733a780e9d applemedia: vtdec: set reorder queue length to the max DPB length 
Set reorder_queue_frame_delay from the DPB size (in frames). Still not optimal,
as the DPB size is larger than the max bframe forward prediction length, but I
don't know how to compute the latter without parsing every group of pictures.

a2b90eeb8c avfvideosrc: fix build with older SDK not supporting AVDeviceFormat 
AVDeviceFormat and AVFrameRateRange are available in iOS since 7.0
so we need a more dynamic approach to support compilation with older
SDK's. We use a NSObject to avoid referencing those types and key-value
coding or preformSelector to access properties.

Public frameworks don't need to build the API dynamically, we instead

The exception is for VideoToolbox which went public in the 10.8 SDK,
but it's still private in older version of the SDK and iOS. This allow
building the plugin against SDK's where it's not a public framework.

8b22f855ec avfvideosrc: don't explicitly empty the buffer queue 
We're holding the only reference to it so there's no need to explicitly
empty it right before letting go of our reference.

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.

2e349576eb applemedia: support public version of CoreMedia 
Also rename the relevant API so we mirror the public API more closely, and
switch to CoreFoundation CFTypeRef style typedefs. We still support the old
private CoreMedia in order to not break OS X support.

This means that vtenc and vtdec are now compatible with iOS 4.x, and in
theory also future versions of OS X, where this API may turn public like
it has on iOS.

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.
