The QAudioEncoderSettings class provides a set of audio encoder settings.
A audio encoder settings object is used to specify the audio encoder settings used by QMediaRecorder. Audio encoder settings are selected by constructing a QAudioEncoderSettings object, setting the desired properties and then passing it to a QMediaRecorder instance using the QMediaRecorder::setEncodingSettings() function.
QAudioEncoderSettings audioSettings; audioSettings.setCodec("audio/mpeg"); audioSettings.setChannelCount(2); recorder->setAudioSettings(audioSettings);
See also QMediaRecorder and QAudioEncoderSettingsControl.
Construct a null audio encoder settings object.
Constructs a copy of the audio encoder settings object other.
Destroys an audio encoder settings object.
Returns the bit rate of the compressed audio stream in bits per second.
See also setBitRate().
Returns the number of audio channels.
See also setChannelCount().
Returns the audio codec.
See also setCodec().
Returns the audio encoding mode.
See also setEncodingMode() and QMultimedia::EncodingMode.
Returns the value of encoding option.
See also setEncodingOption() and encodingOptions().
Returns the all the encoding options as QVariantMap.
See also encodingOption() and setEncodingOptions().
Identifies if an audio settings object is initialized.
Returns true if the settings object is null, and false if it is not.
Returns the audio encoding quality.
See also setQuality().
Returns the audio sample rate in Hz.
See also setSampleRate().
Sets the audio bit rate in bits per second.
See also bitRate().
Sets the number of audio channels.
A value of -1 indicates the encoder should make an optimal choice based on what is available from the audio source and the limitations of the codec.
See also channelCount().
Sets the audio codec.
See also codec().
Sets the audio encoding mode setting.
If QMultimedia::ConstantQualityEncoding is set, the quality encoding parameter is used and bit rate is ignored, otherwise the bitrate is used.
The audio codec, channels count and sample rate settings are used in all the encoding modes.
See also encodingMode() and QMultimedia::EncodingMode.
Set the encoding option to value.
The supported set and meaning of encoding options are system and selected codec specific.
See also encodingOption() and setEncodingOptions().
Replace all the encoding options with options.
The supported set and meaning of encoding options are system and selected codec specific.
See also encodingOptions(), encodingOption(), and setEncodingOption().
Set the audio encoding quality.
Setting the audio quality parameter allows backend to choose the balanced set of encoding parameters to achieve the desired quality level.
The quality settings parameter is only used in the constant quality encoding mode.
See also quality().
Sets the audio sample rate in Hz.
A value of -1 indicates the encoder should make an optimal choice based on what is avaialbe from the audio source and the limitations of the codec.
See also sampleRate().
Determines if other is of equal value to an audio encoder settings object.
Returns true if the settings objects are not of equal value, and true if they are of equal value.
Assigns the value of other to an audio encoder settings object.
Determines if other is of equal value to an audio encoder settings object.
Returns true if the settings objects are of equal value, and false if they are not of equal value.
