Member Function Documentation

ChangeDevice()

virtual bool FVoiceCaptureOpenSLES::ChangeDevice ( const FString &  DeviceName, int32  SampleRate, int32  NumChannels  )

inlinevirtual

Change the associated capture device

Parameters

DeviceName	name of device to capture audio data with, empty for default device
SampleRate	sampling rate of voice capture
NumChannels	number of channels to capture

Returns

true if change was successful, false otherwise

NYI

Implements IVoiceCapture.
