Public Methods

void ~AudioCore ()
void CreateAudioRenderer (::fidl::InterfaceRequest< ::fuchsia::media::AudioRenderer> audio_out_request)

Creates an AudioRenderer which outputs audio to the default device.

void CreateAudioCapturerWithConfiguration (::fuchsia::media::AudioStreamType stream_type, ::fuchsia::media::AudioCapturerConfiguration configuration, ::fidl::InterfaceRequest< ::fuchsia::media::AudioCapturer> audio_capturer_request)

Creates an AudioCapturer according to the given requirements.

`pcm_stream_type` sets the stream type of the stream to be delivered.

It causes the source material to be reformatted/resampled if needed

in order to produce the requested stream type.

`usage` is used by Fuchsia to make decisions about user experience.

See `AudioCaptureUsage` for more details.

`configuration` must be initialized to a variant, or no capturer

can be created.

void CreateAudioCapturer (bool loopback, ::fidl::InterfaceRequest< ::fuchsia::media::AudioCapturer> audio_in_request)

Creates an AudioCapturer which either captures from the current default

audio input device, or loops-back from the current default audio output

device based on value passed for the loopback flag.

void SetRenderUsageGain (::fuchsia::media::AudioRenderUsage usage, float gain_db)

Sets the gain for this render usage. By default, all render usages are set to Unity (0 db).

void SetRenderUsageGain2 (::fuchsia::media::AudioRenderUsage2 usage, float gain_db)

Sets the gain for this render usage. By default, all render usages are set to Unity (0 db).

void SetCaptureUsageGain (::fuchsia::media::AudioCaptureUsage usage, float gain_db)

Sets gain for this capture usage. By default, all capture usages are set to Unity (0 db).

void SetCaptureUsageGain2 (::fuchsia::media::AudioCaptureUsage2 usage, float gain_db)

Sets gain for this capture usage. By default, all capture usages are set to Unity (0 db).

void BindUsageVolumeControl (::fuchsia::media::Usage usage, ::fidl::InterfaceRequest< ::fuchsia::media::audio::VolumeControl> volume_control)

Binds to a volume control protocol for the given usage.

void BindUsageVolumeControl2 (::fuchsia::media::Usage2 usage, ::fidl::InterfaceRequest< ::fuchsia::media::audio::VolumeControl> volume_control)

Binds to a volume control protocol for the given usage.

void GetVolumeFromDb (::fuchsia::media::Usage usage, float gain_db, GetVolumeFromDbCallback callback)

Queries the volume percentage [0, 1] that maps to a `gain_db` value for a particular

`usage`. This is the same mapping as used by the VolumeControl from

`BindUsageVolumeControl`.

void GetVolumeFromDb2 (::fuchsia::media::Usage2 usage, float gain_db, GetVolumeFromDb2Callback callback)

Queries the volume percentage [0, 1] that maps to a `gain_db` value for a particular

`usage`. This is the same mapping as used by the VolumeControl from

`BindUsageVolumeControl`.

void GetDbFromVolume (::fuchsia::media::Usage usage, float volume, GetDbFromVolumeCallback callback)

Queries the decibel value that maps to a volume percentage [0, 1] for a particular `usage`.

This is the same mapping as used by the VolumeControl from `BindUsageVolumeControl`.

void GetDbFromVolume2 (::fuchsia::media::Usage2 usage, float volume, GetDbFromVolume2Callback callback)

Queries the decibel value that maps to a volume percentage [0, 1] for a particular `usage`.

This is the same mapping as used by the VolumeControl from `BindUsageVolumeControl`.

void SetInteraction (::fuchsia::media::Usage active, ::fuchsia::media::Usage affected, ::fuchsia::media::Behavior behavior)

Sets how audio_core handles interactions of multiple active streams simultaneously. If

streams of Usage `active` are processing audio, and streams of Usage `affected` are as well,

the Behavior specified will be applied to the streams of Usage `affected`.

void SetInteraction2 (::fuchsia::media::Usage2 active, ::fuchsia::media::Usage2 affected, ::fuchsia::media::Behavior behavior)

Sets how audio_core handles interactions of multiple active streams simultaneously. If

streams of Usage `active` are processing audio, and streams of Usage `affected` are as well,

the Behavior specified will be applied to the streams of Usage `affected`.

void ResetInteractions ()

Re-initializes the set of rules that are currently governing the interaction of streams in

audio_core. The default behavior is 'NONE'.

void LoadDefaults ()

Re-loads the platform policy configuration. Falls back to a default config if the platform

does not provide a config.
