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
