2018-09-18new transport slave/master implementation, libs/ editionPaul Davis
2017-09-18globally change all use of "frame" to refer to audio into "sample".Paul Davis
Generated by tools/f2s. Some hand-editing will be required in a few places to fix up comments related to timecode and video in order to keep the legible
2017-01-10Fix MTC slave implicit return on transport-stopRobin Gareus
MTC returns not-locked (no flywheel) when the signal is lost, in which case Session::follow_slave() jumps to no_roll and ignores the slave-position. The MTC slave does explicitly request a transport-locate and transport-stop. Yet, Session::realtime_stop() honors _requested_return_frame for whatever reason
2016-12-08Clarify "frames" (video, timecode) vs "samples" (audio)Robin Gareus
2016-07-14enough with umpteen "i18n.h" files. Consolidate on pbd/i18n.hPaul Davis
2015-10-04globally remove all trailing whitespace from ardour code base.Paul Davis
Paul Davis was responsible for introducing almost all of this.
2015-06-29Add some libardour support for indicating MTC active status.Paul Davis
The general design here is wrong, because it should be more general and cover all possible sync sources. But it does work, it is used in Tracks, and my attempt to do it correctly revealed the problem to be an EXTREMELY difficult design issue (as in: two weeks of work on it did not really solve the fundamental issues with slave design). So, here it is for now, c/o Grygorii

2013-08-13fixes to get MTC (and probably MIDI clock) slaving working againPaul Davis
incoming MIDI data has to be parsed EVERY process cycle, not just when Slave::speed_and_position() is called. The private MIDI::Parser owned by the MTC and MClck slaves was irrelevant, since the port has its own. See comments in midi_port.h on the strangled inheritance heirarchy.

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
