[MPlayer-users] audio-filter volume Oliver Seitz Wed Jul 21 06:00:23 2010

Hi.

The manpage informs me about a useful feature:

/quote/
volume[=v[:sc]]
              Implements  software  volume control. [...]
This filter has a second feature: It measures the overall maximum sound level and prints out that level when MPlayer exits.
\quote\

But where does it print that to? I can not see any output like that on stdout or stderr, even with "-v -v".
