+Skipping silence using libav filters
+....................................
+
+The following code uses the libav silencedetect filter to skip silence at the beginning of a file. It works by loading
+the filter, then parsing its output from mpv's log. Thanks to Sean DeNigris on github (#202) for the original code!
+
+.. code:: python
+
+ #!/usr/bin/env python3
+ import sys
+ import mpv
+
+ p = mpv.MPV()
+ p.play(sys.argv[1])
+
+ def skip_silence():
+ p.set_loglevel('debug')
+ p.af = 'lavfi=[silencedetect=n=-20dB:d=1]'
+ p.speed = 100
+ def check(evt):
+ toks = evt['event']['text'].split()
+ if 'silence_end:' in toks:
+ return float(toks[2])
+ p.time_pos = p.wait_for_event('log_message', cond=check)
+ p.speed = 1
+ p.af = ''
+
+ skip_silence()
+ p.wait_for_playback()
