7e2c002ef6 Propagate Latency to backend/system ports (Dummy backend)
amend ab3889ff (which implements this for other backends)

e39a8b90d9 amend ab3889ff: portaudio backend uses a vector for connections 2017-09-23 01:06:10 +02:00
ab3889fff8 Propagate Latency to backend/system ports
Set accumulated capture-latency for physical-outputs
and accumulated playback-latency for physical-inputs
after Ardour is done setting all non-physical port latencies.

This will be needed for latency-compensation of the complete graph.

666aa5a557 More Coreaudio SDK fixes, after 30b087ab3 2017-09-19 05:20:05 +02:00
1ec471c961 partially revert 30b087ab3, CoreAudio SDK uses "Frames" 2017-09-19 04:47:10 +02:00
30b087ab3d globally change all use of "frame" to refer to audio into "sample".
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

467c801ce8 Abstract definition of rt-scheduler policy
pthread-w32 does not support pthread_setschedparam() with
SCHED_FIFO and bails out. While pthread_create() simply ignores the policy
and sets the priority regadless.

This only affects ctrl-surface event-loops & AutomationWatch on Windows.

587a2dee55 backends: jack: display playback only devices
When starting ardour using the jack backend, playback only devices
currently do not get displayed. Mixing and Mastering only workspaces
with e.g. a single USB Dac should be a common use case. Take this use
case into account by adding them to the device list. Tested on Linux
with jack-alsa.

26dc287c00 Fix non-buffered PA backend. Wait for backend to become active
This hopefully fixes an issue with port-registration (new session)
being skipped because PortAudioBackend::available() still false
until the first callback.

bf5864aaca Use PBD::to_string() from pbd/string_convert.h in JACK utils
Use pbd/string_convert.h API instead of std::ostream for numeric formatting to
remain locale independent and not have to use a LocaleGuard.

6968c9f909 Drain ALSA raw-midi buffers after 64 bytes
Very long sequence of *concurrent* events may otherwise be truncated
because the backend requests a buffer-size of 64 bytes via
snd_rawmidi_params_set_buffer_size().

d10913e2de Fix intermittent hang when stopping PortaudioBackend
This issue is not always reproducible but when it does occur it happens
somewhat consistently on both 32bit and 64bit builds(Tested on Windows 7).

The midiOutReset call does not return (or it takes so long that it might as
well be indefinite) and as it is not strictly necessary just remove it.

33e95a1577 rename Tempo _beats_per_minute to _note_types_per_minute, provide pulse helpers.
- adds quarter_notes_per_minute(), note_divisions_per_minute (double)
	  pulses_per_minute() and frames_per_quarter_note()

	- this should be a no-op except for the use of tempo by
	  the vst callback which definitely uses quarter notes per minute.

	- the XML node for TempoSection named 'beats-per-minute'
	  has been renamed.
