Field Summary

static javax.media.CaptureDeviceInfo	defaultCaptureDevice The default capture device.
static javax.media.CaptureDeviceInfo	defaultPlaybackDevice The default playback device.
static String	LOCATOR_PROTOCOL The protocol of the MediaLocators identifying PortAudio CaptureDevices
static javax.media.CaptureDeviceInfo[]	playbackDevices An array of the devices that can be used for playback.

Constructor Summary

PortAudioAuto()
Initializes a new PortAudioAuto instance which creates PortAudio capture devices by enumerating all host devices with input channels.

Method Summary

void	deviceChanged() PortAudio device changed callback.
static double	getSupportedSampleRate(boolean input, int deviceIndex, int channelCount, long sampleFormat) Gets a sample rate supported by a PortAudio device with a specific device index with which it is to be registered with JMF.
static boolean	isSupported() Determines whether PortAudio is supported.
void	reinit() Reinitializes PortAudio system.

Constructor Detail

PortAudioAuto

PortAudioAuto()
        throws Exception

Initializes a new PortAudioAuto instance which creates PortAudio capture devices by enumerating all host devices with input channels.

Throws:

Exception - if anything wrong happens while creating the PortAudio capture devices

Method Detail

deviceChanged

public void deviceChanged()

PortAudio device changed callback.

reinit

public void reinit()
            throws Exception

Reinitializes PortAudio system.

Throws:

Exception - if anything wrong happens while creating the PortAudio capture devices

getSupportedSampleRate

public static double getSupportedSampleRate(boolean input,
                                            int deviceIndex,
                                            int channelCount,
                                            long sampleFormat)

Gets a sample rate supported by a PortAudio device with a specific device index with which it is to be registered with JMF.

Parameters:

input - true if the supported sample rate is to be retrieved for the PortAudio device with the specified device index as an input device or false for an output device

deviceIndex - the device index of the PortAudio device for which a supported sample rate is to be retrieved

channelCount - number of channel

sampleFormat - sample format

Returns:

a sample rate supported by the PortAudio device with the specified device index with which it is to be registered with JMF

isSupported

public static boolean isSupported()

Determines whether PortAudio is supported.

Returns:

true if PortAudio is supported; otherwise, false
