Constructor & Destructor Documentation

PulseAudioDevice()

PulseAudioDevice::PulseAudioDevice	(	std::string	name,
		DeviceSpecs	specs,
		int	buffersize = AUD_DEFAULT_BUFFER_SIZE
	)

Opens the PulseAudio audio device for playback.

Parameters

specs	The wanted audio specification.
buffersize	The size of the internal buffer.

Note

The specification really used for opening the device may differ.

Exceptions

Exception

Thrown if the audio device cannot be opened.

Member Function Documentation

getSynchronizer()

virtual ISynchronizer * PulseAudioDevice::getSynchronizer ( )

virtual

Retrieves the synchronizer for this device, which enables accurate synchronization between audio playback and video playback for example.

Returns

The synchronizer which will be the DefaultSynchronizer if synchonization is not supported.

Reimplemented from SoftwareDevice.

playing()

virtual void PulseAudioDevice::playing ( bool  playing )

protectedvirtual

This function tells the device, to start or pause playback.

Parameters

playing

True if device should playback.

Note

This method is only called when the device is locked.

Implements SoftwareDevice.
