\subsection phonon_Backend_supportsFourcc bool supportsFourcc( quint32 fourcc )
Tells whether the FOURCC (four character code) is supported for
the \ref phonon_VideoDataOutput "VideoDataOutput" interface. If you return \c true, you have to be
able to return VideoFrame objects accordingly from
\ref phonon_VideoDataOutput "VideoDataOutput".
\param fourcc A four character code defining a video frame format.
\returns \c true if your \ref phonon_VideoDataOutput "VideoDataOutput" can
output video frames in the requested format.
\returns \c false if the video frames can not be converted into the requested
format.
\subsection phonon_Backend_availableMimeTypes QStringList availableMimeTypes()
Lists the MIME types the backend can read and decode.
\subsection phonon_Backend_xIndexes QSet<int> <device/codec/effect/...>Indexes()
Returns a set of indexes that identify the devices/codecs/effects/... the
backend supports. This list needs to be compiled from looking at
available hardware and virtual devices/plugins/... . The implementation
should use cached information, but you need to invalidate the cache
whenever the hardware configuration changes or new virtual devices come
available/new plugins are installed/... .
\return The indexes of the available devices/codecs/effects/...
\see \ref phonon_Backend_xName
\see \ref phonon_Backend_xDescription
\subsection phonon_Backend_xName QString <device/codec/effect/...>Name( int index )
Returns the name of the given device/codec/effect/...
\param index The index of one device/codec/effect/... this is one index
out of \ref phonon_Backend_xIndexes
\returns A translated user visible string to name the device.
\see \ref phonon_Backend_xIndexes
\see \ref phonon_Backend_xDescription
\subsection phonon_Backend_xDescription QString <device/codec/effect/...>Description( int index )
Returns the description of the given device/codec/effect/...
\param index The index of one device/codec/effect/... this is one index
out of \ref phonon_Backend_xIndexes
\returns A translated user visible string to describe the device.
\see \ref phonon_Backend_xIndexes
\see \ref phonon_Backend_xName
\subsection phonon_Backend_audioCaptureDeviceVideoIndex qint32 audioCaptureDeviceVideoIndex( int index )
\param index The index of the device. This is one of the indexes the backend
returned via \ref phonon_Backend_xIndexes
\returns An index of a video capture device that is associated with the given
audio capture device. For example a webcam might have both a video and an audio
capture device, and in order give the user a hint that the audio and video
capture devices belong together this index is used.
\returns If there is no associated video capture device return -1.
\subsection phonon_Backend_videoCaptureDeviceAudioIndex qint32 videoCaptureDeviceAudioIndex( int index )
\param index The index of the device. This is one of the indexes the backend
returned via \ref phonon_Backend_xIndexes
\returns An index of a audio capture device that is associated with the given
video capture device. For example a webcam might have both a audio and an video
capture device, and in order give the user a hint that the video and audio
capture devices belong together this index is used.
\returns If there is no associated audio capture device return -1.
