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

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

Doc:QMediaStreamsControl Media stream selection control
Doc:QMediaVideoProbeControl Allows control over probing video frames in media objects
Doc:QMetaDataReaderControl Read access to the meta-data of a QMediaService's media
Doc:QMetaDataWriterControl Write access to the meta-data of a QMediaService's media
Doc:QRadioDataControl Access to the RDS functionality of the radio in the QMediaService
Doc:QRadioTunerControl Access to the radio tuning functionality of a QMediaService
Doc:QVideoDeviceSelectorControl Video device selector media control
Doc:QVideoEncoderSettingsControl Access to the settings of a media service that performs video encoding
Doc:QVideoRendererControl Media control for rendering video to a QAbstractVideoSurface
Doc:QVideoWindowControl Media control for rendering video to a window
Doc:QMediaControl Base interface for media service controls
Doc:QMediaService Common base class for media service implementations
