QVideoEncoderSettings露

PyQt5.QtMultimedia.QVideoEncoderSettings

Description露

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 setEncodingSettings() function.

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

#     recorder->setVideoSettings(videoSettings);

Methods露

__init__()

Constructs a null video encoder settings object.

__init__(QVideoEncoderSettings)

Constructs a copy of the video encoder settings object other.

bitRate() → int

Returns bit rate of the encoded video stream in bits per second.

See also

setBitRate().

codec() → str

Returns the video codec.

See also

setCodec().

encodingMode() → EncodingMode

Returns the video encoding mode.

See also

setEncodingMode(), EncodingMode.

encodingOption(str) → Any

Returns the value of encoding option.

See also

setEncodingOption(), encodingOptions().

encodingOptions() → Dict[str, Any]

Returns the all the encoding options as QVariantMap.

See also

encodingOption(), setEncodingOptions().

__eq__(QVideoEncoderSettings) → bool

TODO

frameRate() → float

Returns the video frame rate.

See also

setFrameRate().

isNull() → bool

Identifies if a video encoder settings object is uninitalized.

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

__ne__(QVideoEncoderSettings) → bool

TODO

quality() → EncodingQuality

Returns the video encoding quality.

See also

setQuality().

resolution() → QSize

Returns the resolution of the encoded video.

See also

setResolution().

setBitRate(int)

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

See also

bitRate().

setCodec(str)

Sets the video codec.

See also

codec().

setEncodingMode(EncodingMode)

TODO

setEncodingOption(str, Any)

Set the encoding option value.

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

See also

encodingOption(), setEncodingOptions().

setEncodingOptions(Dict[str, Any])

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(), setEncodingOption().

setFrameRate(float)

See also

frameRate().

setQuality(EncodingQuality)

TODO

setResolution(QSize)

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.

See also

resolution().

setResolution(int, int)

Sets the width and height of the resolution of the encoded video.

This is an overloaded function.
