    opusdsp : adjust and optimize C function to match assembly

    The C and asm versions behaved differently _outside_ of the codec.
    

    The C version returned pre-multiplied 'state' for the next execution
    
to use right away, while the assembly version outputted non-multiplied
    
'state' for the next execution to multiply to save instructions.
    
Since the initial state when initialized or seeking is always 0,
    
and since C and asm versions were never mixed, there was no issue.
    

    However, comparing outputs directly in checkasm doesn't work without
    
dividing the initial state by CELT_EMPH_COEFF and multiplying the
    
returned state by CELT_EMPH_COEFF for the assembly function.
    

    Since its actually faster to do this in C as well, copy the behavior the
    
asm versions use. As a reminder, the initial state 0 is divided by
    
CELT_EMPH_COEFF on seek and init (just in case in the future this is
    
changed, its technically more correct to init with CELT_EMPH_COEFF than 0,
    
however when seeking this will result in more audiable pops, unlike with 0
    
where the output gets in sync over a few samples).

  • Match radial lens distortion of two videos taken with two different actioncams with different FOV

    24 mai 2018, par Fabien Biller

    I have two different actioncams with different k1 and k2. How do I calculate k1 and k2 for one video not to be "defished", but have the same amount of distortion as the other video ?
