PySide.QtMultimedia.QAbstractAudioOutput class provides access for PySide.QtMultimedia.QAudioOutput to access the audio device provided by the plugin.
PySide.QtMultimedia.QAbstractAudioOutput implements audio functionality for PySide.QtMultimedia.QAudioOutput , i.e., PySide.QtMultimedia.QAudioOutput routes function calls to PySide.QtMultimedia.QAbstractAudioOutput . For a description of the functionality that is implemented, see the PySide.QtMultimedia.QAudioOutput class and function descriptions.
| 返回类型： | PySide.QtCore.int |
|---|
Returns the audio buffer size in bytes.
| 返回类型： | PySide.QtCore.int |
|---|
Returns the free space available in bytes in the audio buffer.
| 返回类型： | PySide.QtCore.qint64 |
|---|
Returns the milliseconds since PySide.QtMultimedia.QAbstractAudioOutput.start() was called, including time in Idle and suspend states.
| 返回类型： | PySide.QtMultimedia.QAudio.Error |
|---|
Returns the error state.
| 返回类型： | PySide.QtMultimedia.QAudioFormat |
|---|
返回 PySide.QtMultimedia.QAudioFormat 被使用。
| 返回类型： | PySide.QtCore.int |
|---|
Returns the notify interval in milliseconds.
| 返回类型： | PySide.QtCore.int |
|---|
Returns the period size in bytes.
| 返回类型： | PySide.QtCore.qint64 |
|---|
Returns the amount of audio data processed since PySide.QtMultimedia.QAbstractAudioOutput.start() was called in milliseconds.
Drops all audio data in the buffers, resets buffers to zero.
Resumes processing audio data after a PySide.QtMultimedia.QAbstractAudioOutput.suspend()
| 参数： | value – PySide.QtCore.int |
|---|
Sets the audio buffer size to value in bytes.
| 参数： | milliSeconds – PySide.QtCore.int |
|---|
Sets the interval for PySide.QtMultimedia.QAbstractAudioOutput.notify() signal to be emitted. This is based on the ms of audio data processed not on actual real-time. The resolution of the timer is platform specific.
| 参数： | device – PySide.QtCore.QIODevice |
|---|---|
| 返回类型： | PySide.QtCore.QIODevice |
Uses the device 作为 PySide.QtCore.QIODevice to transfer data. If device is null then the class creates an internal PySide.QtCore.QIODevice . Returns a pointer to the PySide.QtCore.QIODevice being used to handle the data transfer. This PySide.QtCore.QIODevice can be used to write() audio data directly. Passing a PySide.QtCore.QIODevice allows the data to be transferred without any extra code.
| 返回类型： | PySide.QtMultimedia.QAudio.State |
|---|
Returns the state of audio processing.
| 参数： | arg__1 – PySide.QtMultimedia.QAudio.State |
|---|
Stops the audio output.
Stops processing audio data, preserving buffered audio data.
