I'm not sure if ffmpeg will be able to decode the SMPTE audible timecode
track. I'll defer to others with more experience with regards to ffmpeg's
capabilities, but you might want to look into libltc and specifically
>From libltc webpage:
"Is there [free] software is using libltc?
yes, ltc-tools <https://github.com/x42/ltc-tools>. It comprises
to generate and decode LTC from live sources and includes tools to read or
write LTC from/to audio-files. xjadeo <http://xjadeo.sf.net/> video-monitor
has been updated to use libltc, and ardour <http://ardour.org/>3 DAW fully
supports chasing and latency free [re]encoding of LTC since svn rev 13390."

Hope this might be useful.
