Keep in mind that if the language is not set, it will be seen as unknown. Or you can do the opposite and look for ones only in a foreign lanaguage. You’ll be shown a list of language so you don’t need to know what they are, just pick them from the list.
Oh great, thanks for that…I didn’t even realize that the smart playlists were so powerful!
While I’m here, a few more questions/improvements:
I don’t see a way to filter on “Unknown”. There is a “Not Applicable” item in the language list, but it seems no “Unknown” option?
Unrelated to filtering, is there any (easy?) way to remove audio streams from a file? I have a couple that have both English and another one and it would make filtering a bit easier going forward if I could remove the non-English one where appropriate.
A minor bug, when selecting a language from the list, that language isn’t removed from the selection list so it’s hard to see which ones are already selected or not.
1 - You can’t since “unknown” is not an actual language. That’s just what Plex shows when the language field is blank. There isn’t a way to look for blanks but you can look for not something like in my example above. “Not English” will show unknown.
2 - See comment above.
3 - It doesn’t do that. Maybe try doing a few at a time only.
