i wish to output the info output of a video to a language other than ENG

How do i do this?

I found this here

which tells me

Set the language of the library

The library is by default set in English.
You can change the language with a language string.
MediaInfo::Options("Language", "**LANGUAGE_STRING**")
**LANGUAGE_STRING** is CSV-like string :
Internal name1;translation1
Internal name2;translation2

but i do not understand the syntax; how to do this

i do not want the language permanently changed just for the one-time output

Any of you done this before or understand the syntax? thanx shan
