o Only do this for realtime applications
o Adjust other track clock based on audio clock
o Assume other track uses wall clock as the media clock
o Use some heuristics to reduce the size of stts box by 2/3.
- also
o Remove one unused key from MetaData.h

- If the target color format is unavailable, the default
platform-dependent color format will be used.
- Also add some logic to prevent looping forever if the
omx component is buggy supporting color format enumeration.

+ This reduces the file I/O block time for audio/video track processing
- Since the file writer is buffering some output samples, the memory
usage would go up, depending on how many output samples are buffered.

Support a single format change at the beginning of audio playback. This way the AAC+ decoder may change its output format from what is originally encoded in the audio stream and we'll still play it back correctly.

The type of the cmd, cmdSize and *pReplySize parameters of the effect control interface command()
function have been modified from int to uint32_t. This is more consistent with their role.

a single call.
Addional changes:
- Fixed simulator build
- Use effect interface UUIDs from OpenSL ES includes when available
- Added cleanspec rules to remove now obsolete test effect libraries
- Fixed bug in AudioEffect JNI setParameter function.

This is 1st part of the work to allow audio and video resync if
we found out that audio and video are out of sync during authoring
- also fixed a problem in AACEncoder::read() where the buffer acquired
from the buffer group does not release when error out at
reading from source.
Change-Id: I8a2740097fcfdf85e6178869afeb9f3687a99118
Added methods to AudioTrack and MediaPlayer java classes to enable use of
auxiliary audio effects. The effect can be attached and detached by specifying its
ID and the send level controlled.
Change-Id: Ie74ff54a453096a742688476f612ce355543b6f3
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.
Change-Id: Ida43484b06e9b890d6b9e53c13958d042720ebdb
- Fixed crash when deleting an effect chained before an effect having volume control
- Changed EFFECT_FLAG_VOLUME_CTRL to implicitely include EFFECT_FLAG_VOLUME_IND
(not need to set both in effect descriptor).
- Volume control changes from one effect to another if needed according to effect enable state
- EFFECT_CMD_SET_VOLUME is only sent when their is an actual change in volume
Change-Id: Ieebaf09157e2627366023569d95516646e03e26c
- Separate the updating of effect engine state from the process call in EffectModule so that the state
of all effects in the same effect chain is updated simultaneusly before all process functions are called.
- Added a mechanism for the effect engine to continue being called for processing after receiving the disable
commands untils it considers that the framework can stop calling the process function without causing
a glitch or loosing some effect tail.
- Updated test reverb and equalizer to support this new feature
Change-Id: Icb56ae2c84c076d4dbad6cf733b1a62f823febe7
Defined the following JAVA classes on top of AudioEffect class to facilitate control
off built-in audio effects with APIs aligned with interfaces defined in OpenSL ES
specification:
- BastBoot.java
- Equalizer.java
- PresetReverb.java
- EnvironmentalReverb.java
- Virtualizer.java
Split reverb API header file in two, one for preset reverb and one for environmental reverb.
Some changes in test reverb to support preset reverb.

The visualizer enables application to retrieve part of the currently playing audio for visualization purpose.
It is not an audio recording interface and only returns partial and low quality audio content as a waveform or
a frequency representation (FFT).
Removed temporary hack made in MediaPlayer for animated wall papers based on audio visualization (snoop() method.
This commit also includes a change in AudioEffect class:
- the enable()/disable() methods have been replaced bya more standard setEnabled() method.
- some fixes in javadoc
Change-Id: Id092a1340e9e38dae68646ade7be054e3a36980e
Also:
- Allowed start() call when encoder already starts and stop() call when encoder has not started yet
- Handled default value for audio/video sources/encoders and file output format
Change-Id: I03b2f7d3cf570baa0fd011a8c0ad200f2f2a5da1
- An alternative would be to define a common base class that
both MediaRecorderClient and MediaPlayerClient can derive.
But since the common code, onTransact() and notify() uses
some Binder code, having a common base class may not gain
us too much in terms of code reuse.
Change-Id: Ibc06720278ad173fceacff3d267b7060856c6316
- Track either the number of A/V frames authored, or the time elapsed
- Track the completion of the authoring
- Add multiple camera support for authoring by accepting a camera id parameter
- Set file type based on the OUTPUT_FORMAT requested
Change-Id: I0f9d31b3b7a8fa43eb53f572410fb0ebd4fa0bb7
Effect API:
- Use different definitions for audio device, channels, formats... in AudioSystem and EffectApi:
Removed media/AudioCommon.h file created for initial version of EffectApi
- Indicate audio session and output ID to effect library when calling EffectCreate(). Session ID can be useful to optimize
the implementation of effect chains in the same audio session. Output ID can be used for effects implemented in audio hardware.
- Renamed EffectQueryNext() function to EffectQueryEffect() and changed operating mode:
now an index is passed for the queried effect instead of implicitly querying the next one.
- Added CPU load and memory usage indication in effects descriptor
- Added flags and commands to indicate changes in audio mode (ring tone, in call...) to effect engine
- Added flag to indicate hardware accelerated effect implementation.
- Renamed EffectFactoryApi.h to EffectsFactoryApi.h for consistency with EffectsFactory.c/h
Effect libraries:
- Reflected changes in Effect API
- Several fixes in reverb implementation
- Added build option TEST_EFFECT_LIBRARIES in makefile to prepare integration of actual effect library.
- Replaced pointer by integer identifier for library handle returned by effects factory
Audio effect framework:
- Added support for audio session -1 in preparation of output stage effects configuration.
- Reflected changes in Effect API
- Removed volume ramp up/down when effect is inserted/removed: this has to be taken care of by effect engines.
- Added some overflow verification on indexes used for deferred parameter updates via shared memory
- Added hardcoded CPU and memory limit check when creating a new effect instance
