The QMediaServiceProviderHint class describes what is required of a QMediaService.
The QMediaServiceProvider class uses hints to select an appropriate media service.
Enumerates features a media service may provide.
| Constant | Value | Description |
|---|---|---|
| QMediaServiceProviderHint::LowLatencyPlayback | 0x01 | The service is expected to play simple audio formats, but playback should start without significant delay. Such playback service can be used for beeps, ringtones, etc. |
| QMediaServiceProviderHint::RecordingSupport | 0x02 | The service provides audio or video recording functions. |
| QMediaServiceProviderHint::StreamPlayback | 0x04 | The service is capable of playing QIODevice based streams. |
| QMediaServiceProviderHint::VideoSurface | 0x08 | The service is capable of renderering to a QAbstractVideoSurface output. |
The Features type is a typedef for QFlags<Feature>. It stores an OR combination of Feature values.
Enumerates the possible types of media service provider hint.
| Constant | Value | Description |
|---|---|---|
| QMediaServiceProviderHint::Null | 0 | En empty hint, use the default service. |
| QMediaServiceProviderHint::ContentType | 1 | Select media service most suitable for certain content type. |
| QMediaServiceProviderHint::Device | 2 | Select media service which supports certain device. |
| QMediaServiceProviderHint::SupportedFeatures | 3 | Select media service supporting the set of optional features. |
