[PLUGIN] MPD OLED - installation & configuration plugin

[Adrii]

Hi Don_Frenk

Thanks. Most likely cava (the mpd_oled_cava process) has crashed.

I don’t know all the details of the plugin setup, but the crash may relate to using a recent version of cava, and the Volumio user that runs mpd_oled (which starts cava) does not have a home directory indicated in a way that cava can determine.

Hi Radiomanoff The static display is a symptom of installing the current version of mpd_oled (with the change to the mpd_oled service) over any previous version of mpd_oled. If this is the case, then you should be able to fix it by running the commands from the issue I linked to MPD_oled over MoOde audio rel 8.3.2 · Issue #84 · antiprism/mpd_oled · GitHub [EDIT: but use your mpd_oled options in the final command] Adrian.

Hi Radiomanoff Yes, and it can be a very small difference that stops things working. The mpd_oled update issue with the static screen on Moode is that cava (mpd_oled_cava), which is the program that calculates the spectrum, crashes when mpd_oled starts it. I am not sure of the exact origin of the issue, but the situation is that the current version of cava must be run by a user that has a home directory, indicated in an appropriate environment variable (e.g. HOME), and this isn’t set when mpd…

If this is the issue in the plugin, then this might be enough information to fix it (or provide instructions to resolve it).

Otherwise, it is difficult for me to look at anything on Volumio at the moment, but if there is no way forward on this issue then I will try to take a look.
