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
2017-09-18attempt fix for LTC slave when locatingPaul Davis
2017-07-26Fix initial sync to LTC with small buffersizesRobin Gareus
Ardour follow_slave() does nothing (not even seek) if the slave is not locked. The LTC-slave assumes it's locked if LTC is stable for 5 continuous process-calls. If the difference of Ardour's transport-position to the LTC-timecode is large (> 2sec), the slave reset itself (assuming drift, seek don't vari- speed). A LTC-slave does reset does reset the locked counter. Hence: If initially Ardour's transport differs > 2 sec and the buffersize is small (many process-callbacks), the slave kept resetting itself never informing Ardour that it locked to the external TC, and Ardour never issued a seek.

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

2012-11-05tigten LTC Slave resolution.Robin Gareus
The reason for this is that the LTC generator uses the slave's resolution as watermark for max-drift, resync. A possible drawback: session-process will force silent rolls if the delta is larger than the resolution. LTC has a carrier freq of ~2kHz, choosing half of that seems a good compromise. git-svn-id: svn://localhost/ardour2/branches/3.0@13380 d708f5d6-7413-0410-9779-e7cbd77b26cf
