Type Documentation

typedef Phonon::AudioOutputDevice

This typedef of ObjectDescription describes an audio output device, such as soundcards (with different drivers), sound servers, or other virtual outputs like playback on a different computer on the network.

A list of available devices is given by the backend with Backendcapabilities::availableAudioOutputDevices()

     QList<Phonon::AudioOutputDevice> audioOutputDevices =
             Phonon::BackendCapabilities::availableAudioOutputDevices();

typedef Phonon::AudioOutputDeviceModel

provides an item view model containing available audio output devices.

enum Phonon::Category

Sets the category your program should be listed in in the mixer.

A Jukebox will set this to Music, a VoIP program to Communication, a DVD player to video, and so on.

Note: These categories can also become useful for an application that controls the volumes automatically, like turning down the music when a call comes in, or turning down the notifications when the media player knows it's playing classical music.

enum Phonon::DiscType

Enum to identify the media discs supported by MediaObject.

See also MediaSource and MediaObject.

typedef Phonon::EffectDescription

EffectDescription gives a description of an audio effect. It is a typedef of the ObjectDescription class. Please see its class description for details.

EffectDescription is used to create audio Effects, which can be inserted into a media graph, altering an audio stream.

See also Phonon::ObjectDescription, Capabilities Example, and Media Player.

typedef Phonon::EffectDescriptionModel

provides a item view model containing available audio effects.

enum Phonon::ErrorType

This enum describes the severity when an error has occurred during playback.

After a media object has entered the ErrorState, one can query the type of error from MediaObject::errorType(). Note that you should query the error when receiving the MediaObject::stateChanged() signal, because the error type will be lost if the media object leaves the error state.

See also MediaObject::errorType().

enum Phonon::MetaData

Provided as keys for Phonon::MediaObject::metaData(). The enum values matches strings defined in the Ogg Vorbis specification

enum Phonon::ObjectDescriptionType

This enum defines the type of information that is contained in a ObjectDescription object.

enum Phonon::State

The state enum describes the different states a media object can take. Several functions of MediaObject are asynchronous, so even if a you have requested a state change through a function call, e.g., through play(), you cannot be sure that the change has taken place before you receive the stateChanged() signal.

A media object can at any time change into any state, regardless of the state it previously had.

This enum was introduced or modified in Qt 4.4.

See also MediaObject.

typedef Phonon::VideoWidgetInterfaceLatest

This typedef was introduced in Qt 4.7.
