詳細描述

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

注意： On WebAssembly platform, due to it's asynchronous nature, QMediaDevices::audioInputsChanged () signal is emitted when the list of audio inputs is ready. User permissions are required. Works only on secure https contexts.

特性文檔編製

device : QAudioDevice

This property holds the audio device connected to this input.

The device property represents the audio device connected to this input. This property can be used to select an input device from the QMediaDevices::audioInputs () list.

You can select the system default audio input by setting this property to a default constructed QAudioDevice 對象。
