2016-11-02fix LTC-generator 24h wraparoundRobin Gareus
2016-07-14enough with umpteen "i18n.h" files. Consolidate on pbd/i18n.hPaul Davis
2015-01-09fix LTC alignment.Robin Gareus
LTC-slave: offset the parsed LTC-frame instead of changing the frame's timestamp. This fixes an issue with freewheel timeout and delta-calculation. Align transport-time with output to match capture alignment: "with existing material". LTC-generator: follow suit. align clock with master-bus out. This is a semi-permanent workaround. Once [tracks feeding] the master-bus is/are delayed to align to output. The generator needs to use (worst_track_latency not worst_playback_latency)

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
