a67a475480 dramtically improve performance of ::get_port_by_name() for JACK backend 2021-06-11 10:41:41 -06:00
5957e14259
Remove unused #include<> (2/2)
PBD::stacktrace() is not used nor needed by default.
It should be used sparingly.

JACK backend allows to calibrate latency
However, if jackd is running, we should test if jackd is using
a full-duplex device to establish if latency calibration is
possible -- fix 92f54b3e98.

Con't work on ALSA nperiod selection (see also d3d120fa) 2020-04-28 17:56:17 +02:00
70f13a3ff3 use RCU to manage JACK backend's container of ports 2020-04-08 19:56:33 -06:00
d827f3fdae fix up shared_ptr<> use in JACK backend 2020-04-07 13:23:49 -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)

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

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

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

2a89234027 move control app launching back into audio backend to allow ASIO/CoreAudio model to work; push initial state of AMS dialog to backend
Issues remain with the basic model of the AMS dialog - when is
newly chosen state pushed into the backend (which can then
modify the control app button sensitivity. This is a special
problem for this button because APIs like ASIO and CoreAudio
probably don't allow us to launch a control app for an arbitrary
device, but only one actually in use. In this sense it is
different from properties like available buffer size etc, where
we can typically query without actually using the device.

ecfeeda4b8 launching control app is now responsibility of ardour GUI, not audio backend; use ARDOUR_DEVICE_CONTROL_APP if set in the environment 2013-09-09 16:48:27 -04:00

a228643e40 add can_change_{sample_rate,buffer_size}_while_running() methods to an AudioBackend
Allows the GUI and other stuff to know whether or not changing the SR/bufsize is possible while running, which is about to become useful
2013-09-09 15:17:43 -04:00
f4cf283f26 move JACK audio backend to its own folder and adjust build system to reflect that (installed version may now work) 2013-09-07 11:03:57 -04:00
