Troblue searching for Brazilian Portuguese subtitles

[Blasg2]

The subtitles exist on opensubtitles, and i tried adding some variations on uosc languages config but i'm probably writing something wrong. I tried with "pt-br" just "br". How would the full line of the code be?

ps: i still want to keep searching in en, but also for brazilian portuguese. ps2: idk if this is possible but it would be cool to implement a search on mpv and right click to go to the opensubtitles link for it, so the 5 subs per day limit is a little easier to deal with.
