Added new build option WITH_JACK_DYNLOAD for CMake and
WITH_BF_JACK_DYNLOAD for SCons, which means there'll be
no build-time linking against libjack and getting symbols
from libjack will happen runtime using dlopen and dlsym
tricks.
Alternative would be to use weak linking, but it'll require
having wrapper for preloading libjack.
This new options are disabled by default and they only
intended to be used on linux. Other platforms shall not
be using this and there shall be no functional changes
on non-linux platforms at all.
Patch makes it possible to compile blender with recent ffmpeg
and libav libraries, mainly by getting rid of deprecated API.
Original patch by Campbell Barton with own modifications to
support compilation with older ffmpeg versions.
This patch could break compatibility of FFV1 videos playing
back in older players, mainly because of alpha support changes.
Preserving compatibility with such players became a headache
and think it's high time to get rid of workarounds here.
This switches some areas of Blender which are related on FFmpeg stuff
from deprecated symbols to currently supported one.
Pretty straightforward changes based on documentation of FFmpeg's
API which symbols should be now used.
This should make Blender compatible with recent FFmpeg 0.11.
Should be no functional changes.
- Remove strict flags from files, which are using FFmpeg stuff
We're still using some symbols which are marked as deprecated.
Ideally, we shall switch to new API, but it's a bit larger challenge
because we don't want to break compatibility withotu actual need.
- Replace MAKE_ID with BT_MAKE_ID in bullet library.
This is needed to prevent re-definition of MAKE_ID in bullet library.
Seems it's only used to read blender files, so should be quite safe
change.
fix for [#31097] glibc error when playing sound using BGE
by Wander Lairson Costa
Note: This deadlock fix makes the code non-threadsafe again, a proper solution has to be found still.
* Fix for [#31099] Audio in Meta-Strips Plays Beyond Strip Cut
* Adding a split files option to the mixdown operator which then renders each channel into a separate file
made some small edits
- removed changes to AVI reading since the data types are apart of the format spec.
- absf -> abs for a double value in render code.
- use Py_ssize_t when dealing with python sequence sizes
- dont call PySequence_Size(py_b) in a loop (its slow).
- use faster sequence/float parsing in aud.Factory.filter
- define __BIG_ENDIAN__ or __LITTLE_ENDIAN__ with cmake & scons.
- ENDIAN_ORDER is now a define rather than a global short.
- replace checks like this with single ifdef: #if defined(__sgi) || defined (__sparc) || defined (__sparc__) || defined (__PPC__) || defined (__ppc__) || defined (__hppa__) || defined (__BIG_ENDIAN__)
- remove BKE_endian.h which isn't used
* Fix for high quality upsampling which was wrong.
* Fix for doppler effects which were calculated wrong for scenes.
* Improved animation evaluation at the beginning and end of a scene.
Now all sounds that are not mono but have 3D checked automatically get reduced to mono during BGE conversion time.
Also removed the now unneeded function sound_get_channels and added a missing header file to audaspace's CMakeLists.txt.
Important note: I used rsync to do the local merge, as "svn merge --reintegrate ^/branches/soc-2011-pepper" doesn't work with our svn server right now!
Final GSoC commit.
* Bugfix: Negative frames crashed
* Bugfix: JOS sample buffer size prediction error (wasted memory)
* Optimisation: for JOS upsampling (around 12 % difference measured here)
* Optimisation: Better filter for JOS resampling
* Bugfix: Error in relative 3D audio code.
* Removed Attenuation
* Bugfix: Multiple scenes in BGE lead to errors, BGE audio now all relative, to support multiple scenes.
High quality resampling on mixdown, linear for playback.
* Lots of improvements and fixes for the JOS resampler, now it works fine!
* High quality filter coefficients for the JOS resampler (sorry for the 5 MB source file).
* Fix for GE orientation bug. Note: moto uses x,y,z,w quaternion storage, while rest of blender uses w,x,y,z.
* Minor changes/fixes.
Adding a mono flag to mixdown non-mono sounds for 3D audio.
* Added mono sound loading.
* Bugfix: AUD_COMPARE_SPECS usage was wrong.
* Bugfix: JOS resampler = instead of ==.
* Bugfix: Change of a sound should apply settings in AUD_SequencerHandle.
* Bugfix: Memory leak when canceling open sound operator.
Improved waveform drawing in the sequencer.
* Drawing the waveform of a sequencer strip is now independent from whether the sound is cached or not.
* Improved drawing of the waveform in the sequencer (especially speed!).
* Making it possible to vertically zoom more in the sequencer to better see the waveform for lipsync.
* Fixed a bug which crashed blender on loading a sound file via ffmpeg.
Speaker objects fully functional!
Minor changes:
* Fixed three memory bugs found via valgrind.
* Fixed bug with jack transport crashing after file loading.
* Sound NLA Strips now start at CFRA instead of 0.
* Pepper depends on ffmpeg 0.7.1 or higher now, windows and mac build systems set to ffmpeg-0.8
* Fixed orientation retrieval in OpenAL device code.
* Added stopAll() method to AUD_IDevice (also for Python) and call it on BGE exit
* Changed BGE to use audaspace via native C++ instead over the C API.
* Made AUD_SequencerFactory and AUD_SequencerEntry thread safe.
* Changed sound caching into a flag which fixes problems on file loading, especially with undo.
* Removed unused parameter from sound_mute_scene_sound
* Fixed bug: changing FPS didn't update the sequencer sound positions.
* Fixed bug: Properties of sequencer strips weren't set correctly.
* Minor warning fixes.
Mixdown functionality.
* Mixdown possible via libsndfile and ffmpeg!
* Fixed some ffmpeg deprecation warnings
* Mixdown UI only shows working Container, Codec and Format combinations!
* Minor bugs and warnings fixed
Implementation of Julius O. Smith's resampling algorithm for high quality audio resampling.
The filter currently is a sinc filter with a 0.9 cutt-off and windowed by a kaiser window (beta = 10).
Also includes minor changes in the linear resampler.
* Minor audaspace library improvements.
* Considering location, velocity and orientation in AUD_SequencerReader and AUD_SequencerHandle.
* Bugfix: Maximum and Minimum volume weren't used before in the software device.
* Bugfix: Adding speaker objects via info space crashed.
* Listener settings now get updated in the audio system.
Implemented basic audio animation.
* AnimatableProperty: Propper cache writing and spline interpolation for reading (the solution for stair steps in audio animation)
* Animatable properties so far are: volume, pitch, panning
* Users note: Changing the pitch of a sound results in wrong seeking, due to the resulting playback length difference.
* Users note: Panning only works for mono sources, values are in the range [-2..2], this basically controls the angle of the sound, 0 is front, -1 left, 1 right and 2 and -2 are back. Typical stereo panning only supports [-1..1].
* Disabled animation of audio related ffmpeg output parameters.
* Scene Audio Panel: 3D Listener settings also for Renderer, new Volume property (animatable!), Update/Bake buttons for animation problems, moved sampling rate and channel count here
Main: Complete rewrite of the sequencer related audio code to support 3D Audio objects later and especially adressing the animation system problems (see mailing list if interested).
Note: Animation is not working yet, so with this commit volume animation doesn't work anymore, that's the next step.
Minor things:
* Changed AUD_Reference behaviour a little to be more usage safe.
* Fixed bug in AUD_I3DHandle: Missing virtual destructor
* Fixed enmus in AUD_Space.h
* Fixed a warning in rna_scene.c
* Removed an unneeded call in rna_sound.c
* Reviewed and improved the linear resampler. Now it should work pretty good also for special cases that caused errors previously.
* Fixed a crash in the GE when a sound actuator doesn't have a sound assigned.
* Corrected the OpenAL device's threading code. This is a bugfix for #27913, thanks to Juha Mäki-Kanto for helping to resolve this.
* Fixed a warning in AUD_DoubleReader.cpp
* Removed some unneeded includes
* Fixed a bug resulting in a crash when stopping a sound
* Fixed a bug where a NaN resulted in a horrible memory error
* Fixed a typo bug which caused crackling in audio playback and export
* Added memory debugging code (ifdefed)
