Hi all,
I'm facing the need of converting SMPTE LTC time-code* (encoded in an
audio stream) into MTC timecode, to then route to other applications.
Does anybody know a Linux application for that, or a library to decode
that audio? Any advice will be appreciated.
Thanks,
P

ltcsmpte.sf.net en/decodes SMPTE.
It includes a simple JACK tool that displays incoming LTC and can encode
jack-transport to LTC.
An MTC encoder is not too hard, although synchronizing to quarter-frames
and compensating jack-latency requires some diligence.

Hi Pau, hi Brian (who asked for the same some days ago)
I implemented this many years ago.
http://www.iua.upf.es/~mdeboer/from_ftp/projects/SMPTE/
Robin Gareus used/rewrote the code for a project of his,
so I put him in Cc.

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
http://www.barney-wol.net/time/timecode.html
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
cheers,
robin
