In my tests with the new GCC 14 compiler for Cerbero, I got the
following error:

Check and generate remote reception statistics from the info stored on
internal sources, as they are stored there when running against newer rtpbin
since MR !7424
This fixes cases where statistics are incomplete when
peers send RR reports from a single remote ssrc, which GStreamer does
when bundling is enabled and other RTP stacks may too.

In some cases, decodebin3 will send us incomplete caps (not containing
codec_data), and then a GAP event, which will force a negotiation.
This segfaults due to a null pointer deref because self->input_state
is NULL.
The only possible fix is to avoid negotiating when we get incomplete
caps (to avoid re-negotiationg immediately afterwards, which isn't
supported by some muxers), but also set as much input state as
possible so that a renegotiation triggered by a GAP event can complete
successfully.

This new LCEVC encoder plugin is meant to implement all LCEVC encoder elements.
For now, it only implements the LCEVC H264 encoder (lcevch264enc) element. This
element essentially encodes raw video frames using a specific EIL plugin, and
outputs H264 frames with LCEVC data. Depending on the encoder properties, the
LCEVC data can be either part of the video stream as SEI NAL Units, or attached
to buffers as GstMeta.

This new element wraps both the base H264 decoder and lcevcdec elements into a
bin so that LCEVC decoding works with auto-plugging elements such as decodebin.
By default, the H264 decoder element with higher rank is used as base decoder,
but any particular H264 decoder can be used by manually setting the base-decoder
property.

This new LCEVC decoder plugin is meant to implement all LCEVC decoder elements.
For now, it only implements the LCEVC enhancement decoder (lcevcdec) element.
This element essentially enhances raw video frames using the LCEVC metadata
attached to input buffers into a higher resolution frame. The element is only
meant to be used after any base decoder (eg avdec_h264).

There was an override to fake an IDR as soon as a SPS/PPS
is encountered, but that's not valid, at least an i-slice is needed.
Amend the visl result, as the output is slightly more correct, not
duplicating frame_num.

This improves the h264parse element to attach LCEVC enhancement data to buffers
using the new GstLcevcMeta API. This metadata will eventually be used downstream
by LCEVC decoders to enhance the RAW video frame.

This new metadata API allows elements to attach LCEVC enhancement data to video
buffers. Usually, the video parser elements are charged to parse the LCEVC
enhancement data from SEI Nal units (Supplemental enhancement Information).
However, other elements such as demuxers can also use this API if the LCEVC
enhancement data of the video is stored in a separate stream in the container.

D3D12_HEAP_FLAG_CREATE_NOT_ZEROED flag was introduced as of
Windows 10 May 2020 Update, and older versions don't understand
the heap flag. Checks the feature support and enables the
D3D12_HEAP_FLAG_CREATE_NOT_ZEROED only if it's supported by OS

The uvcsink was limited to only transfer YUY2 and MJPEG. For the
uncompressed formats there is no technical reason not to support them.
Since gst_video_format_to_string is already supporting more fourcc than
only YUY2 we use the default path in gst_v4l2uvc_fourcc_to_bare_struct
to create structures for more formats and bail out if the returned
format is not from the uncompressed type.
