I found out what my problem is; it's that the dynaudnorm filter is returning EAGAIN; which means I need to send it more PCM frames.

Now, I'm trying to integrate this filter into a real time player context; and I would like to avoid audio artifacts. I've been playing with various options that the filter has; but I can't seem to find one where it would work better in the real time context.

Does anyone know what the correct parameters would be so it works frame by frame or in a much smaller frame size so we can avoid audio artifacts?
Alternatively, is there another ffmpeg filter better suited to real time dynamic range compression or volume normalization?
