Main stuff
- Delayed construction of audio player until after sample rate and
channels have been read from the first callback.
- Removed all sample rate and channels from outward facing api.
- Remove pause playing and prefetch duration and sample rate hacky code.
- Fixes handling of any sample rate by removing switch statement.
- Fixes a HORRIBLE bug introduced in last cl where I was creating the
callback context on the stack inside a method call, and using it a
pointer to it long after the object had been erased from the stack.
[worse yet: it still mostly worked fine!]
Other
- Fixes an obvious failure case of all tests - duh - I was calling setUp()
before setting the executor properly, so they were giving NPEs.
- Correct calculation of totalDuration now done on first decode callback.
- This will let us remove MediaPlayer from prepare() in follow up.
- Initializing the engine outside of the PlaybackRunnable, is cleaner.
- Adds static methods for reading duration and position, again so that
follow up can have accurate get current position rather than best guess.
- Buffers in use for decoding also not created until first decode callback.
- Introduces some wicked-cool OpenSL macro to log api calls, make the
api calls and check the result value.

The test changes:
- Adds many, many test cases against a MediaPlayerProxy, checking that
it behaves to the contract of a MediaPlayer.
- Adds the RealMediaPlayer class to check a real MediaPlayer.
- Adds the VariableSpeed class, to check a VariableSpeed instance
against the same contract as the MediaPlayer.
- Adds an Android.mk for the unit tests.
- Adds also an AndroidManifest.xml for the unit tests.
- Adds some test asset media files (3gpp file and mp3 file).
Required for the test changes:
- Adds a DynamicProxy class to adapt a MediaPlayer as a
MediaPlayerProxy class, i.e. to test the implementation of
MediaPlayerProxy, required to avoid writing an adapter.
- Adds a couple of listeners, OnErrorListener and
OnCompletionListener, that can be waited for synchronously in unit
tests.
Improvements as a result of the tests:
- During the testing, fixes the case where we weren't throwing
IllegalStateException if asked for the duration on released player.
- Refactored the create engine, create and realize output mix, create
and realize audio player, get play interfaces and callbacks, all
separated into their own static methods.
- This allows me to create the audio player during the main while loop
actually after the decoding has begun rather than before starting.
This work is a precursor to using the decoder's report on sample rate
and channels as the input to these methods.
- slSampleRate and slOutputChannels no longer computed in the
constructor, but computed when needed in the construction and
realization of the audio player.
Other changes:
- Remove some overly verbose logs on getDuration() and
getCurrentPosition().
- Adding the decoder interface to the callback.
- Extract metadata from decoder method now takes the metadata
interface, so this will be usable from the decoder callack in a follow
up.
- Temporarily stop getting the metadata out of the decoder, I'm going
to be doing it on the decoding callback instead.
- Renames the comment in AndroidManifest.xml to describe the
correct invocation to run the common tests.

Contains an implementation of time-domain audio scaler, for
pitch-invariant speed up and slow-down of audio.
Contains wrapper library using OpenSLES to pump audio from
encoded stream (mp3 file etc) through audio decoder then
through time scaler and out to media player.
This is written as a jni library with jni hooks to allow
driving of this from the Java side.
The other part of this cl is the Java wrapper. There is a
new interface MediaPlayerProxy, containing a subset of the
methods found on the MediaPlayer. The VariableSpeed class
provides a concrete implementation of this interface
adapting to the jni code.
