[FFmpeg-user] Dual Language in Satellite TV

[Bhikkhu Mettavihari]

Greetings from Sri Lanka

I run several Educational Channels via  a local Satellite in *one* of our
local Languages.
I have been given the challenge to generate the same program in 2 languages.

It would be the same presenter who would give the lesson in language 1 as
well as language 2.
This should be done in a way that the Television receiver can switch from
language 1 to language 2 at his choice.

I would very much appreciate to have a hint where to look for help on this
subject.

Our present production is done fully in Linux and the final product is
compressed using ffmpeg.
This may or may not be an ffmpeg question, but I was hinted at,  is that
ffmpeg can include the 2nd track into the video file.

Thank you for you patience if this is the wrong place.
