mesvam / ff-silence

mpv script to automatically fast forward through silences

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)

How it works

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.

Options

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
