This meta hold one buffer of the same codec data as the parent memory. This
extra frame luma will be used as the alpha values for the final combined
frame. This is notably used to support VP8/VP9 alpha as defined in WebM and
matroska specification.

Otherwise real-time clock changes can wrongly trigger timeouts, or not
cause timeouts to happen in time.
Unfortunately real-time clock times still have to be kept track inside
the elements for the statistics. Switching those over to the monotonic
clock would cause behaviour changes from the application point of view.
The statistics are extended with fields with monotonic times though.

These work the same way as the corresponding properties on queue and
allow to control the internal buffer size of the appsrc in a more
flexible way.
Unlike in queue the max-buffers and max-time properties are 0 (i.e.
disabled) by default for backwards compatibility reasons.

Cropping was not handled properly when frames have to be copied to
xvimage's buffer pool, first because the crop meta were dropped, and
second because the allocated frame size in xvimage's buffer pool were
smaller than the incoming frame.
This patch updates xvimagesink's video info when propose_allocation()
is called, and copies the GstVideoCropMeta from source frame to
destination one.

Buffer pool is created every time setcaps() is called, but it's
required only when upstream doesn't use it, so it's only needed to
copy frames onto XV buffers.
This patch delay the creation of the buffer pool until it's frame copy
is required.

uridecodebin assumes that refcount of decodebins stored in pending_decodebins
are floating but it might not be true in case that refcount of the decodebin
was touched in other places. To avoid the floating refcount issue,
hold strong reference.

Lookup will now maintain the full list of possible IP address(es).
We can now iterate over all available addresses in case certain
address families (IPv6) are disabled or try connecting to additional
addresses for the clients.

`@` references are used to reference function parameters, struct members
or enum variants _within_ the current type/function. It cannot and
should not be used to reference to types outside that.
Since C has no notion of member functions it makes little sense to
prefix these with `@`; most of the documentation here was referencing
functions on _different_ types anyway.

Like other foobarA variant APIs on Windows, formatted string
by strftime() is ANSI string, not unicode encoded one.
It would be problematic for non-english locale systems.
We should use unicode version API (wcsftime in this case)
whenever it's possible on Windows.

If the alsasink thread starts the write loop but another thread pauses
the underlying alsa device, the sink thread will endlessly loop.
snd_pcm_writei() will return 0 if the state is SND_PCM_STATE_PAUSED
and the loop will never make any progress.

Table 1.10 – "Levels for the AAC Profile" only goes to 5 max channels
/ 7 max channel post amendmend, so I assume the number of channels
should not include LFE, otherwise there's no valid level for 5.1 resp.
7.1 (post amendmend)
