[FFmpeg-user] how to add more than 1 stream of audio to a TS file setting the language?

[Wagner Patriota]

I have:
video.ts [only video]
english.ts [only audio AAC]
french.ts [only audio AAC]

I want to have an MPEG-TS file where I can switch the language from english
to french... very simple... how do I do it?
