I'm using the org.videolan.android:libvlc-all:3.3.6 library.

The above subtitle file consists of two languages.

I want to output subtitles by selecting one of the two languages from the subtitle file.

Please tell me how to do it

Are you saying you want to select 2 subtitle tracks at the same time?
