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

* Fix issues with synchronous record start.Eric Laurent2012-05-141-0/+4
| | | | | | | | | | | | | | | | - Added a timeout in case the trigger event is never fired. - Extend AudioRecord obtainBuffer() timeout in case of synchronous start to avoid spurious warning. - Make sure that the event is triggered if the track is destroyed. - Reject event if the triggering track is in an incompatible state. Also fix a problem when restoring a static AudioTrack after a mediaserver crash. Bug 6449468. Change-Id: Ib36e11111fb88f73caa31dcb0622792737d57a4b

* audio policy: add configuration fileEric Laurent2012-04-031-0/+13
| | | | | | | | | | | removed outputs to stream mapping cache in audio system: the output for a given stream type must always be queried from audio policy manager as the cache is not always updated fast enough by audioflinger callback. removed AudioFlinger::PlaybackThread::setStreamValid() not used anymore if stream to output mapping is not cached.

* implemented synchronous audio captureEric Laurent2012-03-291-0/+15
| | | | | | | | | | | | | | Added the infrastructure to support the synchronization of playback and capture actions on specific events. The first requirement for this feature is to synchronize the audio capture start with the full rendering of a given audio content. The applications can further be extended to other use cases (synchronized playback start...) by adding new synchronization events and new synchronous control methods on player or recorders. Also added a method to query the audio session from a ToneGenerator. Change-Id: I51f1167290d9cafdf2fbcdf9e4785156973af44c

* Use audio_source_t consistentlyGlenn Kasten2012-01-261-1/+1
| | | | | | | | | | | | | | | | Was a mix of audio_source_t, uint8_t, and int. Related fixes: - fix comments in MediaRecorder.java - AudioPolicyService server side was not checking source parameter at all, so if the client wrapper was bypassed, invalid values could be passed into audio HAL - JNI android_media_AudioRecord_setup was checking source for positive values, but not negative values. This test is redundant, since already checked at Java and now checked by AudioPolicyService also, but might as well make it correct. Change-Id: Ie5e25d646dcd59a86d7985aa46cfcb4a1ba64a4a

| | | | | | | | | | | | Was int or uint32_t. When AudioFlinger::format can't determine the correct format, return INVALID rather than DEFAULT. Init mFormat to INVALID rather than DEFAULT in the constructor. Subclass constructors will set mFormat to the correct value. Change-Id: I9b62640aa107d24d2d27925f5563d0d7407d1b73

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Improve volume management by keeping track of volume for each type of device independently. Volume for each stream (MUSIC, RINGTONE, VOICE_CALL...) is now maintained per device. The main changes are: - AudioService now keeps tracks of stream volumes per device: volume indexes are kept in a HashMap < device , index>. active device is queried from policy manager when a volume change request is received initalization, mute and unmute happen on all device simultaneously - Settings: suffixes is added to volume keys to store each device volume independently. - AudioSystem/AudioPolicyService/AudioPolicyInterface: added a device argument to setStreamVolumeIndex() and getStreamVolumeIndex() to address each device independently. - AudioPolicyManagerBase: keep track of stream volumes for each device and apply volume according to current device selection.

Also fixed a couple of hard-coded -1 instead of AUDIO_STREAM_DEFAULT, and in startToneCommand a hard-coded 0 instead of AUDIO_STREAM_VOICE_CALL. Change-Id: Ia33bfd70edca8c2daec9052984b369cd8eee2a83
* 226483: A2DP connected, but music out to speakerEric Laurent2011-08-301-1/+6
| | | | | | | | | | | | | | | | When the A2DP headset is connected, there is a possible race condition when the audio tracks are moved from the mixer thread attached to the speaker output to the thread attached to A2DP output. As the request to clear the stream type to output mapping cache in the client process is asynchronous, it is possible that the flag indicating to the client audio track to re-create the IAudioTrack on the new thread is processed before the cache is invalidated. In this case, the track will be attached to the old thread and music will continue playing over the device speaker instead of being redirected to A2DP headset.

* Audio effects: track CPU and memory use separatelyEric Laurent2011-08-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | Before this change, CPU and memory usage for an audio effect were registered and checked against the limit by audio policy manager upon effect instantiation. Even if an effect was not enabled it would prevent another effect to be created if the CPU load budget was exceeded, which was too restrictive. This change adds a method to register/unregister CPU load only when an effect is enabled or disabled. It also adds a mechanism to place all effects on the global output mix in suspend state (disabled) when an effect is enabled on a specific session. This will allow applications using session effects to have the priority over others using global effects. Also fixes some issues with suspend/restore mechanism: - avoid taking actions when an effect is disconnected and was not enabled. - do not remove a session from the suspended sessions list when corresponding effect chain is destroyed.

* Keep effects sessions active when the caller dies.Marco Nelissen2011-08-091-0/+2
| | | | | | | | 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
* Audio framework: support for audio pre processingEric Laurent2011-07-181-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | Audio effect framework is extended to suport effects on output and input audio path. AudioFlinger: Support for audio effects and effect chains is moved from PlaybackThread class to ThreadBase class so that RecordThread can manage effects. Effects of type pre processing are allowed on record thread only. When a pre processing is enabled, the effect interface handle is passed down to the input stream so that the audio HAL can call the process function. The record thread loop calls the effect chain process function that will only manage the effect state and commands and skip the process function. AudioRecord: The audio session is allocated before calling getInput() into audio policy serice so that the session is known before the input theead is created and pre processings can be created on the correct session. AudioPolicyService: default pre processing for a given input source are loaded from audio_effects.conf file. When an input is created, corresponding effects are created and enabled.

* Add new audio mode for audio communications other than telelphony.Jean-Michel Trivi2010-11-161-0/+1
| | | | | | | | | | | | | | The audio mode MODE_IN_CALL signals the system the device a phone call is currently underway. There was no way for audio video chat or VoIP applications to signal a call is underway, but not using the telephony resources. This change introduces a new mode to address this. Changes in other parts of the system (java and native) are required to take this new mode into account. The generic AudioPolicyManager is updated to not use its phone state variable directly, but to use two new convenience methods, isInCall() and isStateInCall(int) instead.

* Audio policy manager changes for audio effectsEric Laurent2010-07-201-2/+25
| | | | | | | | | | | | | | | 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
* Various fixes and improvements in audio effects implementationEric Laurent2010-06-251-29/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Effect API: - Use different definitions for audio device, channels, formats... in AudioSystem and EffectApi: Removed media/AudioCommon.h file created for initial version of EffectApi - Indicate audio session and output ID to effect library when calling EffectCreate(). Session ID can be useful to optimize the implementation of effect chains in the same audio session. Output ID can be used for effects implemented in audio hardware. - Renamed EffectQueryNext() function to EffectQueryEffect() and changed operating mode: now an index is passed for the queried effect instead of implicitly querying the next one. - Added CPU load and memory usage indication in effects descriptor - Added flags and commands to indicate changes in audio mode (ring tone, in call...) to effect engine - Added flag to indicate hardware accelerated effect implementation. - Renamed EffectFactoryApi.h to EffectsFactoryApi.h for consistency with EffectsFactory.c/h Effect libraries: - Reflected changes in Effect API - Several fixes in reverb implementation - Added build option TEST_EFFECT_LIBRARIES in makefile to prepare integration of actual effect library. - Replaced pointer by integer identifier for library handle returned by effects factory Audio effect framework: - Added support for audio session -1 in preparation of output stage effects configuration. - Reflected changes in Effect API - Removed volume ramp up/down when effect is inserted/removed: this has to be taken care of by effect engines. - Added some overflow verification on indexes used for deferred parameter updates via shared memory - Added hardcoded CPU and memory limit check when creating a new effect instance Change-Id: I43fee5182ee201384ea3479af6d0acb95092901d
