Otherwise they'd be silently ignored if received by the filtering thread
before the filtergraph can be initialized, which would make the output
dependent on the order in which frames from different inputs arrive.
As previously for decoding, this is merely "scaffolding" for moving to a
fully threaded architecture and does not yet make filtering truly
parallel - the main thread will currently wait for the filtering thread
to finish its work before continuing. That will change in future commits
after encoders are also moved to threads and a thread-aware scheduler is
added.
Avoid making decisions based on current graph input state, which makes
the output dependent on the order in which the frames from different
inputs are interleaved.
Makes the output of fate-filter-overlay-dvdsub-2397 more correct - the
subtitle appears two frames later, which is closer to its PTS as stored
in the file.

win32 typically doesn't have unistd.h, so always including it will break
MSVC builds. The usage of those POSIX functions are already guarded by
_WIN32, so use that to guard unistd.h include as well.

The earlier code writes the file and then tries to patch up
the size later. This is avoidable for the common case of
a single image because one can know the complete size
in advance and write it.
Fixes ticket #4609.

The libvmaf filter was doing substring checks in place of string equality
comparisons. This led to a bug when the user specified the pooling method
"harmonic_mean", since "mean" was checked first and the substring comparison
returned true. This patch changes all substring comparisons for string equality
comparisons. This is both correct and more efficient than the existing method.

The current logic for detecting frames that are too small for the
algorithm does not account for chroma sub-sampling, and so a sample
where the luma plane is large enough, but the chroma planes are not
will not be rejected. In that event, a heap overflow will occur.
This change adjusts the logic to consider the chroma planes and makes
the change to all three bwdif implementations.

This patch allows the JXL parser to parse sequences of extremely small

According to ISO/IEC 14996-12, size == 1 means a 64-bit extended-size
field occurs *after* the 32-bit box type, not before. This fix should
allow correct parsing of JXL files with extended-size boxes.

mfxExtendedDeviceId mightn't be supported in certain configurations of
oneVPL on Linux, so we can't ensure a property filter for
mfxExtendedDeviceId.DeviceID or mfxExtendedDeviceId.VendorID works as
expected. This fixed the issue mentioned in [1]

libvpl deprecated some symbols (e.g. MFX_EXTBUFF_VPP_DENOISE2 is used to
replace MFX_EXTBUFF_VPP_DENOISE), however the new symbols aren't support
by MediaSDK runtime. In order to support the combination of libvpl and
MediaSDK runtime on legacy devices, we continue to use the deprecated
symbols in FFmpeg. This patch added -DMFX_DEPRECATED_OFF to CFLAGS to
silence the corresponding compilation warnings.
