https://ltcsmpte.svn.sourceforge.net/svnroot/ltcsmpte/ltc2amidi/trunk/

a try. It includes two tools:

jack2amidi and jack2jmidi which send jack-transport as MTC to an

ALSA-MIDI or JACK-MIDI port respectively.
libltcsmpte is in debian and the tools may readily be available on

Ubuntu, I don't know.
caveat: run jackd at a small frames/period rate e.g 64 fpp or 128, the

period size should smaller than audio-frame/video-frame.
IIRC Egor's jackmtc has or had the same issue that it can skip SMPTE

frames if the SMPTE-frame-duration / jack-frames-per-period > 1.0.
Cheers!

robin
