4b77a0a681 added a new consumer of ff_scale_adjust_dimensions
which was recently modified to allow for square pixel output.
This commit extends the new option to vpp_amf, and unbreaks the building
of vf_amf_common.c
For anamorphic videos, enabling this option leads to adjustment of
output dimensions to obtain square pixels when the user requests
proportional scaling through either of the w/h expressions or
force_original_aspect_ratio.
Output SAR is always reset to 1.
Option added to scale, scale_cuda, scale_npp & scale_vaapi.
libplacebo already has a similar option with different semantics,
scale_vt and scale_vulkan don't implement force_oar, so for these
three filters, I've made minimal changes needed to not break building
or change output.
IVTV, a Linux driver for TV tuners, and V4L2 utilize
a coding named after IVTV to carry sliced VBI data
in MPEG streams produced by tuner cards with
VBI capture capability and an MPEG-2 encoder SoC.
IVTV or V4L2 driver will transport the coded data into a
MPEG-PS private stream ("IVTV") that can be captured
from the card alongside the video/audio.
The data could include:
EIA-608, Teletext, WSS (PAL widescreen signaling),
or VPS (PAL VCR signaling).

Here is a proposed patch for portability of doc/t2h.pm for GNU Texinfo
7.1 and 7.1.90 (7.2 pretest). I tested against 7.1 and 7.1.90 (7.2
pretest). There is a difference in the headings compared to the website
version, maybe related to FA_ICONS not being set the same, but the
result seems correct.
I also renamed $element to $output_unit in ffmpeg_heading_command as in
new equivalent makeinfo/texi2any code the $element variable is the
$command variable in ffmpeg_heading_command, which is very confusing. I
left as is the $command variable to have a patch easier to read, but it
could make sense to rename $command as $element later on.
The patch could also have effects with Texinfo 7.0, since some of the
changes are for that version, but that probably never show up because it
is for situations that may not exist in ffmpeg manuals (for example
@node without sectioning command), or because the code is robust to some
missing information (case of $heading_level in ffmpeg_heading_command
that was not set, as far as I can tell).

In f121d95, the outlink framerate was unconditionally unset.
This breaks/bloats outputs from CFR muxers unless the user explicitly
sets a sane framerate. And the most common invocation for setpts seen in
workflows, our docs and across the web is `PTS-STARTPTS` or others of the
general form `PTS+constant` which preserves the input framerate.
Default value is false, which restores old behaviour.
Fixes#11428
This blocks disallowed extensions from probing
It also requires all available segments to have matching extensions to the format
mpegts is treated independent of the extension
It is recommended to set the whitelists correctly
instead of depending on extensions, but this should help a bit,
and this is easier to backport

These properties are unreliable because they depend on the frames decoded so
far, users should check directly the presence of the decoded AVFrame side data

libjxl supports animated encoding, so we add a wrapper to the
library using the receive_packet callback method.
This code was based largely on a patch sent by Zsolt Vadász,
although it was updated to use more recent coding practices
and many of the leaks and issues were fixed.

As discussed in the previous commit, we often need a convenient way of
stripping all side data related to a certain aspect of the frame. This helper
accomplishes just that.
I considered also adding a way to match only side data matching *all*
properties, but I think this is sufficiently useless in practise to not warrant
inclusion in the API.
Many filters modify certain aspects of frame data, e.g. through resizing
(vf_*scale* family), color volume mapping (vf_lut*, vf_tonemap*), or
possibly others.
When this happens, we should strip all frame side data that will no
longer be correct/relevant after the operation. For example, changing
the image size should invalidate AV_FRAME_DATA_PANSCAN because the crop
window (given in pixels) no longer corresponds to the actual image size.
For another example, tone-mapping filters (e.g. from HDR to SDR) should
strip all of the dynamic HDR related metadata.
Since there are a lot of different side data types that are affected by such
operations, it makes sense to establish this information in a common, easily
accessible way. The existing side data properties enum is a perfect fit for
this.
This setting can be used to infuence the type of tone and gamut mapping used
internally when color space conversions are required. As discussed at VDD'24,
the default was set to relative colorimetric clipping, which is approximately
associative, surjective and idempotent. As such, it roundtrips well, although
it is strictly speaking not associative on out-of-gamut colors.
This can be useful in other places, e.g. it can replace objpool in
fftools.
The API is modified in the following nontrivial ways:
* opaque pointers can be passed through to all user callbacks
* read and write were previously separate callbacks in order to
accomodate the caller wishing to write a new reference to the FIFO and
keep the original one; the two callbacks are now merged into one, and
a flags argument is added that allows to request such behaviour on a
per-call basis
* new peek and drain functions
Currently, ffprobe has two stream-level fields that do not work,
closed_captions and film_grain).
Their value is always 0 because ffprobe cannot access the internal
codec properties when it is setting up its stream contexts.
In this commit, add the new option -analyze_frames to ffprobe,
allowing the user to read frames up to the interval they have defined
and fill these fields based on what is exposed in AVPacketSideData.
Additionally, in the same commit, don't write these fields to
the output unless analyze_frames is enabled. Finally, fix the
FATE test refs accordingly and update the docs.

If running tests with "make -j<N> fate", the execution will stop
after the first failing test. To get an overview of the whole
test suite, one rather would run "make -k -j<N> fate", which then
again buries the results about what tests actually failed further
up in the console log.
Add a target so one can run "make fate-list-failing", to see a list
of all tests that failed the last time they were executed.
Also add a companion target "fate-clear-reports" which removes all
the old test reports. (When executing a subset of tests, the report
files of all tests that aren't executed stay untouched. This also
allows getting rid of reports for tests that no longer are present
in the testsuite.)

The existing av_csp_trc_func_from_id() mostly implements the OETF, except for
PQ. As such, we are currently missing a precise definition of an ITU-R EOTF.
Introduce the new functions av_csp_itu_eotf() and av_csp_itu_eotf_inv(), to fill
this void. Note that this is not possible in all cases, e.g. AVCOL_TRC_LOG which
has no corresponding EOTF definition in any ITU-R standard.
Note that we cannot implement the proper HLG and SMPTE 428 OOTFs without access
to all three color channels, because they are not independent per channel. As a
result, we need to define them on double[3] instead of double (*func)(double).
Makes it easier to immediately see if the code examples given in the
style documentation are good or bad examples, making it harder to
accidentally confuse a bad example for a good one.
Given the frequency that new developers, myself included, get the
code style wrong, it is useful to add some examples to clarify how
things should be done.
As part of a larger, ongoing effort to modernize and partially rewrite
libswscale, it was decided and generally agreed upon to introduce a new
public API for libswscale. This API is designed to be less stateful, more
explicitly defined, and considerably easier to use than the existing one.
Most of the API work has been already accomplished in the previous commits,
this commit merely introduces the ability to use sws_scale_frame()
dynamically, without prior sws_init_context() calls. Instead, the new API
takes frame properties from the frames themselves, and the implementation is
based on the new SwsGraph API, which we simply reinitialize as needed.
This high-level wrapper also recreates the logic that used to live inside
vf_scale for scaling interlaced frames, enabling it to be reused more easily
by end users.
Finally, this function is designed to simply copy refs directly when nothing
needs to be done, substantially improving throughput of the noop fast path.

Group them into an enum rather than random #defines, and document their
behavior a bit more obviously.
Of particular note, I discovered that SWS_DIRECT_BGR is not referenced
anywhere else in the code base. As such, I have moved it to the deprecated
section, alongside SWS_ERROR_DIFFUSION.

Following in the footsteps of the work in the previous commit, it's now
relatively straightforward to expose the options struct publicly as
SwsContext. This is a step towards making this more user friendly, as
well as following API conventions established elsewhere.

This avoids unpleasant surprises to av_frame_get_buffer callers
that explicitly specified 64-byte alignment and didn't get
AVFrame.data pointers that are 64-byte aligned.
For example, see https://github.com/sekrit-twc/zimg/issues/212
Although the zscale issue has already been resolved by other means
it would still be prudent to improve the behavior of av_frame_get_buffer
to fix any unknown and future instances of similar issues.
