* calf-updates:
CALF: resync source files due to forgotten commits
+ JACK host: implemented Save/Save as...; Open not implemented yet - who could possibly want THAT?
+ EQ: Fix adding EQ plugin using menu in calfjackhost
Some changes in style, smaller h/v-scale added
+ LADSPA: make plugin IDs unique across Calf plugins, add an install-time check
+ EQ-5: refactoring to eliminate code duplication, side effect: stereo meters
+ EQ-n: shorter names for calfjackhost and others
+ Equalizers: convert lists of per-band parameters using macros (ugly, but effective)
+ EQ-8, EQ-12: reduce copypasta by using a class template
+ Compatibility: workaround for GStreamer crash bug in Ubuntu 9.10 (thanks to Stefan Kost for diagnosing the problem and suggesting the workaround)
+ Compressor simplification, added optional audio ports
Probably I forgot to cherry pick one or two commits from CALF Git repo
resulting in a slight diverge of source codes. Resynced the concerned
header files. Fixes the missing Pulsator plugin.
In Base64::decode() we mess around with pointers so it's more type-safe
to realize everything as a template function. This also silences compiler
warning about dereferencing type-punned pointer in Vibed plugin.
Removed some old projects that did not represent LMMS and its abilities
anymore. We also need to replace most of the "Cool songs" and replace
them by more recent projects from LSP.
Users reported the last buffer played repeatedly while the dialog asking
whether to save project is shown. This behaviour even continued while
loading a project. An easy workaround for this is to stop playing song
(or whichever TrackContainer is active at the moment) in
MainWindow::mayChangeProject().
Closes bug #2904781.
As of Stk 4.4 all classes and types have been moved to the namespace "stk".
This breaks build of the Mallets plugin. This can be easily fixed by
using the namespace "stk". For compatibility reasons we have to declare
the namespace before, because it did not exist in previous versions.
Closes#2870878.
It's not a good idea to allocate the buffer for VST chunk data on the
stack as chunks might become quite big (several megabytes) and thus
could cause a stack overflow. Fix this by using new/delete.
We have to lock Mixer when touching Song's state via Song::startExport()
and Song::stopExport() in ProjectRenderer::run() as the FIFO writer
thread may call Mixer::renderNextBuffer() (which calls Song::doActions())
simultaneously. Fixes a random segfault when exporting project.
This was a new bug as the ProjectRenderer does not operate FIFO-less
anymore.
* auto-save:
don't change the current project when auto-saving
auto-saves every minute and recovers upon crash
don't show WelcomeScreen when importing/loading
Conflicts:
src/gui/MainWindow.cpp
* fx-mixer-rework: (25 commits)
FxMixer: use new CPU::bufMixCoeff()
Cpu: added BufMixCoeff + SSE implementation

There's no need to start the ProjectRenderer thread with high priority
anymore as the actual rendering is done on the other side of the FIFO.
The ProjectRenderer just waits for new data in the FIFO and encodes
them as they arrive.
Renamed the ProjectRenderer::OutputSettings structure to
ProjectRenderer::EncoderSettings to better reflect its meaning.
Additionally added some basic Doxygen comments.
Until now, Mixer not only was responsible for rendering audio buffers
but also managed writing them to audio backend (through a FIFO) and
handled various quality related parameters.
All this functionality has been moved into the new AudioOutputContext
class. It glues together AudioBackend (formerly called AudioDevice),
global quality settings and the Mixer.
The AudioOutputContext class creates a FifoWriter which calls
Mixer::renderNextBuffer() and writes the output into the BufferFifo of
the AudioOutputContext it belongs to. The BufferFifo is read by the
according AudioBackend which belongs to the AudioOutputContext as well.
The AudioOutputContext also handles resampling in case the AudioBackend
wants the buffers in a different samplerate.
During this rewrite the Mixer class and the according source files have
been renamed from "mixer" to "Mixer". This results in small changes
all over LMMS' code base.
This reverts commit c517f1fa5a.
The commit was not very helpful and introduced new xrun problems.
Instead I'll be rewriting the part of LMMS where Mixer, Mixer's
quality settings, Buffer FIFO and AudioDevice are sticked together.
There's really no need to allocate a buffer each period, push it to the
FifoBuffer and free it when fetching the buffer in
AudioDevice::getNextBuffer(). Instead keep the pointer in FifoBuffer's
pool and reuse it.
Try to adjust latency of PulseAudio according to our settings of mixer
so it does not have such a bad latency anymore.
Furthermore force PulseAudio to play silence instead of rewinding
streams in case of underruns.
There have been some problems with the threading logic in the
AudioPulseAudio backend resulting in an endless loop when quitting LMMS.
Furthermore allocated PulseAudio resources were not freed properly.
Thanks to Armin Kazmi <armin.kazmi@tu-dortmund.de> for pointing out
this issue.
every time auto-save ran, it would change the current project to
"recover.mmp". Now it doesn't do this because Song has
guiSaveProject(), guiSaveProjectAs(), and saveProjectFile().
(the latter is used for auto-save)
