Fast forward through silences and quiet parts of audio. This is especially useful on videos where the speaker uses many long pauses. Activate with Ctrl+A or enable by default using the enabled option (add script-opts-append=ff_silence-enabled=true to mpv.conf)

Silences are detected by ffmpeg's silencedetect filter when the volume is below silence_threshold for a duration longer than silence_duration. When a silence is found, the playback speed is increased by a constant multiplicative factor speedup until audio is found.

These can be set as script options, e.g. --script-opts-append=silence_threshold=-18

• enabled: set to true to enable at startup (default false)
• speedup: speedup factor during silences (default 2.83)
• silence_threshold: volume threshold (in dB) that will be detected as silence (default -23)
• silence_duration: minimum duration (in seconds) that will be detected as silence (default 0.25)
• speed_change_osd: set to true to display an indicator every time the speed changes (default false)
• debug: set to true to show debug output on the commandline (default false)

Some parameters can be adjusted during playback with the following default key bindings

• Ctrl+A = toggle
• Alt++ = increase speedup
• Alt+- = decrease speedup
• Ctrl+* = increase silence_threshold
• Ctrl+/ = decrease silence_threshold
• Alt+* = increase silence_duration
• Alt+/ = decrease silence_duration
