924795c85c vtdec: Negotiate the decoder in set_format() already
Don't wait until later, we want to know here if the codec can be opened or not
for the requested format. This was removed (accidentially?) by
  119e09eac3

Without this decodebin has no way to switch to a different decoder if this one
does not work.

4aaaf23868 applemedia: videotesturecache: let CVOpenGLESTextureCache flush every 1s
Leave kCVOpenGLESTextureCacheMaximumTextureAgeKey to the default (1s). We used
to set it to 0 and flush manually, but apparently (looking at the GLES profiler)
0 means "disable the cache entirely".

936b2fdfbc applemedia: implement GstAppleCoreVideoMemory
Implement a new memory type wrapping CVPixelBuffer.

There are two immediate advantages:
 a) Make the GstMemory itself retain the CVPixelBuffer. Previously,
    the containing GstBuffer was solely responsible for the lifetime of
    the backing CVPixelBuffer.

    With this change, we remove the GST_MEMORY_FLAG_NO_SHARE so that
    GstMemory objects be referenced by multiple GstBuffers (doing away
    with the need to copy.)

  b) Delay locking CVPixelBuffer into CPU memory until it's actually
     mapped -- possibly never.

The CVPixelBuffer object is shared among references, shares and
(in planar formats) planes, so a wrapper GstAppleCoreVideoPixelBuffer
structure was introduced to manage locking.

e0d65937bc applemedia: vtenc: accept UYVY on Mac
When doing GLMemory avfvideosrc negotiates UYVY. This change allows avfvideosrc
! tee name=t ! ... ! glimagesink t. ! ... ! gldownload ! vtenc_h264 ! ...

a15d8acff0 applemedia: avfvideosrc: change texture format from BGRA to NV12 on iOS
Change texture format from BGRA to NV12. This allows a pipeline like avfvideosrc
! tee name=t ! ... ! glimagesink t. ! ... ! gldownload ! vtenc_h264 ! ...  to
negotiate GLMemory. This makes the glimagesink branch much faster (obviously)
and triggers the 0-copy path between avfvideosrc and vtenc (using the CV meta).
Combined this results in a huge perf improvement on iOS (25-30% of CPU time in a
pipeline like the one above).

Note that this doesn't introduce a new shader conversion in the sink, since BGRA
textures had to be copied/converted from format=BGRA,texture-target=RECTANGLE to
format=RGBA,texture-target=2D anyway.

Year 12: I still don't understand how negotiation works.

Apparently gst_pad_query_caps doesn't do what I thought it did. To get the

with the template caps as filter.

0cc6d16c94 applemedia/avsample: Fix racy cleanup of CA layer
The block that is dispatched async to the main thread assumed the
wrapping GstAvSampleVideoSink to be alive. However, at the time of
the block execution the GstObject instance that is deferenced to access
the CA layer might already be freed, which caused occasional crashes.
Instead, we now only pass the CoreAnimation layer that needs to be
released to the block. We use __block to make sure the block is not
increasing the refcount of the CA layer again on its own.

bfa054a733 vtdec: handle non-consecutive GstBuffer input without copying
CMBlockBuffer offers a model similar to GstBuffer, as it can
consist of multiple non-consecutive memory blocks.

Prior to this change, what we were doing was:

 1) Incorrect:

   CMBlockBufferCreateWithMemoryBlock does not copy the data,
   but we gst_buffer_unmap'd right away.

 2) Inefficient:

   If the GstBuffer consisted of non-contiguous memory blocks,
   gst_buffer_map resulted in malloc / memcpy.

With this change, we construct a CMBlockBuffer out of individual mapped
GstMemory objects. CMBlockBuffer is made to retain the GstMemory
objects (through the use of CMBlockBufferCustomBlockSource), so the
original GstBuffer can be unref'd.

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.

4cca6efda8 vtdec: Require width and height field for H264
This decoder does not work if width and height field are not set
in the sinkpad caps. Let's make this explicit by adding them to
the template caps.

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.
