  • avcodec/jpeg2000 : Simplify exp2fi for numbers used here

    17 février 2024, par Andreas Rheinhardt
    avcodec/jpeg2000 : Simplify exp2fi for numbers used here

    The call to ff_exp2fi() here always uses arguments in the normal
    
range, so that the branches in ff_exp2fi() are unnecessary.
    
This is so because JPEG2000 itself only supports up to
    
128 bits per component per pixel (we only support far less) ;
    
furthermore, expn is always 0..31 for the decoder and also
    
sane for the encoder, so that the difference between these
    
two values is always in the normal range of -126..128.
