    avcodec/pcm_tablegen: Fix hardcoded-tables if alaw,mulaw,vidc codecs disabled
Since ae448e00afb43d7f72dfa9c82a4c45994e4fea6a the various
tableinit functions are not compiled unconditionally any more,
so that pcm_tablegen.c (which creates the hardcoded tables)
needs to be updated.

    avcodec/dvdsubdec: Don't return value != 0 on init success
Currently, any nonnegative return value from an init function
is just treated as success and otherwise ignored; while it is
not explicitly forbidden to return something else than 0 (there
is no documentation whatsoever), the assumption is that
they return zero on success. So change dvdsubdec.c accordingly.

Also change dvdsub_parse_extradata() to return zero on success.

Right now, CFLAGS like -std=c17 leak onto the C++ compilers commandline,
leading to tons of warnings and even some errors.

Undefining __STRICT_ANSI__ causes strong warnings from the stdlib

MinGWs ANSI stdio is quite slow, and when using UCRT, its extra features
are not needed.
The only troublesome part with ucrt printf is that is disagrees about
the size of "long double", but FFmpeg does not use that anywhere, let
alone prints it.

    avcodec/rkmppdec: fix input queue overflow
The strategy to count free slots isn't reliable. The value of
INPUT_MAX_PACKETS is a hardcoded value, and MPP_DEC_GET_STREAM_COUNT
doesn't always work as expected. When freeslots is nonzero, the mpp
decoder still returns MPP_ERR_BUFFER_FULL. Before this patch, all
packets are dropped once went into MPP_ERR_BUFFER_FULL state.

Don't drop packet and return error in MPP_ERR_BUFFER_FULL state.
Receive frame to allow the decoder's state machine to resume.

    avfilter/vsrc_gfxcapture: switch to std::thread
Combining C++ with our w32pthreads does not work out.
The C++ standard lib headers might include pthread.h, which will then
define clashing types with our w32pthread header.

To solve this, switch to using C++ native std::thread.

    avformat/whip: enable RTCP NACK for whip
Refer to RFC 4585 4.2,
Add SDP "a=rtcp-fb" so the peer can request rtx
through sending NACKs.

Add basic parsing for NACK packet.
Decrypt into a newly allocated buffer (do not
overwrite whip->buf) so multiple NACKs in a
bundled packet can be parsed in a loop while
keeping whip->buf available for sending rtx

Broken or wrong NACk are logged and skipped.

    vf_colorspace: Add an option to clamp trc LUT output
Add a new flag to the vf_colorspace filter which provides the user an
option to clamp the linear and delinear transfer characteristics LUT
values to the [0, 1] represented range. This helps constrain the
potential value range when converting between colorspaces.

Certain colors when going through the conversion can result in out of
gamut colors after the rotation. The colorspace filter allows that with
the extended range. The added clamping just keeps the colors within the
[0, 1) range rather than using that extended range. I'm not enough of a
color scientist to say which is correct, but there are certain
situations where we would prefer to keep the colors in gamut.

The example I have is:

A solid color image of 8-bit YUV: Y=157, U=164, V=98.

Specify the input as:

Input range: MPEG
In color matrix: BT470BG
In color primaries: BT470M
In color transfer characteristics: Gamma 28

Output as:
Out color range: JPEG
Out color matrix: BT.709
Out color primaries: BT.709
Out color transfer characteristics: BT.709

During the calculation you get:

Input YUV:                             y=157,      u=164,      v-98
Post-yuv2rgb BT.470BG:                 r=0.456055, g=0.684152, b=0.928606
Post-apply gamma28 linear LUT:         r=0.110979, g=0.345494, b=0.812709
Post-color rotation BT.470M to BT.709: r=-0.04161, g=0.384626, b=0.852400
Post-apply Rec.709 delinear LUT:       r=-0.16382, g=0.615932, b=0.923793
Post-rgb2yuv Rec.709 matrix:           y=120,      u=190,      v=25

Where with this change, the delinear LUT output would be clamped to 0,
so the result would be:
r=0.000000, g=0.612390, b=0.918807 and a final output of
y=129, u=185, v=46

As for the long and av_clip64, this was just because lrint returned a
long, so I left it as that and then used av_clip64 to the [0,1) range to
avoid overflow. But re-reading, it looks like av_clip_int16 would
downcast that long to int anyway so the possibility of overflow already
existed there. I've put it back to int just to match the existing
behavior.

    configure: also initialize objcflags_filter early
Fixes an issue uncovered since 0ce413af9cc8040095a6b714600d6a8dceaca514
where flags were properly separated but without the objcflags_filter
being initialized, if add_objcflags is called early as part of
add_allcflags, it would lead to the append() function using an empty
filter and trying to call the flag instead, leading to errors like:

./configure: line 976: -fsanitize=address: command not found

Otherwise it might be > buf_ptr in which case ffio_get_checksum()

which would be converted to something very big when converted
to unsigned for the update_checksum callback).

    avformat/oggdec: Don't skip over data whose checksum is used
The behavior of the ffio_*_checksum feature is not well defined
when using avio_skip(). The code in oggdec.c relied on the skipped
data (four bytes) to be checksummed, which is mostly true
because short_seek_threshold is 32768 by default, so that
avio_seek() will normally read data instead of calling the
underlying seek function. Yet this has two problems:

a) It relies on implementation details of avio_seek().
b) There is an exception, namely if the AVIO_FLAG_DIRECT is set.
In this case the underlying seek function (if set) is always
called and the data is skipped, leading to CRC errors.

So don't skip the data.

    avcodec/mjpegdec: Avoid mixing return value and error code, avoid branch
mjpeg_decode_dc() currently has a special return value (0xfffff)
for the case of invalid data; this value does not overlap with
the ordinary return values, yet the compiler can't prove this
(at least on x86 where an asm version of NEG_USR32 is used
inside get_xbits()), so the non-error return value has to be checked
for being the special value even if mjpeg_decode_dc() is inlined.

This commit avoids this by separating error code and ordinary return
value. It also means that the ljpeg functions return the proper
error code and not -1 in case of invalid data.

    tests/fate-run: add support for specifying the final encode muxer in `transcode`
This allows for direct dumping of the packets' contents (useful for
text based formats), while getting the timestamps/sizes etc from
ffprobe.

If used via TRANSCODE, the actually utilized muxer should be added
within the last argument as an additional dependency, as that is not
done automatically.

Attempts to base the fragmentation timing on other streams
as most receivers expect media fragments to be more or less
aligned.

Currently does not support fragmentation on subtitle track
only, as the subtitle packet queue timings would have to be

    avcodec/decode: sync initial_pict_type and intra_only_flag with thread worker's avctx
Regression since 5acbdd2264d3b90dc11369f9e031e762f260882e, which removed
setting both values from PerThreadContext.
Given the pthread code calls ff_decode_receive_frame_internal() on the frame,
any value set before it will be overwritten, so instead sync each thread's
DecodeContext and let ff_decode_receive_frame_internal() handle these values.

Fixes issue #20534.

    avutil/hwcontext_d3d11va: remove D3D11_BIND_RENDER_TARGET restriction for array textures
This was added in 4f78711f9c28b11dae4e4b96be46b6b4925eb8c6, with the
commit message claiming that it's a Microsoft restriction that array
textures with ArraySize > 2 cannot be created with
D3D11_BIND_RENDER_TARGET.

I was unable to find any documentation or other references on that, and
a quick test also found it to not be the case. So this patch removes
that restriction.

This enables frame sources, like the d3d11 capture filters, to output
frames in an array texture, which is neccesary to pass those frames as
input to some hardware encoders.

    avformat/tls_gnutls: add initial dtls support
Set GNUTLS_DATAGRAM flag when is_dtls is true.
Set mtu when it's specified.
Modify the read/write function could use udp socket.

There are more patches to make dtls really work.

    vp9: Remove 8bpc AVX asm for inverse transforms
There's very little performance difference vs SSE2/SSSE3 and most
systems will use the AVX2 implementations anyway.

This reduces code size and compilation time by a significant amount.

    lavf: fix demuxing of FLAC files with id3v2 tags
Due to the recent id3v2 refactor, FLAC was left out due to
earlier code not checking for id3v2 presence on FLAC.
Without the id3v2 data parsed, detection of FLAC and therefore
demuxing fails.

    fftools/opt_common: add separator line to show_filters output
Add a separator line to show_filters() function output to maintain
consistent formatting with other show functions like show_codecs,
show_formats_devices, etc. This provides uniform formatting across

    avcodec/h274: Make H274FilmGrainDatabase a shared object
Right now, the private contexts of every decoder supporting
H.274 film grain synthesis (namely H.264, HEVC and VVC)
contain a H274FilmGrainDatabase; said structure is very large
700442B before this commit) and takes up the overwhelming
majority of said contexts: Removing it reduces sizeof(H264Context)
by 92.88%, sizeof(HEVCContext) by 97.78% and sizeof(VVCContext)
by 99.86%. This is especially important for H.264 and HEVC
when using frame-threading.

The content of said film grain database does not depend on
any input parameter; it is shareable between all its users and
could be hardcoded in the binary (but isn't, because it is so huge).

This commit adds a database with static storage duration to h274.c
and uses it instead of the elements in the private contexts above.
It is still lazily initialized as-needed; a mutex is used
for the necessary synchronization. An alternative would be to use
an AV_ONCE to initialize the whole database either in the decoders'
init function (which would be wasteful given that most videos
don't use film grain synthesis) or in ff_h274_apply_film_grain().

    Revert "avformat/tls_openssl: add av_assert0() for tls_shared"
This reverts commits fd55c4b5f72a157fbb128d0ef203e9922b53552b
(for tls_openssl.c) and c74181a04b5f4e650eae662231e56518daef64d4
(for tls_gnutls.c).

It is impossible for a pointer to a member of a structure
to be NULL: If the containing structure exists, the member
exists and can't have a NULL address; if the containing
structure does not exist, then getting a pointer to the
substructure via &c->tls_shared would already be undefined
behavior.

    avformat/mov: Merge tts after building index for old-style uncompressed PCM
This was a regression introduced in 292c1df7c159c8a1a7afe52613d164ff417e81ce.

Since we don't know the length of the stts data until after building the
index, since we're generating it, we need to merge any ctts data after,
since otherwise tts_count is set to 0, and no packets will be output.

We can't remove the merge entirely, because uncompressed PCM with
a ctts atom is technically valid (e.g. a constant CTS offset).

This fixes old-style uncompressed PCM demuxing.

Fixes #11490.

    avfilter/vf_libplacebo: force premultiplied blending for linear texture
Blending onto independent alpha framebuffers is not possible under the
constraints of the supported blend operators. While we could handle
blending premul-onto-premul, this would break if the base layer is YUV,
since premultiplied alpha does not survive the (nonlinear) YUV conversion.

Fortunately, blending independent-onto-premul is just as easy, and works in
all cases. So just force this mode when using a linear intermediate blend
texture, which is always RGBA.

    avformat/http: Handle IPv6 Zone ID in hostname
When using a literal IPv6 address as hostname, it can contain a Zone ID
especially in the case of link-local addresses. Sending this to the
server in the Host header is not useful to the server and in some cases
servers refuse such requests.

To prevent any such issues, strip the Zone ID from the address if it's
an IPv6 address. This also removes it for the Cookies lookup.

    avcodec/libjxldec: submit frame after file is complete
This commit causes the libjxl decoder wrapper to hold onto the decoded
frame until the trailing metadata after the frame is possibly complete
before it submits the frame. This allows EXIF and other metadata boxes
that occur after the frame is fully rendered to be attached to it as
side data.

    configure: suppress C4267 warnings from MSVC
Suppresses implicit integer conversion narrowing warnings:
warning C4267: 'initializing': conversion from 'size_t' to 'int', possible loss of data

Those implicit conversions are abundant in ffmpeg's code base.
Additionally equivalent warnings are not enabled for GCC/Clang by
default, so they are mostly left unfixed.

Suppress reports about them to reduce noise in MSVC build log.

    avcodec/libmpeghdec: Don't use too big buffer
The channel count is fixed, so we don't need to allocate
space to hold samples for nonexisting channels. This also
means that the maximum channel count is no longer hardcoded
in the macro.
Also switch to decoder_buffer_size to be samples-based.

It indicates a constant frame size (in samples); yet the documentation
of the MPEGH_DECODER_OUTPUT_INFO structure says that it
"gives information about the currently decoded audio data"
and makes no guarantees about it being constant.

    avcodec/hpeldsp: Fix documentation
This commit fixes two issues in the documentation:
a) The documentation for {put,avg}_pixels_tab only mentions
widths 16 and 8, although it explicitly mentions that there
are four horizontal blocksizes. This part of the patch
basically reverts e5771f4f37b67951485205e110f4da5e7e32ea74.
b) The restrictions on height don't match the reality. While
most users abide by it, some do not:
i) vp56.c copies a 16x12 block.
ii) indeo3 can copy an arbitrary multiple of four lines
for block widths 4, 8 and 16.
iii) SVQ3 can use block sizes luma block sizes 16x16, 8x16,
16x8, 8x8, 4x8, 8x4 and 4x4 and the corresponding
8x8, 4x8, 8x4, 4x4, 2x4, 4x2 and 2x2 chroma block sizes.

This implies that for widths 2 and 4 height can be two
and is guaranteed to be at least even. For all other widths,
height can be a multiple of four.

Furthermore, a comment for the SVQ3 blocksizes has been added.

    avcodec/hpel_template: Fix unintentional usage of unsigned offsets
The value of sizeof() is of type size_t which means that
an expression like
src1[i * src_stride1 + 4 * (int)sizeof(pixel)]
will use a very large offset if src_stride1 is sufficiently negative.
It works in practice (because it is correct modulo SIZE_MAX),
but UBSan treats it as error:
libavcodec/hpel_template.c:104:1: runtime error: addition of unsigned offset to 0x7ffdfa0391d8 overflowed to 0x7ffdfa0391cc
Fix this by casting sizeof(pixel) to int.

(This has been uncovered by a checkasm test for the hpeldsp
which will be added in a later commit.)

    avcodec/x86/qpeldsp_init: Use SSE2 versions where possible
The mc00 versions (i.e. the qdsp functions with no subpixel
interpolation) are just wrappers around their fpel versions.
There are SSE2 versions of these, yet the qpel code only
uses the MMX(EXT) versions. This commit changes this and
also removes the MMX(EXT) versions.

This also allowed to remove ff_avg_pixels16_mmxext,
ff_put_pixels16_mmx.

    avcodec/x86/hpeldsp_init: Remove MMX(EXT) funcs overridden by SSSE3
SSSE3 is already quite old (introduced 2006 for Intel, 2011 for AMD),
so that the overwhelming majority of our users (particularly those
that actually update their FFmpeg) will be using the SSSE3 versions.
This commit therefore removes the MMX(EXT) functions overridden
by them (which don't abide by the ABI) to get closer to a removal
of emms_c.

Also merge the mpegvideoenc_qns_template.c file into the main file.

    avfilter/x86/vf_gradfun: Remove MMXEXT func overridden by SSSE3
SSSE3 is already quite old (introduced 2006 for Intel, 2011 for AMD),
so that the overwhelming majority of our users (particularly those
that actually update their FFmpeg) will be using the SSSE3 version
of filter_line.
This commit therefore removes the overridden MMXEXT version
(which didn't abide by the ABI) which allows us to remove
an emms_c() from vf_gradfun.c, so that users with SSSE3 no longer
pay a price for the mere existence of an MMXEXT version.

    avcodec/hpeldsp: Make put_no_rnd_pixels_tab smaller
Only the blocksizes 16 and 8 are implemented, yet the motion estimation
code touches the blocksize 4 entries. But really nothing touches
the blocksize 2 entries, so that we can reduce the put_no_rnd_pixels_tab
array size to [3][4].

    fftools/ffmpeg_sched: relax queue size assertion
The code in the decoder just cares about allocating enough extra hw frames
to cover the size of the queue; but there's no reason we actually *have* to
use this many. We can safely relax the assertion to a <= check.

    fftools/ffmpeg_sched: lower default frame queue size
I tested this extensively under different conditions and could not come up
with any scenario where using a larger queue size was actually beneficial.
Moreover, having such a large default queue is very wasteful especially
for larger frame sizes; and can in the worst case lead to an extra ~50% memory
footprint per input (with the default 16 threads), regardless of whether that
input is currently in use or not.

My methodology was to add logging in the event of a queue underrun/overrun,
and then observe and then observe the frequency of such events in practice,
as well as the impact on performance. I came up with an example filter graph
involving decoding, filtering and encoding with several input files and
various changes to move the bottleneck around.

I found that, in all configurations I tested, with all thread counts and
bottlenecks, using a queue size of 2 frames yielded practically identical
performance to a queue size of 8 frames. I was only able to consistently
measure a slowdown when restricting the queue to a single frame, where the
underruns ended up making up almost 1.1% of frame events in the worst case.

A summary of my test log follows:

    fftools/ffmpeg_sched: get rid of src_sched
This field is just saving (typically) a single pointer indirection; and IMO
makes the logic and graph relations unnecessarily complicated. I am also
considering adding choking logic to decoders and encoders as well, which this
field would get in the way of.

Apart from the unchoking logic in unchoke_for_input(), the only other place
that uses this field is the (cold) function check_acyclic(), which can be
served just as well with a simple function to do the graph traversal there.

    fftools/ffmpeg_sched: choke inputs during filtergraph configuration
Currently, while the filter graph is being initially created, the scheduler
continues demuxing frames on the last input that happened to be active before
the filter graph was complete.

This can lead to an excess number of decoded frames "piling" up on this input,
regardless of whether or not it will actually be requested by the configured
filter graph. Suspending the filter graph during this initialization phase
reduces the amount of wasted memory.

    fftools/thread_queue: allow choking thread queues directly
Currently, when a demuxer thread is choked, it will avoid queuing more
packets, but any packets already present on the thread queue will still be
processed.

This can be quite wasteful if the choke is due to e.g. decoder not being
needed yet, such as in a filter graph involving concatenation-style filters.
Adding the ability to propagate the choke status to the thread queue directly
allows downstream decoders and filter graphs to avoid unnecessary work and
buffering.

Reduces the effective latency between scheduler updates and changes in the
thread workfload.

    fftools/ffmpeg_sched: forward demuxer choke status to dst queues
Cut off a choked demuxer's output codec/filter queues, effectively preventing
them from processing packets while the demuxer is choked. Avoids downstream
nodes from piling up extra input that a demuxer shouldn't currently be
sending.

The main benefit of this is to avoid queuing up excess packets that don't want
to be decoded yet, reducing memory consumption for idle inputs by preventing
them from being read earlier than needed.

    fftools/ffmpeg_sched: close stream when sch_filter_send receives EOF
THis is currently done by sch_demux_send() (via demux_stream_send_to_dst()),
sch_enc_send() (via enc_send_to_dst()), and sch_dec_send() (via
dec_send_to_dst()), but not by sch_filter_send().

Implement the same queue-closing logic for them. The main benefit here is that
this will allow them to mark downstream inputs as send-done (in addition
to received-done), which is useful for a following commit.

    fftools/ffmpeg_sched: unchoke upstream nodes on recv-closed filter inputs
This allows upstream filters to observe EOF on their corresponding outputs
and terminate early, which is particularly useful for decoders and demuxers
that may then gracefully release their resources.

Prevents "leaking" memory for previously used, but now unused, filter inputs.

    avfilter/vf_libplacebo: introduce `fit_mode` option
The semantics of these keywords are well-defined by the CSS 'object-fit'
property. This is arguably more user-friendly and less obtuse than the
existing `normalize_sar` and `pad_crop_ratio` options. Additionally, this
comes with two new (useful) behaviors, `none` and `scale_down`, neither of
which map elegantly to the existing options.

One additional benefit of this option is that, unlike `normalize_sar`, it
does *not* also imply `reset_sar`; meaning that users can now choose to
have an anamorphic base layer and still have the overlay images scaled to fit
on top of it according to the chosen strategy.

    avcodec/amfenc: avoid unnecessary output delay in low delay mode
The code optimizes throughput by letting the encoder work on frame N
until frame N+1 is ready for submission, but this hurts low-delay uses
by delaying output by one frame. Don't delay output beyond what is
necessary when AV_CODEC_FLAG_LOW_DELAY is used.

    avcodec/x86/qpel: Remove always-false branches
The ff_avg_pixels{4,8,16}_l2_mmxext() functions are only ever
used in the last step (the one that actually writes to the dst buffer)
where the number of lines to process is always equal to the
dimensions of the block, whereas ff_put_pixels{8,16}_mmxext()
are also used in intermediate calculations where the number of
lines can be 9 or 17.

The code in qpel.asm uses common macros for both and processes
more than one line per loop iteration; it therefore checks
for whether the number of lines is odd and treats this line separately;
yet this special handling is only needed for the put functions,
not the avg functions. It has therefore been %if'ed away for these.

The check is also not needed for ff_put_pixels4_l2_mmxext() which
is only used by H.264 which always processes four lines. Because
ff_{avg,put}_pixels4_l2_mmxext() processes four lines in a single loop
iteration, not only the odd-height handling, but the whole loop
could be removed.

    configure: Remove vc1dsp->qpeldsp dependency
It only needs it for some x86 fpel functions; instead
add a direct dependency for that.

    avcodec/h264qpel: Don't build unused 2x2 size funcs for bitdepths > 8
The 2x2 put functions are only used by Snow and Snow uses
only the eight bit versions. The rest is dead code. Disabling
it saved 41277B here.

    avcodec/h264qpel: Make avg_h264_qpel_pixels_tab smaller
avg_h264_qpel only supports 16x16,8x8 and 4x4 blocksizes,
so it is currently unnecessarily large.

    avcodec/fpel: Avoid loop in ff_avg_pixels4_mmxext()
It is only used by h264_qpel.c and only with height four
(which is unrolled) and uses a loop in order to handle
multiples of four as height. Remove the loop and the height
parameter and move the function to h264_qpel_8bit.asm.
This leads to a bit of code duplication, but this is simpler
than all the %if checks necessary to achieve the same outcome
in fpel.asm.

    avcodec/x86/h264_qpel: Add ff_{avg,put}_pixels16_l2_shift5_sse2
Up until now this function was emulated via two calls
to ff_{avg,pull}_pixels8_l2_shift5_mmxext(). Adding a dedicated
function proved beneficial both size wise and performance wise:
The new functions take 192B, yet the simplified calls save
256B with GCC and 320B with Clang here.

This change will also allow further optimizations.

ff_{avg,put}_h264_qpel8or16_hv2_lowpass_ssse3()
currently is almost the disjoint union of the codepaths
for sizes 8 and 16. This size is a compile-time constant
at every callsite. So split the function and avoid
the runtime branch.

    avcodec/x86/h264_qpel_8bit: Replace qpel8_h_lowpass_l2 MMXEXT by SSE2

As can be seen, the SSE2 version is often neck-to-neck with the SSSE3
version (which also benefits from a better hv2_lowpass SSSE3
implementation for mc21 and mc23) for eight byte block sizes.
Unsurprisingly, SSSE3 beats SSE2 for 16x16 blocks: For SSE2,
these blocks are processed by calling the 8x8 function four times
whereas SSSE3 has a dedicated function (on x64).
This implementation should also be extendable to an AVX version
for 16x16 blocks.

    avcodec/x86/h264_qpel: Add ff_{avg,put}_h264_qpel16_h_lowpass_l2_sse2()
These functions are currently emulated via four calls to the versions
for 8x8 blocks. In fact, the size savings from the simplified calls
in h264_qpel.c (GCC 1344B, Clang 1280B) more than outweigh the size
of the added functions (512B) here.

It is also beneficial performance-wise. Old benchmarks:

Notice that the SSSE3 versions of mc21 and mc23 benefit from
an optimized version of hv2_lowpass.

Also notice that there is no SSE2 version of the purely horizontal
motion compensation. This means that src2 is currently always aligned
when calling the SSE2 functions (and that srcStride is always equal
to the block width). Yet this has not been exploited (yet).

    avcodec/x86/h264_qpel_10bit: Remove SSE2 "cache64" duplicates
The horizontal 10bit MC SSE2 functions are currently duplicated:
They exist both in ordinary form as well as with a "sse2_cache64"
suffix. A comment in ff_h264qpel_init_x86() indicates that this
is due to older processors not liking accesses that cross cache
lines, yet these functions are identical to the non-cache64
functions (apart from the unavoidable changes in the rip-offset).

The only difference between these functions and the ordinary ones
are that the cache64 ones are created via a special form of the
INIT_XMM macro: "INIT_XMM sse2, cache64". This affects the name
and apparently defines cpuflags_cache64, yet nothing checks for
this, so both versions are identical. So remove the cache64 ones
and treat the remaining ones like ordinary SSE2 functions.

    avfilter/blend_modes: Use stride in bytes
The blend functions currently convert strides from bytes to elements
of the type by using the stride /= sizeof(pixel) idiom. Yet this has
several drawbacks:
1. It invokes undefined behavior that happens to work when stride is
negative: size_t is typically the unsigned type of ptrdiff_t and
therefore the division will be performed as size_t, i.e. use logical
right shifts, making stride very big when sizeof(pixel) is > 1. This
works, because pointer to pixel for accesses entails an implicit
factor of sizeof(pixel) so that everything is correct modulo SIZE_MAX.
Yet this is UB and UBSan complains about it.
2. It makes the compiler emit actual shifts/ands to discard the low bits
shifted away.
3. There may be systems where alignof(uint16_t) or alignof(float) is
strictly smaller than their sizeof, so that the stride (in bytes) is
not guaranteed to be multiple of these sizeofs. In this case, dividing
by sizeof(pixel) is simply wrong.

    avfilter/blend_modes: Don't build duplicate functions
Some of the blend mode functions only depend on the underlying type
and therefore need only one version for 9, 10, 12, 14, 16 bits.
This saved 35104B with GCC and 26880B with Clang.

    avformat/mccenc: use Lavf version string instead of FFmpeg
The muxed subtitle is created by libavformat, and as such that's what should be
reported. This is in line with the string we write for every other muxer.
After this change, the muxer will no longer be recompiled every time a commit
is made.

    avcodec/x86/h264_qpel: Split hv2_lowpass_sse2 into size 8,16 funcs
This is beneficial size-wise: 384B of new asm functions are more
than outweighted by 416B savings from simpler calls here (for size 16,
the size 8 function had been called twice).
It also makes the code more readable, as it allowed to remove
several wrappers in h264_qpel.c.

It is also beneficial performance-wise. Old benchmarks:

    avcodec/x86/h264_qpel: Simplify macros
1. Remove the OP parameter from the QPEL_H264* macros. These are
a remnant of inline assembly and were forgotten in
610e00b3594bf0f2a75713f20e9c4edf0d03a818.
2. Pass the instruction set extension for the shift5 function
explicitly in the macro instead of using magic #defines.
3. Likewise, avoid magic #defines for (8|16)_v_lowpass_ssse3.

    avcodec/x86/cavsdsp: Fix vertical qpel motion compensation
The prediction involves terms of the form
(-1 * s0 - 2 * s1 + 96 * s2 + 42 * s3 - 7 * s4 + 64) >> 7,
where the s values are in the range of 0..255.
The sum can have values in the range -2550..35190, which
does not fit into a signed 16bit integer. The code uses
an arithmetic right shift, which does not yield the correct
result for values >= 2^15; such values should be clipped
to 255, yet are clipped to 0 instead.

Fix this by shifting the values by 4096, so that the range
is positive, use a logical right shift and subtract 32.

bunny.mp4 from the FATE suite can be used to reproduce the problem.

    avcodec/x86/cavsdsp: Add SSE2 mc20 horizontal motion compensation
Basically a direct port of the MMXEXT one. The main difference
is of course that one can process eight pixels (unpacked to words)
at a time, leading to speedups.

    avcodec/x86/cavs_qpel: Add SSE2 vertical motion compensation
This is not based on the MMXEXT one, because the latter is quite
suboptimal: Motion vector types mc01 and mc03 (vertical motion vectors
with remainder of one quarter or three quarter) use different neighboring
lines for interpolation: mc01 uses two lines above and two lines below,
mc03 one line above and three lines below. The MMXEXT code uses
a common macro for all of them and therefore reads six lines
before it processes them (even reading lines which are not used
at all), leading to severe register pressure.

Another difference to the old code is that the positive and negative
parts of the sum to calculate are accumulated separately and
the subtraction is performed with unsigned saturation, so
that one can avoid biasing the sum.

The fact that the mc01 and mc03 filter coefficients are mirrors
of each other has been exploited to reduce mc01 to mc03.

But of course the most important different difference between
this code and the MMXEXT one is that XMM registers allow to
process eight words at a time, ideal for 8x8 subblocks,
whereas the MMXEXT code processes them in 4x8 or 4x16 blocks.

    avcodec/x86/fpel: Add blocksize x blocksize avg/put functions
This commit deduplicates the wrappers around the fpel functions
for copying whole blocks (i.e. height equaling width). It does
this in a manner which avoids having push/pop function arguments
when the calling convention forces one to pass them on the stack
(as in 32bit systems).

    avcodec/sanm: partially fix codec48
The mv check introduced with d5bdb0b705ce broke MotS videos:
- their height (300 lines) is 37,5 blocks; unfortunately the videos try to
  access up to 1 block more.
  Extend the mv check to the aligned_height, which fixes most artifacts.
- don't return an error when an mv is invalid; rather skip the (subblock).
  Gets rid of almost all artifacts.

Some artifacts still remain, esp in space scenes where the original
encoder apparently fetched black pixels from outside of the aligned
height.  An increase of the buffer size by 8 lines will fix that later.

    avcodec/sanm: handle FTCH on video start
some videos have a FTCH at the start of the video, to restore the
last image produced by the previous game file.  This leads to
ugly messages like these:

[sanm @ 0x7f18cc001980] [IMGUTILS @ 0x7f18d7ffe8e0] Picture size 0x0 is invalid
[sanm @ 0x7f18cc001980] video_get_buffer: image parameters invalid
[sanm @ 0x7f18cc001980] get_buffer() failed

Fix this by not setting the got_frame_ptr when there is nothing to
restore/fetch.  Seen with a lot of RA1 and the RA2 Level 11/12 videos.

    avcodec/sanm: codec48: reimplement block scaling
Reimplement opcodes 0xFF and 0xFD the same way the c48 decoder
in the "Mysteries of the Sith" game engine does it:
The source pixel(s) and various pixels from inside the same and above
block of the second to last image rendered to the destination buffer
are used together with the interpolation table to generate a 4x4 pattern,
which is then expanded by doubling each pixel horizontally and vertically
to produce the final 8x8 block.

This fixes visible artifacts in frames 25-50 of the S1L1OCS.SAN
video of Mysteries of the Sith.

This implements XPAL the same way the DOS/Windows players do, with an
additional 768-entry table holding the palette left-shifted by 7 bits,
and adding the deltapal values to this.

This results in a perfectly smooth day-to-night transition in the last
30 seconds of the Outlaws RAE.SAN (ending) video, while before there
were visible brightness "pulses" when a new palette was loaded.
It also fixes color banding in the The Dig Intro (sq1.san), in the

    avcodec/sanm: codec37/47/48 updates
- align the incoming widths to 4(c37) / 8(c47/78) pixels. LucasArts
   game videos have these aligned.
- since these codecs use their 2/3 buffers for themselves, adjust the
  stride to the aligned width, keeping it even, which gets rid of
  an unaligned store in c48_4to8() found by the fuzzer with an
  odd stride.
- clear the whole diff buffer, not just the area described by w/h.
- adjust the RLE "decoded_size" to the product of the aligned width
   and reported height.

These changes are the result of various fuzzer-found issues; all my
test videos still work fine.

    avcodec/sanm: implement 3 blits for codec37/47/48
The various game engines implement the following blit types, from the decoded
result to the main canvas:
- normal (opaque) blit (c37/c47/c48)
- masked blit (c37/c48)
- interpolated-frame blit (c48)
  Here an artificial frame is generated by looking up the pixels
  from both buffers and picking a color from the interpolation table
  for the artificial frame.
  This is only supported in the decoder of "Making Magic".

Implement and hook up these 3 schemes for each of the 3 compresstion types,
and switch codec20 to a call to the opaque blit function.

Refer to RFC 9725 4.2,
"Once a session is set up, consent freshness as per
[RFC7675] SHALL be used to detect non-graceful
disconnection by full ICE implementations and DTLS
teardown for session termination by either side"

Refer to RFC 7675,
send STUN Binding request every 5s,
expire consent after 30s without response,
terminate session when the consent expired.

TODO:
Random consent check interval (4-6s) will be
added later.

    avformat/whip: remind user increase -buffer_size
The udp buffer size might be too small to easily
be full temporarily and return WSAEWOULDBLOCK.
The udp code will handle the windows error code
and convert it to AVERROR(EAGAIN).

This issue just can be reproduced on windows.

If sleep a interval and retry to send pkt when hit
EAGAIN, it will increase latency, and appropriate
interval is hard to define.

So this patch just remind user increase the buffer
size via -buffer_size to avoid this issue.

    avcodec/exif: avoid printing errors for makernote non-IFD parsing
When we parse a MakerNote, we first try to parse it as an IFD and if
that fails, we try to re-parse it as a binary blob. This is because
MakerNote is not well-documented in its nature.

However, if we fail to parse it the first time, we should not av_log
error messages about the parse failure, so instead we log these as
AV_LOG_DEBUG.

    avcodec/x86/hpeldsp: Add ff_put_no_rnd_pixels8_xy2_ssse3()

unsurprising that SSE2 wins against MMX; the MMX version has
therefore been removed (as well as the now unused inline_asm.h).
The new function is even 32B smaller than the old MMX one.

    avcodec/x86/hpeldsp: Improve ff_{avg,put}_pixels8_xy2_ssse3()
This SSSE3 function uses MMX registers (of course without emms
at the end) and processes eight bytes of input by unpacking
it into two MMX registers. This is very suboptimal given
that one can just use XMM registers to process eight words.
This commit switches them to using XMM registers.

    avcodec/x86/vp3dsp: Port loop filters to SSE2
The old code operated on bytes and did lots of tricks
due to their limited range; it did not completely succeed,
which is why the old versions were not used when bitexact
output was requested.

In contrast, the new version is much simpler: It operates
on signed 16 bit words whose range is more than sufficient.
This means that these functions don't need a check for bitexactness
(and can be used in FATE).

Old benchmarks (for this, the AV_CODEC_FLAG_BITEXACT check has been
removed from checkasm):
h_loop_filter_c:                                        29.8 ( 1.00x)
h_loop_filter_mmxext:                                   32.2 ( 0.93x)

    lavc/vvc: Store RefStruct references to referenced PSs/headers in slice
This loosens the coupling between CBS and the decoder by no longer using
CodedBitstreamH266Context (containing the most recently parsed PSs & PH)
to retrieve the PSs & PH in the decoder. Doing so is beneficial in two
ways:
1. It improves robustness to the case in which an AVPacket doesn't
   contain precisely one PU.
2. It allows the decoder parameter set manager to properly handle the
   case in which a single PU (erroneously) contains conflicting
   parameter sets.

    avcodec/x86/mpegvideoencdsp_init: Use xmm registers in SSSE3 functions
Improves performance and no longer breaks the ABI (by forgetting
to call emms).

Old benchmarks:
add_8x8basis_c:                                         43.6 ( 1.00x)
add_8x8basis_ssse3:                                     12.3 ( 3.55x)

New benchmarks:
add_8x8basis_c:                                         43.0 ( 1.00x)
add_8x8basis_ssse3:                                      6.3 ( 6.79x)

Notice that the output of try_8x8basis_ssse3 changes a bit:
Before this commit, it computes certain values and adds the values
for i,i+1,i+4 and i+5 before right shifting them; now it adds
the values for i,i+1,i+8,i+9. The second pair in these lists
could be avoided (by shifting xmm0 and xmm1 before adding both together
instead of only shifting xmm0 after adding them), but the former
i,i+1 is inherent in using pmaddwd. This is the reason that this
function is not bitexact.

The documentation states that this field is for enabling "extra" usage

though.

In resolving this ambiguity, I think it's better to lean towards the first
sentence and treat this field purely as specifying *extra* usage flags to
enable. Otherwise, this may break vulkan encoding or subsequent hwdownload
if the upstream filter did not specifically advertise this.

Change the default behavior and update the documentation slightly to more
clearly document the semantics.

    movenc: Make the hybrid_fragmented mode more robust
Write the moov tag at the end first, before overwriting the mdat size
at the start of the file.

In case writing the final moov box fails (e.g. due to being out
of disk), we haven't broken the initial moov box yet.

Thus if writing stops between these steps, we could end up with
a file with two moov boxes - which arguably is more feasible to
recover from, than from a file with no moov boxes at all.

    avfilter/vf_nlmeans_vulkan: rewrite filter
This is a major rewrite of the exising nlmeans vulkan code, with bug
fixes and major performance improvement.

Fix visual artifacts found in ticket #10661, #10733. Add OOB checks for
image loading and patch sized area around the border. Correct chroma
plane height, strength and buffer barrier index.

Improve parallelism with component workgroup axis and more but smaller
workgroups. Split weights pass into vertical/horizontal (integral) and
weights passes. Remove h/v order logic to always calculate sum on
vertical pass. Remove atomic float requirement, which causes high memory
locking contentions, at the cost of higher memory usage of w/s buffer.
Use cache blocking in h pass to reduce memory bandwidth usage.

    avcodec/x86/me_cmp: Add SSE2 sad 8,16 xy2 functions
The new functions are faster than the existing exact
functions, yet get beaten by the nonexact functions
(they can avoid unpacking to words and back).
The exact (slow) MMX functions have therefore been
removed, which was actually beneficial size-wise
(416B of new functions, 619B of functions removed).

    avcodec/x86/me_cmp: Remove MMXEXT functions overridden by SSE2
The SSE2 function overriding them are currently only set
if the SSE2SLOW flag is not set and if the codec is not Snow.
The former affects only outdated processors (AMDs from
before Barcelona (i.e. before 2007)) and is therefore irrelevant.
Snow does not use the pix_abs function pointers at all,
so this is also no obstacle.

    avcodec/x86/me_cmp: Replace MMXEXT size 16 funcs by unaligned SSE2 funcs
Snow calls some of the me_cmp_funcs with insufficient alignment
for the first pointer (see get_block_rd() in snowenc.c);
therefore SSE2 functions which really need this alignment
don't get set for Snow and 542765ce3eccbca587d54262a512cbdb1407230d
consequently didn't remove MMXEXT functions which are overridden
by these SSE2 functions for normal codecs.

For reference, here is a command line which would segfault
if one simply used the ordinary SSE2 functions for Snow:

./ffmpeg -i mm-short.mpg -an -vcodec snow -t 0.2 -pix_fmt yuv444p \
-vstrict -2 -qscale 2 -flags +qpel -motion_est iter 444iter.avi

This commit adds unaligned SSE2 versions of these functions
and removes the MMXEXT ones. This in particular implies that
sad 16x16 now never uses MMX which allows to remove an emms_c
from ac3enc.c.

Benchmarks (u means unaligned version):

    avcodec/x86/fpel: Port ff_put_pixels8_mmx() to SSE2
This has the advantage of not violating the ABI by using
MMX registers without issuing emms; it e.g. allows
to remove an emms_c from bink.c.

This commit uses GP registers on Unix64 (there are not
enough volatile registers to do likewise on Win64) which
reduces codesize and is faster on some CPUs.
