It was the backend's responsibility to handle resource files in an appropriate way. In practice, it was either not handled at all, or implemented in an almost identical manner in every backend that does handle it. This is now dealt with in QMediaPlayer, always passing to the backend something it will be able to play. If the backend has the StreamPlayback capability, we pass a QFile from which it streams the data. If it doesn't, we copy the resource to a temporary file and pass its path to the backend.
