78a66b7180 improved port cleanup as backend is destroyed 2020-04-07 23:26:51 -06:00
32734ce53c fix portaudio backend to use shared_ptr 2020-04-07 16:00:22 -06:00
b9cb306e8b use shared_ptr to manage backend port lifetimes (Pulse,ALSA,Dummy,JACK)
JACK is not yet finished.

Changes also include minor reformatting and a spelling correction (latecies to latencies)

NO-OP: fix some Wimplicit-fallthrough
gcc can recognize various regexps in comments. Since C++17 provides
[[fallthrough]], using /* fallthrough */ consistently seems
appropriate until we switch to C++17.

Remove ambiguous API implementation
* PortEngine::available() implementation
* AudioEngine::connected() wrapper

Eventually we may re-introduce PortEngine::available along
with a libardour internal port-engine.

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.

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

class RingBuffer<> is a very generic name and should not pollute the
global namespace.

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.

df659e91f1 Consolidate _realtime_pthread_create() into libpbd. 2017-08-29 17:25:23 +02:00
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.

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.

ba78359129 prepare for update to waf 1.8
uselib is no longer implicit (inherited by .use). This is still incomplete,
some uselibs for non-linux variants may be missing.

bld.is_defined("HAVE_XXX") also no longer works and will have to be
changed (I think to bld.env["HAVE_XXX"]) in countless places.

e9be313c11 Fix latency compensation for audio data in portaudio backend
For drivers that correctly report latency values(ASIO) this should result a
much closer alignment of audio in a loopback test. Measurement and
adjustment may still be needed, especially for non-ASIO drivers.

Testing with the RME HDSP Multiface and Yamaha AG06 using ASIO drivers results
in maximum offset of a couple of samples.
