* audiopolicy: Add AudioSessionInfo APISteve Kondik2016-04-271-0/+42
| | | | | | | | | | | | | | | | * This patch introduces a new API which allows applications to query the state of the audio effects system, and receive callbacks with the necessary information to attach effects to any stream. * In the future, this may come as part of the AudioPort system, but since that's an active area of development by Google, we will dodge it for now. * The policy now simply keeps a refcounted list of objects which hold various bits of stream metadata. Callbacks are sent on stream open/close to applications which might be listening for them. Change-Id: I2d554d36e1378f4eb7b276010a3bfe8345c22ecd

* audiopolicy: Add notification when default effects are updatedSteve Kondik2016-03-081-0/+20
| | | | | | | | | | | | | | | | | | | * In M, we now have the ability to define a default set of audio effect on a per-stream basis. This allows us to get around the problem of apps not sending the control intents so we can implement smart global effects for specific media types. * We still need a session id in order to get a handle and configure them from an app like AudioFX, so we'll need to add some plumbing in order to send an event to interested applications. * This patch implements the native side of this. The Java layer will call down thru AudioSystem and register a callback which will be invoked by the audio policy when default effects are updated on a stream. This callback will receive both the stream type as well as the session id. * Attaching this listener requires that the caller hold the MODIFY_AUDIO_ROUTING permission.

* reduce number of binder calls from mediaserverEric Laurent2015-06-261-1/+16
| | | | | | | | | | | | | | | Reduce the number of audio port, audio patch and IO config changed binder calls from mediaserver to client processes: - Do not call IO config changed callback if selected device is the same as previously selected one on a given audio flinger playback or capture thread. - Do not call the audio port or audo patch list update callback on a client if this client as no listener registered.

* audio policy: session routes continued.Eric Laurent2015-04-301-2/+8
| | | | | | | | | | | - Clear session routes when client process dies. - Enforce the route only when the requesting session is active. - Fix requested route not working if an output mix change is required (e.g forcing to SPEAKER when the default route is USB or A2DP). - Make sure all sessions sharing the strategy with a rerouted session have the same route (needed for volume control consistency) Change-Id: I0ab347a8fb97e73e2c5965374544c5f4fe509ef1

* libmedia: offloaded playback supportRichard Fitzgerald2013-07-251-5/+27
| | | | | | | | | | | | | | | | | | | | | | | | | - start() returns a status so that upper layers can recreate a non offloaded track in case of error. - Added states to handle offloaded tracks specific: - waiting for stream end (drain) notification by audio flinger - allow pause while waiting for stream end notification - getPosition() queries the render position directly from audio HAL. - disable APIs not applicable to offloaded tracks - Modified track restoring behavior for invalidated offloaded tracks: just send the callback and wait for upper layers to create a new track. - Added wait for stream end management in audio track client proxy. Similar to obtainBuffer and should be factored in. Change-Id: I0fc48117946364cb255afd653195498891f622bd Signed-off-by: Eric Laurent <elaurent@google.com>
* Public API changes for audio offload support.Richard Fitzgerald2013-06-271-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | 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
