#9889 closed defect (fixed)

Silenceremove filter fails to stop trimming if audio does not start silent

Reported by: y3kcjd5 Owned by:

Blocking: Reproduced by developer: no
Analyzed by developer: no


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.
