tests: Implicitly set TAG=GEN for data/*.m3u8
This avoids having to declare it for every rule that generates
test input data, and adds such a missing tag for
tests/data/hls-seek.m3u8.

This fixes a case of a missing TAG for data/hls-seek.m3u8, which
caused it to be printed without a tag, like
"        tests/data/hls-seek.m3u8", now printed as
"GEN     tests/data/hls-seek.m3u8" as expected.

avformat/movenc: unify remainder samples signaling
When writing edit lists and the last packet has skip samples side data to
report discard padding, for codecs that have a fixed frame size it's best to
always use the full packet duration to calculate track duration (and thus
bitrate in some cases) and let the edit list be the sole source of triming
information.

checkasm/sw_rgb: fix too small source stride in uyvytoyuv422 test
The planes table stored a source stride smaller than the 2*width bytes a
packed UYVY line occupies (e.g. width 12 with stride 12), and the correct
stride for width 128 would be 256, which does not even fit the uint8_t
field. The test passed only because the oversized source buffer absorbed
the resulting out-of-bounds reads.

Derive srcStride from the width (2*width) instead of storing it, so each
line is passed its true size.

checkasm/sw_rgb: test uyvytoyuv422 with odd widths
The SIMD uyvytoyuv422 implementations only handled even widths correctly.
Add odd width and 1x1 entries so the trailing column handling is exercised
against the C reference.

An odd width reads one source byte more than 2*width, the V sample at
src[2w], so the stride is extended by one for odd widths.

checkasm/sw_rgb: also test yuyvtoyuv422
yuyvtoyuv422 reads the trailing odd V sample at src[2w+1], one byte further
than uyvytoyuv422, so the number of extra source bytes an odd width needs is
passed in per format (1 for UYVY, 2 for YUYV) and added to the stride.

uyvytoyuv420 and yuyvtoyuv420 are intentionally not added: their x86 mmxext
chroma averaging uses PAVGB rounding and so is not bit-exact with the C
reference, which truncates, so they cannot be verified this way.

2.) The coeffs were windowed, which was wrong.

3.) The applied filter did not match what the spec required.

aacpsy: pre-echo-aware short-block detection for isolated onsets
The LAME attack detector high-pass filters at fs/4 before measuring attack
intensity, so the gentler attacks of tonal material (piano, plucked strings)
fall below the threshold and stay in long blocks, smearing pre-echo across the
quiet gap before the note. Relax the attack threshold for an isolated onset,
preceded by PSY_LAME_PE_GAP long frames with a near-silent pre-onset sub-block
(< PSY_LAME_PE_QUIET of the frame peak), so it switches to short blocks.

configure: Add a dependency on user32 to the gfxcapture filter
This filter uses a bunch of user32 functions, like GetMessage,
DispatchMessage, PeekMessage, GetWindowRect, etc.

This makes it clear that if the gfxcapture filter is built, we
need to link user32, if other components that depend on user32
would happen to be disabled.

Separately, if targeting UWP (with -DWINAPI_FAMILY=WINAPI_FAMILY_APP)
then these user32 APIs are unavailable. We have an existing
configure check for user32, checking for the GetShellWindow
function. This function isn't used by gfxfilter, but its
availability on UWP matches the other functions that gfxfilter
uses.

This fixes builds for UWP, by excluding the gfxcapture filter.
(This is somewhat ironic, as the gfxcapture filter uses
"winrt" APIs - but the implementation of the filter also relies
on lots of APIs that are unavailable in UWP/"winrt".)

tests/fate/generic-tags: use codec copy instead of encoding
Using ac3_fixed output was not enough as there's float to int conversion due to
the fact the mp3float decoder is used.
Instead of playing with codec combinations, just remove encoding from the test
altogheter. Mov supports muxing mp3 just fine.

avcodec/aacenc: export discard padding side data when needed
This is in line with other encoders, and is needed by the matroska muxer
to properly signal end trimming samples.

gaplessenc-pcm-to-mov-aac changes as the mov muxer now uses this information
when writing the edit list, so the shorter frame duration is not needed.

vulkan_decode: drop ff_vk_decode_prepare_frame_sdr, use exec owned views
For SDR codecs, we have zero dependency on the images we decode. So using
the same scheme as the software code led us to needing unnecessarily to block
on a semaphore wait.

Instead of doing this, just make the imageviews a dependency of the exec context.
Saves on CPU, matters particularly for very fast decoding speeds.

FFv1 gets a slight workaround that's still better than what we did before.

ffv1enc_vulkan: gather slices on the GPU, drop the transfer copy
Uses the gather shader from the APV encoder to copy the packet data on
the GPU with a second pass.

Replace all of that with a seg_gather compute dispatch in the
same submission as the encode. It packs the per-slice slots tight and in
order into a contiguous host-visible buffer, so the final packet is just
the sum of the per-slice sizes and the gathered buffer is handed straight
to pkt->buf with no extra submit, no copy, no CPU involvement.

The slots are sized with the version-4 worst-case formula (the realistic
lossless bound, ~17x tighter than the version-3 budget this encoder never

to a 16-byte multiple so the gather reads them with aligned wide loads.

Removes the transfer queue family, its exec pool, and the buf_regions

vulkan/prores_raw: reconstruct DC values in 32-bit
DCs can go over int16_t, and when it does, dc_add wraps, so the wrong sign
is reported, which causes errors when decoding more DCs.

Do the prediction in int and narrow to int16 only at store time. The
read_ac_vals() sign change is cosmetic (the value is only ever 0/-1, and
the old code already widened it).

avcodec/vulkan_apv: store coefficients in a flat buffer, not the image
The entropy pass wrote each decoded coefficient into the output image as
16-bit scratch, then the iDCT pass read it back, dequantised it and
overwrote the same texel with the final pixel. Routing the coefficients
through the image couples the two passes to the image layout and forces
the entropy shader to address the descriptor-indexed image.

Add a dedicated device-local int16 buffer instead: the entropy shader
writes coefficients into it (one plane per component, MB-aligned coded
size) and the iDCT reads them, so the image is written exactly once, by
the iDCT. The buffer is zero-filled before the entropy dispatch so blocks
with no coded coefficients read as zero, and the decode->iDCT hand-off
becomes a buffer barrier. The output image is still cleared so any padding
the iDCT does not cover stays zero.

avcodec/vulkan_apv: decode VLC codes branchlessly from a single window
apv_read_vlc() dispatched on the three APV code layouts with two data-
dependent branches and, for the long form, a second show/skip. The longest
legal code plus its optional sign bit fits in a single 32-bit window, so
compute all three candidate (value, length) pairs unconditionally and
select with no divergent branches: one show_bits(32) and one skip_bits per
code. apv_read_vlc_sign() additionally folds the trailing sign bit into the
same window, removing the separate get_bit() refill that DC and AC levels
did. Clamps on the long-form length guard corrupt streams without affecting
legal decodes.

avcodec/vulkan_apv: replace the iDCT tile-position search with a division
The iDCT located its tile by linearly scanning the tile column/row start
tables. The APV tile grid is uniform-sized columns and rows with a single
remainder tile at each edge, so the tile index is just the luma position
divided by the (constant) first step, clamped to the last tile. Single
column/row grids have no step to read and resolve to index 0.

avutil/crc: add aarch64 hybrid crc32 NEON PMULL+EOR SIMD implementation
Adding crc32 specialization for aarch64 which uses both PMULL and crc32
instructions to perform 192 bytes fold in one iteration, performing
9x PMULL and 6 crc32 in one loop iteration, obtaining higher performance for
large inputs >8kB. This approach is based on zlib-ng implementation which
is also described at https://github.com/corsix/fast-crc32.

For smaller buffer size, it was observed to be slightly slower, thus only
for input size >8192 this logic is used, for smaller sizes otherwise the
4x PMULL folding method is used along with scalar crc32 instructions for
processing the remainder input size.

On a MediaTek Dimensity 9400 Android device in termux environment,
with normal checkasm seed 0 which picks random buffer size and max buffer size
of 16kB, the data observed on Cortex X925, A720 and X4:
X925 Before:
  crc_32_IEEE_LE_c:                  12762.0
  crc_32_IEEE_LE_crc:                  667.5 (19.11x)
  crc_32_IEEE_LE_pmull_eor3:           346.9 (26.30x)
X925 After:
  crc_32_IEEE_LE_c:                  12707.6
  crc_32_IEEE_LE_crc:                  665.2 (19.10x)
  crc_32_IEEE_LE_pmull_eor3:           292.8 (41.90x)

A720 Before:
  crc_32_IEEE_LE_c:                  23059.1
  crc_32_IEEE_LE_crc:                 1220.7 (18.89x)
  crc_32_IEEE_LE_pmull_eor3:          1198.9 (19.23x)
A720 After:
  crc_32_IEEE_LE_c:                  23293.3
  crc_32_IEEE_LE_crc:                 1209.1 (19.26x)
  crc_32_IEEE_LE_pmull_eor3:          1150.4 (20.24x)

X4 Before:
  crc_32_IEEE_LE_c:                  12405.5
  crc_32_IEEE_LE_crc:                  664.5 (18.67x)
  crc_32_IEEE_LE_pmull_eor3:           498.1 (24.90x)
X4 After:
  crc_32_IEEE_LE_c:                  12457.2
  crc_32_IEEE_LE_crc:                  665.5 (18.72x)
  crc_32_IEEE_LE_pmull_eor3:           468.8 (26.57x)

So it seems to work well on high performance core like X925, and results in about
20% better performance, while having tiny gains on other cores.

Testing for input size of 160 kB after modifying the checkasm crc test to
have buffer size increased to 160kB and always using full capacity instead of
a random size results in below observations:
X925 Before:
  crc_32_IEEE_LE_c:                 210177.1
  crc_32_IEEE_LE_crc:                10313.7 (20.35x)
  crc_32_IEEE_LE_pmull_eor3:          6580.9 (31.83x)
X925 After:
  crc_32_IEEE_LE_c:                 210869.3
  crc_32_IEEE_LE_crc:                10304.8 (20.36x)
  crc_32_IEEE_LE_pmull_eor3:          3098.5 (68.05x)

A720 Before:
  crc_32_IEEE_LE_c:                 387502.5
  crc_32_IEEE_LE_crc:                19196.7 (19.54x)
  crc_32_IEEE_LE_pmull_eor3:         18717.1 (20.63x)
A720 After:
  crc_32_IEEE_LE_c:                 392090.8
  crc_32_IEEE_LE_crc:                19795.1 (18.68x)
  crc_32_IEEE_LE_pmull_eor3:         14971.4 (24.97x)

X4 Before:
  crc_32_IEEE_LE_c:                 196232.0
  crc_32_IEEE_LE_crc:                10378.7 (18.68x)
  crc_32_IEEE_LE_pmull_eor3:          7742.0 (25.29x)
X4 After:
  crc_32_IEEE_LE_c:                 199632.9
  crc_32_IEEE_LE_crc:                10495.8 (18.32x)
  crc_32_IEEE_LE_pmull_eor3:          5448.9 (24.69x)

Seems to result in about 2x gains on X925, 25% on A70 and 40% on X4.
In general the performance gains depends on the CPU Core and input size,
and this optimization benefits large input size especially on high performance
cores like X925 and Apple M series.

when input buffer size is >= 8192. Thus to ensure sufficient test coverage,
size of the input buffer in the test file is being increased from 8192 to 16384.

avformat/shared: hash cache version into filename
Changing version implies a non-backwards compatible disk layout.
Alternatively, we could detect a version mismatch and delete + rebuild the
cache file, but that's nontrivial to get right because of existing processes
that might be concurrently trying to open the same cache file with the old
version.

Overall, cleaner and safer to just separate them by version.

forgejo/workflows: rebase PR commits onto target branch before running verification
This simulates the state of the repository after the PR is
rebased-and-merged into the target branch and validates the merged
result rather than the PR branch in isolation.

Without this step, CI may run against a stale branch. A PR that merges
cleanly can still fail verification after merging into target because
the target branch may have advanced and changed tests. Conversely, the
Docker image used for the build may no longer work with the old
repository state when testing an old PR branch. This also allows the PR
to be revalidated by simply rerunning CI, without requiring an explicit
rebase.

This change also fails CI early when rebase conflicts are detected. Since
PRs with conflicts cannot be merged, there is no value in running the
remaining verification steps.

This is bit strict as it likely will fail to rebase merge commits,
should they be present in the PR. However, we generally prefer linear
history. It's rebased mostly to avoid search for merge commit in target
branch. While for PR we can ask API how many commit there are and the
parent of that should be merge-base commit, for target branch it's
unknown how deep this common commit is. It would be trivial if we did
full non-shallow clone, but we do shallow and probably want to keep it
this way. This forces us to just replay commits from PR on the tip of
the current target branch. It's fine, this is what we want in the end of
the day.

Incidentally this also fixes recently merged
dd6ae3e02412021e016983cc52c242c35e2d7ab1, which tries to validate commit
messages, but by default clone depth is 1 so only single commit message
of head commit in PR was merged. After this change all commits will be
visible. However, I still liked the API script that we had before, not
sure why this was completely reworked.

.forgejo/actions/rebase-pr: workaround stale `forge.event.pull_request.merge_base` value
Unfortunately, Forgejo does not update the merge-base when PR branch is
updated, the `forge.event.pull_request.merge_base` is stale value, from
the time when PR was created. We cannot relly on it, so try to infer
parent commmit of the PR from the shallow clone that we have.

This can be reproduced by:
1. `git rebase X` where X is some commit on target branch, later known
   as merge-base
2. Create PR. Notice that `forge.event.pull_request.merge_base` == `X`
3. `git rebase X^`
4. Force push the reparented branch. Notice that
   forge.event.pull_request.merge_base == X. This is invalid! X not only
   is no longer a merge-base, but it is completelly unrelated commit,
   which exists only on `target` branch, not on PR branch.
5. ????

Additionally I can say that in fact Forgejo does update the merge-base
value, but it looks like it does that AFTER the actions are run, or
maybe concurrently and there is a race there. I've observed that on 2nd
push of a PR branch, rebased on the same parent/merge-base, the reported
value is actually correct, but we cannot rely on that, because on 1st
run it's incorrect if PR branch was rebased on different parent.

For more complex PR fallback to full unshallow and merge.

While at it make git fetches verbose, so we know which commits are asked
for.

avcodec/x86/me_cmp: Improve median_sad functions
The median_abs functions involve computing a predictor
for a pixel difference; deviations from this predicted
pixel difference are summed to the result. For the leftmost
element of a row, the predictor is simply the leftmost
element of the last row (if any; otherwise zero).
For the other elements, it is the median of top, left
and (top + left - topleft).

The current approach to deal with this is to treat
the first element specially (by using a special accumulator
just for it and mask at the end). But there is a better way:
If the left and topleft predictors are zero, the median prediction
is top and therefore yields the correct result for the leftmost
element, obviating the need for the special case.

Creating the registers with zeroed left predictors is easy:
Just shift in the other direction to how it is done now.

Old benchmarks:
  median_sad_0_c:            429.9
  median_sad_0_ssse3:         43.7 ( 9.83x)
  median_sad_1_c:            189.9
  median_sad_1_ssse3:         24.5 ( 7.75x)

New benchmarks:
  median_sad_0_c:            431.1
  median_sad_0_ssse3:         39.7 (10.84x)
  median_sad_1_c:            190.6
  median_sad_1_ssse3:         20.4 ( 9.36x)

avcodec/x86/me_cmp: Reduce amount of registers used
One can avoid one scratch register in MEDIAN_ABS_ACC
(by clobbering topleft which isn't needed lateron).
Furthermore, the earlier code requested more registers
in cglobal than it actually used: median_sad8 only needs
seven registers, median_sad16 only 11. One of these
registers is actually unclobbered (read-only), so
median_sad8 does not need to save and restore and
non-volatile registers on Win64.

Furthermore, the restriction of median_sad8 to x64 can now
be lifted.

libavformat/img2enc: add update_filemtime option
Add a new boolean option -update_filemtime to the image2 muxer that
sets each output file's modification time based on the creation_time
metadata plus the frame's PTS offset.

This is useful when extracting frames from dashcam or action camera
footage where wall-clock timestamps should be preserved on the output
files, allowing photo management tools to sort frames by capture time
without post-processing.

The option requires creation_time metadata to be set (via -metadata
creation_time=...). If not present, a warning is logged and the
option is silently disabled. When PTS is unavailable, the creation
time is used as-is without frame offset.

Uses utimes() on POSIX and _utime() on Windows to set file timestamps
with microsecond and second precision respectively.

Includes a FATE roundtrip test that writes frames with a known
creation_time, reads them back using the demuxer's -ts_from_file
option, and verifies the PTS values match the expected timestamps.

avdevice/avfoundation: wait for frame consumption to avoid dropping A/V frames
The capture callback dropped the previous frame instead of waiting for it
to be consumed, so frames were lost when avf_read_packet() fell behind;
39fbd06314 (return EAGAIN instead of waiting) made it easy to hit.

Add back a condition variable: the capture callback blocks until
avf_read_packet() takes the current frame, and the reader waits on it when
no frame is ready. An is_stopping flag set in destroy_context() wakes both
sides so teardown cannot deadlock. observed_quit is now set under the lock
and broadcast as well, so a blocked reader wakes and returns EOF when a
transport-control device stops delivering frames.

Based on a patch by Zhongxin Zhuang <zx.zhuang@hotmail.com>; here
unlock_frames() only broadcasts and unlocks, so a read no longer releases
the other stream's still-unconsumed frame.

Verified by capturing camera+mic for 8s and comparing delivered packet
counts before/after this change:

  ffmpeg -f avfoundation -pixel_format nv12 -framerate 30 -i "0:0" -t 8 \
         -vf "scale=2560:1440,hqdn3d" -c:v libx264 -preset medium \
         -c:a aac out.mp4
  ffprobe -count_packets -show_entries stream=nb_read_packets out.mp4

  slow consumer (ideal: video ~240, audio ~375)
                     video   audio
    before (EAGAIN)   174     163   (audio ~57% dropped)
    after  (condvar)  234     376   (no drops)

  fast consumer (-preset ultrafast, no filter)

vf_photosensitivity: scale badness threshold with history size
This commit attempts to address feedback from this filter's users, by
improving the filter's behavior at the start of playback or
immediately after seeking.

In these situations, the history buffer is empty, but because we did
not previously track its size, we were calculating the weighted
average as if the corresponding frames had zero badness. This caused
the filter to behave differently and possibly produce false negatives
when the history was not fully populated.

Address this by instead taking into account the history size when
calculating cumulative badness. To accomplish this:

- Add a history_size field to to PhotosensitivityContext, tracking how
  much of the history buffer is populated.

- Change the semantics of PhotosensitivityContext::badness_threshold.
  Previously, it was premultiplied by the maximum history size. This
  is no longer done, so that we can multiply it to the live
  history_size on the fly instead.

- Calculate the badness threshold on a per-frame basis. The result is
  now stored in a badness_threshold local variable.

This commit only changes the filter's behavior for the first
PhotosensitivityContext::nb_frames (configurable as the "frames"
filter option) frames. For successively filtered frames, the behavior
is unchanged.

vf_photosensitivity: add blend option
This commit attempts to address feedback from this filter's users, by
introducing a new option which controls the amelioration mechanism.

The "blend" option is a factor which is multiplied by the difference
in badness (between the threshold and the currently accumulated
badness). This difference normally controls how much of the next frame
we can let through without making it exceed the badness threshold.

Setting the option to zero effectively puts the filter into a mode
where it always duplicates the last frame (which did not put
accumulated badness over the threshold) instead of attempting to blend
in new frames.  I have received reports that this mode is preferable
to users for some types of media.

fate/filter-video: add photosensitivity blend test
Add a small self-contained lavfi test for the photosensitivity filter's
blend path. The graph produces one black RGB frame followed by two white
RGB frames, then runs:

    photosensitivity=frames=2:threshold=95:blend=0.5

The threshold is chosen so that the first black-to-white transition
barely exceeds the detector limit. A full 8x8 RGB grid transition has
badness 64 * 3 * 255 = 48960, while threshold=95 gives 48640 for the
first checked history window. That forces the filter into the blend
branch without needing any external sample.

With blend=0.5, the runtime factor is 48640 / 48960 * 0.5, or about
0.4967. The fixed-point blender truncates this to an input-frame weight
of 127/256, so blending black toward white produces an RGB component
value of 126. The reference therefore records black, the blended gray
frame, and then the following accepted white frame.

This makes the otherwise cryptic CRCs tie directly to the blend
calculation and history update behavior.

all: Don't discard const through {mem,str,strr}chr
C23 made these generic functions that no longer cast const
away for you, leading to warnings when compiling with C23
and a recent enough toolchain (glibc supports this since 2.43).
This commit fixes all the warnings that can simply be fixed
by adding const, without adding casts.
(the latter excludes parse_forced_key_frames() in ffmpeg_mux_init.c).

fftools/opt_common: fix format string bug in print_program_info
FFMPEG_CONFIGURATION and FFMPEG_VERSION were concatenated into av_log
format strings, so any % in them was interpreted as a conversion
specifier and consumed unrelated varargs, causing undefined behavior
ranging from garbled output to a segfault on `ffmpeg -version`. Pass
both as %s arguments instead.

Fixes issue #23662.

The FFMPEG_CONFIGURATION fix is based on a patch by FinnRG; the

avformat/dashdec: fix integer truncation in calc_max_seg_no()
When computing the segment count for a SegmentTimeline entry with
repeat="-1" (indefinite repeat, typical for live streams), the
expression:

  length_of_each_segment = pls->timelines[i]->duration /
                           pls->fragment_timescale;
  num = c->period_duration / length_of_each_segment;

performs two successive integer divisions.  The first division
truncates toward zero; if the segment duration in timescale ticks
is smaller than the timescale (duration < fragment_timescale),
length_of_each_segment becomes 0, and the second division triggers
a division by zero.

Fix this by using av_rescale(), which computes

  period_duration * fragment_timescale / duration

with 64-bit intermediate precision, avoiding both the truncation
and the zero-division risk.  If duration is 0 (invalid manifest),
explicitly fall back to first_seq_no instead of crashing.

avformat/dashdec: check fragment_timescale before division in refresh_manifest
fix issue: issues/23057 POC4

In refresh_manifest(), when timelines are present, fragment_timescale is
used as the denominator to compute currentTime. If fragment_timescale is
zero (e.g., timescale attribute missing from a crafted manifest with
SegmentTimeline), this results in a division by zero.

Add fragment_timescale > 0 guard to both the video and audio timeline
processing paths to prevent the crash.

avutil/hwcontext_vulkan: reject unsupported semi-planar CUDA imports
Cuda currently only supports packed and single-component planar formats, but
fails to import semi-planer (eg: NV12, P010). Even though there are now
semi-planar cuda array formats, which the latest nvdec can use, these formats
are not used when mapping Vulkan imports. Maybe they'll fix that some day.

But until then, let's explicitly detect the case and return a clear error
message for the user.

Exercising this error path revealed that vulkan_free_internal() frees
f->internal on a transfer error and then runs again when the frame is
destroyed, dereferencing the freed pointer; let's make it idempotent.

avfilter/vf_libplacebo: add flag to inherit the input's Vulkan device
vf_libplacebo is unique in that it can function as both a Vulkan filter, and a
software filter, depending on how it the filter graph is configured. While this
is very flexible, it create a problem in situations where the filter does not
receive a Vulkan hw frames context up front. When that doesn't happen, it will
initialise its own standalone pl context, and then fail to interoperate with
a context provided via the input link. This then leads to graph failures.

There are two primary scenarios where this existing logic breaks what should
be valid configurations:
* When the global filter hw device is a cuda device and we use something like
  `hwupload=derive_device=vulkan` to pass frames from cuda to vulkan
* In mpv (and probably other media players) which don't set the global filter
  hw device at all. In this case, it's impossible to configure vf_libplacebo
  to use a hw frames ctx, even if it's using Vulkan for everythng else. This
  prevents the use of vf_libplacebo in any fully hardware accelerated pipeline
  in mpv

There are various ways we could imagine addressing it - such as allowing the
filter to discard the initial pl context and recreating it based on the passed
in device, but it's easier to reason about if we add a flag that explicitly
tells the filter that it should inherit the device context from the input link.
This puts the filter into a mode that works like all the other Vulkan filters.

This requires explicit configuration from the user, but the intent is clearer,
and the user can always know when it's necessary as they define the filter
graph.

avutil/hwcontext_vulkan: query the actual image format in try_export_flags
GetPhysicalDeviceImageFormatProperties2() must be queried with the format
that will actually be used to create the image, otherwise the external
memory export capability check answers for a different format than the one
being allocated.

When AV_VK_FRAME_FLAG_DISABLE_MULTIPLANE is set (e.g. by ffplay for CUDA
interop), vulkan_frames_init selects the per-plane fallback format via
vkfmt_from_pixfmt2(disable_multiplane=1) and stores it in hwctx->format[].
The image is then created with that fallback format. Querying the
multiplane vkf instead returns capability for a format that is never
instantiated, and on NVIDIA GPUs with OPTIMAL tiling the answer differs
between the two formats, producing broken CUDA hwaccel output.

Read hwctx->format[0], which is populated by vulkan_frames_init before
vulkan_pool_alloc runs, so the query matches the image regardless of
whether the multiplane or fallback path was taken.

Fix artifacts with `ffplay -hwaccel cuda foo.mp4`.

avutil/hwcontext_vulkan: declare cuda as a transfer-compatible format
The cuda hwcontext has listed AV_PIX_FMT_VULKAN among its supported
formats since Vulkan interop was first added, so a device's frame
constraints advertise Vulkan as a transfer-compatible ("sw") format.
This is what allows an hwupload targeting a cuda device to accept a
Vulkan frame as input during format negotiation.

The Vulkan hwcontext never made the reciprocal declaration, so an
hwupload targeting a Vulkan device would not accept a cuda frame, and a
cuda -> Vulkan upload could not be configured even though the transfer
itself is supported. Advertise AV_PIX_FMT_CUDA in the Vulkan frame
constraints to ensure we have consistent behaviour in both directions.

avformat/wavdec: move ID3v2 auto-parsing flag from w64 to wav
9d037c54f2 (avformat/demux: avoid unconditional ID3v2 tag consumption)
introduced FF_INFMT_FLAG_ID3V2_AUTO to opt formats into generic ID3v2
parsing, but mistakenly set it on ff_w64_demuxer instead of
ff_wav_demuxer (both live in wavdec.c, with w64 at the end of the file).
As a result, WAV files carrying a prepended ID3v2 tag were no longer
parsed generically, while w64 attempted to parse an ID3v2 tag it didn't
need. Move the flag to the wav demuxer, restoring the originally
intended behavior.

apv_decode: call ff_thread_finish_setup()
"[...] decoders with update_thread_context callback have to call
ff_thread_finish_setup() themselves; it is not done implicitly in

Not doing so makes the decoder effectively single-threaded."

lavc/hevcdec: precompute the significance context tables per scan
The significance flag loop looked up scan_x_off/scan_y_off and then
ctx_idx_map for every decoded bin. The composition of the two is
constant per scan type, so precompute the three permuted tables and
index them by scan position directly. The SCAN_HORIZ table is the
original one, horizontal scan order being raster order.

About 2.5% faster single threaded decoding on high bitrate streams.

idct_dc reads coeffs[0] only and writes the whole block, so the
clear before residual decoding is not needed on that path. Move it

lavc/hevcdec: decode runs of bypass bins with one integer division
Reading a bypass bin doubles the offset and conditionally subtracts
range << 17, which is one step of a binary long division: a run of n
bins is the quotient of the offset, shifted and refilled upfront, by
range << 17, and the new offset is its remainder. Decisions only
depend on multiples of 2^17, so the reordered refill cannot change
any of them; a quotient overflowing n bits, which needs an offset
closer to the range than the pending low bits can distinguish, falls
back to the serial loop.

Use it for the coefficient sign runs, the Golomb-Rice suffixes and
the unary prefixes, whose length is the number of leading ones of a
quotient peeked without committing the bins past the terminating
zero. Sign bins are equiprobable by construction, so on top of the
saved renormalisation work this removes data dependent branch
mispredictions. About 3% faster single threaded decoding on high
bitrate streams.

lavc/hevcdec: remove data dependent branches from residual decoding
Freshly decoded bins are close to equiprobable, so branching on them
mispredicts half of the time. Apply the coefficient signs and the
clipping with the xor/subtract idiom and FFMIN/FFMAX, store the
significant coefficient positions unconditionally while advancing the
count by the flag value, and derive the greater1 contexts and the
first greater1 index arithmetically from a flag mask. About 7% faster
single threaded decoding on high bitrate streams.

avutil/hwcontext_cuda: fail derive if no CUDA device matches
When CUDA enumeration succeeds but none of the device UUIDs matches the
source Vulkan device, ret still holds zero from the last successful CUDA
call.  The error path therefore uninitializes the destination and returns
success.

av_hwdevice_ctx_create_derived() then returns a CUDA device context without
a CUDA context.  Later frame allocation fails with an unrelated error.

Set ret to AVERROR(ENODEV) for the no-match case, consistent with equivalent
Vulkan and OpenCL device selection failures.

lavc/hevc: Always generate missing refs for foll pictures
Since bc1a3bfd2cbc01ffa386312662af8a014890d861, missing reference
pictures are not replaced with generated pictures unless `-flags
show_corrupt` is used.  For `ST_FOLL`/`LT_FOLL` reference pictures,
however, generation of missing references is required by the spec per
8.3.3.  We should not require the `show_corrupt` flag to be used in
order to be spec-conformant, so this patch removes the `show_corrupt`
behaviour added in bc1a3bfd2cbc01ffa386312662af8a014890d861 for
`ST_FOLL`/`LT_FOLL` references and instead unconditionally generates
reference pictures in these sets when unavailable

avcodec/bsf/dts2pts: chain same-gop nodes instead of collecting into a fixed array
hevc_queue_frame() collected all tree nodes of the current gop into a
fixed nodes[HEVC_MAX_DPB_SIZE * 2] array and asserted the count stayed
within it. For a crafted HEVC stream the tree can hold slightly more
same-gop nodes than that estimate (observed 34 vs 32), tripping the
av_assert0 and aborting. Link the matching nodes into a list through a
next pointer in the node instead; this has no size limit and needs
neither extra passes nor allocation.

avcodec/bsf/dts2pts: fix removal of 2nd field nodes
alloc_and_insert_node() inserts the nodes for 2nd fields with
duration / poc_diff added to the timestamp, but the removal loop
compared all nodes of a frame against the unadjusted first timestamp,
so 2nd field nodes never matched and stayed in the tree until close.
Advance the compared timestamp the same way the insertion does.

avcodec/bsf/dts2pts: evict unconsumable nodes from the poc tree
Each pending packet consumes up to poc_diff tree nodes when it is
output, so the packets in the FIFO can consume at most nb_pending nodes
in total. Frames whose tree lookup misses on output leave their nodes
behind, and damaged or crafted streams can make that happen
indefinitely, growing the tree without limit.

Track the node count and insertion order, keep the leftovers of up to
MAX_DAMAGED_FRAMES frames and beyond that evict the nodes unconsumed
the longest. Timestamps of valid frames are unaffected unless more
frames than that are damaged. No eviction is done at EOF, where nodes
are deliberately kept to regenerate timestamps from.

Of all h264/hevc conformance samples only MR3_TANDBERG_B.264 triggers
evictions, and no sample changes output.

Fixes: unbounded memory growth with damaged streams

avformat/utils: fix ff_mkdir_p() swallowing intermediate mkdir errors
When creating nested directories (e.g. /a/b/c), a genuine mkdir()
failure for an intermediate component was overwritten by later
attempts, making the original failure harder to diagnose.

Stop immediately on intermediate errors other than EEXIST, preserving
errno for the caller. Existing path components remain non-fatal, as
required by mkdir -p semantics. Add a regression test for creating a
child below an existing parent directory.

avformat/network: make ff_network_init() follow standard AVERROR convention
ff_network_init() used to return 0 on failure and 1 on success,
requiring callers to check !ff_network_init(). Change it to return
a negative AVERROR(EIO) on failure and 0 on success, matching the
standard FFmpeg convention where negative values indicate errors.

Update all callers (avio.c, rtsp.c, rtspdec.c, sapdec.c, sapenc.c,
utils.c) to use the standard (ret = ff_network_init()) < 0 pattern.

vulkan: fix u32vec2buf/u32vec4buf alignment values
We were optimistic, looking through the GLSL specs, it was illegal to use
an alignment value which satisfied scalar alignment when doing vector loads.
At best, the GPU compiler split it up into multiple parts.

ffv1enc_vulkan: fix VRAM size detection
The reduction accumulated into the zero-initialized context field
instead of the local variable, so the detected VRAM was whatever
device-local heap the implementation listed last, usually the
256MiB BAR heap rather than the multi-GiB VRAM heap.

This made the encoder take the host-memory fallback (or fail the
allocation outright at 12K and above) on hardware with plenty of VRAM.

vulkan/seg_gather: avoid scratch spills and serial prefix summing
Compilers lowered the funnel indexer to scratch (spilling the data),
during the tight copy loop into something that spills every load.
Just use a case to select from the 2 source vectors.

Summing the offsets at the end took far longer than expected and
blocked all invocs. Just use a trivial subgroup add + atomic add
to finish the sum quickly and with less contention.

ffv1enc_vulkan: gather into VRAM and then copy, drop the host-only path
The gather shader wrote the finished bitstream directly into a
host visible buffer with BDA stores.

Keep the gather output in VRAM and append a single copy-engine
transfer to the same submission to move it into the host-visible
readback buffer. DMA readback into cached system memory is the one
path every driver optimizes. Still no CPU involvement.

The host path was awfully slow and only really used because of FFv1's
insane overallocation.

avcodec/x86/vp9lpf: Combine comparisons
The VP9 loop filter involves comparing several unsigned
values against the same value and combines the results:
a <= I && b <= I && ...
This is equivalent to max(a,b,...) <= I and using this
form is beneficial: Each comparison needs one pxor*
and one pcmpgtb and every comparison except the first
uses one por to combine the result. Switching to max
instead results in one comparison and (operands - 1)
pmaxub to create the maximum; the latter can be relaxed
to por if the final comparator is one**, as it is for
flat8{in,out}.

Doing so saves 4113B of .text here and is beneficial
for performance:

avcodec/x86/vp9lpf: Don't do work twice
max(abs(p1-p0),abs(q1-q0)) is currently computed twice.
Stop doing so. This saves 1681B of .text and gives
a small performance boost.

avcodec/x86/vp9lpf: Improve deriving masks
Deriving the fm, flat8in and flat8out masks involves
calculating max{abs(a_i-a), 1<=i<=N} (with N being two or four).
The current code does this by calculating the abs individually
(two psubusb and a por), followed by combining the results
(another por or pmaxub). But there is a better way:
Calculate the min m and max M of the a_i. Then the result equals
max{(M-a)^+,(a-m)^+}, which can be calculated with two
psubusb, followed by combining the result. E.g. for N=2
this saves two por and exchanges two psubusb with pmaxub/pminub.

Doing so saves 2062B of .text here; performance is basically
flat (the length of the critical section is unchanged).

avcodec/x86/vp9lpf: Combine filter2 and filter4 cases
There are two differences between the filter2 and filter4 case.
The first one is

if (hev) {
    int f = av_clip_intp2(p1 - q1, BIT_DEPTH - 1);
    f = av_clip_intp2(3 * (q0 - p0) + f, BIT_DEPTH - 1);
...
} else {
    int f = av_clip_intp2(3 * (q0 - p0), BIT_DEPTH - 1);
...

which can simply be combined to

int f = hev ? av_clip_intp2(p1 - q1, BIT_DEPTH - 1) : 0;
f = av_clip_intp2(3 * (q0 - p0) + f, BIT_DEPTH - 1);

which boils down to masking f by hev after the first
av_clip_intp2().

The second is that two more rows are processed for filter4(),
but one can simply mask the differential there, too.

So one can just combine both filters into one; doing so saves
8457B of .text here and improves performance.

swscale/vulkan: fix invalid SPIR-V generation for plane-remapped passes
The CLEAR codegen iterated components by value[i].den, while the
constants pass iterates by clear.mask; unmasked components may hold
leftover values with a nonzero denominator, consuming more constant
IDs than were registered and emitting ID 0 into the instruction
stream.

The image handle arrays were also sized by the number of planes an
op touches, but plane_src/plane_dst contain actual frame plane
indices, so a pass writing only e.g. the alpha plane references
handle 3 while only handle 0 was loaded.

Either results in invalid SPIR-V, which crashes RADV inside
spirv_to_nir when creating the shader object.

vulkan_encode: destroy image views of queued pictures on uninit
ff_hw_base_encode_close() frees any pictures still in the encode
queue without invoking the encoder's free callback, leaking their
image views when an encoder is closed without fully draining it.
Also uninit the packet buffer pool before the base encode context,
rather than after.

GetEncodedVideoSessionParametersKHR error paths returned err, which
is always 0 at that point, reporting success on failure.

avfilter: add latticepal filter
Convert packed 24/32-bit RGB/BGR/RGBA/BGRA input to PAL8 using a per-frame palette
whose colors are placed on a face-centered cubic lattice (realized as the
scaled D3/D4 checkerboard lattice), with a user-supplied density controlling
the number of lattice steps spanning one color axis.

Only lattice points actually used by a frame enter its palette; if a frame
needs more than 256 of them, the filter will itearatively drop palettte
entries and reassign affected pixels until 256 color remain

lookup uses the Conway-Sloane rounding algorithm. Supported dithering
modes: none, ordered 8x8 bayer (swscale), Cluster & Void blue noise and
Floyd-Steinberg error diffusion.

swscale/x86/ops: avoid direct reliance on `ops` metadata
Instead, use the new metadata introduced in the previous commit. The
motivating reason here is a desire to stop taking a direct SwsOpList from
the backends altogether.

In theory, we could still recover this information from the `uops` list
itself, but that would require far more boilerplate than simply having
uops.c generate it using existing SwsOpsList helpers.

swscale/ops_dispatch: add SwsOpBackend.compile_uops()
This can be used as an alternative to the existing compile() backend, that
takes SwsUOpList instead of SwsOpList.

Down the line, I plan on also moving the uops translation to the dispatch
layer itself, but this requires some further changes which have not yet
been merged, so this commit represents a stopgap solution.

swscale/uops: consolidate SWS_UOP_{PERMUTE,COPY,MOVE}
Rather than having two uops for the C reference code and a separate
uop for the x86 backend, we can just implement the C reference
using the same register-register assignment logic.

This results in only slightly worse codegen, since the compiler is
smart enough to eliminate the unnecessary copies.

The main downside is the fact that we need to allocate extra stack space
to back-fill the remaining (unused) pointers. In theory, we could do this
more efficiently by re-using unused *input* registers directly, but that
would require a lot of reliance on compile-time constant folding teasing
apart the entire register index tracking loop and duplicate check, so this
is a useful middle ground.

On platforms like x86, we still don't care about the PERMUTE vs
COPY distinction, but it's also harmless (2-3 extra lines to
instantiate the underlying MOVE macro on both uop variants).

Finally, we need to add a mask to the move uops to keep track of which
outputs are actually needed (especially for checkasm). Though it does result
in the rather unfortunate downside that it bloats the names of the uop
names.

The op lists change to reflect the new representation, e.g.:

 rgb24 16x16 -> bgr24 16x16:
   [ u8 +++X] SWS_OP_READ         : 3 elem(s) packed >> 0
     min: {0 0 0 _}, max: {255 255 255 _}
   [ u8 +++X] SWS_OP_SWIZZLE      : 2103
     min: {0 0 0 _}, max: {255 255 255 _}
   [ u8 XXXX] SWS_OP_WRITE        : 3 elem(s) packed >> 0
     ('X' unused, 'z' byteswapped, '=' copied, '$' const, '+' integer, '0' zero)
  translated micro-ops:
     u8_read_packed_xyz
-    u8_permute_zyxw
+    u8_permute_xyzw_txz_xzt
     u8_write_packed_xyz

swscale/tests/sws_ops: rewrite to test uops directly
Instead of awkwardly reverse-engineering each uop to reflect
it back to the corresponding SwsOp, this leverages the new
compile_uops() API to directly test the uop in question.

This is not only vastly simpler but also fixes several major
shortcomings with the previous design, such as always having
to keep the reflection code in sync for any newly added uop,
or not testing uops that get translated to a packed shuffle
fast path.

The major downside is that arch-specific uops can now no longer
be tested against the C reference unless we specifically add
a C reference function for each relevant uop; and also, that the
packed shuffle fast path is currently no longer tested by checkasm.
(But this will be fixed by my upcoming pshufb uop series)

Another downside is that this effectively disables testing for e.g.
aarch64, since it does not yet use the uops architecture.

$ time checkasm --test=sw_ops --repeat=10 # 1.85s -> 1.39s

avformat/mov: Add itut-t35 data codec support
The specification for the T35MetaDataSampleEntry ('it35') box is
available in the "Draft text of ISO/IEC 14496-12 10th edition"
which can be found on the MPEG website:
https://www.mpeg.org/standards/MPEG-4/12/

Support the t35 track in mov and export the `t35_identifier`
as extradata and human readable sample description as the stream
description.

avutil/pixfmt: add AV_PIX_FMT_CUARRAY for opaque CUDA block-linear surfaces
Add a new hardware pixel format representing opaque block-linear CUDA
arrays (CUarray). This format is used by NVDEC when decoding into
opaque surfaces registered with cuvidRegisterDecodeSurfaces, and can
be consumed directly by NVENC as CUDA array input without requiring
a pitch-linear copy.

avutil/hwcontext_cuda: add CUarray surface pool support
Extend the internal CUDA frames context (CUDAFramesContext) to manage
block-linear CUarray surfaces alongside the existing pitched-linear
allocations.

When the frames context format is AV_PIX_FMT_CUARRAY, the caller
(e.g. NVDEC) can fill cuarray_desc and cuarray_num_surfaces before
calling av_hwframe_ctx_init(), which then allocates the CUarray
surfaces.

Also add cuda_transfer_data_from_cuarray() to support hwdownload
from CUarray frames to host memory via cuMemcpy2DAsync.

avcodec/nvdec: add opaque CUARRAY output and zero-copy decode support
Add support for NVDEC opaque output using block-linear CUarray surfaces
registered with cuvidRegisterDecodeSurfaces (Video Codec SDK 13.1+).

Two output modes are implemented:

  - Zero-copy (unsafe_output): decode surfaces are exposed directly
    to the consumer (e.g. NVENC). The surface is locked via
    surface_in_use[] and released when the downstream AVBufferRef
    is freed.

  - Safe copy (!unsafe_output): the frame is set up pointing to the
    decode CUarray, then av_frame_make_writable() copies it into a
    new CUarray from the output hwframes pool via cuda_transfer_data().
    This decouples the decode and encode surface lifetimes.

All opaque-specific code is guarded by NVDEC_HAVE_OPAQUE_OUTPUT_SUPPORT,
with a AVERROR(ENOSYS) fallback when building against older SDK versions.

avcodec/cuviddec: add CUARRAY opaque output and zero-copy support
Implement opaque block-linear output for the CUVID decoder, mirroring
the NVDEC hwaccel path but within the standalone CUVID demuxer/decoder.

Key additions:
  - output_format=cuarray option and zero_copy toggle
  - CUarray surface creation and cuvidRegisterDecodeSurfaces
  - Zero-copy path: frames reference decode CUarray surfaces directly
  - Copy path: output surfaces allocated from the hwcontext_cuda pool
  - Deferred decoder cleanup (CuvidDecoderCleanup) to handle the case
    where surfaces outlive the decoder due to encoder buffering
  - 444 chroma sw_pix_fmt remapping to semi-planar (NV24, P410, P412,
    P416) to match the native CUarray layout
  - Per-plane linesize derived from CUarray plane descriptors via
    cuArrayGetPlane / cuArray3DGetDescriptor
  - Crop, resize, and deinterlace forced off (with warnings) for
    cuarray output, as the decode surfaces are used directly

All opaque-specific code is guarded by NVDEC_HAVE_OPAQUE_OUTPUT_SUPPORT.

fftools/ffmpeg_dec: improve hwaccel format negotiation for CUARRAY
Adjust get_format() to prefer the exact hwaccel_output_format requested
by the user when multiple hardware formats are available (e.g. both
AV_PIX_FMT_CUDA and AV_PIX_FMT_CUARRAY). Previously, the loop would
break on the first matching device type, ignoring the user's preferred
output format.

When the preferred format is not available, the code now falls back
gracefully and emits a warning.

avfilter/hwupload_cuda: add CUARRAY output and semi-planar 444 format support
Add an output_format option (cuda | cuarray) so the filter can produce
either pitched-linear (AV_PIX_FMT_CUDA, default) or block-linear
(AV_PIX_FMT_CUARRAY) device frames.  This enables host-to-device
upload directly into CUarray surfaces for the CUARRAY transcode
pipeline.

Also extend the accepted input pixel format list with semi-planar 444
formats (NV24, P410, P416) and the planar MSB variants (YUV444P10MSB,
YUV444P12MSB).  Semi-planar 444 formats are rejected with a clear
error when output_format=cuda, as they are only supported by the
CUarray allocation path.

configure: gate CUARRAY support on ffnvcodec capabilities
The CUARRAY implementation unconditionally references CUDA array
formats and dynamic-loader entries added in nv-codec-headers 13.1.
This breaks builds with older ffnvcodec versions that configure
still accepts.

Probe for the complete CUARRAY header support and use the result
to disable only CUARRAY hwaccels and code paths. Ordinary CUDA,
NVDEC, NVENC, and hwupload_cuda remain available with older headers.

avdevice/android_camera: fix OOB read in metadata parsing
ACAMERA_SCALER_AVAILABLE_STREAM_CONFIGURATIONS metadata is an
int32[n*4] array (one 4-tuple per stream config: format, width,
height, input/output flag). ACameraMetadata_const_entry.count is the
total number of int32_t elements, not the number of tuples. The loop
bound must be count/4 to avoid iterating past the end of the array.

Similarly, ACAMERA_CONTROL_AE_AVAILABLE_TARGET_FPS_RANGES is an
int32[n*2] array (min/max pairs). The loop bound must be count/2.

Without this fix, both loops over-iterate and read heap memory
beyond the metadata array bounds.

avcodec/h264: Ensure that private HW data is freed early for pictures.
Vulkan video decode holds a reference to a VkSemaphore that is waited on
in ff_vk_decode_free_frame.
The bug manifests when a H264 stream changes resolution (or similar)
where the stream needs to be reset in-flight.
In this case, the wait_semaphores call ends up waiting on a destroyed
semaphore, leading to segfaults in drivers. FFVulkanDecodePicture does
not hold an owning reference to the semaphore, so destruction order
matters in this case.

Vulkan validation flags the error as waiting on an invalid semaphore.

swscale/uops: move some simple functions to header file
So that they may be used without uops.c.

This will be useful for aarch64/ops_asmgen.c which is built for the
host system, and not the target system.

avcodec/d3d12va_encode_av1: add user-configurable tile support
Add a "tiles" option (WxH format) to the D3D12VA AV1 encoder. When unset, the encoder falls
back to the minimum number of tile columns/rows that satisfies AV1 spec constraints.

Multi-tile support is also a prerequisite for 8K encoding.

Example usage:
  # default (minimum tiles, auto-computed):
  ffmpeg -hwaccel d3d12va -hwaccel_output_format d3d12 -i input.mp4 -c:v av1_d3d12va output.mp4
  # 2x2 tile  (4 tiles):
  ffmpeg -hwaccel d3d12va -hwaccel_output_format d3d12 -i input.mp4 -c:v av1_d3d12va -tiles 2x2 output.mp4
  # 4x4 tile - required for 8K (7680x4320):
  ffmpeg -hwaccel d3d12va -hwaccel_output_format d3d12 -i input_8k.mp4 -c:v av1_d3d12va -tiles 4x4 output_8k.mp4

avcodec/nvdec: pass hw format explicitly to frame params
avcodec_get_hw_frames_parameters() may invoke frame_params from an
application's get_format() callback. ff_get_format() clears the current
hwaccel before calling get_format(), so avctx->hwaccel is NULL at that
point.

The CUARRAY frame-parameter path dereferenced avctx->hwaccel to
distinguish CUDA from CUARRAY, causing callers such as mpv to crash.
Add per-variant callbacks that pass the registered pixel format
explicitly instead.

Fixes issue #23826.

arm: Avoid warnings about redefining HWCAP constants
Before ced4a6ebc9e7cd92d0ca9b9fb8f9d1013d23cbfa, we used constants
in the form HWCAP_NEON. In that commit, they were renamed to
HWCAP_ARM_NEON, to match the pattern used for aarch64 and PPC.

On PPC our naming is entirely custom to us, upstream headers
(from e.g. glibc) use an entirely different naming.

On aarch64, we use names similar to the system headers, where they
are named e.g. HWCAP_CRC32, but we add an extra prefix, naming them
HWCAP_AARCH64_CRC32, to avoid any potential conflict and redefinition
issues. (In practice, this isn't needed - both glibc, musl and
BSDs provide the aarch64 HWCAP_ defines with the same names and
same literal expansion.)

However, on ARM, the landscape of the HWCAP defines is much less
consistent. On glibc, <bits/hwcap.h> (which gets included by
<sys/auxv.h>) provides most constants with an HWCAP_ARM_ prefix.
(The couple newest constants lack that prefix though.)
The kernel headers, in <asm/hwcap.h>) define them with just a
HWCAP_ prefix, i.e. HWCAP_ARM_NEON vs HWCAP_NEON.

For the actual expansion, <asm/hwcap.h> defines HWCAP_NEON as
(1 << 12), while glibc <bits/hwcap.h> defines HWCAP_ARM_NEON
as 4096. Musl's <bits/hwcap.h> defines both HWCAP_NEON and
HWCAP_ARM_NEON, as (1 << 12).

The BSDs define HWCAP_NEON in <elf.h>, defined as 0x00001000.

Thus, all system headers define the constant with differing
expansions. And they differ in which name they expose for the
constants. But we provide our definitions in any case.

Due to all this, wrap our definitions in #ifndefs, to avoid warnings
about redefining the constants on glibc.

swscale/uops: add SWS_UOP_RW_SHUFFLE
This directly encodes the "pshufb" loop style processing seen in the x86
backend (and, presumably, other backends down the line). The major
advantage of encoding this as a separate UOP is that it allows the macro
generator to exhaustively enumerate all needed variants of the read/write
chunk sizes, which so-far have been hand-maintained through trial and error.

I decided to also go ahead and pre-emptively generalize the clear
value to allow us to encode RGBA clears in addition to RGB0 clears,
which makes this UOP useful for e.g. Gray -> RGBA32 as well; something
that the current pshufb loop did not handle.

This commit merely adds the UOP defition; it does not yet port
the packed shuffle solver or x86 implementation.

swscale/uops: add SWS_UOP_FLAG_PSHUFB
Exposes the SWS_UOP_RW_SHUFFLE capability. While this translates
to the exact `pshufb` instruction on x86, we don't expose a separate
capability for e.g. `vpermb` on AVX-512, since the underlying semantics
are essentially equivalent.

swscale/uops: add ff_sws_shuffle_mask() helper
This takes an arbitrary shuffle mask and expands it out to the needed number
of bytes by repeating pixels.

I decided to have the implementation live in ops_optimizer.c to locate
it closer to the code where these shuffle masks are generated, to aid
in understanding, and because the optimizer will itself use it (in the
following commit).

swscale/uops: rewrite ff_sws_solve_shuffle() in terms of uops
This allows the uop optimizer stage to directly generate RW_SHUFFLE
uops, which will replace the original ff_sws_solve_shuffle() over the next
couple of commits.

This way of solving it has a number of additional upsides, including but not
limited to:

- The ability to move certain low-level optimizations (like expanding
  conversions) out of the higher-level abstraction and have them arise
  purely during uops translation / optimization

- The ability to stop passing SwsOpList to backends at all

swscale/x86/ops: rewrite packed_shuffle() in terms of uops macro
This is mostly the same, with the added complication of now needing to handle
the case of clearing to a nonzero value, which we do using `pblendb` on SSE4,
and respectively `vpblendb` / `vpblendmb` on AVX-2 and AVX-512.

Since `pblendb` hard-codes XMM0 implicitly, we have to flip the order of `m0`
and `m1` in the rest of the code as well; though that's not a huge deal.

The bigger complication comes from the fact that the macro gives us the size
for a size 16 mask, which may need to be rounded up for the lane-aligned
AVX-2 / AVX-512 paths, so we need to recreate this logic in the NASM macro
itself. Fortunately, it's fairly straightforward.

The big upside is that we now gain a fast path for e.g. rgb24 -> rgba, which
is arguably more common than rgb24 -> rgb0:

  rgb24 1920x1080 -> rgba 1920x1080, speedup=7.106x faster

It's worth pointing out that, because checkasm sometimes generates weird ops
that don't occur in real pixel formats, it's not a guarantee that we will
actually implement all paths that the optimizer spits out.

This should be improved by a future checkasm refactor; but for now, we need
to return ENOTSUP in the case that we encounter a shuffle mask combination
that doesn't actually exist. (In practice, this only happens for degenerate
no-op tests like 1->1 shuffles)

swscale/x86/ops: add AVX512 vpermb packed shuffle path
We can quite easily generalize the existing AVX512 pushfb implementation to
support vpermb when the shuffle mask is cross-lane.

  rgb24 1920x1080 -> rgba 1920x1080, speedup=1.372x faster

This does require some finesse w.r.t. the MOVSIZE macro, to avoid reading or
writing too many bits. In particular, for gray->rgba64le, the pattern even
devolves into 8/64 which would trigger an illegal operand error when combining
movq with zmm registers.

Other than that, we can use {k1}{z} zero masking to cleanly recreate the
semantics of pushfb's implicit zero masking, except for non-zero clear
values where we continue doing what we already do.

Lastly, while EVEX-encoded vpermb can take the source operand directly, this
somewhat defeats the purpose of the READ size optimization; in practice it
was better to keep the read and vpermb separate.

avfilter/dnn: implement batching for Torch backend
Add batch processing support to the LibTorch DNN backend, following
the same pattern used by the OpenVINO backend.

Key changes:
- Add batch_size AVOption (range 1-1000, default 1) to DnnContext
- Accumulate lltasks in the queue, trigger inference when batch_size
  lltasks are ready (matching the OpenVINO batch execution pattern)
- Pre-allocate a single contiguous memory buffer for the entire batch
  in fill_model_input_th() to avoid unnecessary tensor copies
- Split batched output in infer_completion_callback() and dispatch
  each slice to its corresponding task

Tested with:
ffmpeg -f lavfi -i testsrc=duration=5:size=640x480:rate=25 -vf format=rgb24,dnn_processing=dnn_backend=torch:model=dummy_model.pt:batch_size=4 -f null -

lavf/oggparsevorbis: rework timestamp offset and end trimming
Replace the first-page packet scan with a direct use of the first
packet's duration as the timestamp offset (the Vorbis I spec
guarantees it produces no PCM output).

Track last_page_granule to correctly anchor EOS trimming regardless
of any initial granule offset. Track bos_pos to reinitialize parser
state at stream boundaries without resetting at page boundaries.

Restore the granule=0 workaround from ticket #3710 and handle
chained streams by clearing bos_pos when new headers are collected.

configure/x86: test 6- and 7-register inline asm
HAVE_6REGS and HAVE_7REGS should describe whether the compiler can
allocate the inline asm register sets they guard. The old x86-32 logic
inferred that from EBX/EBP availability, while x86-64 enabled both
macros without a configure test.

Probe the 6- and 7-register asm constraints directly for all x86 targets
and let asm.h use the configure results. Drop the EBP availability
probe, which is no longer used. Keep EBX availability, as other inline
asm still uses it to decide whether named EBX can be clobbered.

avformat/tls_mbedtls: check the certificate verification result in tls_handshake()
tls_mbedtls verifies the peer certificate manually via
mbedtls_ssl_get_verify_result() (it uses MBEDTLS_SSL_VERIFY_OPTIONAL), but
only in tls_open(). On the external-socket path (external_sock=1) tls_open()
skips the handshake; it then runs later through the url_handshake hook,
tls_handshake(), which never checks the verification result, so with verify=1
an untrusted peer certificate would be accepted.

The only in-tree user of this path is the WHIP muxer, which sets verify=0
(WebRTC binds the peer via the SDP a=fingerprint, not a CA), so this is not
reachable today. This change is defence-in-depth: it makes tls_handshake()
honor verify symmetrically with the existing tls_open() check.

avformat/shared: use strong CAS for marking PENDING
This was using a weak atomic under the assumption that the `goto retry`
will immediately jump back to the same line. However, that's no longer
true after the introduction of the `read_block` label, which we can
jump to from the error handling fallback path.

In this case, we really ought to use a strong CAS to ensure that we
only re-check the state if it truly changed in the meantime.

avcodec/psymodel: add pair-synced window switching hook and pair state
Divergent block switching between the two channels of a CPE disables
common_window, and with it every joint stereo tool, on exactly the
frames that need them most; the lone short channel then codes its
transient alone, which is audible as one-channel garble at beats.

Add an optional window_pair() model hook so a psy model can decide both
channels of a pair together, and encoder-fed per-pair state: the
joint-tool candidacy fraction EMA and a Schmitt-gated decouple flag,
letting the model fall back to independent per-channel switching on
content whose joint tools are dead (diffuse, decorrelated pairs) where
forcing a common grid only costs quality.

avcodec/aacenc: rework NMR rate control, pool CPE budgets, add decision memory
Rate control: replace the integral servo with a stateless pressure
offset (exp2(-K*fill/R)) so a drained reservoir cannot wind up and
crater quality after loud stretches; slew-limit the final operating
lambda per frame (bits deviate instead, the reservoir absorbs); seed
the reservoir full at stream start; and track rate strain explicitly:
a long-frame lambda EMA against anchors that scale up when the achieved
distortion/mask ratio flags noise-class content (whose psy masks are
wholesale violated and lambda reads inflated), plus a lambda min-tracker
separating sustained starvation from transient spikes at a comfortable
operating point. The resulting pressure ramp gates every
pressure-adaptive tool from one place.

CPE budget pooling: solve both channels of a pair jointly under one
shared lambda against a pooled budget (NMRSlot defer/solve/commit)
instead of an equal per-channel split, which starved the mid/carrier
while the side gold-plated. Mono and VBR output are unchanged.

Transients: isolated onsets are coded uniformly finer across the short
run and repaid from steady stretches; dense-beat runs get a
starvation-scaled boost; a transition premask clamps START-frame
thresholds toward the previous long frame (an attack cannot mask
backwards).

Decision memory: marginal per-frame re-decisions oscillate audibly, so
every stateful choice now carries hysteresis - band zeroing, PNS
enter/leave with debounce (and near-masked bands staying noise until a
loudness guard), per-grid stereo mode banks that survive window
switches, and the short-TNS accept state.

TNS-covered bands price distortion by the synthesis filter's
re-amplification gain, so the trellis spends where noise will actually
be heard.

avcodec/aaccoder: widen PNS candidacy to near-masked bands
Bands whose energy sits between threshold/4 and 2x threshold are
deletion candidates for the trellis: coded, they round to silence under
pressure, and an audible hole is worse than energy-matched noise. Let
them qualify for PNS with a relaxed uniformity requirement, so the
noise substitution keeps the texture the allocator was about to delete.

avcodec/aacenc_tns: enable short-block TNS via pooled per-group filters
Per-window filters combined with group-shared scalefactors made
short-block TNS produce decoder-synthesized silence: a weak residual in
one sub-window rounds to zero under the group's scalefactor and the
synthesis filter has nothing to re-amplify, audible as 1.5-3 ms
dropouts on beat content. Fit ONE filter per window group instead, on
the concatenated weighted spectra, and require every window in the
group to pass the prediction-gain bar.

Accepts are Schmitt-gated and run-scoped: within a short run the enter
bar is raised and the hold bar lowered (accept flicker was audible as
gravel), while isolated transient frames - where TNS matters most and
cannot flicker - use the base bar.

avcodec/aacpsy: sync block switching across channel pairs
Implement the window_pair() hook: detect both channels of a CPE, then
decide together - if either channel attacks, both switch, with one
merged attack map so the grouping matches across the pair and
common_window survives transients. Pairs the encoder has flagged as
decoupled (joint tools dead) keep independent per-channel decisions,
where forcing the steady channel short at every event in the other
only costs quality.

Attacks must also be NOVEL against the trailing high-pass max-envelope:
a steady pitch-pulse train repeats its peak every period and re-fires
the ratio test forever, producing long false short runs on periodic
content (low brass and the like); a genuine onset towers over the
recent past.

The pre-echo threshold relaxation for gentler isolated onsets is kept,
and START frames entering a short sequence clamp their thresholds
toward the previous long frame's per-band values on the mapped long
grid.

avcodec/aacenc: rework NMR stereo decisions, retune coded bandwidth
Stereo decisions are made per band before quantization, from the psy
model's spectra, and carry cross-frame memory (EMA-smoothed statistics,
per-grid mode banks, leave-hysteresis) so the image holds instead of
churning:

  * M/S adopts content-driven and rate-free (side under half the mid);
    for mid-dominant bands M/S is simply the better coding at every
    rate, and a wandering L/R fraction reads as image instability.
  * I/S competes with M/S above 6.1 kHz instead of only seeing M/S
    rejects (which are exactly the wide bands it cannot render), and
    engages under SUSTAINED strain only: the pressure ramp gated by the
    lambda floor, so pressure spikes at a comfortable operating point
    cannot flood it onto content where coding the side is affordable
    and strictly better. Unengaged candidates fall back to M/S.
  * Pairs whose joint-tool candidacy fraction stays low decouple:
    block switching goes per-channel and M/S stops, matching how
    independent coding wins on diffuse decorrelated content.
  * PNS in a pair is reserved for clearly-wide bands (it renders
    uncorrelated noise per channel).

Block switching for a pair is decided through the psy window_pair()
hook so common_window survives transients.

The NMR rate-to-bandwidth table is retuned upward at >= 48 kbps/ch to
track the bandwidth strong encoders deliver; both quality metrics
improve on a 16-clip battery and wider regresses. Lower rates are
unchanged.

swscale/tests/sws_ops_aarch64: use AVBPrint instead of custom string functions
buf_appendf() was used when this code still needed to run standalone in
aarch64/ops_asmgen. Since this is no longer the case, use AVBPrint
instead.

Also use ff_sws_pixel_type_size() instead of aarch64_pixel_size().

This is a step towards the move to uops.

avcodec/aacpsy: fix the attack lookback
This fixes a 15+ year old bug.

The novelty check read its previous-frame envelope from
prev_energy_subshort after the sub-block loop had already overwritten
it with current-frame values, so early sub-blocks were compared
against the frame's own future instead of the past. That accident
suppressed short-period pitch trains well enough, but also suppressed
genuine onsets, and could not see pulse periods beyond ~12ms at all:
on quiet slow pulse trains (engine-idle buzz and the like) the ratio
test leaks sporadic isolated short excursions, each an audible click -
reported against this encoder since 2015, at every bitrate, and
immune to disabling every coding tool.

Keep a rolling two-frame history of HP sub-block peaks instead and
require an attack to tower over it: within ~12ms unconditionally
(pitch-rate trains), and within ~44ms when coming from steady
long-window state (slow trains, where an isolated short excursion can
only click). Dense irregular transients tower locally and reset
frames_since_short, so their block switching is untouched.

avcodec/vulkan_encode_av1: fix level auto-detection using zero dimensions
Move level guessing from init_profile() to init_sequence_headers(),
where base_ctx->surface_width/height are already initialized.

init_profile() is called from ff_vulkan_encode_init() before the
surface dimensions are set, so ff_av1_guess_level() always received
zeros and selected the lowest level (2.0). init_sequence_headers()
runs after ff_vulkan_encode_init() returns, matching how H.264 and
H.265 Vulkan encoders handle level detection.

avcodec/vulkan_encode_av1: fix level and tier option handling
Copy opts.level into avctx->level (matching H.264/H.265 encoders),
so the -level command line option is actually used. Also initialize
enc->seq_tier from opts.tier so the -tier option takes effect.

The -level option values (0-23) already match the StdVideoAV1Level
enum directly, so assign avctx->level to seq_level_idx without going
through ff_vk_av1_level_to_vk() which expects AV1 spec-style level
numbers (20, 21, 30, ...).

avcodec/pngenc: fix overrun caused by exif size discrepancy
If the estimated EXIF size based on the attached frame data is lower

estimated exif size so there won't be any discrepancy between the two
values.

avutil/hwcontext_cuda: drain queued copies on transfer error
cuda_transfer_data() can enqueue copies for earlier planes before a
later cuArrayGetPlane() or cuMemcpy2DAsync() fails. Returning at that
point can let queued work outlive caller-owned AVFrame buffers.

Track whether a copy was successfully queued and synchronize the stream
on these later failures. Synchronization is best-effort: its errors and
cuCtxPopCurrent() errors stay logged without replacing the primary
failure.

Successful H2D and D2D transfers remain asynchronous, and the normal
host-download synchronization path is unchanged.

avcodec/d3d12va_encode: set extradata for global header when muxing AV1 to MKV
When the muxer sets AV_CODEC_FLAG_GLOBAL_HEADER (as MKV does), the codec
must populate avctx->extradata with the sequence header so the muxer can
write the av1C codec private entry. Otherwise, the mkv muxer will return
AVERROR_INVALIDDATA on the first packet (Invalid data found when
processing input).

Example usage:
  # use mkv container:
  ffmpeg -hwaccel d3d12va -hwaccel_output_format d3d12 -i input.mp4 -c:v av1_d3d12va output.mkv

swscale/aarch64/ops_asmgen: use RasmOp directly when generating masks for SWS_UOP_UNPACK
There is no need to pack the vector register usage for this function.
This change creates holes in the usage of const vector registers, but
populates the RasmOp const array directly, which will help for the
implementation of the JIT compiler.

swscale/aarch64/ops_asmgen: load values from exec before performing setup
This changes little for the current CPS code, which has fairly simple
setup code. But in JIT we will factor out much more code from the main
loop into the setup section.

This also frees up the register used by exec (x0) earlier on, so it may
be reused earlier in JIT code.

swscale/aarch64/ops_asmgen: move save_mask setup out of asmgen_op_linear() and into asmgen_setup_linear()
The save_mask setup makes copies of input data that would be clobbered
by the linear operation itself. This setup is not entirely necessary
with JIT, since we may have separate input and output vector registers,
so the code is moved into the setup function which will be CPS-only.

This doubles the amount of temp registers needed, since they must all
be copied before both loops.

avutil/hwcontext_cuda: remove format allowlist, accept any pixel format
Remove the static supported_formats[] allowlist from hwcontext_cuda.
cuda_frames_get_constraints() now iterates all registered pixel formats
and includes every non-hwaccel, non-palette format. cuda_frames_init()
validates with av_pix_fmt_desc_get() instead of checking against the
allowlist.

Palette formats have a special-cased use of plane[1] for the palette itself
and it's not worth the hassle of supporting in an otherwise clean generic
copy loop.

Also add a roundtrip test that uploads a deterministic byte pattern to
CUDA, downloads it back, and verifies the data match. This tests all
non-hwaccel pixel formats. The test is gated on CONFIG_CUDA.

avcodec/get_buffer: use frame pixel format instead of context
The documentation for get_buffer2() states:

"This callback must use the frame values, not the codec context values, to
calculate the required buffer size."

Fixes wrong output on hbd LCEVC enhanced samples where the base stream is
8bit.

avformat/mov: read DTS metadata from ddts box
The MOV demuxer only handled the low four bits of ChannelLayout and
did not expose the DTS profile carried by StreamConstruction. It also
discarded the sample-entry channel count when ChannelLayout was zero.

Parse StreamConstruction, RepresentationType, and all 16 ChannelLayout
bits according to ETSI TS 102 114. Map StreamConstruction to the
corresponding FFmpeg DTS profile, and preserve the sample-entry channel
count for zero layouts unless RepresentationType explicitly signals two
encoded channels.

This also provides profile and channel metadata for encrypted samples
whose frame headers cannot be inspected.

avfilter/dnn: fix async teardown race condition in all backends
When the filter graph is torn down early (e.g. at EOF with -frames:v),
the main thread calls dnn_free_model and destroys the request queue
while async inference threads may still be running. When a detached
thread finishes and tries to push its result back to the destroyed
queue, it triggers a segmentation fault.

Add ff_dnn_wait_requests() to dnn_backend_common which blocks
until all allocated request items (ctx->nireq) have been safely
returned to the request_queue. Call it from dnn_free_model in the
torch, tensorflow, openvino, and onnx backends before destroying the queue.

avformat/hlsenc: Fix heap buffer overflow in parse_playlist()
Fix: vulnerability:019f3b84-903b-75fb-a8de-fe6f84d6bc32

When parsing IV=0x... followed by a comma, end - ptr was passed directly
to av_strlcpy() as the destination size. Since iv_string is only 33 bytes
(KEYSIZE*2 + 1), a long IV token could overflow into adjacent heap data.

Use FFMIN(end - ptr + 1, sizeof(buf)) to cap the copy size to the actual
buffer size. Apply the same fix to key_uri parsing for consistency.

Fixes a heap buffer overflow in append_list mode when reading an existing
playlist with a crafted IV or URI token length.

avformat/hls: Enforce protocol checks when opening child playlists
Fix: vulnerability:019f3b84-903b-75fb-a8de-fad1c2d7e99c
The parse_playlist() path for opening a new child playlist (in == NULL)
directly called c->ctx->io_open(), bypassing the protocol whitelist and
file-extension checks that open_url() enforces. This allowed child URLs
from a master playlist to use protocols other than file/http/data or to
have disallowed extensions.

Route the !in branch through open_url() so that all child playlists are
subject to the same security policy as segment URLs.

Fixes a security bypass in HLS master playlist parsing.

fix: vulnerability:019f3b84-90fb-737a-ae7a-b3e0219266fc
extract_segment_number() used strrchr(filename, '.') and immediately did
dot - 1 without checking for NULL. A segment URI with no extension would

avformat/spdifenc: preserve TrueHD MAT padding across branches
Some TrueHD streams, particularly remuxes of seamless branching Blu-rays,
contain input_timing gaps that require more padding than the current
MAT_FRAME_SIZE / 2 limit allows.  spdifenc treats this padding as
invalid and drops it, breaking MAT timing and IEC 61937 carrier cadence,
causing TrueHD/Atmos dropouts on some receivers.

Allow larger valid padding gaps and queue completed MAT buffers so the
muxer can preserve the carrier cadence while still writing at most one
MAT buffer per input packet.

Some branches also have discontinuous timing, so input_timing cannot be
directly used to compute padding at those boundaries.  When output_timing
is available from a TrueHD restart header, use it to detect those
discontinuities and compute padding from the change in
output_timing - input_timing offset across the boundary instead.

tests/fate/spdif: add TrueHD branch padding test
Add a small synthetic TrueHD sample that exercises large MAT padding in
spdifenc. The sample covers both the input_timing path with padding above
MAT_FRAME_SIZE / 2 and the output_timing discontinuity path.

It also verifies queued MAT frame emission when one input packet completes
more than one MAT frame.

Revert "avfilter/avfiltergraph: always retry format negotiation after auto-filters"
This reverts commit 978a0821eeb909d7b2cb777bed03a8fc380e9503.

The stability of the negotiation process has never been studied
with multiple rounds.

It has always been documented to users that scale was the filter
to insert to manage format conversions. A second filter for
a specific type of conversion should never have been added:
the proper fix for the issue that this commit tried to fix is
to give scale the ability to handle premultiplication too.

lavfi: do not send premultiplied alpha to filters not ready for it
The arithmetic to process colors in premultiplied alpha is
completely different from the arithmetic for straight alpha.
Running a filter using straight arithmetic on premultiplied
will result in incorrect and sometimes invalid output.
Therefore, premultiplied alpha should only be selected for
filters that either explicitly support it or only use
elementary color arithmetic or none at all.
For other filters, automatic conversion will do its work.

avformat/libcurl: add seek, size and retry
Probe Accept-Ranges/Content-Range/Content-Encoding to determine
seekability and total size, issue ranged requests via CURLOPT_RANGE,
implement url_seek (including AVSEEK_SIZE) as a reconnect at the new
offset, and resume seekable transfers from the next missing byte after a
recoverable error.

Note that we prefer the compression over seekability, as servers are
unlikely to compress media files in practice, as this would be huge
performance cost for zero gain. However downloading text playlists
benefits a lot from compression. YouTube for example can serve text
files that have 30MB+ which is huge bandwidth usage when not compressed.

avformat/libcurl: avoid TOCTOU in libcurl_seek()
If this triggers while an asynchronous header_callback() (e.g. from a previous

be written to while libcurl_seek() is still reading from them.

I'm not convinced this is an actual bug in practice, but tsan at least is
bound to complain about it.

Note that the connection state, DNS cache, SSL session etc. are shared by
default when using a multi handle, so we only need to explicitly share the
rest.

avformat/libcurl: use int64_t consistently
Instead of randomly mixing in uint64_t. As far as I can tell, we don't
depend on defined overflow behavior anywhere, except where such would be a
bug anyways, and I'm also pretty sure we won't exhaust the 63-bit file size
limit of int64_t any time soon, so this is just a footgun prevention
mechanism.

We already have a few dodgy places of mixing int64_t and uint64_t values
in the code haphazardly.

avformat/libcurl: harden against malicious underflow
If the server sends a value of INT64_MIN here, we would correctly parse
it and then subtract off -1, underflowing to a huge positive value
(and triggering undefined behavior in the process).

avformat/libcurl: guard against overflow from over-reading data
In theory a client could be coaxed by a malicious server to seek to a
large 64-bit offset, which would then trigger an overflow of the position.

Better safe than sorry and just error out with EIO in such cases.

tests/checkasm/checkasm: Map rnd to checkasm_rand_uint32
Before the switch to libcheckasm, rnd returned an unsigned value;
now it only returns a signed value in the range 0..INT_MAX,
so that the sign bit is not random at all. This means that when
rnd is used to initialize four bytes at a time, one bit is not random.
Fix this by mapping rnd to checkasm_rand_uint32().

avformat/os_support: fix return value of win32_rename
The return value of MoveFileExW was not being correctly interpreted,
see https://learn.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-movefileexw.

On Windows a failed rename over the file: protocol now surfaces as failed to rename file %s to %s:
Operation not permitted (ff_rename, libavformat/avio.c:867) plus an AVERROR(EPERM) return, where previously the muxer
reported success and the user was left with a missing or stale output file and no diagnostic. This affects the
write-to-temp-then-rename paths in hlsenc, dashenc, hdsenc, smoothstreamingenc, segment, and img2enc (e.g. HLS/DASH
playlist updates, -write_temp_file, segment list finalization).

Also, added unit tests to exercise the rename function.

avcodec: add PCM DVD-Audio decoder
Decodes the LPCM variant found in DVD-Audio AOB streams. Unlike
DVD-Video LPCM it supports up to 192 kHz sample rates and splits
channels in two channel groups, which may use different quantization.
Samples are grouped in sets of 2 samples over all channels, with the
second channel group's data stored first within each set, as 16-bit
big-endian most significant parts followed by the remaining bits.

Based on information from expired US 6,580,671 patent et al.

avformat/mpeg: fix demuxing of DVD-Audio LPCM
Substream 0xa0 packets without the DVD-Video dynamic range control
marker byte were assumed to be MLP, while in DVD-Audio AOBs substream
0xa0 always carries LPCM (MLP uses 0xa1), so hi-res LPCM streams were
misdetected and decoded as garbage. Classify them as PCM_DVDA and keep
the private stream header in the packet for the decoder to parse, as
its length is variable and it carries the audio format.

avformat/hls: allow seeking within live playlists
Live (and EVENT) playlists are seekable within the currently known
segment list. Seeks before the list start clamp to the oldest segment,
past the end to the live edge. Live playlist can evict old segments, we
track that by reading EXT-X-MEDIA-SEQUENCE. Previusly the code assumed
that the live playlist, don't have past segments, however some servers
has very deep usable timeshift.

avformat/hls: set stream start_time for all playlist types
Rebase the first packet's timestamp onto the start of the segment list
regardless of playlist type, and report it as start_time. Previously
only EVENT playlists did this and live streams took start_time from the
first loaded segment at the live edge. Which is not correct as some
servers provide very deep (hours even) time shift in live playlist. The
evicted segments are already tracked by EXT-X-MEDIA-SEQUENCE. This
allows us to use all available segments, not only the future ones on
live playlist.

Also prefer PTS over DTS, as EXTINF durations and start_time are
presentation time.

avformat/hls: don't discard target segment's first keyframe when seeking
Segment starts on the seek timeline are derived from EXTINF durations,
so the first keyframe of the target segment can have a slightly lower
DTS than the snapped seek position, in which case the packet discard
loop would skip it and resume playback one segment late. Make sure we
start at the very beginning of the stream in this case.

avformat/hls: refine first_timestamp from the first segment's packets
first_timestamp is taken from the first packet in mux order, which is
not necessarily the earliest timestamp in the segment. Lower it while
packets of that segment are still arriving, so the seek timeline is
anchored at the true segment start.

avcodec/videotoolboxenc: respect CMTime.timescale when computing timestamps
vtenc_cm_to_avpacket converts output CMSampleBuffer timestamps back
to codec timebase by dividing pts.value by avctx->time_base.num.
This relies on the output CMTime having the same timescale as the
one passed to VTCompressionSessionEncodeFrame. Apple does not
guarantee this, and the output timescale can differ from the input.

Use av_rescale_q with the actual CMTime timescale so that the
conversion is correct regardless of what timescale VideoToolbox
returns.

avfilter/vf_amf_common: fix component Init() format with hwaccel input frames
amf_init_filter_config() returned the hardware pixel format (e.g.
AV_PIX_FMT_D3D11) as in_format when the input link carries D3D11VA or
DXVA2 hw frames. av_av_to_amf_format() maps hw formats to
AMF_SURFACE_UNKNOWN, so every AMF filter failed its component Init()
with AMF_INVALID_ARG (VQEnhancer, FRC) or AMF_NOT_SUPPORTED
(Converter, HQScaler). Return the underlying software format instead,
which is already validated against AMF a few lines above. Apply the
same mapping to the default output sw format, which otherwise ends up
as the hw pixel format in hwframes_out->sw_format when the output link
uses a hwaccel format.

Fixes e.g.:
  ffmpeg -hwaccel d3d11va -hwaccel_output_format d3d11 -i in.mp4          -vf frc_amf -c:v hevc_amf out.mp4

Note: with D3D11VA input, the compute-based components (VQEnhancer,
HQScaler, VideoConverter) additionally require decode textures created
with D3D11_BIND_SHADER_RESOURCE, e.g.:
  -init_hw_device d3d11va=dx11:,SHADER=1 -hwaccel_device dx11
FRC and DXVA2 input work with default decode textures.
