aa79d13f51 avformat/cafenc: derive Opus frame size from the relevant stream parameters 
Use the stream duration as last resort, as an off-by-one result of the
"st->duration / (caf->packets - 1)" calculation can break playback on some
devices.
Also, don't write the sample_rate value propagated by encoders like libopus.
The sample rate of the audio fed to it is irrelevant after being encoded.

Fixes ticket #9930.

74e8541bab x86/tx_float: generalize iMDCT 
To support non-aligned buffers during the post-transform step, just iterate
backwards over the array.

This allows using the 15xN-point FFT, with which the speed is 2.1 times
faster than our old libavcodec implementation.

ace42cf581 x86/tx_float: add 15xN PFA FFT AVX SIMD

The shuffles in the 15pt dim1 are seriously expensive. Not happy with it,
but I'm contempt.

Can be easily converted to pure AVX by removing all vpermpd/vpermps
instructions.

686096739b fftools/ffmpeg_filter: configure min_hard_comp unconditionally 
There are two issues here. Firstly, the floating-point comparison
is always true. Seconly, the code depends on the default value of
min_hard_comp implicitly, which can be dangerous.

Partially fixes ticket 9859.

a2d95928c3 avformat/movenc: Write auxi box for animated AVIF with alpha 
According to the HEIF specification (ISO/IEC 23008-12) Section
7.5.3.1, tracks with handler_type 'auxv' must contain a 'auxi' box
in its SampleEntry to notify the nature of the auxiliary track to the
decoder.

The content is the same as the 'auxC' box. So parameterize and re-use
the existing function.

Rémi Denis-Courmont
08edacc248 lavc/aacpsdsp: precompute constant factors 
The input complex factors are constant for each iterations. This
substitudes 4 loads, 2 additions and 2 subtractions per iteration of
the inner-loop with another 4 loads. Thus effectively 4 arithmetic
operations per iteration of the inner loop are avoided, i.e. 24
operations per iteration of the outer loop, or 24 * (n - 1) operations
in total.

If the inner loop is not unrolled by the compiler, this also might
also save some pointer arithmetic as most instruction sets do not
have addressing modes with negated register offsets (12 - j). Unless
the compiler is optimising for code size, this is unlikely though.
