The use of nvcc to compile cuda kernels is distinct from the use of

previously not bothered to distinguish these two cases because all
the filters that used cuda kernels also used the sdk. In the following

The unconventional library check can be explained by the library's

Thus, one either has to wait for the following release, or enable

- Allow to add deps in any order rather than "in linking order".
- Expand deps chains as required rather than just once.
- Validate that there are no cycles.
- Validate that [after expansion] deps are limited to other fflibs.
- Remove expectation for a specific output order of unique().
Previously when adding items to <fflib>_deps, developers were
required to add them in linking order. This can be awkward and
bug-prone, especially when a list is not empty, e.g. when adding
conditional deps.
It also implicitly expected unique() to keep the last instance of
recurring items such that these lists maintain their linking order
after removing duplicate items.
This patch mainly allows to add deps in any order by keeping just
one master list in linking order, and then reordering all the
<fflib>_deps lists to align with the master list order.
This master list is LIBRARY_LIST itself, where otherwise its order
doesn't matter.
The patch also removes a limit where these deps lists were expanded
only once. This could have resulted in incomplete expanded lists,
or forcing devs to add already-deducable deps to avoid this issue.
Note: it is possible to deduce the master list order automatically
from the deps lists, but in this case it's probably not worth the
added complexity, even if minor. Maintaining one list should be OK.

x4 - x25 faster.
check_deps() recursively enables/disables components, and its loop is
iterated nearly 6000 times. It's particularly slow in bash - currently
consuming more than 50% of configure runtime, and about 20% with other
shells.
This commit applies few local optimizations, most effective first:
- Use $1 $2 ... instead of pushvar/popvar, and same at enable_deep*
- Abort early in one notable case - empty deps, to avoid costly no-op.
- Smaller changes which do add up:
- Handle ${cfg}_checking locally instead of via enable[d]/disable
- ${cfg}_checking: test done before inprogress - x2 faster in 50%+
- one eval instead of several at the empty-deps early abort path.
- The "actual work" part is unmodified - just its surroundings.
Biggest speedups (relative and absolute) are observed with bash.

Change it to use sed once on the source file and set env vars with the

Additionally, the cases of indev_list and outdev_list are very
infrequent, but nevertheless they're faster, and arguably cleaner, with

x50 - x200 faster.
Currently configure spends 50-70% of its runtime inside a single
function: flatten_extralibs[_wrapper] - which does string processing.
During its run, nearly 20K command substitutions (subshells) are used,
including its callees unique() and resolve(), which is the reason
for its lengthy run.
This commit avoids all subshells during its execution, speeding it up
by about two orders of magnitude, and reducing the overall configure
runtime by 50-70% .
resolve() is rewritten to avoid subshells, and in unique() and
flatten_extralibs() we "inline" the filter[_out] functionality.
Note that logically, "unique" functionality has more than one possible
output (depending on which of the recurring items is kept). As it
turns out, other parts expect the last recurring item to be kept
(which was the original behavior of uniqie()). This patch preservs
its output order.

Lensfun is a library that applies lens correction to an image using a
database of cameras/lenses (you provide the camera and lens models, and
it uses the corresponding database entry's parameters to apply lens
correction). It is licensed under LGPL3.
The lensfun filter utilizes the lensfun library to apply lens
correction to videos as well as images.
This filter was created out of necessity since I wanted to apply lens
correction to a video and the lenscorrection filter did not work for me.
While this filter requires little info from the user to apply lens
correction, the flaw is that lensfun is intended to be used on indvidual
images. When used on a video, the parameters such as focal length is
constant, so lens correction may fail on videos where the camera's focal
length changes (zooming in or out via zoom lens). To use this filter
correctly on videos where such parameters change, timeline editing may
be used since this filter supports it.
Note that valgrind shows a small memory leak which is not from this
filter but from the lensfun library (memory is allocated when loading
the lensfun database but it somehow isn't deallocated even during
cleanup; it is briefly created in the init function of the filter, and
destroyed before the init function returns). This may have been fixed by
the latest commit in the lensfun repository; the current latest release
of lensfun is almost 3 years ago.
Bi-Linear interpolation is used by default as lanczos interpolation
shows more artifacts in the corrected image in my tests.
The lanczos interpolation is derived from lenstool's implementation of
lanczos interpolation. Lenstool is an app within the lensfun repository
which is licensed under GPL3.

This commit implements a full ATRAC9 decoder, a simple low-delay codec
developed by Sony and used in most PSVita games, some PS3 games and some
PS4 games. Its similar to AAC in that it uses Huffman coded scalefactors
but instead of vector quantization it just Huffman codes the spectral
coefficients (in a way similar to how Opus splits band energy coding
into coarse and fine precision). It opts to write rather large Huffman
codes by packing several small coefficients into one Huffman coded
symbol, though I don't believe this increases efficiency at all.
Band extension implements SBC in a simple way, first it mirrors the
lower spectrum onto the higher frequencies and then it uses one of 5
filters to shape it. Noise substitution is implemented via 2 of them.
Unlike previous ATRAC codecs, there's no QMF, this is a standard MDCT
codec.

The FATE tests for MSVC versions older than 2013 are untested in FATE

This does require libmysofa with today's latest commit (08f243d1ec).
They already had a pkg-config file, but the dependencies weren't setup right. Until now.
This should be included as `<lilv/lilv.h>`, same as is done in af_lv2.c.
Forcing the extra lilv-0 breaks platforms where the include dir is
`/usr/include/lilv/lilv.h` rather than
`/usr/include/lilv-0/lilv/lilv.h`.
The new include path works for both, because the `pkg-config --cflags`
includes `-I/usr/include/lilv-0`.
It exists, so why not use it? Helps one get rid of additional
search path related flags in addition to PKG_CONFIG_{PATH,LIBDIR}
when utilizing a cross-prefix separate from the sysroot.
This can "demux" .vpy files. Autodetection of .vpy scripts is
intentionally not done, because it would be a major security issue. You
need to force the format, for example with "-f vapoursynth" for the
FFmpeg CLI tools.
Some minor code copied from other LGPL parts of FFmpeg.
I did not find a good way to test a few of the more obscure VS features,
like VFR nodes, compat pixel formats, or nodes with dynamic size/format
changes. These can be easily implemented on demand.
Without properly grouping the checks, the second test would execute for
MSVC cl.exe, which results in configure getting stuck since cl.exe -? is

-stack-alignment=16) hasn't actually been supported for quite some
time; current clang versions use -mstack-alignment=16 for the same.
Actually testing for that parameter would be a different change
though, since it has a real risk of changing behaviour on any other
platform where clang is used.

Previously the bit pattern for the endianness test was declared as a
global, instead of a local, variable. This ensures that the pattern
appears unchanged in the object file and is not optimized out.
Right now, if someone configures ffmpeg with for example --enable-nvenc they will
get an error message complaining about missing cuda.
This is very confusing and already has lead people into installing the CUDA SDK,
even though it's not what they need.
This will make it complain about ffnvcodec instead.

External headers are no longer welcome in the ffmpeg codebase because they
increase the maintenance burden. However, in the NVidia case the vanilla
headers need some modifications to be usable in ffmpeg therefore we still
provide them, but in a separate repository.
The external headers can be found at
https://git.videolan.org/?p=ffmpeg/nv-codec-headers.git
Fate-source is updated because of the deleted files, and dynlink_loader.h
license headers were updated with the standard FFmpeg headers.

Merged-by: James Almer <jamrial@gmail.com>
The GCC generated import libraries don't work properly when being imported
by MSVC, resulting in missing symbols at runtime.
This reverts 5b5365fe9 and partially reverts changes from 98a9b1f0d
This reverts commit 67c72f08a4.
While the linker produced import libraries might work with MSVC in
simple test cases, they don't if e.g. linking to multiple GNU ld
produced import libraries at the same time. (They end up importing
functions from the wrong libraries.) The ones produced by dlltool
work fine though.

Currently the Windows CC_IDENT is ended with '\r\n'. "head -n1" will not
remove the '\r' and this is causing building error in Chromium.
This CL adds "tr -d '\r'" to remove '\r' in the CC_IDENT string. Since in
most cases '\r' only appears at the end of a string/line, this should
work in most cases.
See example:
printf "hello\r\nworld\r\n" | head -n1 | hd
00000000 68 65 6c 6c 6f 0d 0a |hello..|
printf "hello\r\nworld\r\n" | head -n1 | tr -d '\r' | hd

SDL2 uses SDLCALL to specify a calling convention. On OS/2, it's defined
to `_System' which is similar to `_cdecl' but does not prepend '_'.
After all, without a header, a function is used without `_System'. And
linker will try to `_func' but fail because the function is `func' not
`_func'.

This was added in early 2013 and abandoned several months later; as far as
I can tell, there are no external users. Future OpenCL use will be via
hwcontext, which requires neither special OpenCL-only API nor global state
in libavutil.
All internal users are also deleted - this is just the unsharp filter
(replaced by unsharp_opencl, which is more flexible) and the deshake filter
(no replacement).
Intended to replace existing opencl mode of the unsharp filter.
Supports many more pixel formats and works without immediate upload
and download of frame data. The options are compatible with the
existing filter.
Using cl_arm_import_memory. Unfortunately, despite this not being a
standard extension, the function clImportMemoryARM() is not accessible
via clGetExtensionFunctionAddressForPlatform(). This means that it has
to be linked directly to the ARM OpenCL binary, so making a portable
binary is not possible as it is with all other mapping extensions.
this will simplify libvpxenc/dec.c and ensure more stable versions of
the codecs are present.

This was predictably nightmarish, given how ridiculous mpeg4 is.
I had to stare at the cuvid parser output for a long time to work
out what each field was supposed to be, and even then, I still don't
fully understand some of them. Particularly:
vop_coded: If I'm reading the decoder correctly, this flag will always
be 1 as the decoder will not pass the hwaccel any frame
where it is not 1.
divx_flags: There's obviously no documentation on what the possible
flags are. I simply observed that this is '0' for a
normal bitstream and '5' for packed b-frames.
gmc_enabled: I had a number of guesses as to what this mapped to.
I picked the condition I did based on when the cuvid
parser was setting flag.
Also note that as with the vdpau hwaccel, the decoder needs to
consume the entire frame and not the slice.

The only purpose of dllexport (which is set while building the library
that exports the symbols) is to have the linker automatically
export such symbols into a DLL without using a def file - it doesn't
affect the generated code.
For both MSVC and mingw builds, this isn't essential since we override
what symbols to export via an autogenerated def file instead.
Update a comment in configure to refer to the right concept.
With lld, this avoids warnings about duplicate export directives,
when some symbols are requested to be exported both via dllexport
attributes and via the autogenerated def file.
This also reduces the number of lines of code marginally.

This is mostly straight-forward. The weird part is that it should
just work for mpeg1, but I see corruption in my test cases, so I'm
going to try and fix that separately.
By putting the call in a subshell, the problem of it spilling
cleanup-decision from a previous library to other libraries is avoided.
For example, it could have already cleaned up cuda_extralibs in a
previous library that depended on cuda. Then when it gets to avutil, it
will never pick up the dependency of avutil to cuda, which depends on
libdl, which in turn results in a missing -ldl extralib, resulting in
link failures in certain configurations.
