* platform/graphics/MediaPlayer.cpp:
(WebCore::installedMediaEngines):
* platform/graphics/MediaPlayer.h:

Add the new files to the project:
* WebCore.xcodeproj/project.pbxproj:

Drive by fix for ports who implement seekDouble():
* platform/graphics/MediaPlayerPrivate.h:
(WebCore::MediaPlayerPrivateInterface::seekWithTolerance):

Add new Video and AudioTrackPrivate types which handle their own enable state:
* platform/graphics/avfoundation/objc/AudioTrackPrivateMediaSourceAVFObjC.cpp: Added
