Switched to SimpleDecodingSource from OMXSource, as we don't do
pause/seek.

Switched to tracking only the capability of the first video codec
for each type, as we only use the first one.

The channel mask validation code had a number of built-in
assumptions around positional masks. Most of these assumptions
are invalid for indexed masks.

The translation between OpenSLES channel masks and Android
channel masks also needed reworking; this CL attempts to
do it the right way by calling helper functions rather than
setting bits directly.

mDuration is protected by mSettingsLock because it is accessed from both
the ALooper thread and from the application thread, but only one of the
two "set"s was using the lock, and the "get" was not using the lock.

Also added some comments about the lock, and moved lock closer inside { }.

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.

ddaf8fec2c6362785f8f27e59e30bf6bfe858f3b 03-Sep-2011 Glenn Kasten <gkasten@google.com> Bug 5262776 reliability of play event callbacks

This makes HEADMOVING and HEADATMARKER work more reliably, especially
at the beginning of track and under heavy load. Previously if an event
update was missed because update period is too small or mediaserver/client
is too busy to keep up with notifications, then subsequent events
were lost. This happened more than you might expect; the first event
was often lost and things just got worse from there.

Cleanup in AudioSfDecoder:
- Call up to superclass (GenericPlayer) onSeek and onLoop
to make future maintenance easier.
- Delete dead code in onMessageReceived.
- Logic depends on mLastDecodedPositionUs not being ANDROID_UNKNOWN_TIME
- Simplify getPositionUsec

Add more logging in GenericPlayer::updateOneShot.

0f92f48017588949daf7d24a339423e149bb2555 01-Sep-2011 Glenn Kasten <gkasten@google.com> Bug 5244675 PCM sample rate metadata units

The current metadata key macro name ANDROID_KEY_INDEX_PCMFORMAT_SAMPLESPERSEC
is confusing. This change renames it to ANDROID_KEY_INDEX_PCMFORMAT_SAMPLERATE,
and documents that it is in Hz rather than milliHz. The key string is
renamed from AndroidPcmFormatSamplesPerSec to AndroidPcmFormatSampleRate.

Details:

OpenSL ES 1.0.1 PCM struct SLDataFormat_PCM field samplesPerSec
[sic] is in milliHz. OpenSL ES 1.1 preserves that struct, but adds
struct SLDataFormat_PCM with field sampleRate also in milliHz. If the
ANDROID_KEY_INDEX_PCMFORMAT_* metadata keys were intended to exactly
model the OpenSL ES PCM data format struct, the metadata sample rate
would also be in milliHz units. However, the rest of Android operates
in Hz so we use Hz here also.

Backwards compatibility for the name should not be an issue,
as the initial beta developer has not yet started using this metadata.

Related change: delete a duplicate header file.

The metadata keys are now exposed for AAC decode.

The metadata keys are now exposed at Realize. The keys were previously
only available after prefetching was complete. This made it more awkward
for an application to use them.

As the media framework does not directly support marker and periodic
callbacks, we use a retriggerable one-shot timer at application level
to emulate this. This has the advantage of being faster, but is also
less accurate than if it were in the framework.

Details:
- Get position is now synchronous and (mostly) lock-free
- Fix regression in SL_PLAYEVENT_HEADATMARKER and SL_PLAYEVENTHEADATNEWPOS
- Fix SMP races in GetPlayState, GetCallbackEventsMask, GetMarkerPosition,
GetPositionUpdatePeriod
- AudioSfDecoder was not updating mPositionMsec when getPositionUsec failed
- Updating attributes is relatively expensive, so only do it when a significant change
in SetMarkerPosition, ClearMarkerPosition, SetPositionUpdatePeriod
- Error on unknown message type in onMessageReceived
- Delete an obsolete FIXME
- "Clearing" a marker is now equivalent to disabling the marker event,
and the default marker position is cleared.
- use Android time units and types (int32_t, ANDROID_UNKNOWN_TIME, etc.) where appropriate
instead of SLmillisecond and SL_TIME_UNKNOWN

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
issues INFO_FORMAT_CHANGED
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.

object, release the code buffer if necessary, to
ensure proper teardown of the audio source (OMXCodec)

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:
SLPlayItf.GetPosition
HEADATMARKER
HEADATNEWPOSITION
SLVolumeItf.EnableStereoPosition
SetStereoPosition
SLMuteSoloItf
SLPlaybackRateItf

Support for those features will be reintegrated in subsequent CLs.

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.

37dc2fccf3f122b79ebd554de209d0a3c94ae161 09-Mar-2011 Jean-Michel Trivi <jmtrivi@google.com> Bug 3329759 Implement streamInformation and volume in OpenMAX AL

- Implement StreamInformation for video size notification.
- Implement the XAVolumeItf for volume control
- Fix bug in GUID -> MPH hash.
- Fixed typo in GenericPlayer::pause() log
- Do not signal a discontinuity automatically when the ABQ is
cleared because clearing the queue doesn't imply there will
be a discontinuity in the data (e.g. the same data that was
cleared could be reenqueued)
- In "native-media" test app: add test code to exercise the
XAVolumeItf functionality.

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.
