94e7ed1323 vtenc: fix keyframe request race condition 
It is incorrect to modify the frame properties after passing them, since
VTCompressionSessionEncodeFrame takes reference and we have no control
over when it's being used.

In fact, the code can be simplified. We just preallocate the frame
properties for keyframe requests, and pass NULL otherwise.

c948484c7f avfvideosrc: fix unconditional buffer queue unlock 
Unless stopRequest is set, we should unlock conditionally -- otherwise,
the 'create:' method can wake up to an empty buffer queue
and pull a nil buffer.

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.

0593480381 applemedia/avsamplesink: utilise a pull based approach of displaying video frames 
Using requestMediaDataWhenReadyOnQueue the layer will execute a block
when it would like more frames. Using this we can provide the current
frame and avoid needlessly filling the layer's buffer queue causing
older frames to be displayed when under resource pressure.

Otherwise we might set bogus values or GST_CLOCK_TIME_NONE.

Also make sure to reset the caps field to NULL after unreffing
the caps to prevent accidential use afterwards, and unref any
old caps before we remember new caps.
