Use AudioPlayback_Parameters more consistently in parameter list of
constructors. Also, StreamPlayer::StreamPlayer was over-assigning to
mPlaybackParams (already assigned by its superclass's constructor).

Move initialization of AudioPlayback_Parameters from each case
to before the switch, as it is shared by each use case.

Remove old asserts.

b4393ef4ef3edb785746c37fd7b68950e85283ae 30-Sep-2011 Glenn Kasten <gkasten@google.com> Multithread safety and code reduction

Remove unsafe GenericPlayer::getSampleRate(). getSampleRate() was not
thread-safe as it accessed a member variable updated in the looper thread
without a lock. If getSampleRate() is ever needed again, the sample rate
is available in the mPcmFormatValues array, which does have a lock.

Replace member variables mChannelMask, mChannelCount, and mSampleRateHz
by local variables for locality and performance.

Add callback protector for decode to PCM usage cases.
Move callback protection up earlier for URI decode use case only.

Remove redundant mCallbackProtector field.
Optimization: on exit from callback protector, only broadcast if !mSafeToEnterCb,
that is if destroy has requested callback protectors to finish up.
More callback protector logging.
Add callback protector requestCbExit() [no wait], not yet used.

3rd parameter of adecoder_writeToBufferQueue is always CAudioPlayer * instead of void *.

This version should be more resilient to decode time vs. real time.

- comment about GetPosition accuracy
- remove unused AudioSfDecoder::onRender implementation

54cad4f35a090a06e655fcc9e072e1d38f9e7689 20-Jul-2011 Jean-Michel Trivi <jmtrivi@google.com> Fix bug 5049371 Metadata for decode to PCM buffer queue

When decoding a URI or FD with OpenSL ES to a PCM buffer queue,
you cannot rely on the information given by the extractor, or
the OMXCodec before the latter has decoded one buffer.

The fix consists in two parts:
1/ where to retrieve the PCM format from:
the information first retrieved from the extractor if available,
but then overwritten by the OMXCodec values as soon as it
2/ when can the application retrieve the information:
the information is available when the first buffer of decoded
data is returned to the application via the buffer queue
callback. The test app is updated to reflect this, and verify
that the query can safely happen during the callback.

Added a preDestroy() mechanism for the subclasses of
Added a lock around the update and use of the callback
GenericPlayer is using for notifications to the
OpenSL ES framework. This prevents notifications after
the GenericPlayer is flagged for destruction.
Added a lock to protect the update of the audio source
running state, so it doesn't get used after the
AudioSfDecoder is flagged for destruction.
Before stopping the audio source of an AudioSfDecoder
object, release the code buffer if necessary, to
ensure proper teardown of the audio source (OMXCodec)

7f5cc1afe49395fefaad9b2bbd728a45d1bfda6a 16-Jun-2011 Jean-Michel Trivi <jmtrivi@google.com> OpenSL ES: additional features when decoding to PCM

Support the following features useful when decoding a compressed
asset to PCM:
- GetDuration in SLPlayItf
- implemented SLMetadataExtractionItf on an AudioPlayer whose
data sink is a buffer queue (i.e. it's a decoder)
- added support for 6 new metadata keys that can be queried
through SLMetadataExtractionItf, which match the fields
of the SLDataFormat_PCM structure.
Updated the decode sample code to use these features: the
slesTestDecodeToBuffQueue app now displays:
- the number of channels
- the channel mask
- the sample size
- the container size
- the sample rate
- the format endianness

The SfPlayer class was implementing URI and FD decode and playback
in the application process. This CL removes this class entirely
and moves its functionality under the GenericPlayer class. This
means that the playback of URIs and FDs is now implemented through
an android::MediaPlayer object running in the media service.

The SfPlayer header had many StageFright and system includes, which
are now moved to the relevant files where they are required,
instead of automagically coming from sles_allinclusive.h.

Note that this CL breaks support for the following OpenSL ES features
due to missing Android MediaPlayer features:

Support for those features will be reintegrated in subsequent CLs.

In classes.h: we should only have to include the headers
for the objects that are actually stored as member variables of
the OpenSL ES and OpenMAX AL objects (so here AudioTrackProtector,
Effect, and GenericPlayer).
In CMediaPlayer.c: remove useless includes and change the video
surface function prototypes to use const refs to strong pointers
instead of pointers to access the GenericMediaPlayer objects.

Note that android_SfPlayer.h is still in sles_allinclusive.h because
it will be dealt with when the SfPlayer functionality is absorbed
under LocAVPlayer.

Created a new audio player class, APlayer, from which we derive
subclasses to encapsulate OpenSL ES AudioPlayer implementations:
- ASfPlayer derives from APlayer and encapsulates StageFright
functionality for audio decoding to a buffer
- ADecoder derives from ASfPlayer and encapsulates rendering
the decoded audio data to a callback function. It interfaces
with the OpenSL ES Buffer Queue interface to pass the decoded
data back to an OpenSL ES application.

For OpenSL ES, to support decoding to a Buffer Queue, we now
allow an AudioPlayer to have its sink be a PCM buffer queue.
