Add the possibility for apps to indicate that their
capture use case is private and that a privileged Assistant
should not be able to capture concurrently.
This allows to override the default behavior tied to the audio
source (e.g VOICE_COMMUNICATION is private by default but
UNPROCESSED is not).
- Add AAudio API to set and get privacy sensitive mode on input stream
- Add MediaRecorder API to set and get privacy sensitive mode
- Modify AudioSource constructor to accept audio attributes instead of an
audio source to specify the use case.
- Modify audio policy concurrent capture logic to use audio attributes
flag instead of audio source to decide of a capture client has
requested privacy mode or not.

1. Toggling between Treble and non-Treble OMX will now be controlled by
two properties: "persist.hal.binderization" and
"persist.media.treble_omx". (Before this CL, this was controlled by
"debug.treble_omx".)
- If persist.media.treble_omx is not set, it will assume a default value
of -1.
- If persist.media.treble_omx is -1, persist.hal.binderization will be
used to determine whether OMX will be created as a Treble or non-Treble
service.
- If persist.media.treble_omx is 1, OMX will be created as a Treble
service.
- If persist.media.treble_omx has any other value, OMX will be created
as a non-Treble service.
- persist.media.treble_omx can be changed without rebooting, but it will
only take effect after media.codec and mediaserver processes are killed.
2. Remove all dependencies on non-Treble service. This was not done for
MediaCodec, MediaPlayerService::Client, MediaRecorderClient, stagefright
command, and omx_tests command. OMXClient and media.codec process will
now pick the right version of OMX based on properties mentioned above.
Before this CL, media.codec would always present the non-Treble version
of OMX regardless of the flag.
3. Provide workarounds for some HIDL issues.
- A sequence of nested binder and hwbinder calls require many threads to
handle. (b/35283480) The workaround is to increase the number of threads
in the thread pool of media.codec process.
- android.hidl.base@1.0::IBase::unlinkToDeath takes a strong pointer
instead of a weak pointer. (b/35233970) This causes an infinite
recursion in the destructor of ServiceDeathNotifier in
MediaPlayerService::Client and MediaRecorderClient. The workaround moves
calls to unlinkToDeath() outside of the destructor.
Test: Recorded and played videos with Camera app. Ran stagefright and
omx_tests commands.

- Create GraphicBufferSource in IOMX regardless of persistency.
- Remove createInputSurface on IOMXNode, only keep setInputSurface
which accepts either a persistent or non-persistent surface.
- Instead of holding a IGraphicBufferConsumer, hold
IGraphicBufferSource across session as the persistent surface.
- Fix up GraphicBufferSource to allow usage across sessions.
GraphicBufferSource itself becomes agnostic to persistency.
- Remove max encoder input buffers profiling code.

Making a connection from MediaRecorder Native layer to the
SurfaceMediaSource for the purpose of encoding GL Frames. This will be
called from the java side inside the Mobile Filter Framework.
The mediarecorder native layer (client), when set the videosource to
option VIDEO_SOURCE_FRAMES, asks the StageFrightRecorder on the mediaserver
side to create a SurfaceMediaSource object and pass it back as a
sp<ISurfaceTexture> object. Using that, the client side will dequeue and
queue buffers. Connecting the GL Frames to the obtained
sp<ISurfaceTexture> is not part of this CL.

The purpose of ICameraRecordingProxy and ICameraRecordingProxyListener is to
allow applications using the camera during recording.
Camera service allows only one client at a time. Since camcorder application
needs to own the camera to do things like zoom, the media recorder cannot
access the camera directly during recording. So ICameraRecordingProxy is a proxy
of ICamera, which allows the media recorder to start/stop the recording and
release recording frames. ICameraRecordingProxyListener is an interface that
allows the recorder to receive video frames during recording.
ICameraRecordingProxy
startRecording()
stopRecording()
releaseRecordingFrame()
ICameraRecordingProxyListener
dataCallbackTimestamp()
The camcorder app opens the camera and starts the preview. The app passes
ICamera and ICameraRecordingProxy to the media recorder by
MediaRecorder::setCamera(). The recorder uses ICamera to setup the camera in
MediaRecorder::start(). After setup, the recorder disconnects from camera
service. The recorder calls ICameraRecordingProxy::startRecording() and
passes a ICameraRecordingProxyListener to the app. The app connects back to
camera service and starts the recording. The app owns the camera and can do
things like zoom. The media recorder receives the video frames from the
listener and releases them by ICameraRecordingProxy::releaseRecordingFrame.
The recorder calls ICameraRecordingProxy::stopRecording() to stop the
recording.
The call sequences are as follows:
1. The app: Camera.unlock().
2. The app: MediaRecorder.setCamera().
3. Start recording
(1) The app: MediaRecorder.start().
(2) The recorder: ICamera.unlock() and ICamera.disconnect().
(3) The recorder: ICameraRecordingProxy.startRecording().
(4) The app: ICamera.reconnect().
(5) The app: ICamera.startRecording().
4. During recording
(1) The recorder: receive frames from ICameraRecordingProxyListener.dataCallbackTimestamp()
(2) The recorder: release frames by ICameraRecordingProxy.releaseRecordingFrame().
5. Stop recording
(1) The app: MediaRecorder.stop()
(2) The recorder: ICameraRecordingProxy.stopRecording().
(3) The app: ICamera.stopRecording().

This change makes the camera HAL interface take an ANativeWindow interface from
which all the camera preview buffers will be allocated. The framework code
running in application processes now passes a Surface object rather than an
ISurface to the camera server via Binder when setting the preview surface. The
camera server then forwards that Surface object (which implements the
ANativeWindow interface) to the camera HAL, which uses it to communicate with
SurfaceFlinger to allocate the camera preview buffers.

- An alternative would be to define a common base class that
both MediaRecorderClient and MediaPlayerClient can derive.
But since the common code, onTransact() and notify() uses
some Binder code, having a common base class may not gain
us too much in terms of code reuse.
