We ship a vpx wrap now, and we need to explicitly pass options to
glib-networking and libnice.
Also, ensure that we're building the right GL API/winsys/platform.
This sets a default to protect us from stray Homebrew installations
with XQuartz.

null event NT handle to ID3D12Fence::SetEventOnCompletion()
will block the calling CPU thread already, thus it has no point that
creating an event NT handle in order to immediate wait for fence at CPU-side.
Note that passing a valid event NT handle to the fence API might be useful
when we need to wait for the fence value later (or timeout is required),
or want to wait for multiple fences at once via WaitForMultipleObjects().
But it's not a considered use case for now.

GstD3D12Window.priv.input_info is referenced by mouse event handler
in order to calculate corresponding original position
if scene is rotated/flipped by the videosink.

The driver - AKA intel-vaapi-driver - has been unmaintained for four years
now and encoding appears to be broken in various cases. As it's unlikely
that the situation will improve, blocklist the driver for encoding.
Decoding appears to be stable enough to keep it enabled.
The driver can still be used by setting the `GST_VA_ALL_DRIVERS` env
variable.

GstFFMpegAudDec.context can be nullptr if decoder got closed
without opening new context. Note that we don't need to clear
AVCodecContext.extradata there since avcodec_free_context()
will do clear the data if needed.

The driver frame counters (processed, dropped, buffer level) are not
always correct apparently, and don't allow reliably assigning a frame
number to captured frames.
Instead of relying on them, count the number of frames directly here and
detect dropped frames based on the capture times of the frames: if more
than 1.75 frame durations are between two frames, then there must've
been a dropped frame.

Define a default usage and use it instead of repeating the same bitwise
addition.
Therefore, when usage is defined as zero, the usage is defined with the
format's supported usage and the default usage, now without the storage
bit, but with color and input attachment bits.

Not doing so would mean that tags would be overidden by any tag events sent by
upstream. Also only send a tag event directly if upstream never sent one.
By default use GST_TAG_MERGE_REPLACE to override tags that exist in both the
upstream event and this element with the ones from this element, but provide a
new "merge-mode" property to adjust the behaviour.

avcodec_close() is deprecated and it's not supported anymore to re-open
a codec, so we only ever allocate the codec in set_format() now and
always free it after usage.
As part of this, also fix various memory leaks in related code paths.

Direct access to AVInputFormat::read_probe() is not possible anymore
with ffmpeg 7.0, and the usefulness of this typefinder seems limited
anyway. An alternative implementation around av_probe_input_format3() or
similar would be possible but it would be going over all possible ffmpeg
probes at once.
Having a typefinder here means that basically every application will
load the gst-libav plugin when typefinding is necessary, which has
unnecessary performance impacts. If a typefinder from here was indeed
missing from typefindfunctions in gst-plugins-base then it would be
better to add it there directly.

If a d3d12 memory holds non-direct-queue fence but the fence was
created with D3D12_FENCE_FLAG_SHARED flag, use the fence instead of
waiting for fence at CPU side. Note that d3d12ipcsrc or
d3d12screencapture elements will hold such sharable fence.

When building for iOS in Cerbero, as of MoltenVK SDK 1.3.283, we have
to statically link to libMoltenVK since it no longer ships a dylib.
This requires linking to libc++, so we find the dep with the objc++
compiler to ensure that meson uses the right linker.
