Function av_fft_init

pub unsafe extern "C" fn av_fft_init(
    nbits: i32,
    inverse: i32,
) -> *mut FFTContext

Set up a complex FFT. @param nbits log2 of the length of the input array @param inverse if 0 perform the forward transform, if 1 perform the inverse @deprecated use av_tx_init from libavutil/tx.h with a type of AV_TX_FLOAT_FFT
