Summary of the bug:
If you have a short audio and try to get only the non silent parts then
amplify the non silent part, it just hangs. If the duration is 1.5 seconds
for example, it works just fine.
How to reproduce:
{{{
% ffmpeg -f lavfi -i "sine=frequency=1000:duration=0.5" -y test.wav ;
ffmpeg -i test.wav -af
'silenceremove=stop_periods=-1:stop_duration=0.5:stop_threshold=-70dB,loudnorm,dynaudnorm=g=3:f=200'
-y b.flac
