MKV ARTIST tag handling

[RobMacNeil]

In issue #67 @paulgoulain asks if it would make sense to consider having the ACTOR tag display as Contributing artists in Windows File Explorer.

I note the response, pointing out that the Windows property is already used by the ARTIST tag.

I think that's fair enough.
I don't mind using the ARTIST tag instead of ACTOR.

However, the most common grouping level for video tags is TargetTypeValue=50 (corresponding to movie or episode level).
With Icaros activated, ARTIST TargetTypeValue=50 tags display as Album artist.

Displaying as Album artist makes sense for MKA (audio) files, where level 50 corresponds album level info.
But it doesn't really makes sense for MKV movies and episodes.

To get ARTIST tags to display as Contributing artists with MKV files you have to artificially create the tags with a TargetTypeValue below 50, such as level 30 (chapter level).

I'd like to request that Icaros makes a distinction between MKA and MKV in its handling of ARTIST tags, so that for MKV files, regardless of tag target type level, ARTIST always maps to Contributing artists (System.Music.Artist) rather than Album artist (System.Music.AlbumArtist).

That should be possible.
Matroska doesn't have a direct way to determine if a file is mkv or mka, but if we assume all matroska files that only contain audio tracks are mka, that should be good enough. Basing it on the file extension could cause issues, due to the way Windows caches the generated properties. Would that be a fine solution in your opinion?

[RobMacNeil]

That sounds good to me.

I don't really use mka files much. Though I can create a few for testing purposes, I don't think they're all that popular generally. The format hasn't really caught on compared to mkv.

Anyway, for video content, it'll be great to have the starring cast appear as Contributing artists rather than Album artist.

Great, I'll make sure it works like that in the next Icaros release.
