VLC displaying wrong album art
Currently using VLC 3.0.11 on Windows 10, Android 9 and Mac OS X.
As explained in VLC Forum there are an VLC issue related to art displaying. You can read it here https://forum.videolan.org/viewtopic.php?f=2&t=79717&start=75
After reading all the posts i get this conclusion:
1: If you edit your tags and covers with another tagger usually they will get embeded on the file.\ 2: If you start VLC and drop a group of files to the playlist, first it will create a hidden folder in Users/Your User/appdata/roaming/VLC/art/arturl with all the highres images named "art" in as many folders as files you dropped. Those folders use some algorithm to be named unique but we need to now the tags and order VLC uses to create the name of each folder.\ 3: When you save the playlist another folder is created with the short version of the images distributed by artists, etc.\ 4: I presume that this process has the intention to accelerate the reading of graphic metadata the next time you play the list.\ 5: If you next change the metadata of that files probably VLC will not actualize the current data stored (sometimes because that file comes from another source and windows prevents the system to do it as I discoverd in some of them).\ 6: The solution pointed here is to show hidden folders in windows, search for the folder "art" mentioned, delete it and empty the trust. This will force VLC to recreate the new data (you will need to drop all you files again (just pray to get only one playlist).\ 7: There is a bug here again (this is not mentioned by some people here because they didn't find the case) ...this is when you get different "Artist" but the same "Track name" or the same "Artist". The result in this case is that you will get the first created cover for both songs with the same image, independently of the "Artist".\ 8: So for me the solution exposed here is a temporary and incomplete workaround for the problem.\ 9: The solution may be to rewrite the algorithm employed to asingn the name of the folders data of VLC. May be it's looking recursively in the present metadata of the files to generate the name by "Artist" "Track Title" and probably "Album Title" if present (that's the reason of some people get solved when changed this label data) in the short version of the covers but in the folder "arturl" it is asociating the cover with "Track Title" and then "Artist". You can make the experiment with two different tracks with the same title or fifferent groups with the same name as I did.\ 10: Hope to see a new version to resolve this bugs, they are very annoying.
