Writes a customizable string to a file, probably with the current song name so you can use it in an OBS text source.
I don't actually know how to install a plugin if you aren't using a portable version of DeaDBeeF. But if you are, just put the plugin file in the plugins folder and restart the game.
Edit plugin settings by going to Edit -> Preferences -> Plugins -> OBS Text File.
You can format the text however you want, but I would not recommend adding any sort of playback time, as it only updates when the song starts or stops. Here are the current options for title formatting.
Default path is probably in the DeaDBeeF folder.
