#9889: Silenceremove filter fails to stop trimming if audio does not start
silent
----------------------------------+--------------------------------------
Reporter: y3kcjd5 | Type: defect
Status: new | Priority: normal
Component: avfilter | Version: git-master
Keywords: | Blocked By:
Blocking: | Reproduced by developer: 0

----------------------------------+--------------------------------------
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.
