Detailed Description#

This class represents an output channel that can be used together with QMediaPlayer or QMediaCaptureSession . It enables the selection of the physical output device to be used, muting the channel, and changing the channel’s volume.

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property deviceᅟ: QAudioDevice#

This property holds The audio device connected to this output..

The device property represents the audio device this output is connected to. This property can be used to select an output device from the audioOutputs() list. You can select the system default audio output by setting this property to a default constructed QAudioDevice object.

Access functions:

device()
setDevice()
Signal deviceChanged()

property mutedᅟ: bool#

This property holds The muted state of the current media..

The value will be true if the output is muted; otherwise false.

Access functions:

isMuted()
setMuted()
Signal mutedChanged()

property volumeᅟ: float#

This property holds The current volume..

The volume is scaled linearly, ranging from 0 (silence) to 1 (full volume).

Note

values outside this range will be clamped.

By default the volume is 1.

UI volume controls should usually be scaled non-linearly. For example, using a logarithmic scale will produce linear changes in perceived loudness, which is what a user would normally expect from a volume control.
