[BUG] Unable to properly recognize language in MKV container

[Dan64]

Hello Selur,

   In effect in MKV the language tag is: [und] -> Undeterminated



In MP4 the language tag can be absent, not necessary to specify [und] like MKV.


The last version is not fixing the problem. It is not possible to selected [Und] in Automation list (see picture)



so if I add an mp4 with no language tag or an MKV with [ Undeterminated ] language tag, the audio is not included.

I think that the best option is to always include a subtitle or audio if the language tag is missing, blank or "Undeterminated"/"Unspecified".

Thanks,
Dan
