b8b4124c8b netsim: add "allow-reordering" property
Reordering of packets is not very common in networks, and the delay
functions will always introduce reordering if delay > packet-spacing,
so by setting allow-reordering to FALSE you guarantee that the packets
are in order, while at the same time introducing delay/jitter to them.

531b1e326f netsim: Change max-delay to be inclusive
It is more intuitive for the user that in order to acheive a constant
delay min-delay and max-delay are equal.

9416d36463 netsim: Add "delay-distribution" property plus normal distribution
By using the property "delay-distribution" the user can control how the
delay applied to delayed packets is distributed. This is either the
uniform distribution (as before) or the normal distribution.

"min-delay" and "max-delay" control both distributions. For the normal
distribution it defines the bounds of the 95% confidence interval.

5187fdfb07 netsim: remove private struct and padding
There's no need for these things, since the plugin headers
are not public, and all the extra ->priv-> just clutter the
code.

93d29e8030 h265parse: early set src caps when input not byte-stream
When input is not in byte-stream format there is no need to wait for the first
buffer before setting src caps. We already have all the information from the
input codec_data.

This allow us to already configure downstream elements allowing them,
for example, to already allocate their internal buffers as they know
the format of the input they are about to receive.

Same change as the one I just did in h264parse.

00874850e7 h265parse: put downstream caps first if possible on sink caps
Try prioritizing downstream's caps over upstream's if possible so the
parser can configured in "passthrough" if possible and save it from

f3b539e0ff avwait: Deserialised timecodes set after caps event now get correct framerate
A deserialised timecode has a framerate of 0/1 by default. That breaks
it when comparing the frames field with another timecode (incoming from
the frame). We were setting the framerate when receiving the caps event,
but not when setting the timecode in set_property, so it was broken for
timecodes set after the caps event.

Also checking if the fps_n we got from the caps event is != 0 before
setting it - also at the caps event.

38120376c6 avwait: Better handling of deserialised timecode framerates
Now that timecodes support proper serialisation / deserialisation, a
timecode might have an invalid fps_n / fps_d even without using the
target-time-code-string property. Detect those cases and set fps_n/fps_d
properly.

503403ff0a avwait: Fix crash when explicitly setting end_tc to NULL
If end_tc is NULL, it means that we don't want avwait to stop at any
timecode. When explicitly setting end_tc to NULL, there is no point in
comparing end_tc with start_tc (to see if we'll reject end_tc for being
before start_tc), so the check in question is completely disabled
instead of letting it crash.

Add support for parsing linear time code from
an audio source using libltc

The user can now choose between 3 different and independently
running timecode sources. The old override-existing property
has been replaced by timecode-source.

a160b85f0a avwait: Added end-timecode property
avwait can now be configured to stop when a given timecode has been
reached. It will start at the timecode indicated with start-timecode and
end at the timecode indicated with end-timecode. If end-timecode is
NULL (default), the previous functionality is preserved: keep going and
not end.

52d0ef2665 tsdemux: Make jp2k handling more robust and efficient
* Avoid copying the pending data and instead create a buffer directly from
  that data with the appropriate offset.
* Locate the jp2k magic to determine the exact location of the (first) frame
  data instead of assuming that the header is of an expected size

c393f0d768 tsdemux: Handle quirk in jp2k es header handling
The jp2k specification (ITU-T T.800) specifies that the 'brat' box
has two fields and the second one (AUF2) can be set to 0 for progressive
streams.

The problem is that the mpeg-ts specification (ITU-T H.222.0 06/2012)
says that the AUF2 field is only present if the stream is interlaced

In order to cope with both situation, accept those next 32bit if the
stream is marked as progressive and those bits contain 0

806ff70590 compositor: Add support for crossfade blending
Crossfading is a bit more complex than just having two pads with the
right keyframes as the blending is not exactly the same.

The difference is in the way we compute the alpha channel, in the case
of crossfading, we have to compute an additive operation between
the destination and the source (factored by the alpha property of both
the input pad alpha property and the crossfading ratio) basically so
that the crossfade result of 2 opaque frames is also fully opaque at any
time in the crossfading process, avoid bleeding through the layer
blending.

Some rationnal can be found in https://phabricator.freedesktop.org/T7773.

These elements allow splitting a pipeline across several processes,

elements. The main use case is to split a playback pipeline into
a process that runs networking, parser & demuxer and another process
that runs the decoder & sink, for security reasons.
