[Libav-user] ff_iir_filter_init_coeffs

[Mika Rajala]

Hi

I'd like to use the iirfilter in ffmpeg to filter out noise frequencies in my audio.

For this, I found the iirfilter.h in libavcodec

But i don't know how to use it properly, any tutorials / tips?

The first function seems a bit odd even.

ff_iir_filter_init_coeffs wants a void * avc which is something mysterious.
