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.

The video toolbox is not available on iOS, and also on OSX
we should probably build all source files that are used for
it.

3ba76f825d applemedia: add new iOS video source based on AVFoundation
This element makes use of the documented AVFoundation framework made
available starting with iOS 4.0, and hence this means we can finally
capture video using a public API.

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.
