Detailed Description

class for compressing audio to be sent over network

This class encapsulates opus encoder for packing audio over network. Future releases may include other options regarding the codec or type of input (audio/video/feeling/touch/smell/other?)

Member Function Documentation

frameEncoded

void AudioEncoder::frameEncoded ( quint32  aCallId, quint32  aSeqNo, const QByteArray &  aEncodedData, Hash  aForNode  )

signal

This signal is emitted after audio frame has been encoded into opus format. When audio data is sent in via slot frameReady then this signal is emitted as result of succesful processing.

Parameters

aCallId	call identifer of the audio stream
aSeqNo	sequence number of frame inside stream
aEncodedData	raw opus frame, as it comes out from opus library call opus_encode_float().
aForNode	fingerprint of node supposed to receive the frame

frameReady

void AudioEncoder::frameReady ( quint32  aCallId, quint32  aSeqNo, const QByteArray &  aAudioData, Hash  aForNode  )

slot

Input to encoder cames in via this method.

Parameters

aCallId	call identifer of the audio stream
aSeqNo	sequence number of frame inside stream
aAudioData	raw, unpacked audio samples. The byte-array must contain an array of floats in [-1,1] range.
aForNode	fingerprint of node supposed to receive the frame
