[FFmpeg-user] Get RFC6381 codecs representation using ffmpeg/ffprobe

Hello all,

So I have whatever video and I need to obtain the RFC6381 representation 
of its codecs: https://tools.ietf.org/html/rfc6381

For example:
"avc1.640028" means: H.264/AVC video, High Profile, Level 40
"mp4a.40.2" means: AAC-LC

I assume ffmpeg knows very well about those things but I've run both 
ffmpeg/ffprobe on the video but can't find any trace of those things in 
the output. Or am I missing something?
