| * When passing a size_t via binder, use 64-bits unconditionallyGlenn Kasten2014-02-131-2/+2
| | | | | | | | | | | | | | | | | | 64-bits is almost always over-kill. But it's easier and cleaner to change the binder code to be accurate, than to rename all the the API parameter types to be 32-bit. Bug: 12381724 Change-Id: Ib8f198d814a2027760ef24e9e3feacee21a973b1

* fix volume and effect enable delay on offloaded tracksEric Laurent2013-09-301-0/+12
| | | | | | | | | | | | | Volume: add a method to wake up the mediaserver playback thread when a volume command is received on an offloaded track. Effects: call effect chain process on offloaded playback threads asynchronously from writes to allow effect state updates while waiting for async write callback. Bug: 10796540.

* Public API changes for audio offload support.Richard Fitzgerald2013-06-271-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Change-Id: I3ab41138aa1083d81fe83b886a9b1021ec7320f1 Signed-off-by: Richard Fitzgerald <rf@opensource.wolfsonmicro.com> Signed-off-by: Eric Laurent <elaurent@google.com>

* Whitespace and indentationGlenn Kasten2012-03-131-15/+15
| | | | | | | | | | | | | | Fix indentation to be multiple of 4. Make it easier to search: sp< not sp < to "switch (...)" instead of "switch(...)" (also "if" and "while") Remove redundant blank line at start or EOF. Remove whitespace at end of line. Remove extra blank lines where they don't add value. Use git diff -b or -w to verify.

* Issue 2667801: [Audio Effect Framework] AudioFlinger, AudioMixer AudioTrack ↵Eric Laurent2010-06-031-2/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | modifications. First drop of audio framework modifications for audio effects support. - AudioTrack/AudioRecord: Added support for auxiliary effects in AudioTrack Added support for audio sessions Fixed left right channel inversion in setVolume() - IAudioFlinger: Added interface methods for effect enumeraiton and instantiation Added support for audio sessions. - IAudioTrack: Added method to attach auxiliary effect. - AudioFlinger Created new classes to control effect engines in effect library and manage effect connections to tracks or output mix: EffectModule: wrapper object controlling the effect engine implementation in the effect library. There is one EffectModule per instance of an effect in a given audio session EffectChain: group of effects associated to one audio session. There is one EffectChain per audio session. EffectChain for session 0 is for output mix effects, other chains are attached to audio tracks with same session ID. Each chain contains a variable number of EffectModules EffectHandle: implements the IEffect interface. There is one EffectHandle object for each application controlling (or using) an effect module. THe EffectModule maintians a list of EffectHandles. Added support for effect modules and effect chains creation in PlaybackThread. modified mixer thread loop to allow track volume control by effect modules and call effect processing. -AudioMixer Each track now specifies its output buffer used by mixer for accumulation Modified mixer process functions to process tracks by groups of tracks with same buffer Modified track process functions to support accumulation to auxiliary channel Change-Id: I26d5f7c9e070a89bdd383e1a659f8b7ca150379c
* Fix issue 2203561: Sholes: audio playing out of earpiece.Eric Laurent2009-11-041-2/+11
| | | | | | | | | | | Create a new IAudioTrack interface to AudioFlinger when start() fails due to a broken pipe error. Do the same if start fails due to the same error after time out in obtainBuffer(). Do not indicate that the AudioTrack is started to AudioPolicyManager if IAudioTrack start fails. This avoids that an AudioTrack keeps a dead IAudioTrack after a media server crash. Same modifications for AudioRecord. Add a flag to ToneGenerator indicating that the callback thread can call Java. Without it, when the media server crashes and restarts, the AudioSystem error callback will crash in JNI if the IAudiotrack is created from AudioTrack callback thread.
* Fix issue 2107584: media server crash when AudioFlinger fails to allocate ↵Eric Laurent2009-09-091-2/+6
| | | | | | | | memory for track control block. AudioFlinger: verify that mCblk is not null before using it in Track and RecordTrack contructors. IAudioFlinger: check result of remote transaction before reading IAudioTrack and IAudioRecord. IAudioTrack and IAudioRecord: check result of remote transaction before reading IMemory.
* some work to try to reduce the code size of some native librariesMathias Agopian2009-05-261-6/+0
| | | | | | | | | | | | | | | | | - make sure that all binder Bn classes define a ctor and dtor in their respective library. This avoids duplication of the ctor/dtor in libraries where these objects are instantiated. This is also cleaner, should we want these ctor/dtor to do something one day. - same change as above for some Bp classes and various other non-binder classes - moved the definition of CHECK_INTERFACE() in IInterface.h instead of having it everywhere. - improved the CHECK_INTERFACE() macro so it calls a single method in Parcel, instead of inlining its code everywhere - IBinder::getInterfaceDescriptor() now returns a "const String16&" instead of String16, which saves calls to String16 and ~String16 - implemented a cache for BpBinder::getInterfaceDescriptor(), since this does an IPC. HOWEVER, this method never seems to be called. The cache makes BpBinder bigger, so we need to figure out if we need this method at all.
