When the subclass attempts to finish without an explicit `out_buffer`,
we take a buffer from our adapter. We need to make this buffer writable
before copying the metadata.
This led to data races such as in the following pipeline, which randomly
messed up the buffer PTS:
gst-launch-1.0 -e audiotestsrc timestamp-offset=5555 num-buffers=100 \
! opusenc ! tee name=t ! queue ! opusparse ! fakesink silent=0 \
t. ! queue ! opusparse ! fakesink silent=0 -v | grep '0000, dur'

The tags and caps were leaked for unknown streams, I'm not sure they'd be valid
in that case, but better safe than sorry.
The tags ownership is transfered when calling `gst_adaptive_demux_track_new()`
so unreffing those afterwards was a mistake.

We were previously always querying index 0, and while the number of planes per
buffer will never change, it seems more proper to query the right buffer rather
than always the first one.
This was found while reading strace logs, and wondering why the
V4L2_BUF_FLAG_MAPPED flag was present on all ¬0 indices even though that
happened before VIDIOC_EXPBUF.

- GstAnalyticRelationMeta is a base class for analytics
meta. It's able to store analytics results (GstAnalyticRelatableMtd)
and describe the relation between each analysis results.
- GstAnalysisRelationMeta also contain an algorithm able to explore
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.

Whenever that caps changes does not imply that a new segment will start.
Don't reset the last_ts if only the caps have changed. This fixes issues
if you have a stream without only first frame with TS=0, and have resolution

described in #1352. The reported issue is still fix after this change.

The fake video decoder ignores input bitstream except
to enforce caps restrictions. It reads video width,
height and framerate from caps. Then it just pushes
video frames without doing any decoding.
The fake video decoder just draws a snake moving from
left to right in the middle of the frame. This is a
light weight drawing while it still provides an idea
about how smooth is the rendering.
The fake video decoder inherits from GstVideoDecoder.
It is useful to measure how smooth will be the whole
rendering pipeline if you had the most efficient video
decoder. Also useful to bisect issues for example when
suspecting issues in a specific video decoder.
Handles mpeg2, mpeg4, h263, h264, theora, vp8, wmv3, msmpeg,
flash-video, vp6, vp9, wmv1, wmv2, divx but more can be
added if needed.
For now it can only output RGBA, RGBx, BGRA, BGRx.
Its rank is 0 (none) but I added a property to change it so
that it can be selected by decodebin.

From a multimedia perspective GLES >= 2 has the big advantage of
supporting external textures (`OES_EGL_image_external` /
`OES_EGL_image_external_essl3`), allowing various YUV formats to be
imported directly by drivers.
It appears unlikely by now that the extension will ever be ported to
GL with Vulkan becoming more popular, leaving GL without an "official"
way to import YUV formats.
Further more, for Gst internal purposes it's likely that GLES2 works
equally well if not better on most drivers these days, especially on
embedded devices.
Thus switch the default for EGL context creation to GLES2. This won't
affect apps that create their own context, but `gst-launch-1.0` etc.,
which are often used for testing so people don't have to pass
`GST_GL_API=gles2`.

Take the case into account when user filters have been set before the

If this property is enabled then the jitterbuffer will do the normal PTS
calculations according to the configured mode instead of making use of
the RFC7273 media clock.
The timestamp calculated from the RFC7273 media clock will only be
stored in the reference timestamp meta, if addition of that meta is enabled.
Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/5512>
When this property is used, it is assumed that the system clock is
synced close enough to the media clock used by an RFC7273 stream.
As long as both clocks are at most a few seconds from each other this
will give the correct results and avoids having to create an actual
network clock that has to sync first.
If the system clock is actually synchronized to the media clock then
everything will behave exactly the same, otherwise the reference
timestamp meta will be correct but the buffer timestamps will be off by
the difference between the two clocks.
Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/5512>
Do more checks for clock equality than just checking pointers. The same
NTP/PTP clock might be used as pipeline clock but a new instance, so
instead also check what clock they are synced to.

This allows configuring the TTL that is used for multicast packets sent
out on the sockets, and is defaulting to 1 as before. The default might
change at some point.
In some networks multiple hops are needed to reach the PTP clock and
this allows to configure GStreamer in a way that works in such networks.
At a later time, per-domain or per-interface TTL configurations might be
added when needed.

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.

Because we treat raw audio chunks/samples as keyframes, they were interfering
with seek time adjustment.
Became apparent when the accompanying video stream was I-frame only,
for example ProRes.
Since raw audio streams can be seeked freely, it's fine to just ignore them here,
giving priority to the real keyframes in the video stream.

The code seems to validate that the media-level fingerprint matches

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

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.

If text width ever reached 1px, for example after resizing the output window, the overlay would stop rendering
and never return again. The 1px condition itself does not seem to make much sense here anyway.
This was a chain of events: width reached 1, so the composition was set to NULL. Then, after resizing the output window,
push_frame() was called but would not attempt to renegotiate because composition is NULL. This caused the width/height
to never be updated again, as that only happens during negotiation, so the overlay was gone for good.

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.

In rare cases - notably on macOS, because of multiple GL contexts - the lack of a sync point was causing overlays
to disappear for a frame after being redrawn, or sometimes not appear at all. This change makes sure that the display
in one GL context will be correctly synchronised with the other GL context where the overlay texture was uploaded.

The manager keeps track of one discoverer per thread and in large applications
with hundreds of threads this can significantly increase memory pressure. So we

When using deeply nested timelines with the `ges:` protocol the
formatters ends up trying to do discovery from the same thread current
discovery happens, leading to infinite freeze as GstDiscoverer can't run
several discoveries at the same time.
By ensuring that when calling `gst_discoverer_discover_uri_async` no
`GstDiscoverer` is set as "thread discoverer" we know that another
discoverer will be created if discovery recurses, effectively removing
the freeze.

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.

It's a bad idea trying to mix the Options from GStramer and
GTK, in addition with cli argument being a bit wonky thing for
GUI applications in general. In the rare, now, occasion
that an application wants to parse arguments, its preferable
to parse them manually and use library apis afterwards
rather than trying to combine the option groups and hope it
works.
In addition, applications should be opening files using
`g_application_open` instead of parsing random arguments.
