             Reporter:  y3kcjd5   |                     Type:  defect
               Status:  new       |                 Priority:  normal
            Component:  avfilter  |                  Version:  git-master

 How to reproduce:
 {{{
 ffmpeg -loglevel verbose -ss 0.001 -i dummysine.wav -filter:a
 "silenceremove=start_periods=1:start_threshold=-200dB:detection=peak:window=0"
 -map 0:a -c libmp3lame -q 0 "tryout.mp3"
 }}}
 FFmpeg reports no data encoded, and the resulting file contains no audio.
 Removing the -ss tag will cause expected behavior to be restored,
 presumably because sine waves start from 0 amplitude.
