The loader ensures only that functions with tagged supported extensions
exist, rather than ensuring only those with supported extensions are
loaded.
As the init function uses Vulkan functions, whose loading requires them
to have the extension flags set, the extension flags are guaranteed
to also exist at this point.
Can be used to configure libplacebo's underlying raw options, which
sometimes includes new or advanced / in-depth settings not (yet) exposed
by vf_libplacebo.
This new upstream struct simplifies params struct management by allowing
them to all be contained in a single dynamically allocated struct. This
commit switches to the new API in a backwards-compatible way.
The only nontrivial change that was required was to handle
`sigmoid_params` in a way consistent with the rest of the params
structs, instead of setting it directly to the upstream default.
This prevents code duplication in the source form by calling the parse
code that was moved to avcodec last commit. The code will be duplicated
in binary form for shared builds (it's not that large), but for source
code it will only exist in one location now.

Add a full parser to libavcodec for AV_CODEC_ID_JPEGXL. It finds the
end of the stream in order to packetize the codec, and it looks at
the headers to set preliminary information like dimensions and pixel
format.
Note that much of this code is duplicated from avformat/jpegxl_probe.c,
but that code will be removed and call this instead in the next commit.

Before this commit, the decoder erroneously assumes that the AVFrame
passed to the receive_frame is the same one each time. Now it keeps an
internal AVFrame to write into, and copies it over when it's done.

Fixes an error that's caused by decoding a grayscale JXL image after an
RGB image is decoded, with the same decoder instance.

OpenVINO API 2.0 was released in March 2022, which introduced new
features.
This commit implements current OpenVINO features with new 2.0 APIs. And
will add other features in API 2.0.
Please add installation path, which include openvino.pc, to
PKG_CONFIG_PATH mannually for new OpenVINO libs config.

So far, AV_READ_TIME would return the cycle counter. This posed two
problems:
1) On recent systems, it would just raise an illegal instruction
exception. Indeed RDCYCLE is blocked in user space to ward off some
side channel attacks. In particular, this would cause the random
number generator to crash.
2) It does not match the x86 behaviour and the apparent original intent
of AV_READ_TIME in the functional code base (outside test cases).
So this replaces the cycle counter with the time counter. The unit is
a platform-dependent constant fraction of time, and the value should be
stable across harts (RISC-V lingo for physical CPU thread).
It is currently probably not possible for it to be negative as
the needed 2Mb input buf size is not achievable. But it is more
robust to check for it too.
If it would become negative than code like
s->samples[0][n] = s->samples[0][s->nb_samples + n];
would crash

The fate-run.sh shell script exports LC_ALL=C before invoking the
test executables; this is probably done for consistency.
When executing Windows binaries with Wine, it normally handles
UTF-8 command line parameters just fine - but with LC_ALL set to
C, it treats them as plain ASCII.
As the unicode command line parameters wasn't the main thing
being tested here, just convert them to plain ASCII, for
portability. This fixes the test for all test configurations that
use Wine.

ddc1cd5cdd defined WIN32_LEAN_AND_MEAN
globally, which makes for much fewer transitive includes from
windows.h. With that define, CoTaskMemFree no longer gets
implicitly declared by just including windows.h, but one has to
include the right header objbase.h too.
That commit caused ole32 to no longer get detected, which caused
dxva2 to no longer be enabled. This gets fixed by this patch.
