* audio: Add audio parameter key for device connectHaynes Mathew George2015-01-311-0/+1
| | | | | | | | | Add audio parameter key for device connect. Bug: 17785277 Bug: 19214836 Change-Id: Icd81702634e0bd83645d89c2d65e2b303fc11f8c (cherry picked from commit 55c07c3418a3bc19a72c4935d8ed57a57074c49a)
* audio: new parameter key for HW A/V sync ID allocationEric Laurent2014-10-201-3/+5
| | | | | | | | | | | The HW A/V sync ID is retrieved from the HAL by calling global get_parameters() with key AUDIO_PARAMETER_HW_AV_SYNC. After the output stream is opened, the HW A/V sync ID is communicated by stream set_parameters() with key AUDIO_PARAMETER_STREAM_HW_AV_SYNC. Bug: 17112525.

* audio: audio HAL extension for routing and volume controlEric Laurent2014-05-221-1/+34
| | | | | | | | | | | | | | Added audio HAL functions to control audio routing and audio gain. Audio HALs above version 3.0 must implement these functions. These functions will be used by the framework instead of out_set_parameters("routing"=XXX) for device selection on an output or input stream. They will also allow direct connection of input devices to output devices as well as gain control on devices or streams. The gain or routing capabilities are exposed in audio_polciy.conf file.

* audio HAL: add minimum supported versionEric Laurent2014-05-221-0/+2
| | | | | | | Add a definition for the minimum audio HAL version supported by the audio framework. Change-Id: Id7df440cc9fcc23b27b61c81bacb569599a20c13
* Described restrictions for common HAL object methods.Stewart Miles2014-05-121-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Inheritance of HAL object is performed by composing a child structure of a single parent structure located at offset 0 followed by new data members and function pointers in the child structure. For example, struct child { struct parent common; int a_data_member; void (*a_method)(struct child *c, int v); }; HAL code assumes this layout when accessing child structures given a pointer to a parent structure such that users write code like the following... void child_method(struct *parent, int v) { struct child * c = (struct child*)parent; // do stuff with c } Code above will break if a member is added before "common" in "struct child". This change adds comments that describe the restriction on the location of parent HAL objects within a derived HAL object. HAL objects that already have comments that describe the required location of parent objects are not modified. Change-Id: Ibe4300275286ef275b2097534c84f1029d761d87

* Add defines and support for audio offloadRichard Fitzgerald2013-06-271-11/+104
| | | | | | | | | | | | | | | | - Add non-blocking write support, set_callback() function - Add pause, resume, flush, drain functions to audio output stream - Add audio parameter defines for compressed audio metadata - Extend audio_config_t to include an audio_offload_info_t field - Add is_offload_supported() function to test whether there is hardware decode support for a given compressed audio format - Change audio_stream_frame_size() to handle offloaded streams. For an offloaded stream the size is always counted in bytes (frame size == 1) and the number of channels is irrelevant.

* audio: new audio devices enumsEric Laurent2012-09-071-1/+8

* Add audio module for remote submixJean-Michel Trivi2012-09-061-0/+1
| | | | | | | | | | | | | New definitions of audio devices for remote submix: one representing a sink for writing the audio buffers that won't be played directly locally, another representing the audio source that can be read from to obtain the audio mix. New audio hardware module encapsulating the submix loop functionality. Create a Pipe to serve as non-blocking audio ring buffer between the output device (the sink) and the input device (the source).
