cec4abb2a39eafa75cf6894170a200322aa7226e 03-Jul-2012 Eric Laurent <elaurent@google.com> audio policy: fix delayed command insertion

When inserting a delayed command in the audio policy service
command thread queue, later similar commands are filtered out.
In case of volume commands and delayed unmuting, this can cause
a problem where a new volume command can cause the timing of a
delayed unmuting command to not be honored.

This change makes that a volume command gets the time stamp of
any delayed command it replaces.

Various fixes in direct output playback thread implementation:
- threadLoop_write() was broken for playback threads that do not
use a pipe sink.
- output buffer size calculation was hard coded for stereo.
- removed software volume that was implemented for PCM stereo
format only: the audio HAL has to implement volume if needed
for direct outputs.

is not always updated fast enough by audioflinger callback.

9fda4b87441fe17d90d8144639c9de6d9022c3c0 02-Feb-2012 Glenn Kasten <gkasten@google.com> Fixed possible heap corruption in EffectDesc

"EffectDesc *effect = new EffectDesc(*effects[i]);" was relying on the
default copy constructor for EffectDesc, but the default copy constructor
does a member-by-member copy. This works OK for mUuid, but a member
copy of mName and mParams shares pointers. This could result in heap
corruption later on due to a double free. Changed to add an explicit
copy constructor that does a deep copy of both mName and mParams.

A malloc() and strdup() were being freed by delete, but the correct
matching API for these is free(). Fortunately our current memory runtime
implementation ignores the difference. Changed to use free().

EffectDesc and InputSourceDesc member fields were being torn down by
the code that does delete. Changed to do the tear-down in ~EffectDesc()
and ~InputSourceDesc().

Added constructor EffectDesc() with name and UUID parameters, rather
than having caller fill in the object after construction.

Made ~EffectDesc() and ~InputSourceDesc() non-virtual to save memory,
since they have no subclasses.

Was a mix of audio_source_t, uint8_t, and int.

Related fixes:
- fix comments in MediaRecorder.java
- AudioPolicyService server side was not checking source parameter at
all, so if the client wrapper was bypassed, invalid values could be
passed into audio HAL
- JNI android_media_AudioRecord_setup was checking source for positive
values, but not negative values. This test is redundant, since already
checked at Java and now checked by AudioPolicyService also, but might
as well make it correct.

83844cc2f95dc279015b47fd1e18c7cb4eabe9a1 19-Nov-2011 Eric Laurent <elaurent@google.com> audio framework: manage stream volume per device

Improve volume management by keeping track of volume for each type
of device independently.
Volume for each stream (MUSIC, RINGTONE, VOICE_CALL...) is now maintained
per device.

The main changes are:
- AudioService now keeps tracks of stream volumes per device:
volume indexes are kept in a HashMap < device , index>.
active device is queried from policy manager when a volume change request
is received
initalization, mute and unmute happen on all device simultaneously
- Settings: suffixes is added to volume keys to store each device
volume independently.
- AudioSystem/AudioPolicyService/AudioPolicyInterface: added a device argument
to setStreamVolumeIndex() and getStreamVolumeIndex() to address each
device independently.
- AudioPolicyManagerBase: keep track of stream volumes for each device
and apply volume according to current device selection.

db7c079f284f6e91266f6653ae0ec198b1c5006e 10-Aug-2011 Eric Laurent <elaurent@google.com> Audio effects: track CPU and memory use separately

Before this change, CPU and memory usage for an audio effect were
registered and checked against the limit by audio policy manager
upon effect instantiation. Even if an effect was not enabled
it would prevent another effect to be created if the CPU load budget
was exceeded, which was too restrictive.

This change adds a method to register/unregister CPU load only when
an effect is enabled or disabled.
It also adds a mechanism to place all effects on the global output mix
in suspend state (disabled) when an effect is enabled on a specific session.
This will allow applications using session effects to have the priority
over others using global effects.

Also fixes some issues with suspend/restore mechanism:
- avoid taking actions when an effect is disconnected and was not enabled.
- do not remove a session from the suspended sessions list when corresponding
effect chain is destroyed.

57dae99c9fcd6becd2b5ed0c53f277ba4d7dbcfc 24-Jul-2011 Eric Laurent <elaurent@google.com> Added APIs for audio preprocessing

Added APIs to control pre processes applied on captured audio.
Those APIs are still hidden until reviewed by API council.

Three types of standard pre processes are supported:
- Automatic Gain Control (AGC) by AutomaticGainControl class
- Acoustic Echo Cancellation (AEC) by AcousticEchoCanceler class
- Noise Suppression (NS) by NoiseSuppressor class

A method is added to AudioEffect class to query audio pre processings
applied by default by the platform on a given AudioRecord session ID.

7c7f10bd4fda9a084e5e7f0eb3a040dfcbf01745 18-Jun-2011 Eric Laurent <elaurent@google.com> Audio framework: support for audio pre processing

Audio effect framework is extended to suport effects on
output and input audio path.

AudioFlinger: Support for audio effects and effect chains is
moved from PlaybackThread class to ThreadBase class so that
RecordThread can manage effects.
Effects of type pre processing are allowed on record thread
only. When a pre processing is enabled, the effect interface handle is
passed down to the input stream so that the audio HAL can call the
process function. The record thread loop calls the effect chain process
function that will only manage the effect state and commands and skip the
process function.

AudioRecord: The audio session is allocated before calling getInput() into
audio policy serice so that the session is known before the input theead is
created and pre processings can be created on the correct session.

AudioPolicyService: default pre processing for a given input source are
loaded from audio_effects.conf file.
When an input is created, corresponding effects are created and enabled.

eda6c364c253ba97ee45a3adeb8c2b45db1f81db 02-Feb-2011 Eric Laurent <elaurent@google.com> Fix issue 3371080

Modified default volume control logic in AudioService:
1 IN_CALL volume if in video/audio chat
2 NOTIFICATION if notification is playing or was playing less than 5s ago.

Modified silent mode:
- now also affect MUSIC stream type
- entering silent mode when VOL- hard key is pressed once while selected
stream volume is already at 0 (except for VOICE_CALL stream).
- exiting silent mode when pressing VOL+ hard key while in silent mode

Play sound FX (audible selections, keyboard clicks) at a fixed volume.

Modified audio framework:
- isStreamActive() method now implemented in AudioPolicyManagerBase (previously AudioFlinger)
- iStreamActive() now specifies a time window during which the stream is considered
active after it actually stopped.

935752053ef2691dbb6d5a6d149e0e362c6e3c74 19-Jan-2011 Eric Laurent <elaurent@google.com> Tentative fix for issue 3362362.

The problem is likely that one method is called on the AudioPolicyManagerBase
instance while it is still being constructed by AudioPolicyService.

To avoid this, the AudioPolicyService mutex is held by the constructor until the
platform specific AudioPolicyManager is constructed and the member
mpPolicyManager initialized.

Also added an initCheck() method to AudioPolicyInterface to verify successful
initialization of AudioPolicyManager.

A similar change is done in AudioFlinger constructor.
Also added some missing protections in AudioFlinger methods where the
playback thread list is parsed.

de070137f11d346fba77605bd76a44c040a618fc 13-Jul-2010 Eric Laurent <elaurent@google.com> Audio policy manager changes for audio effects

Added methods for audio effects management by audio policy manager.
- control of total CPU load and memory used by effect engines
- selection of output stream for global effects
- added audio session id in parameter list for startOutput() and stopOutput().
this is not used in default audio policy manager implementation.

Modifications of audio effect framework in AudioFlinger to allow moving and reconfiguring
effect engines from one output mixer thread to another when audio tracks in the same session
are moved or when requested by audio policy manager.
Also fixed mutex deadlock problem with effect chains locks.
