The libwebp API doesn't match very well with the GstVideoEncoder
API, as it only delivers an unframed bitstream once all pictures
have been processed, which means we can only push a single buffer
manually on our srcpad on finish().
Supporting animated webp is still valuable, and the feature is
behind an opt-in property.

The output of VP9 and AV1 encoder is a little different from the H264
and H265 encoder, it may contain repeat frames and so the output frame
number may be more than the input. We need to call finish_subframe()
when some frame will be repeated later. So we need to extend the
current prepare_output() virtual function.

A client may map dmabufs without the intention to either read or write
to the memory. One example is clients wanting to use the
`gst_video_frame_map()` helper function.
Thus, in order to make buffers from `GstVaDmabufAllocator` conveniently
usable, ignore the modifier check if the client specified neither
`GST_MAP_READ` nor `GST_MAP_WRITE`.
Also skip the `va_sync_surface()` call in that case, as it's likely only
needed for CPU reads/writes.

According to https://datatracker.ietf.org/doc/html/rfc7587#section-7.1
those fields are sender-only informative, and don't affect

Fixes cases where the webrtc media will end up receive-only if the

Instead of only supporting writing SPU data directly to YUV frames,
render the SPU data to an intermediate AYUV overlay buffer. The overlay
data is then blended to the video frame.
For the PGS format, the overlay buffer size is set to the size of the
Composition Window, and its position in the overlay composition is set
to the window position. The objects to render are now cropped when the
cropping flag is set.
For the Vobsub format, the overlay buffer size is set to the size of the
Display Area.
Once rendered, the overlay composition rectangle is now moved and scaled
to fit the video output size, to avoid clipping.

- AU boundary detection reviewed to follow more closely H.264 spec. and more
specifically clauses 7.4.1.2.3 and 7.4.1.2.4.
- The gist of the changes is a look-a-head in then next AU required identify the
last vcl-nal of current AU and firt vcl-nal of next AU (according to
7.4.1.2.4) followed by the identification of the first nal of next AU
(according to 7.4.1.2.3).
- A backlog of all nals of current AU and next AU up to the point where current
AU can identified completed is kept.
- In NAL alignement mode vcl-nal are sent immediatly but the history is kept to
allow AU boundary detection. Non-vcl-nal can be delayed up to the reception of
the next vcl-nal to allow a correct AUD insertion.
- Based on this improved AU boudary detection we can avoid erronous AUD
insertion, like the one highlighted by test
test_parse_sliced_with_prefix_and_sei_nal_au.
- Add support for MVC AU boundary detection. (H.7.4.1.2.4)

required to identify boundary. (missing dependency_id and quality_id fields

With the way the runtime checks are currently set up, every single
openh264 release, no matter how minor, is considered an ABI break and
requires gst-plugins-bad recompilation. This is unnecessarily strict
because it doesn't allow downstream distributions to ship any openh264
bug fix version updates without breaking gstreamer's openh264 support.
Years ago, at the time when gstreamer's openh264 support was merged,
openh264 releases were done without a versioned soname (the library was
just libopenh264.so, unversioned). Since then, starting with version
1.3.0, openh264 has started using versioned sonames and the intent has
been to bump the soname every time there's a new release with an ABI
change.
This patch drops the strict version check. meson.build already has a
minimum requirement on openh264 version 1.3.0 where soname versioning
was added, which should be good enough to ensure that the library is
using soname versioning.

The original idea was to select the type of mapping (either using derive images
or downloading the image) in runtime, under the assumption that both methods
shared the same memory layout (offsets and strides), because a single
GstVideoMeta is assigned by the buffer pool at allocation time. Nonetheless, in
recent hardware this assumption is invalid, raising memory access errors.
This patch removes completely the mapping type selection at runtime, using the
method selected when the allocator is configured, synced with the bufferpool
allocation.
This problem was fixed originally for iHD driver only. But now it makes sense to
remove all of it.

There is an existing PMT mapping between PCR_%s and an mpegtsmux sink
pad name, where %s equals the program number that the PCR corresponds
to. We re-purpose this functionality to also support a mapping between
PCR_%s and an arbitrary PID. If this mapping is set, then the header PCR
PID is set to this value, and PCR is attached to the stream with this
PID.
Note: the current implementation also attaches PCR to the video stream,
so this may be inefficient.

analysis results relation using a bfs.
- Relation(edge) between analysis results (vertice) are stored in an adjacency-matrix
that allow to quickly identify if two analysis results are related and by
which relation they related. It also work for indirect relation
and can provide the path of analysis results by which two
analysis results are related.
- One allocation per buffer to store analysis results. Here we rely on
the application to guess how much space will be required to store all
analysis results. This is something that could be improved
significantly but it's a starting point.
- Define common analysis results, classification, object-detection,
tracking that are subclass of GstAnalyticRelatableMtd. The also
provide exemple of how to extend GstAnalyticRelatableMtd to have them
benefit for the mechanim to express relation with other analysis
results.

Even if IDXGIOutput6 says current display colorspace is HDR,
captured texture via IDXGIOutputDuplication::AcquireNextFrame()
is converted frame by OS unless we use IDXGIOutput5::DuplicateOutput1()
with DXGI_FORMAT_R16G16B16A16_FLOAT format, in order for captured
frame to be scRGB color space. Then application should perform
tonemap operation based on reported display white level, color primaries, etc.
Since we don't have any tonemapping implementation, ignores colorimetry
reported by IDXGIOutput6.

The code seems to validate that the media-level fingerprint matches
the fingerprint of the previous media or of the whole session. There
is no such requirement in any RFC I found. The session-session one
is just meant to act as a fallback when there is no media-level

This commit corrects the mapping relationship between RGB and BGR in GST and DRM.
The previous mapping was incorrect, causing potential color mismatches in the output.
The changes are as follows:
{WL_SHM_FORMAT_RGB888, DRM_FORMAT_RGB888, GST_VIDEO_FORMAT_BGR},
{WL_SHM_FORMAT_BGR888, DRM_FORMAT_BGR888, GST_VIDEO_FORMAT_RGB},

In the case of encoders and filters when importing a DMABuf, use
GstVideoInfoDmaDrm to get the drm fourcc and modifier.
In both cases, instead of keeping the original GstVideoInfoDmaDrm from caps, the
GstVideoInfo part of the structure is converted as canonical one, given the
format from the fourcc. It's kept in the way to handle V4L2 linear DMABufs and
to avoid too many changes in the current code.

Instead of guessing the DRM format and modifier, pass a DRM video info to
gst_va_dmabuf_memories_setup().
Still, it checks for the DRM parameters in DRM info, if they are not available,
as in the case of V4L2 buffers, the part of the video info is used.
This is an API breakage, but since the plugin is still in stage, it's still
allowed.

To import DMAbufs we used VASurfaceAttribExternalBuffers which works, but it's
not specific for DRM PRIME 2, since it lacks of many metadata. This patch
replaces VASurfaceAttribExternalBuffers with VADRMPRIMESurfaceDescriptor in

Still, this patch assumes linear modifier only.
The hack for RGB surfaces in I965 driver was pushed down into
va_create_surfaces() to avoid handling both structures.

Suppose you have a project where GStreamer and wayland-protocols are
pulled in as dependencies via .wrap files. In that case, Meson's setup
step will fail for gst-plugins-bad with the message "Sandbox violation:
Tried to grab file viewporter.xml outside current (sub)project." To
avoid this exception, one should use Meson's `files` and `join_paths`
functions. The suggested solution is identical to how GTK 4 processes
Wayland files.

A payload of 0x80 0x80 means that it's padding. It's not a good idea to
throw this away though, because of the cc_valid field.
According to CEA 10-B section 25.2.1, if cc_valid is zero, the run-in
clock and start bit should not be generated. In practice, this means
that any closed captions will be erased and the end-user TV will show
that captions are not available for this stream. This might have
undesired consequences, e.g. we were just showing a long line of
captions and we disable it before the user has had time to read it, or
you can't enable closed captions during silence/music intervals.
We cannot reliably detect whether there's a currently-silent closed
caption stream or just nothing, but we have this information coming from
upstream, so we can at least not discard it.

When decoding stream using hardware V4L2 decoder element, in any of the
currently supported formats, the decoding will fail once frame number
1000000 is reached. The reported error clearly indicates a wrap-around
occured, instead of receiving decoded frame 1000000, frame 0 is received
from the hardware V4L2 decoder driver.
The problem is actually not in the driver itself, but rather in gstreamer,
which uses `struct v4l2_buffer` member `.timestamp` in a special way. The
timestamp of buffers with encoded data added to the SINK (input) queue of
the driver is copied by the driver into matching buffers with decoded data
added to the SOURCE (output) queue of the driver. In fact, the timestamp
is not a timestamp at all, but rather in this special case, only part of
it is used as an incrementing frame counter.
The `.timestamp` is of type `struct timeval`, which is defined in
`sys/time.h` [1]. Only the `tv_usec` member of this structure is used
for the incrementing frame counter. However, suseconds_t tv_usec [2]
may be limited to range [-1, 1000000]:
"
[XSI] The type suseconds_t shall be a signed integer type capable of
storing values at least in the range [-1, 1000000].
"
Therefore, once frame 1000000 is reached, a rollover occurs and decoding
fails.
Fix this by using both `struct timeval` members, `.tv_sec` and `.tv_usec`
with matching modular arithmetic, this way the failure would occur again
just short of 2^84 frames, which should be plenty.

This pair of elements, inspired from shmsink/shmsrc, send unix file
descriptors (e.g. memfd, dmabuf) from one sink to multiple source
elements in other processes.
The unixfdsink proposes a memfd/shm allocator, which causes for example
videotestsrc to write directly into memories that can be transfered to
other processes without copying.

The src caps of the libde265 is now fixed to I420, and so if the
stream is other format, such as 4:4:4 or 10 bits format, the pipeline
will crash because the dowstream element accesses the video buffer as
I420 format.
We now restrain the input caps to "main" profile, which only contains
4:2:0 8 bits stream.

This can happen with the dummy "noopenh264" library that the freedesktop
flatpak runtime ships, and Fedora is planning on shipping as well. In
both cases the dummy implementation gets replaced with the actual
openh264 library that's downloaded directly from Cisco, but just to be
on safe side, this patch makes it careful to check the return values to
avoid crashing if the underlying library hasn't been swapped out yet.

If users update geometry related properties very frequently
for a stream to be animated, redrawing on every update
can make rendering choppy or can be a performance bottleneck.
To address the issue, adding a property to control the behavior
of redrawing scene when geometry related properties are updated.
Also, do not resize swapchain on such property update, since
re-allocating backbuffer and multi-sampled render target is
unnecessary in that case.

This element refactors functionality from gstonnxinference element,
namely separating out the ONNX inference from the subsequent analysis.
The new element runs an ONNX model on each video frame, and then
attaches a TensorMeta meta with the output tensor data. This tensor data
will then be consumed by downstream elements such as gstobjectdetector.
At the moment, a provisional TensorMeta is used just in the ONNX
plugin, but in future this will upgraded to a GStreamer API for other
plugins to consume.
