ad8bf99f04 applemedia: enable sharing of CMBlockBuffer data 
Instead of wrapping with GST_MEMORY_FLAG_NO_SHARE, we make the GstMemory
object retain the underlying CMBlockBuffer.

8cd65c3250 applemedia: CMBlockBuffer can be non-contiguous 
CMBlockBufferGetDataLength would return the entire data length, while
size of individual blocks can be smaller. Iterate over the block buffer
and add the individual (possibly non-contiguous) memory blocks.

58ce6d50a0 avfvideosrc: add frame rate range to caps 
When AVFoundation indicates a supported frame rate range, add it to
the caps. This is important for devices such as the iPhone 6, which
indicate a single AVFrameRateRange of 2fps - 60fps.

29c79d7595 vtenc: always enqueue frames, even on error 
Even when we fail to encode frame, we should still enqueue it so
it could be passed into handle_frame (with output_buffer == NULL).
Otherwise, we risk GstVideoEncoder's queue of frames growing unbounded.

Note: We're slightly changing the renegotiation code to accommodate for
frames without output buffers, but this commit takes no ownership over
the way negotiation is being done.

6101fc57b8 vtenc: free input buffer ASAP 
VTCompressionSessionEncodeFrame retains the CVPixelBuffer during
encoding, and will release it as soon as it can (e.g. before it even
calls our callback). This means we can safely release input buffer
at this point, possibly allowing the system to reuse it sooner.

1f7681dd0a vtdec: don't copy meta from input to output 
Copying arbitrary metas is going to cause problems and this should really be
handled by the base class. It overrides most other things already anyway,
including timestamp and duration. Those are just set here now so we can
insert the frame sorted into the queue.

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.

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.

b323fba934 vtenc: Avoid leaking caps object and its copy 
gst_pad_get_pad_template_caps() returns a reference which is unreferenced,
so creating a copy using gst_caps_copy() results in a reference leak. Also
the caps are pushed as an event downstream, but this doesn't consume the
caps so it must still be unreferenced.
