According to following two specs, add support for AC4 in tsdemux.

353013fcaa h265parser: Store NumDeltaPocs of reference for hardware accelerators
That's the value of NumDeltaPocs[RefRpsIdx] and we might be able to derive
the value from given sps and slice header.
Because well known hardware implementations refer to the value, however,
storing the value makes things easier.

Following is the list of hardware implementations
* DXVA2: ucNumDeltaPocsOfRefRpsIdx
* NVDEC/VDPAU: NumDeltaPocsOfRefRpsIdx

ba3430a059 h265decoder: Fix for output and removal picture from DPB
See C.5.2.2 Output and removal of pictures from the DPB.

If the number of pictures in the DPB is greater than or equal to
sps_max_dec_pic_buffering_minus1[HighestTid] + 1, then the picture
should be outputted.

00d04784d3 Move CODEC base classes into it's own library
This introduce a library which contains a set of base classes which
handles the parsing and the state tracking for the purpose of decoding
different CODECs. Currently H264, H265 and VP9 are supported. These
bases classes are used to decode with low level decoding API like DXVA,
NVDEC, VDPAU, VAAPI and V4L2 State Less decoders. The new library is
named gstreamer-codecs-1.0 / libgstcodecs.

e12e67099b build: Fix build on systems with wayland-client headers in non-default location
Add a missing dependency to wl_client_dep for the wayland build. Some distros
have the wayland-client headers not installed in /usr/include (which is perfectly
valid, the pkg-config .pc file gives the right feedback).

8e3472faee webrtc: Use the dtlssrtenc rtp-sync property
Instead of synchronising at the ICE transport, do clock sync for the
RTP stream at the DTLS transport via the dtlssrtpenc rtp-sync
property. This avoids delaying RTCP while waiting until it is time
to output an RTP packet when rtcp-mux is enabled.

2a3205b294 vulkan/window/win32: Don't post any WinProc message to parent window
Posting any message to parent seems to be pointless. That might break
parent window.
Regardless of the posting, parent window can catch mouse event
and also any keyboard events will be handled by parent window by default.

24d096597b vulkan: implement caching and reuse of a couple of vulkan resources
Includes a new GstVulkanHandlePool base class for pooling different
resources togther.  The descriptor cache object is ported to
GstVulkanHandlePool with the exact same functionality.

A new GstVulkanFenceCache is also implemented for caching fences
which is used internally by GstVulkanDevice for creating or reusing
fences.

The existing GstVulkanTrashFenceList object now caches trash objects.

Part 2 is a fullscreenrenderquad that is still in the plugin that
performs all of the previous vulkan-specific functionality.

a7c2aa473f vulkan/image: don't rely on weak-ref notifies for views
Weak refs don't quite work here correctly as there is always a race with
taking the lock between find_view() and remove_view().  If find_view()
returns a view that is going to removed by remove_view() then we have an
interesting situation.

In theory, the number and type of views for an image are relatively
constant and should not change one they've been set up which means that
it is actually practical to perform pool-like reference counting here
where the image holds a pool of different views that it can give out
as necessary.

3c5e5f8b85 adaptivedemux: fix 'utc now' gdatetime creation
It broke after removal of usage of GTimeVal that was deprecated,
it requires seconds in this unix-based creation instead of microseconds.

The downside here is that it will create an extra object just to be
discarded in order to add the microsecond part to it.

It would end up segfaulting as it would return a NULL value

c0561fb916 meson: Fix plugin symbol export for C++ sources/plugins
The symbol visibility=hidden flag was only being applied to C
compilation, so plugins implemented in C++ would leak extra symbols
than the 2 _get_desc() and _register().

That also showed that the gst-libs opencv C++ lib was not marking
symbols for export correctly because the BUILDING_GST_OPENCV define
wasn't in the C++ args, so fix that too.
