FFmpeg and FIR filtering – Stack Overflow

I would like to use the FIR filter function from the FFmpeg library. I would like to find similar functions that are implemented for IIR filter:

ff_iir_filter_init_coeffs(),ff_iir_filter()

So I need simple functions like fir_init_coef() and fir_filter() – prepare coefficients and .use them for filtering. Nothing more.

Coefficients itself will be calculated outside.

I already use the resampling part of the FFmpeg library. There was a good example for this functionality. But not for FIR.

What functions from FFmpeg lib can you recommend for this?
