This simplifies the code as there is no other place the error buffer
is needed, so the av_err2str helper macro can be used.

av_err2str which is a wrapper for av_strerror already calls
strerror_r if available and if not has a fallback for the other
error codes that would be handled by that, so manually calling
strerror again if it fails is not necessary.

This filter currently keeps the input timebase, but produces CFR output.
It is thus simpler to use 1/output fps as the output timebase.
Also, set output frame durations.
Currently it would essentially change the find_stream_info setting for
the file it was specified for and all following files, which is unusual
and somewhat unexpected behaviour for a per-file option and not even
documented to behave like this.

VSETVLI xd, x0, ...' has rather nonobvious semantics:
- If xd is x0, then it preserves the current vector length.
- If xd is not x0, it sets the vector length to the supported maximum.
Also somewhat confusingly, while VMV.X.S always does its thing
regardless of the selected vector length, VMV.S.X does _nothing_ if the
selected vector length is zero.
So the current code breaks fails to initialise the accumulator if we
are unlucky to have a selected vector length of zero on entry. Fix it
by forcing the vector length to one.
The binkaudio decoders don't need mdct or sinewin at all;
and binkaudio_dct doesn't need rdft directly (but nevertheless
uses it indirectly via dct).

Add an AV_PIX_FMT_NE macro for RGB32FBE/RGB32FLE and also one for
RGBA32FBE/RGBA32FLE for packed 32-bit float RGB samples, and also
packed 32-bit float RGBA samples, respectively.

Currently, it is accessed via a pointer (ff_celt_window)
exported from opustab.h which points inside a static array
(ff_celt_window_padded) in opustab.h. Instead export
ff_celt_window_padded directly and make opustab.h
a static const pointer pointing inside ff_celt_window_padded.
Also mark all the declarations in opustab.h as hidden,
so that the compiler knows that ff_celt_window has a fixed
offset from the code even when compiling position-independent
code.

P012, Y212 and XV36 are used for 12bit content in FFmpeg VAAPI, so
these formats should be used in FFmpeg QSV too, however the SDK only

XV30 is used for 10bit 4:4:4 content in FFmpeg VAAPI, so XV30 should be
used for 10bit 4:4:4 content in FFmpeg QSV too because QSV is based on

nothing with the alpha in Y410, so this commit fudged a mapping between
