Synopsis

Functions

Detailed Description

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 setEncodingSettings() function.

QVideoEncoderSettings videoSettings;
videoSettings.setCodec("video/mpeg2");
videoSettings.setResolution(640, 480);

recorder->setVideoSettings(videoSettings);
class QVideoEncoderSettings

QVideoEncoderSettings(other)

param other

QVideoEncoderSettings

Constructs a null video encoder settings object.

Constructs a copy of the video encoder settings object other .

setFrameRate()

PySide2.QtMultimedia.QVideoEncoderSettings.isNull()
Return type

bool

Identifies if a video encoder settings object is uninitalized.

Returns true if the settings are null, and false if they are not.

PySide2.QtMultimedia.QVideoEncoderSettings.__ne__(other)
Parameters

otherQVideoEncoderSettings

Return type

bool

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.

PySide2.QtMultimedia.QVideoEncoderSettings.__eq__(other)
Parameters

otherQVideoEncoderSettings

Return type

bool

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.

PySide2.QtMultimedia.QVideoEncoderSettings.quality()
Return type

EncodingQuality

Returns the video encoding quality.

See also

setQuality()

PySide2.QtMultimedia.QVideoEncoderSettings.resolution()
Return type

QSize

Returns the resolution of the encoded video.

setResolution()

PySide2.QtMultimedia.QVideoEncoderSettings.setBitRate(bitrate)
Parameters

bitrateint

Sets the bit rate of the encoded video stream to value .

See also

bitRate()

PySide2.QtMultimedia.QVideoEncoderSettings.setCodec(arg__1)
Parameters

arg__1 – unicode

Sets the video codec .

See also

codec()

PySide2.QtMultimedia.QVideoEncoderSettings.setEncodingMode(arg__1)
Parameters

arg__1EncodingMode

Sets the video encoding mode .

If 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.

PySide2.QtMultimedia.QVideoEncoderSettings.setEncodingOption(option, value)
Parameters
  • option – unicode

  • value – object

Set the encoding option value .

The supported set and meaning of encoding options are system and selected codec specific.

PySide2.QtMultimedia.QVideoEncoderSettings.setEncodingOptions(options)
Parameters

options

Replace all the encoding options with options .

The supported set and meaning of encoding options are system and selected codec specific.

PySide2.QtMultimedia.QVideoEncoderSettings.setFrameRate(rate)
Parameters

rateqreal

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.

PySide2.QtMultimedia.QVideoEncoderSettings.setQuality(quality)
Parameters

qualityEncodingQuality

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 .
