The main library for audio -and video playback is \e mmrenderer. For low-latency output of raw audio samples, -\e libasound, a variant of the Linux ALSA library, is available. Finally, for -three-dimensional positional audio playback, \e OpenAL is supported and present -on BB10. - -The Qt Multimedia BlackBerry backend uses mmrenderer for media playback. - -For the positional audio classes in the \l{Qt Audio Engine QML Types}{Qt Audio Engine} -QML module, OpenAL is used as on all other platforms. - -For recording videos and taking photos, the camapi library is used. - -\section1 Supported Features - -Playback of audio and video with QMediaPlayer and related classes is supported. -This includes the corresponding QML elements like MediaPlayer and VideoOutput. -Since the playback is delegated to mmrenderer, the supported formats are the same as in -mmrenderer. As mmrenderer supports streaming from HTTP and other URLs, this is -supported in QMediaPlayer as well. Playlists as sources are also supported. - -mmrenderer does not allow access to the pixel data of video frames, hence Qt Multimedia -classes like QVideoFrame and QAbstractVideoSurface will not work since they require access -to the image data. QVideoWidget and the VideoOutput QML element are implemented with an overlay window; -mmrenderer creates a separate window displaying a video and puts that on top of the Qt application. -As a consequence, no other widget or QML element can be put on top of the video, and QML shaders have -no effect. - -The \l{Qt Audio Engine QML Types}{Qt Audio Engine} QML module is fully supported, as it is based on OpenAL which is available -in BB10. - -The \l {camera} {QCamera} support includes recording of videos and taking photos. The viewfinder -is available through QCameraViewfinder and the VideoOutput QML element. - -Note: To use the camera on BB10, your application needs the 'access_shared', 'use_camera' and 'record_audio' -permissions set in the bar-descriptor.xml file. - -\section1 Unsupported Features - -Low-latency output and input of raw audio samples with QAudioOutput, QAudioInput and related classes is -not yet supported. The SoundEffect QML element and QSoundEffect are based on these classes. In your -QML file, use the MediaPlayer element instead of the SoundEffect element, as the APIs are nearly identical. - -QMediaPlayer does not support QIODevice-based streaming sources. However, streaming by specifying, for example, -an HTTP URL as the source does work. In addition, QMediaPlayer does not yet provide metadata like -the artist and album of the current track. - -Radio and audio recording are not yet supported. -*/ |
