previouslly, it only was an issue with 32-bit clang from msys2's
mingw32 repo, however, at some point with an update to gcc 12.2.0,
the same issue popped up. Tested with a clean clone of ffmpeg, and even
tested with n5.0, but the issue persists, so I presume it's a compiler
issue.

This filter implements frame rate down/upsampling using nvidia's
Optical Flow FRUC (Frame Rate Up Conversion) library. It's neat because
you get realtime interpolation with a decent level of quality. It's
impractical because of licensing.
I have no actual intention to merge this, as it doesn't eve
The NvOFFRUC library provides a GPU accelerated interpolation feature
based on nvidia's Optical Flow functionality. It's able to provide
reasonably high quality realtime interpolation to increase the frame
rate of a video stream - as opposed to vf_framerate that just does a
linear blend or vf_minte

MSDK/VPL uses 420 chroma format as default to encode RGB, and this is
not a proper usage. Now enable 444 encoding for RGB input by default.
RGB is encoded using 444 chroma format when user doesn't specify the
profile or uses rext profile, otherwise, 420 is used.

The current official docs mistakenly pick up the override macros
in libavcodec/tableprint_vlc.h as the canonical definitions of
functions like av_free() and av_freep(), causing the docs to
link to those #defines instead of the
