Windows

Linux & Embedded Linux

OS X & iOS

Multimedia support for apple products are provided by two plugins. The QuickTime 7 plugin is the legacy plugin, providing limited multimedia support to OS X 10.6, and is not actively developed. The AVFoundation plugin is available on OS X 10.7+ as well as iOS. This is the actively developed plugin and should be used where possible.

Android

Android Base-layer

Blackberry 10 (QNX)

QtMultimedia Plugin Interfaces

QtMultimedia's functionality for a given platform is defined using the Qt plugin system through the implementation of interfaces. These interfaces can be seen split several ways, but for our purposes they will be split between the high level and low level API's.

High-level Multimedia Interfaces:

Interface Description
QAudioDecoderControl Access to the audio decoding functionality of a QMediaService
QAudioEncoderSettingsControl Access to the settings of a media service that performs audio encoding
QAudioInputSelectorControl Audio input selector media control
QAudioOutputSelectorControl Audio output selector media control
QCameraCaptureBufferFormatControl Control for setting the capture buffer format
QCameraCaptureDestinationControl Control for setting capture destination
QCameraControl Abstract base class for classes that control still cameras or video cameras
QCameraExposureControl Allows controlling camera exposure parameters
QCameraFeedbackControl Allows controlling feedback (sounds etc) during camera operation
QCameraFlashControl Allows controlling a camera's flash
QCameraFocusControl Supplies control for focusing related camera parameters
QCameraImageCaptureControl Control interface for image capture services
QCameraImageProcessingControl Abstract class for controlling image processing parameters, like white balance, contrast, saturation, sharpening and denoising
QCameraLocksControl Abstract base class for classes that control still cameras or video cameras
QCameraViewfinderSettingsControl Abstract class for controlling camera viewfinder parameters
QCameraZoomControl Supplies control for optical and digital camera zoom
QImageEncoderControl Access to the settings of a media service that performs image encoding
QMediaAudioProbeControl Allows control over probing audio data in media objects
QMediaAvailabilityControl Supplies a control for reporting availability of a service
QMediaContainerControl Access to the output container format of a QMediaService
QMediaGaplessPlaybackControl Access to the gapless playback related control of a QMediaService

QMediaVideoProbeControl Allows control over probing video frames in media objects
QMetaDataReaderControl Read access to the meta-data of a QMediaService's media
QMetaDataWriterControl Write access to the meta-data of a QMediaService's media
QRadioDataControl Access to the RDS functionality of the radio in the QMediaService
QRadioTunerControl Access to the radio tuning functionality of a QMediaService
