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.
timestamps are now chosen in the following order:
upstream -> parsed by decoder -> calculated from timestamp offset
we also check the timestamps supplied from upstream/decoder to see if they
atleast is increasing.
This way we'll reuse the GstVdp[Video|Output]Buffers if they're of the same
size and chroma-type/rgba-format.
Also remove gst_vdp_output_src_pad_negotiate and set a "setcaps" function on
GstVdpOutputSrcPad instead, leaving negotiation to GstVdpVideoPostProcess.
instead we do as GstVdpVideoSrcPad and use the "templ" property of GstPad,
which enable us to change the signature of gst_vdp_output_src_pad_new to match
gst_pad_new_from_template
we now no longer try to get the GstVdpDevice from downstream since it in
practice didn't give us anything and complicates the code alot. Nevertheless if device
distribution should be done there's probably a lot better ways to do it.
Instead we now simply aquire the device in vdpauvideopostprocess when we're
going into PAUSED.

* Inherit from GstVideoSink
* Implement GstNavigation interface
* Proper COM initialization for threaded environments
* Fix Window resource leak
* Add EVR support for better video scaling on Windows Vista and above
* Only apply PAR scaling when the keep_aspect_ratio property is set to stay
consistent with the other Linux sinks
* Prevent an infinite loop with the wndproc chain
* Fix debugging messages to use the object instance
