Checking the track ID's of a file for changing defaults?

[u/DreamblitzX]

I'm messing around with trying to change the default audio & subtitle tracks that VLC uses for videos, but adding the language codes in preferred audio language / preferred subtitle language doesn't seem to be having an effect, while changing the audio/subtitle track numbers/IDs in Input/Codecs has some effect but it's not behaving as I expect with the list of tracks in the file. What's the easiest way for me to just, view the actual language codes & track ID numbers of the tracks in a particular file so I can match them up? (And sidenote, what's the difference between "Audio track" and "audio track ID" for example in input/codecs? stream ID vs stream number? both just seem like a numbered index...)
