After talking with Vivia on IRC, she does not remember why the default
was FALSE and it is in my opinion preferable to stick to whatever
representation best represents time for a given framerate as a 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.

Should fix auto-generated follow-up sections like "Hierarchy" or
"Factory details" to be listed under the element name in the
table-of-contents of the document, instead of a stand-alone
"Duplex-Mode" section.
Also cleanup some spurious colon suffix after section names.

Now that nvidia-vaapi-driver appeared and isn't yet supported by GstVA, we've to
add an allowed list of supported drivers.
This patch implements it adding a environment variable to disable this driver
check: GST_VA_ALL_DRIVERS

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
recurse we could end up removing the wrong discoverer info from the
cache leading to freeing it while it was still discovering URIS, which
lead to the following assertion:

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.

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.

There is no guarantee that g_get_user_runtime_dir() is in a tmpfs. Using
an explicit shared memory API seems safer for all POSIX platforms.
Note that Android does not have shm_open() and only added memfd_create()
since API level 30 (Android 11).

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.

While the minimum timeout duration is 5s, checking only every 5s means
that we would notice this 4.9s too late in the worst case.
Checking once a second reduces this considerably while keeping the

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.
The patch is taken from freedesktop-sdk and was originally written by
Valentin David <valentin.david@codethink.co.uk>.

- Fixes a crash in tutorial 5, which happened when going back from video playback to the 'library' view, due to
ui_delegate already being destroyed at that point.
- Updates layouts to avoid navigation bar overlapping play/pause buttons. Colours are now correctly updated
based on light/dark mode being enabled, overall look and feel is improved with bigger buttons and paddings.
New button types are used, so target version is now iOS 15.0.
- Disables debug log coloring, as the default terminal in XCode does not render that anyway, so logs are now
more readable there.

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.
