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.

3089d142b0 ipcpipeline: introduce new plugin for inter-process pipelines
These elements allow splitting a pipeline across several processes,
with communication done by the ipcpipelinesink and ipcpipelinesrc
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.

3fe65ad854 tsmux: Store PES payload size in a 32 bit integer
While the size in the packet is only 16 bits, we need to handle bigger
sizes without overflowing. For video streams this can happen, 0 is
written to the stream instead.

This fixes muxing of buffers >= 2**16.

2cffa1579a jpeg2000parse: allow parsing when current caps are null
In this case, we assume that the format is jpc, and we infer the color
space from the number of components. This allows the parser to process a
jpc disk file coming from a filesrc element.

eebc4c0022 mpegdemux: segment seek flag is not relevant when checking for EOS
It is only relevant in deciding whether or not send SEGMENT_DONE.
In this case, not detecting EOS leads to a busy loop when encountering
the originally recorded end-of-file of a file that is still growing.

72b7794798 mxfdemux: Allow filler and other KLV packets between index table segments
While only filler packets should be allowed, for good measure also skip
any other KLV packets in the range where there could be index table
segments.

This fixes parsing of partitions with multiple index table segments,
which are separated by a filler packet, or other packets.

830e89b7e9 mxfdemux: Take temporal reordering from the index table into account
This is needed to know the PTS, without that we only know the DTS and
using that also for the PTS is wrong unless we have an intra-only codec.

If we can't get the temporal reordering from the index table, don't set
any PTS for non-intra-only codecs and let decoders figure out something.
