d6cdd7f7efdce16fc321f11bf5a3f88b3f28e244 03-Sep-2011 Glenn Kasten <gkasten@google.com> Decode to buffer queue test updates

Decrease frequency of decoder PCM buffer queue callback;
only display a line every 1000 PCM buffers.
Check result code returned by GetFillLevel and GetPrefetchStatus.
Share common call to GetPosition in DecProgressCallback for all HEAD* events.
Print error messages to stderr.

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.


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.

Declare in a public header the metadata keys an application which
decodes audio data would use to figure out the output PCM format.

Make the SL ES Android header also include the configuration and
metadata headers.
Update test apps to reflect this.

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.

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

Bug in detecting write errors: count and size in fwrite were
swapped, so an error was always reported.
