Get information about subtitles maps

[anonym24]

How can I get information about subtitles (text) tracks - maps?

or how can I get next output to parse manually?

fmpeg -i input.mkv
ffmpeg version ... Copyright (c) 2000-2012 the FFmpeg developers
Input #0, matroska,webm, from 'input.mkv':

    Stream #0:0(eng): Video: h264 (High), yuv420p, 1920x800, 23.98 fps, 23.98 tbr, 1k tbn, 47.95 tbc (default)

    Stream #0:3(ger): Subtitle: text (default)
At least one output file must be specified

from this output I can find out which map do I need and language code of audio or subtitles

it's possible with FFmpeg binary (static) but what about this library which uses shared libraries files?

or how even execute next simple function ffmpeg --version and get output?
