I don't think it would be very hard to use the extension function for this
purpose. Can you think of any functionality needed beyond the following?
MouseClickEvent -- int x, int y, int button
KeyEvent -- int keyNum
AudioStreamNames -- QStringList* streamNames
SetAudioStream -- QString* streamName
TextStreamNames -- QStringList* streamNames
SetTextStream -- QString* streamName
AngleCount -- void
SetAngle -- int angle
SetZoom -- int zoom
All these can be added as extensions. The interface for using extensions is
rather clean (i.e. only slightly worse than normal methods), in my humble
streamNames = media->audioStreamNames();
Because of this I think extensions should be used for all features that are
very format-specific. Any video related function not in an extension should
be implemented by all decoders (except they might be write or read only).
Also: nothing prevents a backend plugin from implementing the whole pipeline.
