abdb30c567 celvideosrc: fix nasty deadlock 
We cannot call any CMBufferQueue functions while holding the lock that
our callback also depends on. So now we make use of CMBufferQueue's
trigger API in order to get notified when the queue has data.

e4db4257d5 celvideosrc: unlock should also notify 
Otherwise we depend on being woken up by the CoreMedia queue getting
its next buffer.

ebd2a6d6e9 applemedia: don't push synchronously from callback 
The codec that called us might be holding locks to shared resources, so
we should never push downstream from within its buffer callback.

Note that a GstBufferList is not used here because we need to preserve
the buffer metadata held by our GstBuffer subclasses.

b4654f537f applemedia: lock CVPixelBuffer read-only 
As per Apple's docs, this may improve performance by avoiding redundant
invalidations of existing caches of the buffer contents.

c2672f71cd applemedia: improve vtenc/vtdec performance 
Profiling of H.264 encode and decode revealed that conversions
between packed and planar were happening behind the scenes.

Hence we now choose I420 instead of YUY2.

8b22f855ec avfvideosrc: don't explicitly empty the buffer queue

3a44d4c1f9 qtkitvideosrc: fix up refcounting 
Should keep a strong reference to the device, but we don't need to manage
the reference count of elements of an NSMutableArray as it takes care of
that for us.

b39609b405 qtkitvideosrc: simplify timestamping algorithm 
Aligning timestamps on duration boundaries, skipping frames and so forth
are clearly things that fall outside the scope of a video source.

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.

cc1c6ee9e3 winks: work around shutdown deadlock 
GetOverlappedResult() might never return with some drivers. Time out
after 1000 ms. We cannot really fix this without either:
1) Controlling the streaming thread so we can do CancelIo() from that
   thread.
2) Switch to using IO completion ports.

c1d16c4fee winks: retry when KsCreatePin fails with ERROR_NOT_READY 
Turns out that the reference implementation does this, hence we need to
mirror this behaviour. This typically happens with hardware that takes
some time to initialize.

bb17394e76 winks: improve framerate fraction conversions 
* For instance 7.5 fps should be represented as 15/2 instead of 7/1.

d282a1d380 winks: improve error-handling 
Most important part here is special-casing "device busy" so the application
is able to provide better feedback when another application is using the
device.

cddfa50d92 winks: performance improvements 
* Make the driver write directly into each GstBuffer to avoid memcpy().
* Don't memset() the buffer before reusing it.
* Recycle memory by keeping two spare buffers. Two because the sink
  downstream may keep a ref to the previous buffer.

Note that we align buffers on highest possible byte boundary (4096) so we
don't have to take into account what kind of alignment the driver requires.
