* IAudioFlinger::openRecord returns IMemory(s)Glenn Kasten2014-05-091-0/+2
| | | | | | | | openRecord() now explicitly returns the control block and data buffer as separate IMemory references. If the IMemory for data buffer is 0, this means it immediately follows the control block. Change-Id: Ic098f88f0e037f8fbe30006689e18cacacf09d06
* Remove name output parameter from createTrackGlenn Kasten2014-03-141-4/+0
| | | | | | | It was only used for one log. A better solution will be a per-track unique ID. Change-Id: Ia440e02ae4a5a4019a9a2d08970e1ee93ac4c3a3

* | | AudioRecord::getInputFramesLost() cleanupGlenn Kasten2014-01-141-1/+1
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixed bug that if the binder call failed (for example if the IAudioFlinger binder is dead), then getInputFramesLost was returning garbage. Now it correctly returns zero, which is the error value for this method. The type declarations for getInputFramesLost were inconsistent: a mixture of unsigned int, size_t, and uint32_t. Now it returns uint32_t everywhere, which is what the underlying HAL API returns. Added a FIXME about the side effect behavior. This will need review for multi-client.

* Public API changes for audio offload support.Richard Fitzgerald2013-06-271-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | In IAudioFlinger::createTrack() and IAudioFlinger::openRecord(), declare input parameter to use correct type audio_channel_mask_t. In IAudioFlinger::getInputBufferSize(), input parameter is now channel mask instead of channel count. Remove unused IAudioFlinger::channelCount(audio_io_handle_t). In AudioRecord::getMinFrameCount() and AudioSystem::getInputBufferSize(), input parameter is channel mask instead of channel count. Change-Id: Ib2f1c29bea70f016b3cfce83942ba292190ac965

* audio policy: load audio hw modules.Eric Laurent2012-04-041-11/+15
| | | | | | | | | | | Audio HW modules are now loaded upon request from audio policy manager according to the configuration in audio_policy.conf. Removed hard coded HW module loading by AudioFlinger at init time. Added methods to IAudioFlinger and AudioPolicyInterface to control the loading of audio HW modules. Added methods to open an output or input stream on a specific hw module. Change-Id: I361b294ece1a9b56b2fb39cc64259dbb73b804f4

* IAudioFlinger::createTrack and openRecord flagsGlenn Kasten2012-03-191-3/+9
| | | | | | | | | | | | | | | | | | | | createTrack and openRecord don't need the "old" flags parameter, which was either audio_policy_output_t or audio_in_acoustics_t shifted left by 16 bits. But they do need "new" flags, which are defined by the application use case. Initially, the only application use case flag is timed output, but others are planned. For output, the audio_policy_output_t flags are passed to AudioSystem::getOutput, which returns an audio_io_handle_t, and that handle is then passed to createTrack. So createTrack doesn't need the old flags parameter. For input, the audio_in_acoustics_t flags are passed to AudioSystem::getInput, which returns an audio_io_handle_t, and that handle is then passed to openRecord. So openRecord doesn't need the old flags parameter. Change-Id: I18a9870911846cca69d420c19fe6a9face2fe8c4

* Keep effects sessions active when the caller dies.Marco Nelissen2011-08-091-0/+3
| | | | | | | | Don't remove effects until the session they are in goes away or all AudioEffects have been explicitly released. This allows the control panel process to die without stopping the effects. Change-Id: I4496e5df080230ca1af149dec95c1309ab8ea888
* Use channel mask instead of channel count for track creationJean-Michel Trivi2011-06-011-5/+5
| | | | | | | | | | | | | | | | | Record and playback objects (resp AudioRecord and AudioTrack) are created using a channel mask, but this information is lost in the mixer because only the channel count is known to AudioFlinger. A channel count can always be derived from a channel mask. The change consists in: - disambiguiting variable names for channel masks and counts - passing the mask information from the client to AudioFlinger and the mixer. - when using the DIRECT ouput, only verifying the format of the track is compatible with the output's for PCM.

* New effect library APIEric Laurent2011-05-271-1/+1
| | | | | | | | | | | | | | | | | Moved and renamed media/EffectApi.h to hardware/audio_effect.h Modified the effect library API to expose a library info structure containing an interface functions table. Also removed enums for audio channels, audio format and devices from effect API and use values from system/audio.h instead. Modified effects factory to support new library interface format and load libraries and efffects listed in audio_effects.conf file. The file audio_effects.conf is first loaded from /vendor/etc and then from /system/etc/audio_effects.conf if not found. Modified existing effect libraries to implement the new library interface.

* Fix issue 3371080Eric Laurent2011-02-031-3/+0
| | | | | | | | | | | | | | | | | | | | | | Modified default volume control logic in AudioService: 1 IN_CALL volume if in video/audio chat 2 NOTIFICATION if notification is playing or was playing less than 5s ago. 3 MUSIC Modified silent mode: - now also affect MUSIC stream type - entering silent mode when VOL- hard key is pressed once while selected stream volume is already at 0 (except for VOICE_CALL stream). - exiting silent mode when pressing VOL+ hard key while in silent mode Play sound FX (audible selections, keyboard clicks) at a fixed volume. Modified audio framework: - isStreamActive() method now implemented in AudioPolicyManagerBase (previously AudioFlinger) - iStreamActive() now specifies a time window during which the stream is considered active after it actually stopped. Change-Id: I7e5a0724099450b9fc90825224180ac97322785f
* Audio policy manager changes for audio effectsEric Laurent2010-07-201-0/+2
| | | | | | | | | | | | | | | Added methods for audio effects management by audio policy manager. - control of total CPU load and memory used by effect engines - selection of output stream for global effects - added audio session id in parameter list for startOutput() and stopOutput(). this is not used in default audio policy manager implementation. Modifications of audio effect framework in AudioFlinger to allow moving and reconfiguring effect engines from one output mixer thread to another when audio tracks in the same session are moved or when requested by audio policy manager. Also fixed mutex deadlock problem with effect chains locks. Change-Id: Ida43484b06e9b890d6b9e53c13958d042720ebdb
