367b4a353f qtkit: drop the qtkitvideosrc element
The QTKit framework had been deprecated for long in favour of AVFundation
framework and we already have avfvideosrc that provides the same
functionality.

46bbc60d24 applemedia/gl: Update code to use ARC
All code interacting with Objective-C objects should now use Automated
Reference Counting rather than manual memory management or Garbage
Collection. Because ARC prohibits C-structs from containing
references to Objective-C objects, all such fields are now typed
'gpointer'. Setting and gettings Objective-C fields on such a
struct now uses explicit __bridge_* calls to tell ARC about
object lifetimes.

7898bc5810 applemedia: changes to make GL memory mappable on CPU on iOS
This commit introduces IOSGLMemory which is a GLMemory that falls back to
GstAppleCoreVideoMemory for CPU access. This is a temporary solution until
IOSurface gets exposed as a public framework on iOS and so we can use
IOSurfaceMemory on both MacOS and iOS.

936b2fdfbc applemedia: implement GstAppleCoreVideoMemory
Implement a new memory type wrapping CVPixelBuffer.

There are two immediate advantages:
 a) Make the GstMemory itself retain the CVPixelBuffer. Previously,
    the containing GstBuffer was solely responsible for the lifetime of
    the backing CVPixelBuffer.

    With this change, we remove the GST_MEMORY_FLAG_NO_SHARE so that
    GstMemory objects be referenced by multiple GstBuffers (doing away
    with the need to copy.)

  b) Delay locking CVPixelBuffer into CPU memory until it's actually
     mapped -- possibly never.

The CVPixelBuffer object is shared among references, shares and
(in planar formats) planes, so a wrapper GstAppleCoreVideoPixelBuffer
structure was introduced to manage locking.

160df421ea vtdec: Register a hardware-only vtdec_hw on OSX and give it a higher rank
while having the default vtdec at secondary rank. This allows decodebin/playbin
to prefer the hardware based decoders, and if that fails to initialize because
hardware resources are busy to fall back to e.g. the libav based h264 decoder
instead of the software based vtdec (which is slower), and only fall back to
the software based vtdec if there is no higher ranked decoder available.

0e4e351b83 applemedia: New plugin for Apple multimedia APIs
Provides the following elements:

qtkitvideosrc: OS X video source relying on the QTKit API. Comes with
hard-coded caps as the API does not provide any way of querying for
formats supported by the hardware. Hasn't been tested a lot, but seems
to work.

miovideosrc: OS X video source which uses the undocumented/private
CoreMediaIOServices API, which is also the one used by iChat.
Present on latest version of Leopard and all versions of Snow Leopard.
Has been tested extensively with built-in cameras and TANDBERG's
PrecisionHD USB camera.

vtenc, vtdec: Generic codec wrappers which make use of the undocumented/
private VideoToolbox API on OS X and iOS. List of codecs are currently
hard-coded to H.264 for vtenc, and H.264 + JPEG for vtdec. Can easily be
expanded by adding new entries to the lists, but haven't yet had time to
do that. Should probably also implement probing as available codecs depend
on the OS and its version, and there doesn't seem to be any way to
enumerate the available codecs.

vth264decbin, vth264encbin: Wrapper bins to make it easier to use
vtdec_h264/vtenc_h264 in live scenarios.

iphonecamerasrc: iPhone camera source relying on the undocumented/private
Celestial API. Tested on iOS 3.1 running on an iPhone 3GS. Stops working
after a few minutes, presumably because of a resource leak. Needs some
love.

Note that the iOS parts haven't yet been ported to iOS 4.x.
