gststructure: Add gst_structure_get_flags method

We don't prevent setting G_TYPE_FLAGS on GstStructure
but no helper method for getting the value.
Add a method similar to gst_structure_get_enum()

aggregator: Reset EOS flag after receiving a stream-start event

And also don't assert that there are no buffers queued up when handling
an EOS event. The pad's streaming thread might've already received a new
stream-start event and queued up a buffer in the meantime.

This still leaves a race condition where the srcpad task sees all pads
in EOS state and finishes the stream, while shortly afterwards a pad
might receive a stream-start event again, but this doesn't seem to be
solveable with the current aggregator design.

These patches are taken from upstream, and they fix compile failures

This is currently causing a warning because we do not require the
version of meson that ships with this feature: 0.63.0. The version has
not been bumped because older Meson versions gracefully ignore the
wrap field, this fix is optional and only needed on macOS, and 0.63.0
is a very new release with a bug that partially breaks this feature:

https://github.com/mesonbuild/meson/pull/10602

We can consider bumping the requirement once 0.63.1 is released.

webrtcbin: Add a signal to plug bandwidth estimator elements

We need GStreamer elements to do the bandwidth estimation as this way
they can also control the pacing of the transmission flow as specified
 in the [GCC] algorithm for example.

Bandwidth estimator element are placed right before the "RTPSession" as
an "rtp-aux-sender" element. This way they can use the "Transport-wide
Congestion Control" RTCP feedback messages through the "RTPTwcc" custom
events that are sent by the rtpsession.

Applications are responsible to react to the bandwidth estimator element
and set the encoder target bitrate etc... which means that we can not
pass an estimator as an element factory, so a signal as been chosen
instead.

d3d11converter: Add support for GstVideoOrientationMethod

Shader can handle rotation/flip with other conversions
at once in a single pipeline, and depending on device
capability, videoprocessor may support it too.

d3d11videosink: Use single GstD3D11Converter object

GstD3D11Converter supports videoprocessor and texture upload.

d3d11memory: Add private method for texture wrapped memory allocation

Unlike public method gst_d3d11_allocator_alloc_wrapped(), newly
added method by this commit will not calculate CPU accessible memory
size, since staging texture must be allocated to calculate the size.

d3d11convert: Use single GstD3D11Converter object

... and don't use GstD3D11VideoProcessor. Now GstD3D11Converter will
be able to convert using videoprocessor, and texture upload is also supported by
GstD3D11Converter. All the noisy code can be removed therefore.

d3d11converter: Add support conversion using videoprocessor

* Add videoprocessor feature to d3d11converter, in order to unifiy
  conversion flow.
* Add convert_buffer() method to support automatic shader/videoprocessor
  selection. The method also supports texture upload if input memory
  cannot be used for conversion (e.g., system memory or so)

samiparse: clean up some GString usage

There's no need to re-assign the return value of
g_string_append_*() functions and such to the variable
holding the GString. These return values are just for
convenience so function calls can be chained. The actual
GString pointer won't change, it's not a GList after all.

samiparse: micro-optimise entity handling

Avoid relocations and hard-code entity string length

samiparse: fix handling of self-closing tags

We would check the wrong string (rest of line rather than element)
for the / suffix of self-closing tags, which is not only wrong but
also has atrocious performance with certain strings like the garbled
nonsense clusterfuzz feeds us, which might cause discoverer to time
out when processing garbled SAMI files.

Revert "glupload: Fix caps query with no filter"

This reverts commit 6f9ae5d7580763b5d18badb76f2166ff0012886a.

The _transform_caps() function can't tell the difference
between the caller wanting to know the output caps
for the current method, or all possible output caps. If
it includes caps for all possible methods, glupload can
end up negotiating and sending the wrong output caps
downstream.

Partially reverts !2687
Fixes #1310

decklinkvideosink: Pass video frames directly to the Decklink SDK without copying

If the video frame is stored in PBO memory then we need to copy anyway as

nvencoder: Add support for dynamic GPU device selection

Adding nvautogpu{h264,h265}enc class which will accept upstream logical
GPU device object (GstCudaContext or GstD3D11Device) instead of
using pre-assigned GPU instance.

If upstream logical GPU device object is not NVENC compatible
(e.g., D3D11 device of non-NVIDIA GPU) or it's system memory,
then user specified "cuda-device-id" or "adapter-luid" property
will be used for GPU device selection.

cuda: Add YUY2 and UYVY formats for GL interop

cudadownload: Passthrough in case of CUDA -> SYSTEM

GstCudaMemory supports CPU access via CUDA pinned host memory already
and it would show faster memory transfer performance between
GPU and CPU than copying from/to normal system memory.
If downstream supports video meta, we can passthrough CUDA memory.

glupload: Fix caps query with no filter

If no filter caps are provided with a caps query, always
generate a full set of all caps from all upload methods,
not just the configured one. This is needed to handle
renegotiation when dealing with raw sysmem caps - as the upload
method might accept raw sysmem caps, but only the raw data
uploader adds those to the caps query.

Revert "glupload: allow system memory for dmabuf in transform_caps"

This reverts commit f3292dc1561a8d62812c3f1a2bb3de5c5bb6a807.

Only the raw data uploader should add sysmem caps to the
actual caps query, because we want them to be at the
lowest priority. If upstream does select to send raw
caps, then the correct upload method will still
be chosen because the accept_caps implementation
will accept them

gl: Don't use the full transform_caps() method for reconfiguration check

When checking if we need to reconfigure when uploading, check
specifically the output caps of the current method will
result in compatible/incompatible caps, not the full set
of output caps from all upload methods.
