Class AudioEncoder

AAC Class

Description

A class used to encode an audio data stream using AAC (Advanced Audio Codec) standard.

Syntax

class AAC

Members

Public Constructors
AAC::AAC	Constructs an AAC object.
Public Methods
AAC::configAudio	Configure AAC module by setting up audio configuration parameters.
AAC::begin	Start AAC module audio encoder.
AAC::end	Stop AAC module audio encoder.

AAC::configAudio

Description

Configure AAC module by setting up audio configuration parameters.

Syntax

void configAudio(AudioSetting& config);

Parameters

config: AudioSetting object containing desired audio configuration.

Returns

NA

Example Code

Example: Audio/RTSPAudioStream

Note

“AudioEncoder.h” must be included to use the class function.

G711E Class

Description

A class used to encode an audio data stream using ITU-T G.711 standard.

Syntax

class G711E

Members

Public Constructors
G711E::G711E	Constructs a G711E object.
Public Methods
G711E::configAudio	Configure G711E module by setting up audio configuration parameters.
G711E::configCodec	Configure G711E module companding algorithm.
G711E::begin	Start G711E module audio encoder.
G711E::end	Stop G711E module audio encoder.

G711E::configAudio

Description

Configure G711E module by setting up audio configuration parameters.

Syntax

void configAudio(AudioSetting& config);

Parameters

config: AudioSetting object containing desired audio configuration.

Returns

NA

Example Code

Example: Audio/RTPAudioStream

CODEC_G711_PCMA

Returns

NA

Example Code

Example: Audio/RTPAudioStream

Note

“AudioEncoder.h” must be included to use the class function. The G711E audio encoder will only work when the audio sample rate is configured as 8kHz or 16kHz.
