4d9c0b3efa configure: Add (h264|hevc)_sei subsystems
Currently, several components select atsc_a53, despite
not using anything from it themselves. They only select
it because parsing SEI messages adds an indirect dependency.
But using direct dependencies is more natural, so add
dedicated subsystems for them.

It already allows to remove a superfluous dependency of
the HEVC QSV encoder on hevc_sei and atsc_a53.

Adding new subsystems only becomes effective after a reconfiguration.
In order to force this, some needed headers (which are only included
implicitly before this commit) were included explicitly in
libavformat/allformats.c.

efe2b63c89 doc/examples: Add qsv_transcode example
Add qsv_transcode example which shows how to use qsv to do hardware
accelerated transcoding, also show how to dynamically set encoding
parameters.

examples:
Normal usage:
qsv_transcode input.mp4 h264_qsv output.mp4 "g 60"

Dynamic setting usage:
qsv_transcode input.mp4 hevc_qsv output.mp4 "g 60 asyne_depth 1"
100 "g 120"
This command initializes codec with gop_size 60 and change it to

496b3c6987 avcodec/vc1dec: Remove VC-1 decoders->H.263 decoder dependency
The only thing from the H.263 decoder that is reachable
by the VC-1 decoder is ff_h263_decode_init(); but it does
not even use all of it; e.g. h263dsp is unused and so are
the VLCs initialized in ff_h263_decode_init() (they amount
to about 77KB which are now no longer touched).

Notice that one could also call ff_idctdsp_init()
directly instead of ff_mpv_idct_init(); one could even
do so in ff_vc1_init_common().

cbe6ef1031 avcodec/vc1dec: Split VC-1 decoders from msmpeg4
The only msmpeg4 code that is ever executed by the VC-1 based
decoders is ff_msmpeg4_decode_init() and what is directly
reachable from it. This is:
a) A call to av_image_check_size(), then ff_h263_decode_init(),
b) followed by setting [yc]_dc_scale_table and initializing
scantable/permutations.
c) Afterwards, some static tables are initialized.
d) Finally, slice_height is set.

The replacement for ff_msmpeg4_decode_init() performs a)
just like now; it also sets [yc]_dc_scale_table,
but it only initializes inter_scantable and intra_scantable
and not permutated_intra_[hv]_scantable: The latter are only
used inside decode_mb callbacks which are only called
in ff_h263_decode_frame() which is unused for VC-1.*

The static tables initialized in c) are not used at all by
VC-1 (the ones that are used have been factored out in
previous commits); this avoids touching 327KiB of .bss.

slice_height is also not used by the VC-1 decoder (setting
it in ff_msmpeg4_decode_init() is probably redundant after
b34397b4cd).

*: It follows from this that the VC-1 decoder is not really
based upon the H.263 decoder either; changing this will
be done in a future commit.

5c288a44ad avcodec/nvenc: add AV1 encoding support
The encoder seems to be trading blows with hevc_nvenc.
In terms of quality at low bitrate cbr settings, it seems to
outperform it even. It produces fewer artifacts and the ones it
does produce are less jarring to my perception.

At higher bitrates I had a hard time finding differences between
the two encoders in terms of subjective visual quality.

Using the 'slow' preset, av1_nvenc outperformed hevc_nvenc in terms
of encoding speed by 75% to 100% while performing above tests.

Needless to say, it always massively outperformed h264_nvenc in terms
of quality for a given bitrate, while also being slightly faster.

ef285d59ac configure, avcodec/Makefile: Remove obsolete mpegvideo dependencies
As long as ff_mpeg12_common_init() existed in mpeg12.c,
it added a dependency of mpeg12.o on mpegvideodata.o
(which provides ff_mpeg2_dc_scale_table, which is used
in ff_mpeg12_common_init()). mpegvideodata.o is normally
provided by the mpegvideo subsystem and therefore several
codecs and the MPEG-1/2 parser added a configure dependency
on said subsystem (additionally, the eatqi decoder just
added a Makefile dependency on mpegvideodata.o).

Given that ff_mpeg12_common_init() is no more, these dependencies
can be removed.

b92e14147f avcodec: add a bsf to reorder DTS into PTS
Starting with an h264 implementation. Can be extended to support other codecs.

A few caveats:
- OpenGOP streams are currently not supported. The firt packet must be an IDR
  frame.
- In some streams, a few frames at the end may not get a reordered PTS when
  they reference frames past EOS. The code added to derive timestamps from
  previous frames needs to extended.

ef2c2a2220 avutil/half2float: use native _Float16 if available
_Float16 support was available on arm/aarch64 for a while, and with gcc
12 was enabled on x86 as long as SSE2 is supported.

If the target arch supports f16c, gcc emits fairly efficient assembly,
taking advantage of it. This is the case on x86-64-v3 or higher.
Same goes on arm, which has native float16 support.
On x86, without f16c, it emulates it in software using sse2 instructions.

This has shown to perform rather poorly:

frame=50074 fps=848 q=-0.0 size=N/A time=00:33:22.96 bitrate=N/A speed=33.9x

_Float16 f16c accelerated (Zen2, --cpu=znver2):
frame=50636 fps=1965 q=-0.0 Lsize=N/A time=00:33:45.40 bitrate=N/A speed=78.6x

classic half2float full software implementation:
frame=49926 fps=1605 q=-0.0 Lsize=N/A time=00:33:17.00 bitrate=N/A speed=64.2x

Hence an additional check was introduced, that only enables use of
_Float16 on x86 if f16c is being utilized.

On aarch64, a similar uplift in performance is seen:

RPi4 half2float full software implementation:
frame= 6088 fps=126 q=-0.0 Lsize=N/A time=00:04:03.48 bitrate=N/A speed=5.06x

RPi4 _Float16:
frame= 6103 fps=158 q=-0.0 Lsize=N/A time=00:04:04.08 bitrate=N/A speed=6.32x

Since arm/aarch64 always natively support 16 bit floats, it can always
be considered fast there.

I'm not aware of any additional platforms that currently support
_Float16. And if there are, they should be considered non-fast until
proven fast.

3e61b7dd7f qsv: remove mfx/ prefix from mfx headers
The following Cflags has been added to libmfx.pc, so mfx/ prefix is no
longer needed when including mfx headers in FFmpeg.
   Cflags: -I${includedir} -I${includedir}/mfx

Some old versions of libmfx have the following Cflags in libmfx.pc
   Cflags: -I${includedir}

We may add -I${includedir}/mfx to CFLAGS when running 'configure
--enable-libmfx' for old versions of libmfx, if so, mfx headers without
mfx/ prefix can be included too.

If libmfx comes without pkg-config support, we may do a small change to
the settings of the environment(e.g. set -I/opt/intel/mediasdk/include/mfx
instead of -I/opt/intel/mediasdk/include to CFLAGS), then the build can
find the mfx headers without mfx/ prefix

After applying this change, we won't need to change #include for mfx
headers when mfx headers are installed under a new directory.

This is in preparation for oneVPL support (mfx headers in oneVPL are
installed under vpl directory)

cc5844da98 libavutil: Add wchartoutf8(), wchartoansi(), utf8toansi(), getenv_utf8(), freeenv_utf8() and getenv_dup()
wchartoutf8() converts strings returned by WinAPI into UTF-8,
which is FFmpeg's preffered encoding.

Some external dependencies, such as AviSynth, are still
not Unicode-enabled. utf8toansi() converts UTF-8 strings
into ANSI in two steps: UTF-8 -> wchar_t -> ANSI.
wchartoansi() is responsible for the second step of the conversion.
Conversion in just one step is not supported by WinAPI.

Since these character converting functions allocate the buffer
of necessary size, they also facilitate the removal of MAX_PATH limit
in places where fixed-size ANSI/WCHAR strings were used
as filename buffers.

On Windows, getenv_utf8() wraps _wgetenv() converting its input from
and its output to UTF-8. Strings returned by getenv_utf8()
must be freed by freeenv_utf8().

On all other platforms getenv_utf8() is a wrapper around getenv(),
and freeenv_utf8() is a no-op.

The value returned by plain getenv() cannot be modified;
av_strdup() is usually used when modifications are required.
However, on Windows, av_strdup() after getenv_utf8() leads to
unnecessary allocation. getenv_dup() is introduced to avoid
such an allocation. Value returned by getenv_dup() must be freed
by av_free().

Because of cleanup complexities, in places that only test the existence
of an environment variable or compare its value with a string
consisting entirely of ASCII characters, the use of plain getenv()
is still preferred. (libavutil/log.c check_color_terminal()
is an example of such a place.)

Plain getenv() is also preffered in UNIX-only code,
such as bktr.c, fbdev_common.c, oss.c in libavdevice
or af_ladspa.c in libavfilter.

dd5a0302d5 avcodec/libx264: Set min build version to 158 for msvc
Was "[PATCH] libx264: Do not explicitly set X264_API_IMPORTS"

Setting X264_API_IMPORTS only affects msvc builds and it breaks
linking to static builds (although is required for shared builds).
This flag is set by x264 in its pkgconfig as required since build
158 (a615f027ed172e2dd5380e736d487aa858a0c4ff) from July 2019.
So this patch updates configure to require a newer x264 build that
correctly sets the imports flag.

The min version requirement of 158 is applied for msvc builds only.

This is also removing the check for 'libx264 without pkg-config'
which was left for compatibility reasons about 7 years ago when
the pkg-config check was introduced by commit
e06263ef1e.

etc).

The files generated by this muxer has been verified to be valid

This also gives the user more flexibility to e.g. first attach an ICC

b9a25963f7 lavfi: add ICC profile support via lcms2
This introduces an optional dependency on lcms2 into FFmpeg. lcms2 is a
widely used library for ICC profile handling, which apart from being
used in almost all major image processing programs and video players,
has also been deployed in browsers. As such, it's both widely available
and well-tested.

Add a few helpers to cover our major use cases. This commit merely
introduces the helpers (and configure check), even though nothing uses
them yet.

It's worth pointing out that the reason the cmsToneCurves for each
AVCOL_TRC are cached inside the context, is because constructing a
cmsToneCurve requires evaluating the curve at 4096 (by default) grid
points and constructing a LUT. So, we ideally only want to do this once
per curve. This matters for e.g. ff_icc_profile_detect_transfer, which
essentially compares a profile against all of these generated LUTs.
Re-generating the LUTs for every iteration would be unnecessarily
wasteful.

The same consideration does not apply to e.g. cmsCreate*Profile, which
is a very lightweight operation just involving struct allocation and
setting a few pointers.

The cutoff value of 0.01 was determined by experimentation. The lowest
"false positive" delta I saw in practice was 0.13, and the largest
"false negative" delta was 0.0008. So a value of 0.01 sits comfortaby
almost exactly in the middle.

f889837e00 avformat: Add IPFS protocol support.
This patch adds support for:
- ffplay ipfs://<cid>
- ffplay ipns://<cid>

IPFS data can be played from so called "ipfs gateways".
A gateway is essentially a webserver that gives access to the
distributed IPFS network.

This protocol support (ipfs and ipns) therefore translates
ipfs:// and ipns:// to a http:// url. This resulting url is
then handled by the http protocol. It could also be https
depending on the gateway provided.

To use this protocol, a gateway must be provided.
If you do nothing it will try to find it in your
$HOME/.ipfs/gateway file. The ways to set it manually are:
1. Define a -gateway <url> to the gateway.
2. Define $IPFS_GATEWAY with the full http link to the gateway.
3. Define $IPFS_PATH and point it to the IPFS data path.
4. Have IPFS running in your local user folder (under $HOME/.ipfs).

dd8a55cb3e avcodec/zlib_wrapper: Add wrappers for zlib inflateInit, inflateEnd
It is not documented to be safe to call inflateEnd() on a z_stream
that has never been successfully been initialized by inflateInit(),
but just zeroed. It just happens to work and several codecs rely
on this (they have FF_CODEC_CAP_INIT_CLEANUP set and even call
inflateEnd() when inflateInit() failed or has never been called).
To avoid this, other codecs recorded whether their zstream has been
initialized successfully or not.

This commit adds wrappers for inflateInit() and inflateEnd() that
do what these other codecs do; furthermore, they also take care of
properly setting up the zstream before inflateInit() and emit
an error message in case of error.

bc5ccea3b9 configure: move ranlib -D test after setting defaults
In Gentoo and ChromeOS we want to allow pure LLVM builds without
using GNU tools, so we block any unwanted mixed GNU/LLVM usages
(GNU tools are still kept around in our chroots for projects
like glibc which cannot yet be built otherwise).

The default ${cross_prefix}${ranlib_default} points to GNU and
fails, so move the test a bit later - after the defaults are
set and the proper values get overriden - such that ffmpeg
configure calls the llvm-ranlib we desire. [1]

It's worth documenting that this relies on the dovi configuration record

fe04033739 lavc: Implement Dolby Vision RPU parsing
Based on a mixture of guesswork, partial documentation in patents, and
reverse engineering of real-world samples. Confirmed working for all the
samples I've thrown at it.

Contains some annoying machinery to persist these values in between
frames, which is needed in theory even though I've never actually seen a
sample that relies on it in practice. May or may not work.

Since the distinction matters greatly for parsing the color matrix
values, this includes a small helper function to guess the right profile
from the RPU itself in case the user has forgotten to forward the dovi
configuration record to the decoder. (Which in practice, only ffmpeg.c
and ffplay do..)

Notable omissions / deviations:
- CRC32 verification. This is based on the MPEG2 CRC32 type, which is
  similar to IEEE CRC32 but apparently different in subtle enough ways
  that I could not get it to pass verification no matter what parameters
  I fed to av_crc. It's possible the code needs some changes.
- Linear interpolation support. Nothing documents this (beyond its
  existence) and no samples use it, so impossible to implement.
- All of the extension metadata blocks, but these contain values that
  seem largely congruent with ST2094, HDR10, or other existing forms of
  side data, so I will defer parsing/attaching them to a future commit.
- The patent describes a mechanism for predicting coefficients from
  previous RPUs, but the bit for the flag whether to use the
  prediction deltas or signal entirely new coefficients does not seem to
  be present in actual RPUs, so we ignore this subsystem entirely.
- In the patent's spec, the NLQ subsystem also loops over
  num_nlq_pivots, but even in the patent the number is hard-coded to one
  iteration rather than signalled. So we only store one set of coefs.

20b0d24c2f Makefile: Redo duplicating object files in shared builds
In case of shared builds, some object files containing tables
are currently duplicated into other libraries: log2_tab.c,
golomb.c, reverse.c. The check for whether this is duplicated
is simply whether CONFIG_SHARED is true. Yet this is crude:
E.g. libavdevice includes reverse.c for shared builds, but only
needs it for the decklink input device, which given that decklink
is not enabled by default will be unused in most libavdevice.so.

This commit changes this by making it more explicit about what
to duplicate from other libraries. To do this, two new Makefile
variables were added: SHLIBOBJS and STLIBOBJS. SHLIBOBJS contains
the objects that are duplicated from other libraries in case of
shared builds; STLIBOBJS contains stuff that a library has to
provide for other libraries in case of static builds. These new
variables provide a way to enable/disable with a finer granularity
than just whether shared builds are enabled or not. E.g. lavd's
Makefile now contains: SHLIBOBJS-$(CONFIG_DECKLINK_INDEV) += reverse.o

Another example is provided by the golomb tables. These are provided
by lavc for static builds, even if one uses a build configuration
that makes only lavf use them. Therefore lavc's Makefile contains
STLIBOBJS-$(CONFIG_MXF_MUXER) += golomb.o, whereas lavf's Makefile
has a corresponding SHLIBOBJS-$(CONFIG_MXF_MUXER) += golomb_tab.o.
E.g. in case the MXF muxer is the only component needing these tables
only libavformat.so will contain them for shared builds; currently
libavcodec.so does so, too.
(There is currently a CONFIG_EXTRA group for golomb. But actually
one would need two groups (golomb_avcodec and golomb_avformat) in
order to know when and where to include these tables. Therefore
this commit uses a Makefile-based approach for this and stops
using these groups for the users in libavformat.)

4ac869ca2a avfilter: add vf_yadif_videotoolbox
deinterlaces CVPixelBuffers, i.e. AV_PIX_FMT_VIDEOTOOLBOX frames

for example, an interlaced mpeg2 video can be decoded by avcodec,
uploaded into a CVPixelBuffer, deinterlaced by Metal, and then
encoded to h264 by VideoToolbox as follows:

    ffmpeg \
           -init_hw_device videotoolbox \
           -i interlaced.ts \
           -vf hwupload,yadif_videotoolbox \
           -c:v h264_videotoolbox \
           -b:v 2000k \
           -c:a copy \
           -y progressive.ts

(note that uploading AVFrame into CVPixelBuffer via hwupload
 requires 504c60660d)

5317a6366f vf_libplacebo: switch to newer libplacebo helpers
Support for mapping/unmapping hardware frames has been added into
libplacebo itself, so we can scrap this code in favor of using the new
functions. This has the additional benefit of being forwards-compatible
as support for more complicated frame-related state management is added
to libplacebo (e.g. mapping dolby vision metadata).

It's worth pointing out that, technically, this would also allow
`vf_libplacebo` to accept, practically unmodified, other frame types
(e.g. vaapi or drm), or even software input formats. (Although we still
need a vulkan *device* to be available)

To keep things simple, though, retain the current restriction to vulkan
frames. It's possible we could rethink this in a future commit, but for
now I don't want to introduce any more potentially breaking changes.

51e03409d7 lavfi: add a libplacebo filter
This filter conceptually maps the libplacebo `pl_renderer` API into
libavfilter, which is a high-level image rendering API designed to work
with an RGB pipeline internally. As such, there's no way to avoid e.g.
chroma interpolation with this filter, although new versions of
libplacebo support outputting back to subsampled YCbCr after processing
is done.

That being said, `pl_renderer` supports automatic integration of the
majority of libplacebo's shaders, ranging from debanding to tone
mapping, and also supports loading custom mpv-style user shaders, making
this API a natural candidate for getting a lot of functionality out of
relatively little code.

In the future, I may approach this problem either by rewriting this
filter to also support a non-renderer codepath, or by upgrading
libplacebo's renderer to support a full YCbCr pipeline.

This unfortunately requires a very new version of libplacebo (unreleased
at time of writing) for timeline semaphore support. But the amount of
boilerplate needed to hack in backwards compatibility would have been
very unreasonable.

cb8dc600d2 configure: arm: Don't add -march= to the compiler if no preference was passed
If no --cpu= option was passed to configure, we detect what the
compiler defaults to. This detected value was then fed back to the
rest of the configure logic, as if it was an explicit choice.

This breaks on Ubuntu 21.10 with GCC 11.1.

Since GCC 8, it's possible to add configure extra features via the
-march option, like e.g. -march=armv7-a+neon. If the -mfpu= option
is configured to default to 'auto', the fpu setting gets taken
from the -march option.

GCC 11.1 in Ubuntu seems to be configured to use -mfpu=auto. This
has the effect of breaking any compilation command that specifies
-march=armv7-a, because the driver implicitly also adds -mfloat-abi=hard,
and that combination results in this error:

    cc1: error: ‘-mfloat-abi=hard’: selected processor lacks an FPU

One can compile successfully by passing e.g. -march=armv7-a+fp.

Therefore, restructure configure. If no specific preference was set
(and the 'cpu' configure variable was set as the output of
probe_arm_arch), the value we tried to set via -march= was the same
value that we just tried to detect as the compiler default.

So instead, just try to detect what the compiler defaults to, with
to allow setting other configure settings (such as 'fast_unaligned'),
but don't try to spell out the compiler's default via the -march flag.

can contain spaces).

It's currently unclear whether this behaviour will stay or if it
is going to be reverted in the future, see discussion at [1]. Just
to be safe, avoid using the --preprocessor argument. Don't redeclare
the full preprocessing command, but just add the $(CC_DEPFLAGS) options.
