having a different protocol (USB/Bluetooth). The behavior is the same. I don't think there's a reason that the car is incapable of displaying text given to it by the phone's operating system; Other apps like audible send their info correctly on every track change, automatic or manual changes.

Here is the behavior:
Tapping on a track of my phone screen manually, always works, updating the car's track info.
When 'next track' button is pressed, either on phone screen or using car controls; the audio track successfully switches and the screen of the car indicates a new track with a pop-up, but the screen of the car still reads the same data as before, same title/artist/same filename(if no metadata was present on last track). It even keeps its place in time of the track(my car shows track time)--example: if I press next at 04:22 of 6:28, it will play the next track starting at 4:23 of 6:28(next track is not 6:28 long), with the previous data showing and keeps rolling.
If I press back to restart the current track, it now indicates the correct track info correctly, just as if I had manually selected it/tapped on the track.
If I press back again immediately to switch to a previous track, there is no update on track info--the same error as if I had pressed 'next track' button.
If track changes automatically after one track runs out, and another begins, the same error occurs, as if I had pressed 'next track'.
All this behavior is the same with shuffle on or off.

Version 3.3.12 of VLC
(app store indicates my version as up-to-date)

Also, I can produce the error above, so that it shows different metadata on the car display than the current audio track, then switch apps and hit 'play' on audible, so that the car shows text for the current chapter on Audible, then switch back to VLC, pressing the 'play' button, and it resumes the audio track, and continues to show the mismatched metadata. Again this behavior continues until I restart a track, or tap on a track.
From this I infer, that it can't be the OS which is just holding on to bad metadata. The OS switches to Audible, gets its metadata from that, then switches back to VLC, and gets fresh metadata from VLC. VLC is the one actively supplying the wrong metadata to the OS, which gets sent to the car.
