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

older frames to be displayed when under resource pressure.

The object lock only protects the session, as we modify

And we need to release the video decoder stream lock before
enqueueing a frames. It might wait for our callback to dequeue
a frame from another thread, which will then take the stream
lock too and deadlock.
