The QVideoEncoderSettings class provides a set of video encoder settings.
A video encoder settings object is used to specify the video encoder settings used by QMediaRecorder. Video encoder settings are selected by constructing a QVideoEncoderSettings object, setting the desired properties and then passing it to a QMediaRecorder instance using the QMediaRecorder::setEncodingSettings() function.
QVideoEncoderSettings videoSettings; videoSettings.setCodec("video/mpeg2"); videoSettings.setResolution(640, 480); recorder->setEncodingSettings(audioSettings, videoSettings);

Constructs a null video encoder settings object.
Constructs a copy of the video encoder settings object other.

Destroys a video encoder settings object.
Returns bit rate of the encoded video stream in bits per second.
This function was introduced in Qt Mobility 1.0.
See also setBitRate().
Returns the video codec.
This function was introduced in Qt Mobility 1.0.
See also setCodec().
Returns the video encoding mode.
This function was introduced in Qt Mobility 1.0.
See also setEncodingMode() and QtMultimediaKit::EncodingMode.
Returns the video frame rate.
This function was introduced in Qt Mobility 1.0.
See also setFrameRate().
Identifies if a video encoder settings object is uninitalized.
Returns true if the settings are null, and false if they are not.
This function was introduced in Qt Mobility 1.0.
Returns the video encoding quality.
This function was introduced in Qt Mobility 1.0.
See also setQuality().
Returns the resolution of the encoded video.
This function was introduced in Qt Mobility 1.0.
See also setResolution().
Sets the bit rate of the encoded video stream to value.
This function was introduced in Qt Mobility 1.0.
See also bitRate().
Sets the video codec.
This function was introduced in Qt Mobility 1.0.
See also codec().
Sets the video encoding mode.
If QtMultimediaKit::ConstantQualityEncoding is set, the quality encoding parameter is used and bit rate is ignored, otherwise the bitrate is used.
The rest of encoding settings are respected regardless of encoding mode.
This function was introduced in Qt Mobility 1.0.
See also encodingMode() and QtMultimediaKit::EncodingMode.
Sets the video frame rate.
A value of 0 indicates the encoder should make an optimal choice based on what is available from the video source and the limitations of the codec.
This function was introduced in Qt Mobility 1.0.
See also frameRate().
Sets the video encoding quality.
Setting the video 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. The quality settings parameter is only used in the constant quality encoding mode.
This function was introduced in Qt Mobility 1.0.
See also quality().
Sets the resolution of the encoded video.
An empty QSize indicates the encoder should make an optimal choice based on what is available from the video source and the limitations of the codec.
This function was introduced in Qt Mobility 1.0.
See also resolution().
Sets the width and height of the resolution of the encoded video.
This is an overloaded function.
This function was introduced in Qt Mobility 1.0.
Determines if other is of equal value to a video encoder settings object.
Returns true if the settings objects are not of equal value, and false if they are of equal value.
This function was introduced in Qt Mobility 1.0.
Assigns the value of other to a video encoder settings object.
This function was introduced in Qt Mobility 1.0.
Determines if other is of equal value to a video encoder settings object.
Returns true if the settings objects are of equal value, and false if they are not of equal value.
