bfd2cbaa3f ALSA: allow to dynamically add/remove midi devices & update their latency. 2015-12-04 22:19:47 +01:00
ac075560bd ALSA: allow to measure & set systemic audio latency w/o restart.
(MIDI needs a bit more work)

6b4e5f1d47 ALSA: update error-codes for HW initialization. 2015-10-01 12:42:05 +02:00
dcf327f86a Return meaningful error codes when ALSA backend fails to start
Unfortunately it seems that in zita-alsa-pcmi doesn't set state() correctly in
some cases. Setting an invalid SR doesn't display the correct error message,
first guess would be that set_hwpar is failing and state() is not
representative of the actual error.

548340eb05 remove -Woverload-virtual ambiguity (from 1d3690d)

56cc3e2407 fix portengin get_ports() flags API
require all flags to be present (same as jack)

49ffcd0d9d clamp DSP load displsy 100% & relax LPF. 2015-04-30 02:00:50 +02:00

52e99750a0 ALSA: fix thinko in sample time calc. 2015-03-09 17:17:50 +01:00
09dd3fc369 some backends can handle incorrectly ordered midi events.
(that can happen if multiple sources send to the same
ouput port, in particular async midi events)

782dd70875 alsa: implement timing callback 2015-03-05 01:59:59 +01:00
e3dd226ffa Change order of midi entries so a new backend will default to a working midi system.
Needs testing on all platforms.

582138f280 change Audio backend sample time methods to use a 64 bit timeline 2015-02-19 17:44:01 -05:00
8a93a87db0 remove lib versioning for internal plugins
Those objects do not have a versioned API by themselves.
This fixes issues with duplicate deployment (OSX, Linux bundles: cp) and
ardour listing control-surfaces multiple times (file index plugin dir).

d991bb10ca add 'available' interface to the AudioBackendInfo
If a backend can be loaded, it does not mean that it can be used;
e.g. weak-linked jack-backend if libjack is not available.

b1da9af8de ALSA|Dummy: ignore port unregistration when engine is stopped
When changing Engine parameters, ardour first stops
the engine and only later when re-etablishing ports
unregisters/re-registers them.

ALSA: silently ignore port unregs and silently accept registrations
Dummy: print a PBD::info message,
2014-09-08 01:25:56 +02:00
dc318e6e74 ALSA|Dummy Backend: do as jack does:
when the backend is closed, unregister all ports.
2014-09-07 22:50:57 +02:00
cd12698b9c Rename PBD::find_file_in_search_path to just PBD::find_file
saves a bit of typing and not necessary if you look at how it is used.

fixes possible segfault when the data in the vector
goes out of scope due to RVO.
