* Added support for video surfaces to Phonon MMF backendGareth Stockwell2010-03-1828-1163/+1982
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Symbian^3 introduces a new compositing graphics subsystem in which non-UI content such as video is provided by client applications via graphics surfaces. This patch modifies the video playback part of the Phonon MMF backend so that, on devices which use the new graphics architecture (NGA), video is rendered to a surface. On devices which use the legacy graphics architecture, the existing video rendering path, which uses Direct Screen Access (DSA) is maintained. On NGA devices, video playback applications do not deal with surfaces directly; instead, they use a new MMF client API called CVideoPlayerUtility2. The implementation of this API takes care of creating a graphics surface, registering it with the window manager, and directing the output of the video decoder into this surface. CVideoPlayerUtility2 inherits from the legacy video playback API, CVideoPlayerUtility, deprecating certain functions and adding new ones. The main changes involved in modifying CVideoPlayerUtility client code to instead use CVideoPlayerUtility2 are: 1. CVideoPlayerUtility requires a window handle to be provided at object construction time. The CVideoPlayerUtility2 constructor does not take a window handle; it is provided by the client later via the SetDisplayWindowL function. 2. CVideoPlayerUtility requires the client to provide an absolute screen rectangle at construction time, and then to call SetDisplayWindowL whenever this rectangle changes due to either window repositioning or resizing. CVideoPlayerUtility2 requires the client to provide a display rectangle which is relative to the display window. This rectangle must be updated via SetVideoExtentL / SetWindowClipRectL when the window is resized, but no update is required when the window is repositioned - the compositing window system takes care of repositioning the video content on the screen. 3. CVideoPlayerUtility requires the client to paint transparent black into the region of the window in which video will be displayed. CVideoPlayerUtility2 does not require the client to paint the video window. In order to accomodate these differences, the existing VideoPlayer and VideoOutput classes are replaced with AbstractVideoPlayer and AbstractVideoOutput respectively. These abstract base classes encapsulate functionality which is common between the DSA and surface rendering client code. Because CVideoPlayerUtility2 inherits from CVideoPlayerUtility, AbstractVideoPlayer is able to hold a pointer to CVideoPlayerUtility, via which it controls functionality which is not affected by the details of the rendering path, such as play/pause/stop, seek and metadata access. The three areas of divergence listed above are encapsulated in the derived classes DsaVideoOutput/SurfaceVideoOutput and DsaVideoPlayer/ SurfaceVideoPlayer. Of the three, (1) and (3) are fairly straightforward. For DSA video playback, the need to respond to changes in video widget absolute screen position in (2) necessitated the AncestorMoveMonitor class, which installs an event filter on each ancestor of the video widget. This class is not required for surface video playback and is therefore removed from the surface-rendering code path. Selection of either the DSA- or surface-rendering code path is done at qmake time, via the exists(...) check introduced in mmf.pro. This checks for existence of the header in which CVideoPlayerUtility2 is defined; if this file is found, surface rendering is selected, otherwise the DSA rendering version of the backend is built. Note that this approach is not completely robust, since it is possible for an environment to include the videoplayer2.h header and yet be configured to use the legacy graphics subsystem. This could be dealt with by instead performing the check for surface support at configuration time, building and executing a small Symbian program which will return different output according to which of the two graphics subsystems is in use.

This is now done inside the backend class for each effect, thereby improving encapsulation. Task-number: QTBUG-4659 Reviewed-by: Espen Riskedal
* Delayed creation of audio effect object until audio is initializedGareth Stockwell2010-01-118-23/+63
| | | | | | | | | | | | | | | | | | When applying effects to an audio stream, we must ensure that the MMF utility API (CMdaAudioPlayerUtility or CVideoPlayerUtility) instance has loaded a controller before calling attempting to create a CAudioEffect- derived object. If the controller has not been loaded, construction of the effect object will fail. Even if we mitigate against this, calling CAudioEffect::ApplyL() will only have an effect if there is a controller object - or more precisely, a DevSound instance - on which to apply the effect. This patch delays construction of the effect object until the MediaObject has transitioned out of the LoadingState, indicating that an underlying DevSound instance will have been created.

* Modified effect parameter handling to improve user experienceGareth Stockwell2010-01-118-23/+173
| | | | | | | | | | | | | | | | | | This change is to work around a limitation in the Phonon::EffectWidget class. This widget only displays sliders for parameters with numeric values if the variant type of the parameter is QReal and the range is exactly -1.0 to +1.0; otherwise, a spinbox is displayed. This is rather inconvenient for many effects, such as the audio equalizer, for which a slider is a much more natural UI control. The MMF backend therefore reports the type of numeric parameters to be QReal, and the range to be -1.0 to +1.0. Internally, the integer range for the parameter is stored. Changes to the parameter value are converted from the client-side, floating point representation to the internal, integer representation. Task-number: QTBUG-4659 Reviewed-by: Espen Riskedal

* Implemented audio effects capability querying in Phonon MMF backendGareth Stockwell2010-01-0810-132/+225
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch addresses the following deficiencies in the existing implementation of audio effects: 1. Native effect objects (e.g. CAudioEqualizer, CBassBoost etc) were created frequently, just in order to check whether a given effect is supported, or retrieve the list of parameters which it requires. Although this is in part due to a deficiency in the S60 audio effects API (it doesn't have a 'capability query' concept), it can be improved by using caching. This patch introduces a singleton EffectFactory object, which lazily initializes a data structure containing information about support and parameters. 2. In order to either query effect support, the native effect object ultimately needs to access a DevSound instance. Previously, the effect object was provided with a CMdaAudioPlayerUtility object. If this player utility has not loaded an MMF controller plugin *before* the effects object makes any calls to the player utility, incorrect results will be returned. This was observed in the previous code. For querying, we don't actually need to load an MMF controller; instead, we would like to directly provide a CMMFDevSound instance to the effect object. Unfortunately, this API is not available in public S60 SDKs, so we must use the next lowest interface available, namely CMdaAudioOutputStream. By making this change, this patch ensures that support and parameter queries made via the EffectFactory will return the correct result. At this point, however, effect settings made via the Phonon API are not actually applied to the audio output. Fixing this will require notifying the audio effects backend nodes of state changes in the MediaObject. Task-number: QTBUG-4659 Reviewed-by: Espen Riskedal

| | | | | | | | | | | | Modified the sequence of calls made to the MMF APIs when seeking during ongoing playback. This fixes a bug found during early testing of streaming playback, whereby playback would not resume following the seeking operation. This was due to an interaction between the pause / seek / play operations, and the buffering callbacks received from the MMF, which caused the backend to enter an incorrect state.

| | | | | | | | | | | | When clips are buffering (either at the start of playback, or during playback, when buffer levels drop due to e.g. CPU, file system or network load), the backend receives notification from the MMF.

* Added support for streaming playback to Phonon MMF backendGareth Stockwell2009-12-088-6/+30
| | | | | | | | | | | | | | | | Because the MIME type of the stream cannot always be deduced from the URL, we assume that it is a video stream. This is based on the assumption that the video controllers will be capable of parsing the container formats for audio-only, as well as video clips. Note that this assumption may not hold on all devices. Note that most implementations of the MMF client APIs do not support HTTP streaming (a.k.a. progressive download). The backend has therefore only been tested with RTSP streams - see the JIRA entry for further details. Task-number: QTBUG-4660 Reviewed-by: Frans Englich
