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`.

By sealing for future writes, we broke Wayland SHM support. It seems like the
wayland library maps the SHM in read/write mode. This is visible through no
display and an error message like this:
wl_shm@7: error 2: failed mmap fd 43: Operation not permitted

Take the case into account when user filters have been set before the
source gets updated.
Note that the further linking of the filters, if present, happens below
in the `gst_camera_bin_check_and_replace_filter()` calls.
The audio filter is still affected by the same issue but left out for
now.

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.
Also handling setting / resetting of the media clock and pipeline clock
correctly by resetting the media clock's state accordingly.

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
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
fingerprint.

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},

After talking with Vivia on IRC, she does not remember why the default

behavior.

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
va_create_surfaces().
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.

When a new discoverer was created for a thread so discovery could

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
need to periodically clean-up the unused discoverers.

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.
