Wenbin Chen f4e0664fd1 libavfi/dnn: add LibTorch as one of DNN backend
PyTorch is an open source machine learning framework that accelerates
the path from research prototyping to production deployment. Official
website: https://pytorch.org/. We call the C++ library of PyTorch as
LibTorch, the same below.

To build FFmpeg with LibTorch, please take following steps as
1. download LibTorch C++ library in
please select C++/Java for language, and other options as your need.
Please download cxx11 ABI version:
2. unzip the file to your own dir, with command
unzip libtorch-shared-with-deps-latest.zip -d your_dir
3. export libtorch_root/libtorch/include and
libtorch_root/libtorch/include/torch/csrc/api/include to $PATH
export libtorch_root/libtorch/lib/ to $LD_LIBRARY_PATH
4. config FFmpeg with ../configure --enable-libtorch \
 --extra-cflag=-I/libtorch_root/libtorch/include \
 --extra-cflag=-I/libtorch_root/libtorch/include/torch/csrc/api/include \
5. make

To run FFmpeg DNN inference with LibTorch backend:
./ffmpeg -i input.jpg -vf \
dnn_processing=dnn_backend=torch:model=LibTorch_model.pt -y output.jpg

The LibTorch_model.pt can be generated by Python with torch.jit.script()
api. https://pytorch.org/tutorials/advanced/cpp_export.html. This is
pytorch official guide about how to convert and load torchscript model.
Please note, torch.jit.trace() is not recommanded, since it does
not support ambiguous input size.

Andreas Rheinhardt b800327f4c avformat/avformat: Add FFInputFormat, hide internals of AVInputFormat
This commit does for AVInputFormat what commit
59c9dc82f4 did for AVOutputFormat:
It adds a new type FFInputFormat, moves all the internals
of AVInputFormat to it and adds a now reduced AVInputFormat
as first member.

This does not affect/improve extensibility of both public
or private fields for demuxers (it is still a mess due to lavd).

This is possible since 50f34172e0
(which removed the last usage of an internal field of AVInputFormat
in fftools).

(Hint: tools/probetest.c accesses the internals of FFInputFormat
as well, but given that it is a testing tool this is not considered
a problem.)

Andreas Rheinhardt 25e0e087c4 configure: Disable linker warnings for common symbols
Common symbols are not part of ISO-C and therefore not used
by FFmpeg at all. Yet linker warnings to ensure it stays
that way are nevertheless wrong, because the existence of
common symbols does not imply that there is a bug in our code.

More precisely, Clang's ASAN implementation uses a common symbol
___asan_globals_registered when used on Elf targets with
the -fsanitize-address-globals-dead-stripping option;
said option is the default since Clang 17 [1].
This leads to 1883 warnings about ___asan_globals_registered
when linking here.
(Even without that option there were warnings like
_ZN14__interception10real_vforkE being overridden.)

Said warning is also unnecessary: The proper way to ensure
that our code is free of common symbols is to let the compiler
enforce this. But this is already the default since GCC 10
and Clang 11, so there is no risk of introducing our own
common symbols.

configure: fix compilation with glslang 14
The configure check already had fallback for the previous version
of glslang, which had different requirements for flags.
This commit simply moves the flags needed for glslang 13 to the
fallback, while first trying to use new flags for glslang 14.

This drops support for ~3 year old glslang versions, which
I'm not sure had the complete C API we're using anyway.

Martin Storsjö de9bc4f205 configure: Don't pass -mfp16-format to MSVC on ARM
The check for this option does succeed - MSVC accepts the option,
but prints a warning about it being unknown and ignored, for
each compiled object file:

    cl : Command line warning D9002 : ignoring unknown option '-mfp16-format=ieee'

The configure script only attempts to add this option on ARM,
therefore this warning isn't seen by the majority of people
building with MSVC.

Making this option into a no-op probably isn't entirely right,
but on the other hand, we don't want to litter the code that
checks for support for the option with compiler specific
conditions either.

Kalev Lember b391fdbf1a lavc/libopenh264: Drop openh264 runtime version checks
With the way the runtime checks are currently set up, every single
openh264 release, no matter how minor, is considered an ABI break and
requires ffmpeg recompilation. This is unnecessarily strict because it
doesn't allow downstream distributions to ship any openh264 bug fix
version updates without breaking ffmpeg's openh264 support.

Years ago, at the time when ffmpeg's openh264 support was merged,
openh264 releases were done without a versioned soname (the library was
just libopenh264.so, unversioned). Since then, starting with version
1.3.0, openh264 has started using versioned sonames and the intent has
been to bump the soname every time there's a new release with an ABI

This patch drops the exact version check and instead adds a minimum
requirement on 1.3.0 to the configure script.

Dai, Jianhui J c9fe9fb863 avcodec/cbs_vp8: Add support for VP8 codec bitstream
This commit adds support for VP8 bitstream read methods to the cbs
codec. This enables the trace_headers bitstream filter to support VP8,
in addition to AV1, H.264, H.265, and VP9. This can be useful for
debugging VP8 stream issues.

The CBS VP8 implements a simple VP8 boolean decoder using GetBitContext
to read the bitstream.

Only the read methods `read_unit` and `split_fragment` are implemented.

Martin Storsjö 2c3d2a0245 configure: Improve aarch64 feature detection on older, broken Clang versions
Clang versions before 17 (Xcode versions up to and including 15.0)
had a very annoying bug in its behaviour of the ".arch" directive
in assembly. If the directive only contained a level, such as
".arch armv8.2-a", it did validate the name of the level, but it
didn't apply the level to what instructions are allowed. The level
was applied if the directive contained an extra feature enabled,
such as ".arch armv8.2-a+crc" though. It was also applied on the
next ".arch_extension" directive.

This bug, combined with the fact that the same versions of Clang
didn't support the dotprod/i8mm extension names in either
".arch <level>+<feature>" or in ".arch_extension", could lead to
unexepcted build failures.

As the dotprod/i8mm extensions couldn't be enabled dynamically
via the ".arch_extension" directive, someone building ffmpeg could
try to enable them by configuring their build with

During configure, we test for support for the i8mm instructions
like this:

    # Built with -march=armv8.6-a
    .arch armv8.2-a             # Has no visible effect here
    #.arch_extension i8mm       # Omitted as the extension name isn't known
    usdot v0.4s, v0.16b, v0.16b
    # Successfully assembled as armv8.6-a is the effective level,
    # and i8mm is enabled implicitly in armv8.6-a.

Thus, we would enable assembling those instructions. However if
we later check for another extension, such as sve (which those
versions of Clang actually do support), we can later run into the
following situation when building actual code:

    # Built with -march=armv8.6-a
    .arch armv8.2-a             # Has no visible effect here
    #.arch_extension i8mm       # Omitted as the extension name isn't known
    .arch_extension sve         # Included as "sve" is as supported extension name
    # .arch_extension effectively activates the previous .arch directive,
    # so the effective level is armv8.2-a+sve now.
    usdot v0.4s, v0.16b, v0.16b
    # Fails to build the instructions that require i8mm. Despite the
    # configure check, the unrelated ".arch_extension sve" directive
    # breaks the functionality of the i8mm feature.

This patch avoids this situation:
- By adding a dummy feature such as "+crc" on the .arch directive
  (if supported), we make sure that it does get applied immediately,
  avoiding it taking effect spuriously at a later unrelated
  ".arch_extension" directive.
- By checking for higher arch levels such as armv8.4-a and armv8.6-a,
  we can assemble the dotprod and i8mm extensions without the user
  needing to pass -march=armv8.6-a. This allows using the dotprod/i8mm
  codepaths via runtime detection while keeping the binary runnable
  on older versions. I.e. this enables the i8mm codepaths on Apple M2
  machines while built with Xcode's Clang.

TL;DR: Enable the I8MM extensions for Apple M2 without the user needing
to do a custom configuration; avoid potential build breakage if a user
does such a custom configuration.

Once Xcode versions that have these issues fixed are prevalent, we
can consider reverting this change.

TADANO Tokumei 21bfadd9b4 lavc/libaribcaption: add MSZ character related options
This patch adds two MSZ (Middle Size; half width) character
related options, mapping against newly added upstream

* `replace_msz_japanese`, which was introduced in version 1.0.1
  of libaribcaption.
* `replace_msz_glyph`, which was introduced in version 1.1.0
  of libaribcaption.

The latter option improves bitmap type rendering if specified
fonts contain half-width glyphs (e.g., BIZ UDGothic), even
if both ASCII and Japanese MSZ replacement options are set
to false.

As these options require newer versions of libaribcaption, the
configure requirement has been bumped accordingly.

Rémi Denis-Courmont f032234953 aarch64: remove VFP feature check
This is not actually used for anything. The configure check causes the
CPU feature flag to be set, but nothing consumes it at all.

While AArch64 does have VFP, it is only used for the scalar C code.
Conversely, it is still possible to disable VFP, by changing the
C compiler flags as before (though that only makes sense for an
hypothetical non-standard Armv8 platform without VFP).

Note that this retains the "vfp" option flag, for backward
compatibility and on the very remote but theoretically possible chance
that FFmpeg actually makes use of it in the future.

AV_CPU_FLAG_VFP is retained as it is actually used by AArch32.
