# 1fb59be1 14-Apr-2018 Jérôme Duval <jerome.duval@gmail.com>

Fix some usages of BStackOrHeapArray.

Validates the buffer with IsValid() before actually using it. Thanks Rene!


# 17078f99 16-Apr-2016 Dario Casalinuovo <b.vitruvio@gmail.com>

MixerCore: Use a normal acquire_sem call

* Make the thread really wake up only when requested.


# 598880fc 11-Apr-2016 Dario Casalinuovo <b.vitruvio@gmail.com>

MixerCore: Remove wrong flag


# b0dd37b7 11-Apr-2016 Dario Casalinuovo <b.vitruvio@gmail.com>

AudioMixer: Review and rework synchronization

* The event time is managed through the main node control
loop.
* Make the mix thread to activate only when needed.
* Make the locking more simple and remove a race condition,
this will make the thread to be more silent too.


# f4c2f7eb 10-Jan-2014 Jonathan Schleifer <js@webkeks.org>

Remove variable length arrays of non-PODs.

Variable length arrays of non-PODs are not part of the C++ standard, but
a GNU extension that never worked correctly. Instead, BStackOrHeap array
is used now, which makes sure that it's not too big for the stack, calls
all constructors and is valid C++.

mixer.media_addon: fixes 64 bit warnings


# b006bbe1 01-Sep-2010 Stephan Aßmus <superstippi@gmx.de>

* Resolved TODO and implemented updating resampling implementation on the fly.
* Reordered some methods in the source to align with declaration order.
* Applied naming conventions for private methods.
* Switched asterix style in MixerInput.

# a79b30c3 31-Aug-2010 Stephan Aßmus <superstippi@gmx.de>

* In the MixerInput, also use the Linear resampler if requested by the
settings. (There is a common "mixing frame rate" to which all inputs
resample, before the MixerCore resamples to the frame rate of the
output.)
* Some more coding style fixes in MixerCore.

# 77fa0021 12-Aug-2010 Adrien Destugues <pulkomandy@pulkomandy.ath.cx>

Enable the "interpolate" resampling method. Results are not as good as I expected, however.

# b289aaf6 12-Apr-2010 Axel Dörfler <axeld@pinc-software.de>

* A BBuffer does not know where it came from, so
BBufferConsumer::BufferReceived() cannot know whom to send the "buffer is
late" notification (unless we only have a single input). To solve this, the
media_header now contains extra fields that can be used to create a
media_source object.
* Unfortunately, BBufferProducer::SendBuffer() cannot know the output either in
case there is more than one. Hence, I deprecated the existing SendBuffer()
call and moved it into "private" - IOW old sources using it won't compile
anymore under Haiku.
* I introduced a new SendBuffer() variant that also gets the media_source as
argument.
* Updated all sources (that are part of the image) to use the new variant.
* Removed some purposely commented out code in the audio mixer.
* Implemented late buffer notification, as well as late buffer handling in the
audio mixer; this is a bit of work in progress, so the debug output is left
in there.
* Some cleanup.

# f0a85f97 07-Sep-2008 Jérôme Duval <korli@users.berlios.de>

* I misunderstood what means 24 bits B_AUDIO_INT (more than 2 years ago!): as audio data is left justified in a 32 bits container, we don't care much and convert as usual
32 bits data
* Echo audio driver doesn't support 24 bits in a 32 bits container as proposed by the media kit. We just manage 24 bits as 32 bits samples.
* The main benefit of this change is that the hda driver is now working with 24 bits samples (and 192khz).

# bf7ab50d 03-Oct-2007 Stephan Aßmus <superstippi@gmx.de>

large patch by Bek (HOST team):
* style improvements, header reformatting, small refactoring and adding
of missing copyrights

(to Marcus: this is not the original patch, it has already been revised two
times by myself and I thought it was very nice now)

# f916862c 13-Mar-2006 Marcus Overhagen <marcusoverhagen@gmail.com>

Switched to using a local debug header file, instead of using the private media kit file.
This should prevent mixer from beeing build with debug enabled, when media kit is build with debug.
Thus CPU usage will be reduced as mixer no longer prints a lot of information to stdout.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16759 a95241bf-73f2-0310-859d-f6bbb57e9c96


# ff14d245 06-Feb-2006 Jérôme Duval <korli@users.berlios.de>

* mixer media addon builds on beos, fixed includes missing
* added 24 bits B_AUDIO_INT support (20 bits still missing)
Marcus please review and fix if needed

# dfbe8043 08-Sep-2003 beveloper <beveloper@nowhere.fake>

I fixed a timing bug. The mixer was accidentally sending itself
a notification about downstream latency change, when it really
should have send that to the connected inputs. This is now done
by the PublishEventLatencyChange() function.

Cleanup of MixerOutput class, the channel type is now used instead of channel designation or channel_mask
Implemented output channel remapping controls.

# af8d0a4d 30-Jun-2003 beveloper <beveloper@nowhere.fake>

Fixed the input buffer looping bug that existed if an input wouldn't receive new buffers. Now kips inputs that have no available data.
When no input is connected, use a fast path for sending an empty buffer.
No more debugging output when DEUBG < 1

# 60e2e68c 29-Jun-2003 beveloper <beveloper@nowhere.fake>

finally it does mixing, but we should get rid of the CPU eating List template
at this place, as it internally calls malloc, free, new and delete quite often

having an output, followed by starting the node.
fix some bugs of handling an unconnected output
added better locking to the mix thread

* I misunderstood what means 24 bits B_AUDIO_INT (more than 2 years ago!): as audio data is left justified in a 32 bits container, we don't care much and convert as usual
32 bits data
* Echo audio driver doesn't support 24 bits in a 32 bits container as proposed by the media kit. We just manage 24 bits as 32 bits samples.
* The main benefit of this change is that the hda driver is now working with 24 bits samples (and 192khz).

large patch by Bek (HOST team):

(to Marcus: this is not the original patch, it has already been revised two
times by myself and I thought it was very nice now)

Switched to using a local debug header file, instead of using the private media kit file.
This should prevent mixer from beeing build with debug enabled, when media kit is build with debug.
Thus CPU usage will be reduced as mixer no longer prints a lot of information to stdout.

I fixed a timing bug. The mixer was accidentally sending itself
a notification about downstream latency change, when it really
should have send that to the connected inputs. This is now done
by the PublishEventLatencyChange() function.
