  *
  * This script skips to the next silence in the file. The
  * intended use for this is to skip until the end of an
  * opening sequence, at which point there's often a short
  * period of silence.
  *
  * The default keybind is F3. You can change this by adding
  * the following line to your input.conf:
  *     KEY script-binding skip-to-silence
  *
  * In order to tweak the script parameters, you can place the
  * text below, between the template markers, in a new file at
  * script-opts/skiptosilence.conf in mpv's user folder. The
  * parameters will be automatically loaded on start.
  *
  * Dev note about the used filters:
  * - `silencedetect` is an audio filter that listens for silence and
  * emits text output with details whenever silence is detected.
  * Filter documentation: https://ffmpeg.org/ffmpeg-filters.html
****************** TEMPLATE FOR skiptosilence.conf ******************
#--(#number). Maximum amount of noise to trigger, in terms of dB. Lower is more sensitive.
silence_audio_level=-40
#--(#number). Duration of the silence that will be detected to trigger skipping.
silence_duration=0.7
#--(0/#number). The first detcted silence_duration will be ignored for the defined seconds in this option, and it will continue skipping until the next silence_duration.
# (0 for disabled, or specify seconds).
ignore_silence_duration=1
#--(0/#number). Minimum amount of seconds accepted to skip until the configured silence_duration.
# (0 for disabled, or specify seconds)
min_skip_duration=0
#--(0/#number). Maximum amount of seconds accepted to skip until the configured silence_duration.
# (0 for disabled, or specify seconds)
max_skip_duration=120
#--(yes/no). Default is muted, however if audio was enabled due to custom mpv settings, the fast-forwarded audio can sound jarring.
force_mute_on_skip=no
#--(yes/no). Display osd messages when actions occur.
osd_msg=yes
