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

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).

The "auto" mode serves no functional purpose except for logging
a message and setting the value to 1. The documentation clearly
explains what the option is for.

Menu 0 is the VIDEO_TS root menu, which does not appear to be used
commonly for menu segments. Instead, default to the menu of VTS 1.

Menus are generally segmented by cell, so use them as the
marker delimiters. Requires preindex option to be enabled.

The default "auto" mode is effectively useless; the reasonable
default use case is to use the first PG (segment) of the
selected PGC for both menus and standard titles. Just
default the value to 1, since the option is irrelevant
unless -pgc is also set.
Note that this should not break users using this advanced option.
The "auto" mode errored and asked for a PG number regardless
for non-menus, and for menus the mode simply defaulted to 1.

This extends the syntax for specifying input streams in -map and complex
filtergraph labels, to allow selecting a view by view ID, index, or
position. The corresponding decoder is then set up to decode the
appropriate view and send frames for that view to the correct
filtergraph input(s).
Deprecate the option 'draw_bars' in favor of the new option 'signal_loss_action',
which controls the behavior when the input signal is not available
(including the behavior previously available through draw_bars).
The default behavior remains unchanged to be backwards compatible.
The new option is more flexible for extending now and in the future.
The new value 'repeat' repeats the last video frame.
This is useful for very short dropouts and was not available before.

This replaces the myriad of existing lists in AVCodec by a unified API
call, allowing us to (ultimately) trim down the sizeof(AVCodec) quite
substantially, while also making this more trivially extensible.
In addition to the already covered lists, add two new entries for color
space and color range, mirroring the newly added negotiable fields in
libavfilter.
Once the deprecation period passes for the existing public fields, the
rough plan is to move the commonly used fields (such as
pix_fmt/sample_fmt) into FFCodec, possibly as a union of audio and video
configuration types, and then implement the rarely used fields with
custom callbacks.
Previously one could only replace the entire array with a new one
deserialized from a string. The new API allows inserting, replacing, and
removing arbitrary element ranges.
Currently, this just functions as a more principled and user-friendly
replacement for the (undocumented and hard to use) *_chr_pos fields.
However, the goal is to automatically infer these values from the input
frames' chroma location, and deprecate the manual use of *_chr_pos
altogether. (Indeed, my plans for an swscale replacement will most
likely also end up limiting the set of legal chroma locations to those
permissible by AVFrame properties)

The B extension was finally ratified in May 2024, encompassing:
- Zba (addresses),
- Zbb (basics) and
- Zbs (single bits).
It does not include Zbc (base-2 polynomials).
