re-add gst-plugins-rs.wrap

It's been lost during the monorepo migration.

Note that building Rust plugins as a subproject is currently broken,
https://gitlab.freedesktop.org/gstreamer/gst-plugins-rs/-/issues/171

vtenc: Add FieldDetail properties for interlaced input

Standard interlace handling:
* If we have interlace-mode=interleaved and the field order, we just
  set it when creating the session
* If we have interlace-mode=(interleaved|mixed) and no field order, we
  set the field order on the first buffer

The encoder session does not support changing the FieldDetail after it
has started encoding frames, so we cannot support mixed streams
correctly.

va: Delay decoders downstream negotiation.

Delay decoders downstream negotiation just before an output frame
needs to be allocated.

This is required, are least for H.264 and H.265 decoders, since
codec_data might trigger a new sequence before finishing upstream
negotiation, and sink pad caps need to set before setting source pad
caps, particularly to forward HDR fields. The other decoders are

va: Move back parent_object to each element.

Using GstBaseDec hack to access the parent_object of each element in
the element itself is a bit fragile. It would be better to keep its
own parent object as the usual global variable. It would make it

The GstBaseDec macro to access the parent object now it's internal to

We were checking if the start time of the gap event was

cccombiner: stop attaching caption buffers when caption pad has gone EOS

When schedule is true (as is the case by default), we insert padding
when no caption data is present in the schedule queue, and previously
weren't checking whether the caption pad had gone EOS, leading to
infinite scheduling of padding after EOS on the caption pad.

Rectify that by adding a "drain" parameter to dequeue_caption()

In addition, update the captions_and_eos test to push valid cc_data
in: without this cccombiner was attaching padding buffers it had
generated itself, and with that patch would now stop attaching
said padding to the second buffer. By pushing valid, non-padding
cc_data we ensure a caption buffer is indeed attached to the first
and second video buffers.

assrender: Fix mimetype detection

Previously gst_structure_has_name was used to get a string to compare with supported mimetypes.
This is incorrect as above function returns a user defined structure name which is
not the structure mimetype value.

matroska: Set image/attachment structure mimetype

Set structure mimetype to fix data detection by mimetype in other plugins.

matroska: Treat non-image structure as attachment

Otherwise each structure is named as GstTagImageInfo even if
it does not contain any images which is misleading.

rtpbin: fix leak of pad when a fec encoder and aux sender a created

The ghost sink pad retrieved by rtpbin from the aux sender was not freed
when there was a previous element (fec encoder) in the chain.

ci: gstreamer-full: remove static build

The gstreamer-full jobs act as
static builds,  no need to perform it twice.

gstreamer-full-minimal can be nodebug.

README: Remove outdated Windows ARM64 related comment

interlace: Replace custom lock with object lock

The object lock is sufficient for the task of protecting against
object property data races.

Avoid blatant data races here.

interlace: Reset after changing state to READY

Trying to reset before the pads have been deactivated races with the
streaming thread. There was also a buggy buffer clear leaving a dangling
`stored_frame` pointer around. Use `gst_interlace_reset` so this happens
properly.

nvh264enc: add constrained-baseline to the caps profiles

In practice, when baseline is requested from the encoder it
produces constrained baseline, and it is already reflected
in the profile-iop flags.

mediafoundation: Fix for UWP build

We don't support D3D11 interop for UWP because some APIs
(specifically MFTEnum2) are desktop application only.
However, the code for symbol loading is commonly used by both UWP and WIN32.
Just link GModule unconditionally which is UWP compatible, and simply don't
try to load any library/symbol dynamically when D3D11 interop is unavailable.

Revert "ci: Split base and core valgrind on different runners"

Those job are not the ones that take most time in normal run (they
where when running with --n-runs) and that leads to using more runners
which might be a problem at this point.

This reverts commit 4ad22b05a15056b9e85468af266bacc7d3758ee9.

mms: remove mmssrc plugin

Doubtful that anyone still needs that or there are even
any streams left out there.

MMS was deprecated in 2003 (in favour of RTSP) and support for
it was dropped with Microsoft Media Services 2008.

streamsynchronizer: set running time offset on events

It's cleaner and more generic than overriding the qos events.

concat: fix qos event handling

We were shadowing the sinkpad variable resulting in:

- the pad to be leaked

meson: update for dep.get_pkgconfig_variable() deprecation

... in favour of dep.get_variable('foo', ..) which in some

extract variables from pkg-config dependencies as well as
internal dependencies using this mechanism.
