Struct CaptureProxy

pub struct CaptureProxy { /* private fields */ }

Implementations

impl CaptureProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.test.audio/Capture.

pub fn take_event_stream(&self) -> CaptureEventStream

Get a Stream of events from the remote end of the protocol.

Panics

Panics if the event stream was already taken.

pub fn start_output_capture( &self, ) -> QueryResponseFut<CaptureStartOutputCaptureResult, DefaultFuchsiaResourceDialect>

Start capturing the outgoing audio for this device.

A virtual output device receives what would have played through the device’s speakers. This method reads from that virtual output device, into an internal buffer.

After calling this method, use StopOutputCapture to stop recording output and then GetOutputAudio to retrieve this captured audio.

• response error description of failure action to take.

pub fn stop_output_capture( &self, ) -> QueryResponseFut<CaptureStopOutputCaptureResult, DefaultFuchsiaResourceDialect>

Stop capturing the outgoing audio for this device.

This method will succeed even if no output capture has been started.

After calling this method, use GetOutputAudio to retrieve the captured audio from the virtual device’s internal buffer and return it to the client.

• response error description of failure action to take.

pub fn get_output_audio( &self, ) -> QueryResponseFut<CaptureGetOutputAudioResult, DefaultFuchsiaResourceDialect>

Extract the captured outgoing audio data through a socket.

The socket is closed once it is fully drained.

User should have first called StartOutputCapture and StopOutputCapture. This method will return the contents of the internal buffer that was populated between the calls to those two methods.

Audio output format is 2-channel 48kHz 16-bit PCM.

• request audio_reader socket where full captured audio data will be streamed.

• response error description of failure action to take.
