http://ltcsmpte.sf.net started from Maarten's SMPTEDecoder-0.1.3 codebase.
It was modified to become re-entrant, a build system for a shared lib,
and encoder&decoder tests were added. Additionally libltcsmpte includes
support for big endian systems and SMPTE date support as per
My use-case a few years ago was film-postproduction, but since Pau
asked, I dug out some experimental/unfinished code that uses libltcsmpte
to generates MTC seeks (sysex messages - _not_ MTC quarterframes) from a
jack-audio port: http://rg42.org/_media/wiki/ltc2amidi-0.1.0.tar.gz
