stagefright: offload playback support
Offloading of compressed audio decoding to audio DSP
is implemented for audio only, non streamed content.
when the datasource is
AudioPlayer:
- Create an offloaded sink when playing a compressed
source
- Send metadata to audio HAL
- Return sink start error to AwesomePlayer so that a
new player for PCM audio can be created in case of problem.
- Forward stream end and tear down callback events to AwesomePlayer
- Stop the sink and wait for stream end callback when EOS is reached.
- Pause and restart the sink if needed before flushing when seeking
(otherwise flush is a no op).
- For current media time, directly query the render position from the
sink and offset by the start position (seek to time)
AwesomePlayer:
- When initializing the audio decoder, check with audio policy manager
if offloading is supported. If yes, create the software decoder in
case a reconfiguration is needed but connect the audio track directly
to the AudioPlayer.
- In case of error when starting the AudioPlayer, reconnect the software
decoder (OMXSource) and recreate a PCM AudioPlayer.
- Handle AudioPlayer tear down event by detroying and recreating the
AudioPlayer to allow transitions between situations were offloading
is supported or not.
- Force tear down of offloaded AudioPlayer when paused for a certain time:
This will close the sink and allow the DSP to power down.
Utils:
- Added helper methods:
- send meta data to audio ia sink setParameters
- query audio policy manager if offloading is supported for a
given audio content

Public API changes for audio offload support.
NOTE: this does _not_ include all private member variables added
to classes as part of offload support. Only public/protected functions
and stubs functions/variables needed to make the changes buildable.
- isOffloadSupported() added to audio policy service
A stub implementation is required to build, this always returns false
- setParameters() added to IAudioTrack
A stub implementation is required to build, this always returns
INVALID_OPERATION
- CBlk flag for stream end
- Change AudioSystem::getRenderPosition() to take an audio_output_t
so caller can specify which output to query
- Add AudioSystem::isOffloadSupported()
This is fully implemented down to the AudioFlinger function
AudioPolicyServer::isOffloadSupported() which is just a stub
that always returns false.
- Add EVENT_STREAM_END to AudioTrack interface.
STREAM_END is used to signal when the hardware has actually finished
playing all the data it was sent.
- Add event type enumeration to media player interface AudioSink callbacks
so that the same callback can be used to handle multiple types of
event. For offloaded tracks we also have to handle STREAM_END and
TEAR_DOWN events
- Pass audio_offload_info_t to various functions used for opening outputs,
tracks and audio players. This passes additional information about the
compressed stream down to the HAL when using offload.
For publicly-available APIs this is an optional parameter (for some of
the internal and low-level APIs around the HAL interface it is mandatory)
- Add getParameters() and setParameters() API to AudioTrack
Currently dummy implementations.
- Change AudioPlayer contructor so that it takes a set of bitflags defining what
options are required. This replaces the original bool which only specified
whether to use deep buffering.
- Changes to StageFright class definition related to handling tearing-down of
an offloaded track when we need to switch back to software decode
- Define new StageFright utility functions used for offloaded tracks
Currently dummy implementations.
- AudioFlinger changes to use extended audio_config_t.
Fills in audio_offload_info_t member if this info is passed in when
opening an output.
- libvideoeditor changes required to add the new event type parameter
to AudioSink callback functions
- libmediaplayerservice changes required to add the new event type parameter
to AudioSink callback functions

Use sp<AudioTrack> instead of raw AudioTrack *
This change prepares for the new implementation of AudioTrack client, which
will require clients to use only sp<AudioTrack>, not raw AudioTrack *.
A raw delete will cause a race condition during AudioTrack destruction.
AudioTrack was made a RefBase by commit b68a91a70bc8d0d18e7404e14443d4e4020b3635
on 2011/11/15, when it was needed by OpenSL ES (for the callback protector).
At that time, the only other client that was also converted from
AudioTrack * to sp<AudioTrack> was android.media.AudioTrack JNI in
project frameworks/base (file android_media_AudioTrack.cpp).
Details:
* Use .clear() instead of delete followed by = NULL.
* ALOG %p need .get().
* sp<> don't need to be listed in constructor initializer, if initially 0.
* Use == 0 for sp<> vs == NULL for raw pointers.
* Use if (sp != 0) instead of if (raw).
