2013-01-09remove timecode subframe configurationRobin Gareus
There is no actual use-case to set it to anything else than 100. timecode subframes are only used for ruler marks and the snap to grid. libtimecode is still /aware/ of the subframe setting. git-svn-id: svn://localhost/ardour2/branches/3.0@13817 d708f5d6-7413-0410-9779-e7cbd77b26cf
2012-11-13implement TC offset for slave&generator.Robin Gareus
Many related changes that require atomic update, mostly because ClockOption slots changed: * change offset config format to std:string (backwards compat - reads 0) * make Timecode offset independent from fps * sample_to_timecode() handle negative sample-num * audio-clock fix entry and edit of negative numbers * option editor: - remove old global internal offset - add slave & generator TC entry - still needs UI cleanup, tooltops, maybe sep. tab.. * LTC & MTC slave& generator: - cache offset - subscribe to parameter changes git-svn-id: svn://localhost/ardour2/branches/3.0@13485 d708f5d6-7413-0410-9779-e7cbd77b26cf

2012-10-10fix and improve MTC-slaveRobin Gareus
- MTC-speed average (MIDI thread) * base timing on quarter-frames * replace hann-window average with a DLL - MTC/engine alignment * replace 1st order PI-controller with 2nd order DLL The 2nd DLL is needed because the jack-process callback effectively quantizes the transport-speed to integer audio-frames (speed * nframes). This leaves a delta on every cycle because the remainder from previous cycles is not compensated for. Theoretically it is possible to merge the two DLLs into one. However, with callbacks coming from by two independent threads it is cleaner to track the MTC and JACK engine-alignment speeds independently. git-svn-id: svn://localhost/ardour2/branches/3.0@13226 d708f5d6-7413-0410-9779-e7cbd77b26cf

2012-05-24Remove over 500 unnecessary includes (including 54 of session.h).David Robillard
It's slightly possible that this causes trivial build failures on different configurations, but otherwise shouldn't cause any problems (i.e. no actual changes other than include/naming/namespace stuff). I deliberately avoided removing libardour-config.h since this can mysteriously break things, though a few of those do seem to be unnecessary. This commit only targets includes of ardour/*.h. There is also a very large number of unnecessary includes of stuff in gtk2_ardour; tackling that should also give a big improvement in build time when things are modified. git-svn-id: svn://localhost/ardour2/branches/3.0@12420 d708f5d6-7413-0410-9779-e7cbd77b26cf
