These processors don't have a UI, so their load stats are not easily
visible. The stats can still be queried via Lua API or DSP-load
overview window, so we retain this for debug builds.

Use AU's preset->presetNumber as identifier since std::map are sorted
this also indirectly sorts presets by preset-number. (user presets
start with a '/' and are listed first, sorted by name).
Since Presets are now identified by URI on session load (53a0199a0)
and AU user-presets can added/be removed (since ae4604a24b7), simple
sequential numbering is no longer an option.
|
|
This works around async parameter-changed signal emission when loading
an AU preset. A simple timeout is used to delay making the preset
as modified.
|
|
|
|
This checks if the preset is actually available on the given system
and also sets the user-flag correctly.
|
|
This is a step in the right direction: first load the preset and
only if preset-loading was successful mark it as loaded.
This still does not properly unset "parameter_changed_since_last_preset".
AU signals "kAudioUnitEvent_ParameterValueChange" later in the event-loop.

load_property_list() takes a file-path (not URI). Actually it's not
clear why we've ever used a `file:///` URI internally.

This fixes a memory-leak (_midi_buf was allocated in DiskIOProc
but only delete in DiskReader). Also skip midi-refill early on
|
|
Disk-writer run() can concurrently use the ringbuffer after it was
free()ed by the butler thread.

* PortEngine::available() implementation
* AudioEngine::connected() wrapper
Eventually we may re-introduce PortEngine::available along
with a libardour internal port-engine.
|
|
available(), connected(), running() were ill-defined and
used interchangeably.
|
|
Session::new_route_from_template() unconditionally calls
IO::disable_connecting(), and needs to be reverted likewise
(no RAII here).

Adding/removing the Monitor section changes port-connections,
a port-engine is needed to establish connections.
Ideally we'd allow this and queue for connection changes. This
will however require deep changes.
Also toggling the monitor-section on/off/on w/o engine can later
result in failure to register ports. Due to lack of engine-signals
not all shared_ptr<> port references are dropped.
|
|
Previously Port::PortDrop was never handled.
The signal was disconnected directly when the connection
is re-used by Port::PortSignalDrop.
Ports::drop() was not called when the engine was stopped
or disconnected, and port-handles were not invalidated.
This lead to crashes whenever a port-related operation was performed
while the engine was stopped. e.g. adding/removing tracks or plugins
(latency recompute, notify port-engine) and various other operations.

At this point in time MIDI buffers are vastly over-sized.
They include VST and LV2 event structure. This added about a MB per
plugin for no benefit.
|
|
This fixes an error while loading shared libraries: libardour.so
R_PPC64_ADDR32 reloc at 0x... for symbol `' out of range
Treating a local as an immediate value in asm code makes the library
non-relocatable.

remove_processor() also calls drop_references, when successful.
|
|
Whitespace between XML nodes can result in "text" children.
Those need to be skipped in the patch-name list.

This saves some memory (gmsynth loads a 30MB soundfont), and also
re-initializes the synth every time to gm defaults in case some
.mid changes patches or parameters.

SFC_SET_COMPRESSION_LEVEL was only added in 2012 and only available in
libsndfile 1.0.26 or later.

This keeps track of lv2:Parameter properties modified with Port:Set,
currently file-paths.
|
|
This allows to restore ProfileManager's ExportFormatSpec without
re-instantiating the ProfileManager.
|
|
|
|
|
|
|
|
This also prepares for codec-quality defaults, but
ExportFormatSpecification does not yet set those for previously unset
or new formats/presets.

* missing include for locale_to_utf8 (amend 4c6ff5f7e7)
* avoid void* arithemtic (amend 103ef2ba)

This adds an experimental pipe to ffmpeg to encode mp3. Currently
quality is hardcoded and various aspects remain to be implemented.
However, it is sufficient for initial testing.
|
|
A first step towards allowing external encoders without intermediate
temporary file.
|
|
This is in preparation to allow calling ffmpeg, or similar (sox, lame,..)
directly from libardour.
